Obj-Open-By-Handle Check if Lock exists
In an activity I have step 'Obj-Open-By-Handle' on a step page.
For the this method parameters I provided :
LockInfoPage (provided value LockInfoTemp1)
Now, the instance to be opened might already locked by the same user running this activity or others.
On the obj-open-by-handle step, I have jump condition so that when StepStatusFail is true it will go to a step that will print the values from LockInfoTemp1 page.
However, when I run the activity it terminates at the obj-open-by-handle call and registers in the pega log as:
"Exception java.lang.NullPointerException at com.pega.pegarules.data.internal.clipboard.ClipboardPageImpl.checkNamedPageForwardLinks(ClipboardPageImpl.java:5311) "
The tracer however shows 'Already Owned Lock'. This message is not available in the pega rules log.
Why is the obj-open-by-handle step exit the activity instead of being handled by the Jump statement?
Please find the attached screenshot.
Also, in some cases I noticed LockInfoTemp1 is not created or is empty. Is the lock info page only created when the check box Lock is enabled AND obj-open fails because of an existing lock?
If the 'Lock' checkbox is left unchecked, can we still open it if it's locked by another user? Does obj-open-by-handle succeed in this case?
Thanks Santanu. I enabled both StepStatusFail and exception in the jump condition. They both go to the same jump step where I am printing any page messages (@getMessagesAll(myStepPage) and also for the failure message from the transition step (pxThread.pxMethodStatus)
