Question

I have two portlets: Portlet-A and Portlet-B.

Portlet-A make some data initialization and stores this in shared scope.

Portlet-B during initialization requires this data (from Portlet-A) from shared scope.

However, I need to define that Portlet-A has to be started (rendered) before the Portlet-B.

Is it possible by Liferay to define some order of initialization, or something like portlet dependency?

Answer 1

If I understand correctly, you require Portlet-A to be rendered before Portlet-B on the same page.

Then you can define this in the liferay-portlet.xml: <render-weight>50</render-weight> the more the render-weight the more quickly the portlet will render or in other words if the render-weight of Portlet-B is less than Portlet-A then it will render after Portlet-A.

More explanation regarding render-weight in the DTD

Hope this helps.
