Browser Out of Memory on TreeGrid refreshes

[JLivermore]

SmartClient Version: SC_SNAPSHOT-2011-01-06/PowerEdition Deployment (built 2011-01-06)

Windows XP

IE9, FF17

I have a TreeGrid that refreshes on a Timer, when there is no data during the refresh, memory seems to be stable. When there is data in the TreeGrid, upon every refresh memory with the browser(s) steadily grow until an Out Of Memory browser error is shown.

It appears the TreeGrid is holding on to the data after every refresh? Any thoughts as to what I can check or do code wise?

Upon further testing, it appears IE9 has a memory issue, memory keeps growing when there's data being returned in the TreeGrid. FF17 appears to have a steady memory footprint and does not grow when there's data being returned in the TreeGrid.

Any experience with IE10?

IE9 broke the JavaScript eval() function, causing it to always leak memory (details here). All provided workarounds do not actually work, so we had to make extensive changes to the system to get around IE's incredible blunder here.

This was done for 3.x and 4.x only and won't be done for 2.x (too risky and pre-dates IE9). So you'll need to upgrade.

Is this an issue with IE8 on the version we are on?

No, this breakage happened in IE9.

Ok, thank you.
