Oh, sorry for the self reply, but I forgot to address the editing /
not showing up issue.
Try using undefined instead of empty string. The DataGrid replaces
undefined with single space (which can be a headache if you try and
cast to a number to return to your persistence layer ... don't get me
started ...). It's probably no different then just using a single
space, but I feel better about it on a purely emotional level :-)
The line is gridAddRow would then be:
for (var i = 0; i < aCols.length; i++) { newRow[aCols[i]] = undefined; }
