Undefined Message Dialog Box When Clicking Button

Hi – I get a dialog box saying “Undefined” when I click on a button … Any idea how I can troubleshoot this? I don't think the debugger will work on a button

Thanks for the all the feedback – culprit was a CustomString widget that was taking a context/entity parameter and simply concatenating multiple string attributes. Weird it errored on a listview when it works fine on a dataview, but I removed it and will display the text some other way.
