Re: Calling javascript after asynchronous update
Would this also be the reason that I can't get an AjaxDirectLink to
behave correctly if it was in an updated component? Unfortunately I am
on Tap 4.0, so my fix may be more difficult if this is the case.

I think someone mentioned that something like this now should work.
A workaround is to have the script you want to execute already in the
template and conditionally render it

Hi
I'm using Tapestry 4.1.3.
I'm trying unsuccessfully to invoke some javascript after an
asyncrhonous update. I'll post code if needed, but here is the
summary:
1. Simple page with a list.
2. Initialization javascript makes list sortable using
script.aculo.us: Sortable.create('cityList', {only:'sortable',
onUpdate: onCityListReordered });
3. I have an EventListener that fires when the list is reordered
4. The list is asynchronously updated.
So far so good.
The problem is that after the update, the list items are no longer
draggable. I'm assuming that this is because the replacement list
needs
to be re-initialized via Sortable.create. If this is right then I need
to invoke some javascript after the update.
I try adding the javascript from the event listener method:
@EventListener( targets = { "cityList" }, events = { "onUpdate" } )
public void onItemsReordered(IRequestCycle cycle) {
//updates
cycle.getResponseBuilder().addInitializationScript(this,
"...inline
javascript...");
}
This causes a NullPointerException because the DojoAjaxResponseBuilder
has a null PageRenderSupportImpl (_prs).
Am I approaching this the right way? Any pointers appreciated.

Re: Calling javascript after asynchronous update
Thanks, Andreas.
The workaround works for me. I'll let you know how the snapshot turns out.
