Tomahawk tree2
Greetings,
I have been doing some trial and error experiments with tomahawk´s tree2
component and I have some questions:
1. How does the component knows which nodes have been opened, where is
this state kept, in order to choose between the opened and closed images?
This is the sample code from the demos available:
<t:tree2 id="serverTree" value="#{treeBacker.treeData}"
var="node"
varNodeToggler="t" clientSideToggle="false">
<f:facet name="person">
<h:panelGroup>
<t:graphicImage
value="images/yellow-folder-open.png"
rendered="#{t.nodeExpanded}" border="0"
/>
<t:graphicImage
value="images/yellow-folder-closed.png"
rendered="#{!t.nodeExpanded}" border="0"
/>
<h:outputText value="#{node.description}"
styleClass="nodeFolder" />
</h:panelGroup>
</f:facet>
<f:facet name="foo-folder">
<h:panelGroup>
<t:graphicImage
value="images/yellow-folder-open.png"
rendered="#{t.nodeExpanded}" border="0"
/>
<t:graphicImage
value="images/yellow-folder-closed.png"
rendered="#{!t.nodeExpanded}" border="0"
/>
<h:outputText value="#{node.description}"
styleClass="nodeFolder" />
<h:outputText value=" (#{node.childCount})"
styleClass="childCount"
rendered="#{!empty node.children}" />
</h:panelGroup>
</f:facet>
<f:facet name="bar-folder">
<h:panelGroup>
<t:graphicImage
value="images/blue-folder-open.gif"
rendered="#{t.nodeExpanded}" border="0"
/>
<t:graphicImage
value="images/blue-folder-closed.png"
rendered="#{!t.nodeExpanded}" border="0"
/>
<h:outputText value="#{node.description}"
styleClass="nodeFolder" />
<h:outputText value=" (#{node.childCount})"
styleClass="childCount"
rendered="#{!empty node.children}" />
</h:panelGroup>
</f:facet>
<f:facet name="document">
<h:panelGroup>
<h:commandLink immediate="true"
styleClass="#{t.nodeSelected ?
'documentSelected':'document'}"
actionListener="#{t.setNodeSelected}"
action="#{treeBacker.nodeSelected}">
<t:graphicImage
value="images/document.png" border="0" />
<h:outputText value="#{node.description}"
/>
<f:param name="docDesc"
value="#{node.description}" />
<f:param name="docType"
value="#{node.type}" />
</h:commandLink>
</h:panelGroup>
</f:facet>
</t:tree2>
In the above I dont understand what is the attribute varNodeToggler? (and
I think that here is where the answer to my question lies
)
2. I am trying to develop a web-based file explorer and so far I can
paint the selected item´s data on the right region of the page using an
action mapping on the node, but I also need that according to a click on a
folder on the right pane, the tree opens on the left pane the clicked folder
(in a similar fashion to all file explorers where there´s some sort of
bidirectional listener mechanism between both panes).
3. Finally, if anyone has a reference to some more examples on the use
of this component and documentation please let me know, ´cause I´m a little
scarce on docs and examples (So far I have just checked the faces wiki)

Wow, not sure why the source zip is out of date or if there is an
extra java file lying around. Here is the code in SVN:

Andrew, one last request: the TreeBean found in the source files
(jsfCompAA-source.zip) is incomplete:
/**

package warSource.net.sf.jsfcomp.aa.tree.examples;
/**

Would you mind copying me the full source for this Bean.
Thanks a lot and best regards,

Answer for number 2:
1) if you want to stick with the "standard" implementation, the node
expanded state is kept in the tree state in the form of indexes. So:
A (0)
--A1(0)
--B1(1)
If you want to expand B1 use the indexes shown in the parenthesis.
Specifically "0:0"
Or 2) use my nodes from http://jsf-comp.sf.net.
I my node has an expanded and selected property. I used a custom tree state
object to delegate the check for expanding or collapsing to these nodes. So
if you use this code, you can simply: node.setExpanded(true);

RE: Tomahawk tree2
Posted by Jorge Vásquez <jv...@3eyegroup.com>.
But precisely my question is which class provides the implementation for
the methods: nodeSelected, setNodeSelected, nodeExpanded
I have been looking in the source files from tomahawk and have found that
the direct methods are:
public boolean isNodeExpanded()
public void setNodeSelected(ActionEvent event)
public boolean isNodeSelected()
Which are implemented by the class:
org.apache.myfaces.custom.tree2.UITreeData, which uses a delegate from a
TreeState implementor, and the TreeModel itself also has a reference to a
TreeState, so I guess that the answer lies in the TreeState class
This kind
of answers my first question, still 2 and 3 going

JV

Exactly, the varNodeToggler is a session bean created by the component. The
varNodeToggler will stored the state of the tree and be used by the
framework to render the tree.... at least, this is what i understand from my
expirement.

RE: Facelets Layout / Command Button Issue
Posted by Tom Innes <To...@allTiers.com>.
Thanks for the advice David.
I have tried the f:view / h:form on main page inside the ui:composition tag
and outside the ui:composition tag and I basically get the same error that
the command buttons must be inside an h:form.
I have tried using an ui:insert on the main page with the same issue that
the command buttons must be inside a h:form.
Have you successfully placed command buttons inside a layout on any of the
facelets work you have done?
Meanwhile I have printed out the documentation and will try some of the
other things you have suggested. Hopefully something will eventually
work!!!!

