Hi all,
i have a problem implementing filters to my datatable.
What i want is a filter reacting on changes in the filter textfields.
Let me call it 'live-filter'. So when you type, the table is filtered
via dataprovider.
I implemented the filter from the phonebook example, but this method
just reacts on form submit.
The next thing i tried is using a dataview instead of a datatable so i
can reach directly the filter textfields. Then i added a
AjaxOnUpdateBehavior to them, which submits the filterform via
'AjaxRequestTarget'.appendJavascript(document.formxy.submit();).
The problem resulting: too many database queries in too short
intervals. Sometimes he ignored letters from the textfield when you
type a little bit faster.
so i tried implementing java.util.Timer with a little delay. So my
thought was that you type sth and after the delay it begins to call
the database filtering with everything you typed so far.
But when i schedule a timertask, nothing ever happens. The interesting
thing is that logs from within the timertask's run() method are
displayed to the console.
It seems that only the formsubmit(appendjavascript) is ignored.
Could it be that it does nothing because of the extra thread started
for the Timer?
Do you know any solutions?
Or do you know any 'normal' and better ways to implement such a 'live'filter?
Thanks
Sascha
