RE: abort loading lazy components
Hi,
It seems that probably WICKET-4227 is not fixed. I am still getting problems in 1.5.5.
If I override ajax channel like:
@Override
protected AjaxChannel getChannel() {
return new AjaxChannel( "0", AjaxChannel.Type.DROP );
}
Only last item is loaded and other items are in continuous loading state - see WICKET-4397.
With unique channel name:
@Override
protected AjaxChannel getChannel() {
return new AjaxChannel( String.valueOf( System.currentTimeMillis() ), AjaxChannel.Type.DROP );
}
lazy items are loaded asynchronously, however if I try to do action which results in drop, I am getting the same exception as in Wicket-4227.
Best regards,
Michal Wegrzyn

RE: abort loading lazy components
Posted by Michal Wegrzyn <mi...@onior.com>.
Hi Martin,
Thanks for the response. I thought that simple change in existing quickstart is better than completely new quickstart, but if it is more comfortable then no problem :)
Created https://issues.apache.org/jira/browse/WICKET-4470
Maybe WICKET-4397 can be already closed then, as WICKET-4470 describes everything.
Best regards,
Michal Wegrzyn

Re: abort loading lazy components
Posted by Martin Grigorov <mg...@apache.org>.
Hi Michal,
Last time I tried your quickstart it was working OK with 1.5-SNAPSHOT.
The problem is that you test with a different quickstart than the
attached one in the ticket.
First I made it working at 24 Nov, then you verified at 25 Nov, then I
re-verified at 25 Jan and then you said "yeah, but I changed few
things in the app locally and it breaks again".
Please create a new ticket with a failing quickstart. I want to run
the app and see the problem without any interventions from my side.
