Example how to use setOptionFilterContext()

[ectar]

I face the case when I need to filter optionalDataSource

Using criteria doesn't work here is the sample of code

ListGridField lf = lsf[i];
final ComboBoxItem cb = new ComboBoxItem();
	
	// this is very custom piece of code, works only when field name is "FIELD_NAME"
	if(lf.getName().equals("FIELD_NAME")) {
		cb.addClickHandler(new com.smartgwt.client.widgets.form.fields.events.ClickHandler() {
			public void onClick(com.smartgwt.client.widgets.form.fields.events.ClickEvent event) {
				Criteria fieldClit = new Criteria();
				String tableName = record.getAttributeAsString("TABLE_NAME");
				fieldClit.addCriteria("TABLE_NAME", tableName);
				cb.setOptionCriteria(fieldClit);									
			}
		});
	
	lf.setEditorType(cb);

Explanation of how setOptionFilterContext() forks is very vague
Is there a sample code where can I see how to use it on client and server sides.

Thank you
