Re: [wsrp] Coordination and frames

Yes, frames have there own set of issues.

Solutions depend on the complexity one
is willing to implement on each side.

I would guess the simplest is having
a wrapper within each frame which implements an onload handler to walk
the markup tree and update appropriate target attributes to reflect what
the server (which will process any URL activations) expects. Other more
complicated scenarios could involve having the returned wrapper include
which other portlets now have stale content so that refresh action can
be triggered against them.

[wsrp] Coordination and frames

In investigating solutions to handle the nested form
issue we discussed 

at the F2F I have been looking into using frames instead of form 

rewriting as a potential solution.  This has lead me down the track
of 

trying to figure out how our coordination could work when a page is 

rendered as a set of frames.  The basic problem relates to our 

assumption that coordination is scoped for a set of portlets [a page] 

yet few portlets assume they are rendered in frames hence don't 

manage/set the link/form targets in their markup yielding the default of

"self".  I.e. the typical portlet's link and form refs will
result in 

the browser filling this portlet's frame with whatever content is 

returned; for correctness this must be a link/form reference that only

renders the referenced portlet. 

So how does coordination work in this environment?  Public parameters

and events are designed to interact with other portlets on the page 

resulting in these other portlets also needing to render.  But as
said 

above, we typically in a conetxt to rerender/receive these additional 

renders.  Ideas?
