If you set the value of a pin via the plugininterface, and the pin information didnt exist in the patch xml, that value is not being saved.
E.g: The Tag pin of an IOBox is not automatically filled and created in the patch XML when you create that node. Now if you set the Tag pin value via the Plugininterface, for example the Pinserver (not via SetPatch), the value is set correctly. It even shows up in the patch xml you get through getPatch. But when you save that patch, the information is lost. You have to create the field first either manually or via setPatch to be able to save the data that is held in there.
This one is based on the Server (vvvv) helppatch.
Instead of writing to the value field, it writes to the Tag pin.
The value written there is not being saved, unless you set the Tag field manually once.
But if you getPatch on the Patch in which you changed the Pin Values only, the Values still do appear in the PatchXML description. This is misleading then.
And as we know setting PinValues via SetPatch was possible before, just much slower …
