I would like to have a property that, if left blank.. gets a default value. Im thinking it wont work.

in a python node 

FLD="DEFAULT"

FN="{{^FolderName^}}"
if FN is not None:
     FLD=FN

 

it breaks at setting FN="{{^FolderName^}}"

No value was able to be evaluated... Any way around this?

It not horrible if I cant, just a convenience..

  If you put an = after the parameter name but still inside the brackets it will take that value as the default when the parameter has not been given any value.

  e.g.

  FN="{{^FolderName=MyDefaultValue^}}"

  A couple of things. I noticed yesterday you had an extra ^ in the parameter value (3 rather than 2). I think with 3 it will only take the default value so make sure it is like this (no quotes also):

  {{^FolderName=+FLD+^}}

  Another thing I have noticed if you enter a parameter value you seem to have to hit Enter on your keyboard to make it stick. If in doubt refresh the browser page too. I'm going to test my theory on having to hit enter and raise as a potential bug if it seems appropriate. Have a look at the screenshots attached.

  Sorry Gerry! I just noticed my mistake, deleted that post lol  (yes I did catch the other ^ too)

  I was setting FN, but the code following was using FLD so it was never picking up the FN value :) lol

  soooo ignore me.. I need more coffee!

   

  THANK YOU!
