Connected user node to variadic port does not trigger dependent nodes preview updates

Deyan

Hi,

I have several user nodes declared in a custom user nodespace, very similar to the example.nodes project in the SDK examples.
Unfortunately I encountered a problem while declaring a node with variadic input attribute, that has a portbundle as data type. The exact problem I notice is that the previews of dependent nodes of the one with the variadic input are not updated when any connected nodes to the variadic portbundles are changed. As a detail here - I noticed this only happens if the connected nodes (as inputs) to the variadic portbundles are also user nodes and having the builtin Color or Value nodes used as inputs properly triggers preview updates.

So from the above description I think I'm missing something in the declarations of my user nodes, that leads to this behavior. Can you assist me in what might be wrong in the user nodes setup or in the definition of the nodespace?

Thanks in advance,
Deyan

Upon some further investigation and testing I found this is reproducible only on R21, S22 and R23.
Is this a known issue that has been fixed for S24, and is there a workaround for earlier versions?

Hi,

Sorry for the delay, I'm asking the devs and that could take longer than usually.

Hi,

would it be possible that you share with us the code and the database to reproduce the issue?
We got some tools to see behind the curtain that could help to tell what's going wrong.

Hi,

Could you be more specific what parts of the code are necessary - only the node space declaration, the preview image provider implementation or something else additionally?

Hi,

you created a bundle GUI? or are you just creating user nodes with the resource editor?

If you created the bundle GUI, i would need the nodespace declaration, the database declaration, the database itself to have the user nodes.

Is this doable without too much work?

Hi,

I'm just creating the portbundles from the resource editor, without a custom bundle GUI.
So I guess you only need the database? I'll try to minimize the database to include only the necessary nodes and portbundle declarations and email it to [email protected]

Cheers,

Hoo sorry i thought you have implemented everything, so in that case, yes only the database should be enough.

Hi,

This question has been answered by email. You can use the DescriptionProcessors to build/rebuild the wires inside the Usernode.
