I use SD4.5 with SP19. I'm trying to insert subforms when the template is changed in work orders. I' ve succeeded to do that with the category field. Let me write what i did;
1 - I created generic relations with template and form field. I setup the related relations with the template field values and subforms. 2 - In the form i put the insertion marker. 3 - In the UI rule I control the change on template field, if any change exists on the template field i insert the subform.
That' s all good working with the category fiedl. I' m able to insert the right subforms and clear when needed dynamically. But when i try to use template field i can not play with subforms. Thanks in advance.
