The nodeView works fine when I executes the NodeModel directly. However, I get one exception with loading NodeView. It says
View instantiation failed: null
I track down the codes and find out the related parameters passed from NodeModel are null. Those parameters are :
Input PortObject 
Result OutputPortObject 
So my questions are, how to pass those parameters to NodeView?
- One possible solution could be to re-execute the NodeModel, and get refresh NodeView again. But how to trigger this re-excution while we already have the result in the stored workflow?
- Another solution is to get the
Input PortObject and OutputPortObjectin NodeView or NodeFactory, but how?
