[ http://issues.apache.org/jira/browse/TAPESTRY-1065?page=comments#action_12427972 ] Ryan Holmes commented on TAPESTRY-1065: ---------------------------------------
This bug only appears when showRootNode is set to false. > TreeDataView.renderComponent() and TreeTableDataView.generateNodeList() > cause ClassCastException in ITreeDataModel.getUniqueKey() > ---------------------------------------------------------------------------------------------------------------------------------- > > Key: TAPESTRY-1065 > URL: http://issues.apache.org/jira/browse/TAPESTRY-1065 > Project: Tapestry > Issue Type: Bug > Components: Contrib > Affects Versions: 4.0.2 > Environment: Tapestry 4.0.2 > Java 1.5 > Windows XP > Reporter: Ryan Holmes > > TreeDataView.renderComponent() calls ITreeDataModel.getUniqueKey() with a > root node object when it should be passing in a rootUID object (line 86 in > TreeDataView.java): > Object objChildUID = objTreeModel.getTreeDataModel() > .getUniqueKey(objChild, objRoot); > Instead of objRoot, objRootUID should be used, which has already been fetched > on line 62: > Object objRoot = objTreeDataModel.getRoot(); > Object objRootUID = objTreeDataModel.getUniqueKey(objRoot, null); > This causes a ClassCastException on line 80 of > SimpleTreeDataModel.getUniqueKey(): > TreePath objPath = (TreePath)objParentUniqueKey; > SimpleTreeDataModel implements ITreeDataModel correctly (which specifies that > a parent UID is to be passed into getUniqueKey() rather than a parent node), > and other callers to ITreeDataModel.getUniqueKey() pass in a parent UID, so I > believe this is a straightforward bug in TreeDataView and TreeTableDataView. > The same bug exists in TreeTableDataView.generateNodeList() on line 117: > Object objChildUID = > objTreeModel.getTreeDataModel().getUniqueKey( > objChild, > objRoot); -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://issues.apache.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