Tom,
I think you need to review the Facelets Guidebook:
<https://facelets.dev.java.net/nonav/docs/dev/docbook.html#template-composit
ion>
https://facelets.dev.java.net/nonav/docs/dev/docbook.html#template-compositi
on
ui:composition removes everything from the page except for what is inside
your tags. That means you LOST your f:view and h:form tags and that seems
to match your posted errors. I recommend your main page use a different tag
such as ui:decorate, ui:insert, or ui:fragment (not reallly recommended
because you must create a binding name).
Also, you should keep requests like this on the facelets list (I know you
subscribe to both, I've seen your postings) and just have patience if you
want help. Or review the documentation slowly and find the nicely
documented "quirks" or each taglib. Again, the Facelets docbook is an
excellent guide to print out and keep by your desk. I did when I first
started with Facelets. See you on the facelets list!

David

Subject: Facelets Layout / Command Button Issue
I apologize, if this is the correct group for my question.
I am trying to create a facelets layout hierarchy for a crud based
application I am building in JSF. I have a proto type working fine in JSF
and now I want to use facelets to standardize the layouts before we begin
the actual application. I have created a base layout that defines things
like message blocks and such. I would like to create a QBE layout that
includes my base layout and a button panel that has buttons like find,
clear, etc.
The problem is that I am unable to place a h:commandbuttom inside the
layout. For Instance
aQBEButtonPanel.xhtml
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:ui="http://java.sun.com/jsf/facelets"
xmlns:h="http://java.sun.com/jsf/html">

action="#{theQBEController.action.find}" id="findButton"/>
<h:commandButton value="Clear"

immediate="true"/>
<h:commandButton value="Add"
action="#{theFormController.action.add}" id="addButton" immediate="true"/>
</h:panelGrid>
</ui:composition>
</html>
I have a base Layout defined as

Tom,
I think you need to review the Facelets Guidebook:
https://facelets.dev.java.net/nonav/docs/dev/docbook.html#template-compositi
on
ui:composition removes everything from the page except for what is inside
your tags. That means you LOST your f:view and h:form tags and that seems
to match your posted errors. I recommend your main page use a different tag
such as ui:decorate, ui:insert, or ui:fragment (not reallly recommended
because you must create a binding name).
Also, you should keep requests like this on the facelets list (I know you
subscribe to both, I've seen your postings) and just have patience if you
want help. Or review the documentation slowly and find the nicely
documented "quirks" or each taglib. Again, the Facelets docbook is an
excellent guide to print out and keep by your desk. I did when I first
started with Facelets. See you on the facelets list!
Regards,
David

Subject: Facelets Layout / Command Button Issue
I apologize, if this is the correct group for my question.
I am trying to create a facelets layout hierarchy for a crud based
application I am building in JSF. I have a proto type working fine in JSF
and now I want to use facelets to standardize the layouts before we begin
the actual application. I have created a base layout that defines things
like message blocks and such. I would like to create a QBE layout that
includes my base layout and a button panel that has buttons like find,
clear, etc.
The problem is that I am unable to place a h:commandbuttom inside the
layout. For Instance
aQBEButtonPanel.xhtml
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:ui="http://java.sun.com/jsf/facelets"
xmlns:h="http://java.sun.com/jsf/html">
<ui:composition>
<h:panelGrid rows="3" columns="1">
<h:commandButton value="Find"
action="#{theQBEController.action.find}" id="findButton"/>
<h:commandButton value="Clear"
action="#{theQBEController.action.clear}" id="clearButton"
immediate="true"/>
<h:commandButton value="Add"
action="#{theFormController.action.add}" id="addButton" immediate="true"/>
</h:panelGrid>
</ui:composition>
</html>
I have a base Layout defined as
aBaseLayout.xhtml
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml"

</div>
<div id="center">
<ui:insert name="content">
<div>
<ui:include src="content.xhtml"/>
</div>
</ui:insert>
</div>
</body>
</html>
And the countryQBE.xhtml is defined as follows
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"

<ui:composition

<ui:param name="theQBEController"
value="#{countryQBEController}"/>
<ui:param name="theFormController"
value="#{countryFormController}"/>
<ui:define name="content">
<h:panelGrid columns="3">
Bunch of Input
Fields
Etc
The problem is that I get this exception
23:11:04,062 INFO [STDOUT] 6-Jun-2006 11:11:04 PM
com.sun.facelets.FaceletViewHandler handleRenderException

java.lang.IllegalArgumentException: Component findButton must be embedded
in an form
at

Now the commandButtons cannot be contained in a different Form than the
Input Fields otherwise the Model is not updated. Does anybody know how to
place a command button in a facelets layout?

Re: Tomahawk tree2
Posted by Romain PELISSE <ro...@atosorigin.com>.
"In the above I don't understand what is the attribute varNodeToggler?
(and I think that here is where the answer to my question lies... )"
Exactly, the varNodeToggler is a session bean created by the component.
The varNodeToggler will stored the state of the tree and be used by the
framework to render the tree.... at least, this is what i understand
from my expirement.
