Metanode extension using wrapped meta nodes

Node Development
1

Hi

I've created a meta node I'd like to make available in the node repository. I appear to be able add a normal meta node succesfulyl but not a wrapped meta node.

I get the following error with the wrapped meta node: 

WARN  WrappedNode Input    1:6:68     No subnode container set 

Has this not been implemented yet or am I doing something wrong?

Cheers

Hi,

 

I have the same problem,

 

When I add my subnode in the folder of metanode in plugin.xml :

   <extension
         point="org.knime.workbench.repository.metanode">
      <PersistedMetaNode
            category-path="/MyRepo/InPutOutPut"
            expert-flag="false"
            id="org.knime.nodeTest.Reader_Quest"
            name="Reader"
            workflowDir="metanode/wrap/Reader_Quest">
      </PersistedMetaNode>
   </extension>

I have this message :

WARN  WrappedNode Input    0:17:1     No subnode container set

And my subnode becomes like a simple metanode

Yes, correct. Not implemented/supported.

We have an open feature request to link the wrapped metanodes in the repository (once supported) with the instance that the user puts into his workflow. So whenever the 'master' in the node repository changes (= code/bundle gets updated) it would allow the user to refesh his instance).

Thanks Bernd.

Hi Bernd,

are there news on that topic? Is there a time window when wrapped metanodes may go into an repository?

Best,
Armin.

Sort of. Very soon the hub will support sharing components publicly and they can be used to achieve this.

Thanks for sharing this. This looks very promising.
Although, I think, the search functionality needs some advanced features to narrow search results down

Any ideas how ideally the search would work for you to narrow it down? Could you give examples, e.g. first I would like to do this, then that etc…
