I guess that you initialize source or columns in pageBeginRender and they are null until then. Since the Direct listeners are invoked before pageBeginRender, Table gets the nulls and you get the described exception.
Could you make getSource()/getColumns() to initialize lazily instead? (initialize if saved value is null, otherwise just return it) That should resolve this problem.

Hi,
I'm receiving an ApplicationRuntimeException whenever I attempt to sort a Table component. The initial load of the Table component is fine, but any attempts to sort cause the ApplicationRuntimeException with this message:
"Either the tableModel parameter or both source and columns parameters must be specified by component CompPlannerHome/directReports.directReportsTable.tableView"
The offending Table component is embedded in a custom tab component that I am building. So long as the Table was directly embedded in a Page, I have not had a problem. I can't seem to sort out what the difference is.
I have attempted to step through the debugger to sort out what is going on. Here's a synopsis of what I've seen. Hopefully someone can shed some light.
After clicking the column header to trigger the sort, I stepped through the listener cycle. Throughout the listener cycle, the TableModel is non-null and available. After the listener cycle, during the render cycle on my custom tab component, it is null. In fact, none of the bindings for my custom tab component have been set yet. I'm not really sure why this is.
As I mentioned, it works fine on the initial request. Requests to change the sort seem to causes the problem.
Also, the call to pageBeginRender on my custom tab component that happens just prior to the renderComponent on the Table is able to see/access the table model for the contained Table component.
Here's a stack trace. I hope someone can help. I've been struggling with this for two days....
