Portlet Error " XForms error: Unable to retrieve XForms engine state from session cache."

Hi

I am running tomcat 6, with Orbeon Forms 3.51 with Liferay...

I have been developing my orbeon form / portlet today... and for some reason when its loading up the form I get this error

<form action="http://192.168.1.8:8181/web/guest/5?p_p_id=tiffinbites_contact_us_form_WAR_sampleorbeonformsportlet&amp;p_p_action=1&amp;p_p_state=normal&amp;p_p_mode=view&amp;p_p_col_id=column-1&amp;p_p_col_count=1&amp;_tiffinbites_contact_us_form_WAR_sampleorbeonformsportlet_oxf.path=%2Fxforms-server-submit" method="post" target="_blank" onsubmit="return window.confirm(&quot;You are submitting information to an external page.\nAre you sure?&quot;);"> Loading... XForms error: Unable to retrieve XForms engine state from session cache.

What do I need to do to debug the issue?

I will set the logging to debug and append it to my catalina.out and see what that brings!

But in the mean time, if you have come across the issue please let me know

Regards

Mark

Mark,

It could be that somehow your session expires or is otherwise not
enabled.

Do you ever NOT get it, e.g. if you load a simple Orbeon Forms
portlet, and then perform an action in the portlet (entering a value,
clicking a button), do you get the issue? Or does it only appear after
some time?

Note that this code has been almost entirely replaced in 3.6, with the
new persistent XForms state store.
