Subject [PORTAL] Launch Parameters
Date Wed, 13 Dec 2006 17:45:02 GMT
Hello everyone,

I'm looking at supporting "launch parameters" for the Portal in 
Trinidad.  To recap my understanding of them, in the TrinidadFilter, 
Trinidad does its filter stuff and then does a doFilter on the 
FilterChain.  When the chain returns, the TrinidadFilter checks for the 
existence of LaunchParameters and, if they exist, it essentially 
executes the doFilter again with a modified set of parameters (and thus 
runs the Lifecycle again).

In Portlets we really don't have this capability because this is really 
controlled by the bridge right now and it is unlikely we'll be able to 
support this without specific enhancements to the Bridge until JSR-286.  
So my question is, would I be able to "simulate" this behavior in a 
portal environment by sending a redirect back to the portlet with the 
new parameters?  I know that this will cause performance issues in the 
short term, but it will do so only in a Portal environment and then only 
until filters are supported in a portal environment.

I'm simply not sure how these are used, exactly, which is why I'm asking 
if the redirect would be functionally equivalent.
