Petportlet sample add Pet failing in Liferay 5.1.2

[peterox]

I have deployed the pet portlet sample application to Liferay 5.1.2 and everything was going great until I tried to add a Pet.

Throughout the 'add pet' code is the following line

response.setRenderParameter("action", "list");

The problem is that when this is run the portlet stays in 'Add Pet' mode.

I debugged the application and it seems that the render request has two 'action' parameters, both 'add' and the new 'list'.

Is this a Liferay problem or it there a better way to redirect to a different action than setting the 'action' parameter?

Can anyone help?

Cheers

It seems that this is a Liferay problem.

After a lot of hair pulling it seems that the problem is with the <render-weight> parameter in the liferay-portlet.xml deployment descriptor.

If it is set to 0 then the rendering of the portlet breaks.
