When using the Row Edit Dialog and adding a new row, if the first field in the dialog is Required, then the validation automatically triggers for this field when the Row Edit Dialog first loads. I would not expect this validation to trigger without the user doing anything. It should only trigger if the user goes to the next row without entering information.
Here is a jsfiddle for this issue: http://jsfiddle.net/ru5Rk/3/
Just hit 'Add a New Row', you will notice that the First Name field validates right away as soon as the dialog opens. I would not expect this to happen. This does not occur when using the regular Row Edit (non-dialog) mode.
Paul,
The fix for development issue 172873 is in the latest service release and you can download this from the My Keys and Downloads page.
Let us know if we may be of further assistance.
Hello Paul,
I have investigated your issue and, I have asked our engineering staff to examine this further. To ensure that it will receive attention, I have logged this behavior in our internal tracking system with a Development ID of 172873. The next step will be for a developer to review my investigation and confirm my findings or to offer a fix, or other resolution.
I will leave this case open and update you with any new information after the review. You can also continue to send updates to this case at any time.
As a workaround you can change the position of the required field(not to be on the first place).
Please let me know if you need more information.
