Re: Portlet question

Hi,

Yes it's possible

From:

http://www.jahia.org/jahia/webdav/site/jahia_org/shared/documentation/WebAppGuideDRAFT1.pdf

"
The contextid is a String that is useful to have an identifier to
separate different instances of the same application. Jahia
allows the same application to be instantiated multiple times on
the same page. *The contextID will be an identifier that will
change among these instances*, so that instance specific data
may be stored in the application. In the current implementations
of Jahia, the contextID is equivalent to the fieldID that
contains the application.
"
And 2 fields (even if in same page) have differents fielID...


In order to have contexID value:
String contextId = (String) 
request.getAttribute("org.portletapi.contextid");

You have to add in ALL your database tables a column (eg. CONTEXT_ID) in 
order to filter by context id.

Exemple:
select * from Project became select * from Project as p where 
p.context_ID = contextID.

Cheers,
Khaled.
