Process an event of a node changed after removing the node cause an Exception
-----------------------------------------------------------------------------
Key: TOMAHAWK-206
URL: http://issues.apache.org/jira/browse/TOMAHAWK-206
Project: MyFaces Tomahawk
Type: Bug
Components: Tree Table
Versions: 1.1.1
Reporter: Josué Burgos
Priority: Minor
I think this is a bug but I'm not sure. When processing a node changed event
after removing the node in the tree model cause this exception:
java.lang.ArrayIndexOutOfBoundsException: -1
at java.util.ArrayList.get(ArrayList.java:326)
at
javax.faces.component._ComponentChildrenList.get(_ComponentChildrenList.java:42)
at org.apache.myfaces.custom.tree.HtmlTree.findNode(HtmlTree.java:550)

org.apache.myfaces.custom.tree.HtmlTree.treeNodesChanged(HtmlTree.java:761)

org.apache.myfaces.renderkit.RendererUtils.renderChild(RendererUtils.java:441)
It doesn't find the node because it is removed before processing the event.
Perhaps I have to force processign the events before removing the node but I
don't think so.
A fix to the problem could be:
549 int index = translatedPath[i];
550 if (index == -1) return null;
551 node = (HtmlTreeNode) node.getChildren().get(index);
instead of:
549 int index = translatedPath[i];
550 node = (HtmlTreeNode) node.getChildren().get(index);
or capture the IndexOutOfBoundException and return null.
in HtmlTree.java
