RE: selectionlistener for tree2
Sean,
I have created tree2 and as per this email thread, I am getting action
events in my bean whenever I click on either "images" or "description text".
But the only problem is when I click on "+" or "-" images I and not getting
the action events as these images are (I guess) put bye the tree2
component...
So how do I get action events on "+" and"-" images for the consistence
behavior...
Thanks
Mihir Solanki

Subject: Re: selectionlistener for tree2
It looks like your problem is that you have the method name as
processEvent in your actionListener attribute but you've defined the
method name as processAction.
If you want the tree to keep track of your selected nodes for you then
you *must* use:
actionListener="#{t.setNodeSelected}"
But if you want to handle things yourself, then there is nothing wrong
with what you are trying to do.

You need to specify a component mapping in your faces-config.xml.
Note the default components are all mapped in a faces-config.xml that
ships with the JAR file. So this default config sets up all of the
components for you.
If you want to provide your own (as you are trying to do) you need to
override the component in question in the faces-config.xml that goes
in your WEB-INF directory. You configure the XML exactly the same as
for any component and renderkit that you configure through JSF (so any
tutorial/book covering that topic should be able to help.)
See this thread in the archives for some more details:

Re: selectionlistener for tree2
Posted by Sean Schofield <se...@gmail.com>.
You need to specify a component mapping in your faces-config.xml.
Note the default components are all mapped in a faces-config.xml that
ships with the JAR file. So this default config sets up all of the
components for you.
If you want to provide your own (as you are trying to do) you need to
override the component in question in the faces-config.xml that goes
in your WEB-INF directory. You configure the XML exactly the same as
for any component and renderkit that you configure through JSF (so any
tutorial/book covering that topic should be able to help.)
See this thread in the archives for some more details:

Re: selectionlistener for tree2
Posted by Rob Decker <ro...@objectsource.org>.
I think it is accurate to say it doesn't support action/actionListener(s). If it did
you'd be able to set the action/actionListener(s) attributes/elements on/in a tree2.
It does have a few action handlers (for selected and toggle) but it doesn't itself let
you set an action/actionListener(s) that get called when either of those things occur.
I think mixing client/server tree functionality isn't a good idea. Why fight with
supporting each in one component when you can have two components each dedicated to
the task at hand. It isn't like you're going to use client side toggle and switch
dynamically to server side toggle under certain conditions.
My code doesn't set selected when a user clicks the plus/minus nav images because
there is no support for setting an actionListener (calling setSelectedNode from
toggleExapanded would work without an actionListener).
And speaking of hard pressed things to find that tree doesn't support...try setting
it's width, border, background color, style, styleClass, etc.

RE: selectionlistener for tree2
Posted by Mihir Solanki <mi...@patni.com>.
Sean,
Suppose I extend HtmlTree class to customize the tree2 behavior, how can I
tell My Faces so that it takes my extended tree component and not the
HtmlTree?
Please guide me regarding what kind of entries I need to make in which
files...
And as far as action listeners are concerned for the navigation (plus,
minus) icons in tree, I am fine if I can get the same functionality by
extending the tree2 component.
Thanks
Mihir Solanki

I don't think its accurate to say that tree2 does not support
actionListeners. If you look at the simple example there are all over
the place. It is probably more accurate to say that tree2 does not
support an actionListener for the navigation icons.
There are a few reasons for this and I would be interested in a way to
address this limitation as long as the approach is straightforward and
(most importantly) would work in a variety of cases not just a few
specific cases.
One major issue with this is that with client-side toggle the events
would have to be queued up through javascript somehow and then
communicated to the server when it was time. Its not impossible but
it would add complexity for limited benefit (in the client-side case.)
I could see this being more useful in the server-side case where
there is too much data to populate at once. I'm interested in seeing
Rob's subclass and JSP code when he is done to see if there isn't a
way to incorporate this into tree2.

RE: selectionlistener for tree2
Posted by Mihir Solanki <mi...@patni.com>.
Yes I am getting action events from h:commandLinks.
Could you please give me rough idea how I can sub class the tree2 component
and put an action listener for "+" and "-" images also?

Subject: RE: selectionlistener for tree2
Sean,
I have created tree2 and as per this email thread, I am getting action
events in my bean whenever I click on either "images" or "description text".
But the only problem is when I click on "+" or "-" images I and not getting
the action events as these images are (I guess) put bye the tree2
component...
So how do I get action events on "+" and"-" images for the consistence
behavior...
Thanks

It looks like your problem is that you have the method name as
processEvent in your actionListener attribute but you've defined the
method name as processAction.
If you want the tree to keep track of your selected nodes for you then
you *must* use:
actionListener="#{t.setNodeSelected}"
But if you want to handle things yourself, then there is nothing wrong
with what you are trying to do.
