IPC

Hi,

For IPC we can use

1. PublicRenderParameter -- In Liferay the way Tag-cloud and blog communicates each other.

2. Events.

In these 2 options which one we can prefer.

What are the advantages and disadvantages?

[Kamesh Sampath, modifié il y a 10 années.]

I would prefer to use "Events" the very simple reason being it can transfer any serializable objects wherein PublicRenderParameter is always String.

Also, with public render paramter portal remembers them for all later executions of the portlet until the portlet is invoked with different parameters.

So using Events is the recommended way with jsr286

Hi,
The choice is dependent of your requirements. With public render parameter you can pass only String parameter while with Events you can pass any things between portlets.
