Datagrid - Deleting a newly created row

[swader]

When I add a new row to my datagrid with the detailview helper, the values are populated properly because I call "reload" immediately afterwards. But the new row, as an object, has only one value: Object { isNewRecord=true}. Now, when I punch delete, it tells me it can't find the given index,

Code:

data.rows[_49f] is undefined
[Break On This Error] 	

_3ca(_4a2,opts.idField,data.rows[_49f][opts.idField]);

Now, if I refresh, this row is ok and can be deleted. But I can't delete it IMMEDIATELY after creating it, and I would like to.

If you define the 'idField' property, every records should have a key field. Add key field to your added record or remove the 'idField' property from datagrid.

Removing the idField from datagrid worked, thanks!
What does that option do, anyway? I couldn't figure it out from the documentation.

The idField indicate the key field, it is not necessary. If the idField is set, the selected records will be remembered while navigating records through multi page.

Interesting, thank you! That might come in handy later on.
