When you change the object type specified in the root template (which is the entry point of the Generator), this modification is not automatically taken into account in the associated UI project. This basically means that the pxDoc menu may not appear when right-clicking on an instance of this object.
To update the UI project accordingly, right-click on the .pxgen file (located just below the .pxdoc file) and select Run As -> Generate pxGen Artefacts.
