Re: [Wicket-user] Using Javascript Effects Before An Ajax Call
We've ended up using jquery (http://jquery.com) for all of our projects here and it provides queueing very elegantly.$('#myElementId').hide('slow').show('slow');It might be worth looking into integrating.

Re: [Wicket-user] Using Javascript Effects Before An Ajax Call
I think the best approach to this would be to add _javascript_ before the ajax call and add additional _javascript_ in the ajax callback function. This is a little tricky but can be done. Pausing the request on the server is definitely no the way to go.
I haven't looked at what _javascript_ is generated but your function for your effect needs to block so the ajax request doesn't execute until it's finished... This is usually best accomplished through callbacks.
function myFx(element, callback) { if (element.pixelHeight > 0) { element.height = element.pixelHeight - 5; setTimeout(function(){myFx(element, callback)}, 150); } else { callback();
}}function doAjax() { ajaxRequest... function: response(){ ... callMyFxFunction(); ... } ...}Content to be loaded by ajax when clicked
That's a very crude example (code is not tested), but shows most all of the concepts.-jsOn 11/15/06, Igor Vaynberg <

Re: [Wicket-user] Using Javascript Effects Before An Ajax Call
Thanks for the clarification Igor. I ended up achieving the desired affect by using an AjaxCallDecarator in combination with a server side pause. Basically I was trying to do the following: 1) Run animation effect on element 2) Use Ajax request to replace element 3) Run another animation effect on the element As you noticed, I needed a way to block so that #2 and #3 would not step on #1. As a non-Javascript guru I was unable to find a way to block the Javascript "thread" without some kind of CPU beating hack loop. However, the solution I am using seems to work well.

Re: [Wicket-user] Using Javascript Effects Before An Ajax Call
why would this be a bug in wicket? looks to be clearly a bug in your code. the effect is clearly executed asynchronously from the rest of the _javascript_ "thread" so you need to find a way to block until the effect is complete.
