How to Refetch a listGridField filter editor optionDataSource

[tprokuski]

I have a few fields(ListGridFields) tied to optionDataSources and displayed in a ListGrid. I need to refetch these values when in filterEditor mode and an external action occurs. How can I accomplish this? What I need to accomplish is similar to refreshing the displayed data in a Formitem tied to a datasource. For that I am able to use the following code:

((SelectItem) itemFilterForm.getItem("item_id")).fetchData();

I need to accomplish this same behavior on a ListGridField in the filtereditor for the desired fields.

Solution to refresh

from the forums we tried this solution which worked:

associateSearchGrid.setShowFilterEditor(false);
associateSearchGrid.setShowFilterEditor(true);
