Hello:
This error is random under Desktop Pipeline and seems to have something
to do with page order (document-order) and submit action. Everything
worked fine under portal pipeline.
I have two tabs (yes, two psml page). I have four or five portlets on
each page. Also, on each page, I have a portlet contains a submit
button. The problem is, most of the time, only the portlet on the first
page works (i.e. after click submit, all portlets finally renders with
contents). When I navigated to the second tab (page), I tried to submit
something, all other portlets except the one with submit button,
rendered well with content inside. The portlet with submit button
displayed a null pointer error inside it.
I am attaching the log below, but hold on, even strange...
When I switch the document-order of those two pages (folder.metadata),
all two pages worked fine.
To make things even mysterious, I deployed a second portlet application
and created the third page which contains portlets from the new app. One
of those portlets was an action portlet. Same problem happened. The
behavior seemed to be: the first. The action portlet on the last page
usually caused a null pointer exception.
Here is the exception:
