Portlet Render Question if more than one Struts Portlet is involved - Loosing State
Hi,
maybe a little bit OT but maybe its struts related, don't know yet.
I've got two portlets written with struts2 2.0.11.2.
I've create a page and did both of them onto it.
Lets say Portlet 1 got "Step 1 and Step 2" and Portlet 2 too.
Pluto:
I click on the button to go to Step 2 of Portlet 1.
Result:
Portlet 1 is in Step 2.
Portlet 2 is still in initial Step 1 state.
Than i click on the button in Portlet 2 to go to Step 2.
Result:
Portlet 1 is still in Step 2 (good).
Portlet 2 is now in Step 2.
debug log show something like this:
18:50:01,904 DEBUG [org.apache.struts2.portlet.util.PortletUrlHelper]

The same stuff in Liferay:
I click on the button to go to Step 2 of Portlet 1.
Result:
Portlet 1 is in Step 2.
Portlet 2 is still in initial Step 1 state.
Than i click on the button in Portlet 2 to go to Step 2.
Result:
Portlet 1 is now again in initial State - Step 1 (BAD)
Portlet 2 is now in Step 2.
The log is different:

[org.apache.struts2.portlet.PortletRequestMap] Dumping request parameters:
The "Leaving Render" and "Entering Render" is gone @Liferay.
Whats the correct behaviour, i thought what pluto does is right, isn't it?
Does anyone know why this may happen, or does anyone have an idea why those
containers behave different and how it can be fixed?
thx

It's hard to say without seeing some code and configuration files. The
only difference I can think of is with the actualy deployment process
for each container. There are potentially several different
configuration files depending on the server you're deploying in. It's
a while since I've looked at Liferay, but could it be that the two
deployments refer to the same portlet instance or something? Or maybe,
since the rendering phase appears to have "gone", it's a caching
issue?
