Modal Panel preventFocus JS function slow
-----------------------------------------
Key: RF-3670
URL: http://jira.jboss.com/jira/browse/RF-3670
Project: RichFaces
Issue Type: Bug
Affects Versions: 3.1.5
Environment: Windows XP, Sun RI 1.2
Reporter: Tom Tamulewicz
Assigned To: Nick Belaevski
Fix For: Future
I have a page with a 500 row table. Each row has a "delete" link that brings
up a modal panel. The modal panel takes 4-5 seconds (with CPU spiked) to appear under
MSIE 6 or 7. The time it takes to show up is proportional to how many rows in the table.
If I have a small number, the modal panel shows quickly. The problem appears to be due to
slowness in the modalPanel.js preventFocus() function, which is called from the show()
function.
My test page wasn't very complicated, with a bean providing a list of 500 objects.
