Tapestry Using Ajax
Hi I'm using ajax and javascript to automatically update a select box when
any one of the other select boxes on the page update. Up until now it has
been working fine but I now have a problem that it wont let me debug mt
tapestry page that it is being used on? It just continuously loads and the
page never fully loads.
Has anybody encountered this or know's how to fix it?
Also a side note how do you get rid of the flashing when the page is being
updated using javascript?
Cheers.

In order to prevent the yellow fade, set update in zone component to
'show'(you have not shared the zone so I don't know if you have set that or
not) as illustrated in

I am calling several different event methods? Would that be the cause?

I have been trying to get my code working without the yellow fade but with
no success thus far. My previous code was:
public Object onChangeOfKeeper() {
keeper = _request.getParameter("param");
if (keeper == null) {
captains = null;
}
else if (keeper != null) {
captains.add(keeper);
}
return _searchZone.getBody();
}
I have now changed it to this but no updating is happening:
public Object onActionFromGoalkeeper() {
//keeper = _request.getParameter("param");
if (keeper == null) {
captains = null;
}
else if (keeper != null) {
captains.add(keeper);
}
return _searchZone.getBody();
}
Any ideas?
Cheers

If page is not loading fully, it might be a because of recursive ajax calls
