How do you get Tree2 expandAll to work?
The example throws an exception. My code does not throw an exception but it
does not fully expand the tree either.
Here is what I tried:
public String myOrgExpandAll() {
myOrgTreeComponent.expandAll();
return null;
}
The above works when the tree first loads but if the user expands any tree
nodes, it stops working.
I also tried this:
public String myOrgExpandAll() {
this.myOrgTreeComponent.getDataModel().getTreeState().setSelected("0");
myOrgTreeComponent.expandAll();
return null;
}
This works better in that an expand always happens, but it is not recursive.
Instead of an expandAll functionality, it becomes the functionality of
expand the root node and then display children in whatever state they happen
to be in. We are replacing an existing application that has a working client
tree. This needs to work for us.
We looked at the example code. We are doing the same thing. We looked at the
test cases (Junit test), we are doing the same thing.
Do you guys have any thoughts on how to get this to work?
Here is the code:

import org.apache.myfaces.custom.tree2.HtmlTree;
import org.apache.myfaces.custom.tree2.TreeState;
import org.apache.myfaces.custom.tree2.TreeStateBase;
