Subject: RE: may MarkupContext in UpdateResponse contain no elements.
this was also my point when we had this no markupString and no markupBinary
discussion.
The bottom line was it is allowed. Mike's argument was (as far as I
remember, Mike please correct me) that since no markup is being returned
there is no mimeType.
Howerver on the Consumer side you need to handle this because you need to
diplay something in the portlet markup area. We currently display an empty
String ("") which is allowed for html.
Otherwise we would need to display an error message. But on the other hand
we said that such a return is valid.
Should we revisit this topic on the next interop call? (For clarification)
Mit freundlichen Gruessen / best regards,

Need to check this tomorrow but it seems I'm trying to set a null
perferredTitle! [A bit like Bob Geldorf who got a knighthood for his
live-aid work but can't be called "Sir Bob" because he is Irish. Mind you,
he is known as "Saint" Bob in Ireland.] Thanks for catching this one.
However, I would think the markup==null=="" rule only applies when a
mimeType is included in the returned markupContext (if it applies to
performBlockingAction at all ;- we only considered getMarkup() which should
be returning markup).
regards,
Andre

Andre,
when testing the Citric producer I noticed that when I click on the action
link and invoke performBlockingInteraction() with "cloneBeforeWrite" set,
the citrix producer returns a new portletContext and a new MarkupContext.
However the MarkupContext contains no elements at all.
We check if MarkupContext is being returned and cache it so we don't need
to call getMarkup here.
But since there is no content finally nothing is displayed.
I think from the specs point of view if MarkupContext is returned it has to
contain some data:
1. usedCachedMarkup should be there (if the producer want to refer to the
consumers cache contents)
1a. if useCachedMarkup is not set, the default is set to "false"
2. in case of useCachedMarkup=false, either markupString or markupBinary
have to appear.
2a. we agreed that one could interpret the spec that there is simply an
"empty Markup" if none of markupString or markupBinary appears. In this
case the consumer displays an empty markup.
So here we interpret the MarkupContext the citrix producer returns as an
"empty markup" returned and therefor do not call getMarkup() after
performBlockingInteraction().
Here is the message:
