pipeline @param.output usage

[kcpevey]

This is a little strangeness. I'm not sure if this is anticipated behavior. If so, then it should be documented.

this works (passes the anticipated owi_obj):

@param.output(owi_obj=winds.OWI)
def output(self):  
        return self.execute()

This doesn't work (passes owi_obj as None):

@param.output(owi_obj=winds.OWI)
def owi_obj(self):  
        return self.execute()

And this doesn't work (passes owi_obj as None):

@param.output()
def owi_obj(self):  
        return self.execute()

[philippjfr]

@param.output(owi_obj=winds.OWI)

Could you briefly explain what winds.OWI is? Is it a type?

[kcpevey]

winds.OWI is the class, owi_obj is an instantiated instance of that class (hope I got that language correct)

[kcpevey]

that class is defined in es_workflows/winds.py. I dont think you'll need it, but just in case.

[philippjfr]

Okay makes sense, thanks. Could you do me one more favor and provide the output of:

class.param.outputs()

on the class where this output is declared.

[kcpevey]

I switched to panel master. All of my original statements are still valid and I also discovered that this works (passes the correct owi_obj):

    @param.output(owi_obj=winds.OWI)
    def foo(self):  
        return self.execute()

Shouldn't this be the same as the following, and if so, does that work?
