updating lots of components breaks


I’m having some problems where updating lots of components in firefox,
it becomes slow and it renders white blocks on the screen.
My screen has about 35 text fields and 143 native select spread over 5 tables.

I was able to create a very simple maven application which demonstrates the problem:
http://dias-project.co.za/adhoc/dias/vaadin-progress-dialog-0.0.1-SNAPSHOT.war (this link was wrong, its correct now)
bzr co lp:~amanica/+junk/vaadin-progress-dialog

When you click the button it starts adding components.
on my computer (64bit kubuntu)
at 20 firefox’s ajax starts acting up: white blocks starts appearing between updates
at 12 chromium’s javascript times out

Any help or tips to analyze this more would be appreciated.

After some time with no reply on this, I checked back and realized that the sample app url was wrong.
I fixed that now.
I understand that one does not want too many uicomponents on one screen, but in real life its difficult to avoid.
Is there anything that can be done about this?

Hi Marius,

i experienced same issue with firefox 3.6.9. It works without visual errors on Chrome 6.0.4 and Safari 5.0.1.

Youre using the CssLayout which is, please correct me when i am wrong, the most lightweight layout allready.
