Hello,
I have an TIWCGJQMenuItem on a form that is linked to an action on a datamodule.
I have changed the action's visible property, but the menu item is still visible.
I thought it was an asyncRender thing, but calling mnuRight.AjaxReRender(True,False) did not help.
I then get the menu item using FindByMenuItemName and checked the visibility of the item. It was true, even though the visibility of the associated action was false.
I hope I am doing something wrong, and that you do support the standard behavior of using an action to change the visibility, enabled, etc of linked controls. I know that setting caption via the action seems to work.
