Hi all,
for the application I'm working on I need a tree component which is more
configurable/capable than the current Struts2 s:tree component.
Basically I want to use it like this:
<t:tree rootNode="%{rootNode}" typeProperty="type"
childCollectionPropert="children">
<t:treeNode type="group">
<s:property value="%{name}" />
</t:treeNode>
<t:treeNode type="item">
<s:a><s:property value="%{name}" /></s:a>
</t:treeNode>
</t:tree>
Depending on the type of the current node one of the two childNodes
should be rendered in the tree structure.
This is similair to the MyFaces tree2 component.
I looked at the implementation of several struts2 components/tags,
started to write my own tag, etc.
Btw, writing struts2 tags is really hard, imho. Almost no documentation
in the code, no tutorials and books about it.
I don't know how to render the content of the chosen contained treeNodes
on demand. I just see a way to repeatedly render the whole body of the tree.
How would you write such a component? How could I solve this?
Thanks a lot for any hints!
Joachim
