The edited row is disappeared from ListGrid if it has invalid data

SmartGWT 4.1p 2014-04-28
IE 11.0.9600.17041 (Update Versions: 11.0.7)

Using this sample below clicking Add for a new record. Do not enter values, and select another existing row. The newly created will disappear (but come back sometimes randomly)

Also in the case it appears, the validated line will be displayed with bigger font size.

Please let me know if you need anything else to repeat/fix. Thanks.

We're not reproducing this as you describe - in our testing if you enter no values and click another row, the edit fails, leaving the empty edit row visible with a validation-failure icon.

If you enter explicit values and click outside, or hit enter, things do go wrong - you end up with the data from the xml file being shown twice in the grid.
This is a result of the override to the dataURL, without a call to 'setClientOnly(true)' -- essentially the dataSource attempts to save the new record by sending a request to the server data URL, and is greeted with the (static) list of entries which it assumes have all be successfully added to the data set, and so updates the grid to show them all in addition to existing data.

In short - if you're trying to make a client-only dataSource, you'll need to mark it as such - if not, in order to support editing, you'll need a dataURL which can actually process the request and return an appropriate result for your edits.

(Also, as an aside, this dataSource has no primaryKey field, which is pretty much a requirement for editable dataSources, so records can be uniquely identified across edits).
