Hi Jamie,
Thanks.
I found error in /IWFND/ERROR_LOG.
The custom field is empty in error log, so custom field don't allow null.
I fixed to allow null about cutom field in SEGW.
Then I've solve thie issue, but next issue has occurred.
When I access custom App in Sandbox with Tomcat,
screen returns to its original in Sandbox list page.
I couldn't find error in /IWFND/ERROR_LOG
1.Select Cutom App
2.Opportunity list are displayed only during the moment
3.The screen returns to original screen.
My extension project is to add two custom filed about date & status.
What should I do in order to test the application?
Regards,
Yuki
