SageCRM 7.3 Custom gadget of type list based on a custom report using custom view. Loads first page without error but the next page (and last page) buttons result in perpetual ""loading"" cursor and error message ""an error occurred when attempting to process the gadget"".
The report runs to completion under the reports menu, and change the default display number of records in the gadget from 10 to 20 does not change the behavior. I am not seeing a related error in the today's logs.
Tomcat log has this, which appears to me to indicate success:
