SelectItem setValueMap does not refresh

Hi

I have a application with a DynamicForm a DataSourceTextField and SelectItem as the textfields EditorType.

I insert the picklist-values for the selectItem via setValueMap with a LinkedHashMap. Everything works fine, except that if I want to change the pickliste-values by recalling setValueMap (with a different map), the values don’t get updated.

Any suggestions?

Thanks
