Variable Filter not recognizing Path Variables

[mwiegand]

Hi,

the Varaible Filter node is not recognizing and therefore passing through varaibles of the type Path.

Not quite a bug, more a gap but when trying to isolate issues:

Call Workflow throws NullPointerException

Hi, ocassionally, when rewiring preceeding nodes, the call workflow node throws a NullPointerException. WARN Path to String 3:1706 The selected column 'Path' has the wrong type ERROR Container Input (Variable) 8:1224 Caught "NullPointerException": Cannot invoke "org.knime.core.data.IDataRepository.addFileStoreHandler(org.knime.core.data.filestore.internal.IWriteFileStoreHandler)" because "dataRepository" is null ERROR Call Workflow (Table Based) 3:1699 Execute failed: Failur…

Definately a hinderance.

@mwiegand Just to confirm my understanding: does this happen only when there are two flow variables with the same name but different types (String and Path)?

I am curious how you managed to get both variables with the same name at the same time, since in my tests, one usually overwrites the other.

Hi @k10shetty1,

thanks for your feedback. I used the Create Temp Folder in conjunction with a path to string variable node. Did I miss adding that in the test workflow?

Create Temp Folder

PS: The workflow is the same as in the other post I guess.

Unfortunately, I am unable to replicate the situation where two variables have the same name.
