----------------------------------
Summary: TableTree#updateNode() fails if no corresponding node is
visible
Key: WICKET-6235
URL: https://issues.apache.org/jira/browse/WICKET-6235
Project: Wicket
Issue Type: Bug
Components: wicket-extensions
Affects Versions: 6.24.0, 7.4.0, 8.0.0-M1
Reporter: Sven Meier
Assignee: Sven Meier
TableTree#updateNode() tries to locate the corresponding node by visiting all
Item children. If this node is not visible currently (e.g. because a parental
node is collapsed), the children visitor runs into the table header (which
comes after the table body) - causing a ClassCastException when the Item is
expected to have a NodeModel, which it doesn't inside the header (or footer).
