hello,

no idea ?? it's impossible to use modalPanel if it take a lot of time to appear..
the problem occurs after migration to the last 3.2.2 snapshot..
event the content of the modalPanel is empty it takes more than 10s to be shown..

here the code that call the modalPanel inside dataTable..

<a4j:support event="onRowDblClick" reRender="details" action="#{queryBean.getSelected}" oncomplete="javascript:Richfaces.showModalPanel('_panel',{left:'auto', top:'auto'})" />

Could you provide some example for compare? Feel free to create an issue. Then attach war and tell us for example that it will be one second under 3.x.x and 20-50 sec under 3.2.1. Then we will investigate this ASAP ;)

thanks ilya;

tested on 3.2.1 CR4 and 3.2.2 snapshot, it takes 14s for both..
it is normal??
modalPanel on demo site appear very quickly..but I use a4j:support inside dataTable and not simple link..

[ilya_shaikovsky]

So, maybe most of the time lost while server interaction?

[lmk]

I test on local machine..server interaction is faster for other requests, even display filter or sort a dataTable with 1000 rows..
test with no action.just

<a4j:support event="onRowDblClick" reRender="details" oncomplete="javascript:Richfaces.showModalPanel('_panel',{left:'auto', top:'auto'})" />

NB: use of myfaces 1.2.2 facelets 1.1.14.

We recently found a performance issue with ModalPanel that was caused by slow javascript - it's still unresolved for us. Maybe these are the same?

yes it seems similar, IE7 dont suggest to stop javascript execution, on FireFox it works better.

I can now specify the cases of the problem.

when i display all rows of dataTable more than 500 rows, modalPanel makes long time..

it works better if dataTable rows are not enormous.

regards!

Also having this problem; really slow on a page with a semi large table.

Would it be possible to add a property to the component telling it if it should disable the background elements or not.

Would be nice to just have it popup a dialog super quickly without having to worry about the background stuff (assuming this is what thakes time/cpu).

Cheers,
Micke

lmk, try to add ajaxSingle=true to your support.
