FormItem validation bug ([Error in echoLeaf: TypeError: ...)

[Blama]

Hi Isomorphic,
please see attached test case (v10.0p_2015-08-24/PowerEdition Deployment).

If I change the SKU and click "Validate & Save", I get the following request (attachment) in the Developer Console (note the "Error in echoLeaf").
I don't know why this is happening. The setup resembles my application setup. I'm using FormItem.validate() because of another bug with ValuesManager.validate() (report follows if I can replicate the behavior in builtInDS).

Please add this to the SKU-field definition in .ds.xml (needed in order to trigger a serverside validation):

<validators><validator type="isUnique" errorMessage="SKU already in use!" /></validators>

Best regards
Blama

Just a quick note to let you know we are looking into this.
We are reproducing the problem, and the good news is that it appears to be something you can safely ignore - it looks like an issue with logging only.

We're looking at how best to fix it and we'll follow up when we have a fix.

This issue should now be fixed. Please try the next nightly build (Oct 6 or above)
