Unable to clone input data at port 1 (In-Port name): No value present

Hi, i have created a custom port object that export a model on the output port. When i receive this port object as input, it seems that the #savePortObject and #loadPortObject methods of the port object serializer aren't called.

It's possible the port object's clone problem is this? How can i solve it?

Have you registered the serializer in the extension point?

No, how can i do this?

Thank you.

In your plugin.xml for the project with the code for the port go to the extensions tab

You then need to add org.knime.core.PortType

Then create a new portType in this extension point and fill in the Extension point elements



It's done.

Thank you very very very much!!
