there is a situation. I want to adapt the options in NodeDialog according to input port object. In a scenario, if I choose the option in Dialog, then it gives me available attributes of event log; after choosing attribute, it lists all possible values for this attribute. It needs the interaction with input data.
My questions are:
- is it possible to read input port object in NodeModel/configuration() method?
But in configuration method, there is only the PortSpec.
- How it works that option parts in NodeDialog in advance knows columns names from one DataTable before NodeModel/execute()? Is it all based on the columnSpec??
