Nice tip Scott, thx.
I have a question for you though, and this more just to get some ideas
going in my head. I'm just wondering what your main use case for this
type of scenario is?
If you were putting the div tag below in one portlet only to pull
content from another, why wouldn't you just call the second portlet in
the first place? I am sure you have your reasons, and that is why I
am curious. I am betting you are using AJAX in combination with your
portlets in a pretty cool way...
To this point, my main use cases for AJAX (and dojo for that matter)
has been to:
1. Dynamically populate HTML form elements (eg. select options) based
on selections in previous HTML elements.
2. On-demand triggering of time-consuming tasks on the server
asynchronously so that the client does not block while waiting for it
to terminate (eg. running a report).
For the second one, I may pull down HTML mark-up or it may come in the
form of XML data , I haven't decided yet. For the first, it will
definitely be XML based. So I suppose my use cases thus far have been
more data/service oriented, but I am interested in expanding my use of
this technology...
thx,
aaron
