Steven Katz updated WICKET-2178:
--------------------------------
Description:
Source that replicates the problem is attached. Extract with 'tar xvzf
treeproblem.tgz'
The example works fine with wicket 1.3.4
The page displays a Tree Component
1) Expand the top node of the tree
2) Select the first child node (or any node really)
3) Press the Delete link

I investigated this down through the source and the problem seem related to a
change made to AbstractTree (the one in wicket not wicket-extensions)
Please see my comments on this nabble thread (reproduced below):
http://www.nabble.com/Illegal-State-Exception-on-DefaultTeeModel.removeNodeFromParent-td20185042.html#a22547387
I have the same problem using 1.3.5, but not when using 1.3.3. I spent some
time tracing the source code and it seems related to the addition of this line:
getTreeState().selectNode((TreeNode)item.getModelObject(), false);
at the very end of the function (line 835):
AbstractTree.treeNodesRemoved()
This line results (eventually) in a call to
AbstractTree.invalidateNode()
which on line 1295 calls:
item.remove()
which alters the state of "item" such that the call to item.remove() in
AbstractTree.treeNodesRemoved() fails with the exception mentioned previously.
I note that the IItemCallback() code, immediately above, calls two identical
lines in the reverse order. I wonder reversing the later two would fix the
problem?
was:
Source that replicates the problem is attached. Extract with 'tar xvcf
treeproblem.tgz'
The example works fine with wicket 1.3.4

2) Select the first child node (or any node really)
3) Press the Delete link

> I investigated this down through the source and the problem seem related to a
> change made to AbstractTree (the one in wicket not wicket-extensions)
> Please see my comments on this nabble thread (reproduced below):
> http://www.nabble.com/Illegal-State-Exception-on-DefaultTeeModel.removeNodeFromParent-td20185042.html#a22547387
> I have the same problem using 1.3.5, but not when using 1.3.3. I spent some
> time tracing the source code and it seems related to the addition of this
> line:
> getTreeState().selectNode((TreeNode)item.getModelObject(), false);
> at the very end of the function (line 835):
> AbstractTree.treeNodesRemoved()
> This line results (eventually) in a call to
> AbstractTree.invalidateNode()
> which on line 1295 calls:
> item.remove()
> which alters the state of "item" such that the call to item.remove() in
> AbstractTree.treeNodesRemoved() fails with the exception mentioned previously.
> I note that the IItemCallback() code, immediately above, calls two identical
> lines in the reverse order. I wonder reversing the later two would fix the
> problem?
