ListGridField fetchMissionValues

I have a ListGridField with a optionDatasource.
My problem is that this ListGridField sometimes have values that are not present in the picklist fetched from the optionDatasource.

FetchMissingValues requests are only sent when I actually enter the editor for the field, and the values are not saved to the displayMap so when I exit the editor it goes back to showing the underlying value.

I cant figure out how to distinguish between a fetch request for the displayMap and one for the picklist. It that even possible?

I guess I want to somehow return all the display values in the initial fetch (from ListGrid.autoFetchDisplayMap) and only a subset of the values when fetching for the picklidt.

I hope it makes sense, otherwise let me know and I will try to explain it better.

Read the docs for listGridField.optionDataSource - the suggestion is to deliver the display values in the main set of Records loaded into the grid (those shown as rows), as a separate attribute.

When saving, the record returned from the update or add operation should have an updated displayField value as well, thus updating the grid without the need for a separate cache.

Okay I see.

So if I use this method I am not supposed to set an optionDatasource on the field. So do I just set the picklist data via a manual fetch to the "old" optionDatasource and setValueMap?

You should set optionDataSource via editorProperties or editorType as normal. Since listGridField.optionDataSource has not been set, this won't cause a full-DataSource fetch, and the editor will automatically pick up the current displayField value from the Record when editing starts.
