I am having this problem when i am attempting to use several Porlets on a Portal page in a local Websphere Portal Server, the main porlet uses an event triggered by a link to submit an ID to the others Portlets, after receiving this events the "children" portlets will refresh showing related data to ID captured.
This scenario works fine when i'm using only the "parent" portlet and a single "children", when i attempt to include a second "children" into the page, a full page refresh its performed instead of partial page as its implemented in the "children".
It doesn't seem to be related to a particular children since it happens after combining different children, single entity tests was made and never a full page refresh was made.
The inter portlet communication is made using an event triggered by the parent and received by the childrens.
I have several questions related to this events trigger and handlers.
Can only be associated an event handler for event ? Can i send an event that trigger a response in multiple "children" portlets or its limited as a single parent - unique child relation?
Any suggestion is appreciated.
