too much recursion error in 7.0beta

[senordhuff]

Hello,

We are seeing an intermittent too much recursion error. It has been diffcult to reproduce and the only place we have seen it so far is with 7.0beta in Firefox 3.

It also only seems to happen when Firefox has been left open for a long period of time. Below is some output we tried to use to debug. But, you can see clearly that 3 seconds of procEssing go by before Firefox quits and throws the too much recursion error at the end. This is simply a scenario where the user enters a search term into a Dynamic Form and clicks a "lookup" button which then loads a ListGrid below with the results. So, very simple interaction with no "extra" logic happening behind the scenes other than a simple custom validator. We'll keep trying to recreate but I' wondering if a "too much recursion" error could be the result of a browser that is simply suffering from a memory leak from being open too long and that is why we can't recreate?

[Isomorphic]

"Too much recursion" is very specifically about getting lost in an infinite loop, it doesn't seem likely to be caused by "browser fatigue" or anything similar.

I think the very latest versions of Firebug will actually allow you to drop into the Firebug debugger when this error occurs, so that's probably a good next step.
