NullPointerException on clicking Work list widget header to sort
SA-101933
Summary
The user has configured a customized portal (Save As of Manager portal). On clicking the header of the Worklist widget on the portal dashboard to sort or move to the next page in the Worklist widget, the System administrator error window displays.
Error Messages
java.lang.NullPointerException
Steps to Reproduce
- Open the Manager portal.
- Click any header in the worklist widget.
Root Cause
The D_Workbasket DataPage was referred as the source in multiple grids. As the data page was enabled with the 'Limit to a single data page' checkbox on the Load Management Tab, each new reference to the data page created a data page instance that overwrote the existing instance and caused the issue. The 'Limit to a single data page' checkbox was to prevent the creation of multiple instances of the data page on the Clipboard.
Resolution
Perform the following local-change:
Uncheck the 'Limit to single data page' option from the Load Management tab of the out-of-the-box 'D_WorkBasket' data page.
