[jira] [Commented] (CAY-1786) javax.swing.table.DefaultTableModel
cannot be cast to org.apache.cayenne.modeler.editor.ObjAttributeTableModel
[ https://issues.apache.org/jira/browse/CAY-1786?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13544048#comment-13544048 ]
John Huss commented on CAY-1786:
--------------------------------
What do you think about adding some functionality to automatically relay errors to a central server so that we have a better handle on Modeler issues that arise? I know I run across problems occasionally, but I don't often take the time to save the stack trace or dig into it.

> This was first described in comments to CAY-1727... While CAY-1727 is fixed, the ClassCastException remains, so it is a separate issue. It doesn't happen on every model, but it does happen on a few that I have (and that I can't publicly share) pretty consistently. It goes something like this (but I am not 100% sure of the scenario) :
> 1. Open a project
> 2. Navigate to any ObjEntity, select its "attributes" tab
> 3. CLick on DataMap
> 4. Click back on any ObjEntity.
