T5 questions: adding my own initializations; outputing pre-formatted HTML; tree component; javadoc
Hi,
I've recently started working with T5 because I liked a lot what I've
seen! I therefore have some basic questions, and I hope you can help
me with them:
1. I've started changing the quickstart project to move a current
struts2-spring-jdbc application to T5. Where can I put my dao
initialization (creation of hsqldb tables, which used to be done via
my ContextListener class in struts2)?
2. In my existing application, I use a (folder-like) tree based on the
www.dhtmlgoodies.com drag-drop-folder-tree. It is based on a standard
HTML unordered list, which I generate in my page's java class. In the
accompanying HTML file, I use "${formattedTree}" However, when I
return the formattedTree "<ul><li>..." it becomes <ul> etc. How
can I change the encoding, in other words, output raw HTML to the HTML
template file.
3. Related to Q2, are there any T5 tutorials on how to develop a tree
component, similar to a grid component? Or does someone already have
it?
4. Is it possible to enable T5 javadoc help to display in the Eclipse IDE?
Thanks for your help,
Erik

ho :) I didn't make the link between this page and you :)
I just opened a Jira issue to ask for the addition of a Tree element in
the code lib, so that every users may use the same base in place of
reinventing the wheel. Moreover, if the core developers are ok to add
such a component, we may hope that it will be more generic, idiomatic of
Tapestry 5, deeply tested, etc than ours. I post our two reference
implementations as examples.

Posted by Erik Vullings <er...@gmail.com>.
In the end, to create the Tree component (
http://wiki.apache.org/tapestry/Tapestry5TreeComponent) I've chosen to use
the writer.outputRaw option, since the opening/closing of the <ul> is very
tricky in the DHTML drag-n-drop-folder tree component. Clearly, it's less
elegant than the writer.element, so if anyone can improve it, please do :-)
The syntax of my tree is very similar to yours: I've only included an id, so
I can refer to it in the javascript (the DHTML tree adds an AJAX-based
context menu, which I.don't use yet though)
<t:Tree treeid='literal:demo' source="treeNodes" currentNode="node">
<t:actionlink t:id="tree"
context="node.identifier">${node.name}</t:actionlink>
</t:Tree>
I thought about using the java swing.tree object, but in the end, found it
more intuitive to explicitly set the depth of each node. Also because in the
sql db, I store the hierarchical elements using lft/rgt notation as
explained in
http://www.sitepoint.com/article/hierarchical-data-database/2
An example of the Tree component (image) can be found here:

I have an example tree component here :
http://svn.forge.objectweb.org/cgi-bin/viewcvs.cgi/interldap/interldap-wui-t5/trunk/src/main/java/org/interldap/wui/tapestry/components/Tree.java?view=markup&rev=97

Basically, the component take a DefaultMutableTreeNode as parameter and
print it in a preorder traversal.
You can specify a (unique) html element as a level separator. I think it
would be a good idea to clean the code and extend it in a more generic
way ;)
Hope it may help (and sorry for the delay, I missed your post)

Use the OutputRaw component.

You just need to have source attached to the jars you are using.

Hehe... I suppose if I'd read the old post more closely (as opposed to just
looking at #2) I could have figured that out. Sounds like the @EagerLoad
that Robin pointed to is what you want.

I don't follow how invoking an init method in your builder is related to the
problem of the html generation. Can you expand on that?
I would use a component and the MarkupWriter in the beginRender/afterRender
methods. Something like this: (this code has not been compiled so
compilation/functional defects may exist)
public class MyComponent {
void beginRender(MarkupWriter writer) {
writer.element("ul");
// if you have a tree then you could recursively build out the unordered
list...
for (String item : itemValues ) {
writer.element("li");
writer.write(item);
writer.end();
}
// you could end the element here, ending it in afterrender
// allows the component body to be evalutated.
}
void afterRender(MarkupWriter writer) {
writer.end();
}
}

I use an @EagerLoad service similar to this, example code can be found here:

I have the same requirement mentioned in #2. What is the best approach to
handle this with Tapestry 5? I am thinking of just eager loading a service
and invoking the init method in the builder method of the module. Any other
thoughts?
I think this was the Tapestry 4 way:
