Orbeon 3.9 Liferay proxy portlet java.lang.NullPoi

Question

I'm trying to integrate Orbeon Forms 3.91 PE with Liferay 6.0.6. I have installed Liferay, deployed orbeon.war, orbeon-proxy-portlet.war, copied the license file and created a file-local.xml properties (as described in the wiki).

Using the Form Builder I've created a form (the default content (one input field)).

Next I've added two pages in Liferay containing the portlets forms: - one runner with my form - second form refers to a form "contact" (the default one).

After integration with my form (eg try to save form) I'm getting error:

ERROR ProcessorService  - Exception at line 55, column 65 of oxf:/ops/xforms/xforms-server.xpl (reading processor output: name='response', id='xforms-response')

It looks like AJAX bug and the problem sessions managing.

After moving to form "contact" and interact with it I get the error:

Since that time, this error also appears on my form (first one).

How can I fix it? (both forms from localhost: 8080/orbeon work properly).

Answer 1

The proxy portlet is unfortunately broken in 3.9.1. Since that release we have implemented many fixes and improvements to the portlet, and the proxy portlet should work well with Orbeon Forms 4.0 M7.
