Divide an Ajax request into two parts
Hi All,
Suppose i have a textfield with and oncomponentchange behavior which is
being used to do a search.
Now the search can be done in two ways, say 1 method is faster than the
other.
The searrch results are displayed vide ajax in a table.
Is there anyway to fire two consecutive ajax requests?
So when the textfield is updated, first the search is done using method 1,
the results table is updated.
If the textfield is updated further within a certain interval then the cycle
restarts.
If the textfield is not updated, a second ajax request is made after an
interval. This does the search using method 2, and the new results are
appended to the table at the end of the results for search 1.
The advantage of using this method is that 95% of the time the search will
yield results using search method 1 so hence it should not be slowed down by
having to do both the searches and then joining the two sets and displaying
the results together.
Thanks.

Yeah, that sounds like a synchronization headache....
i guess another way of phrasing this is whether there is anyway of making an
AjaxUpdate non-blocking.
as data is available, it will constantly update.
Be very useful for searches

Use OnChangeAjaxBehavior to fire request to method 1 and
AbstractAjaxTimerBehavior for method 2.
Override their #getChannel() method to return different name so they
are not queued at the client.
Have fun with synchronizing them...
