Hi, I guess I have a very simple question, since i am very new to python.

On a wrangle I created an ordered menu.

the Menu Python Script looks like that:




I read from a detail string array called "wall_ids" and the menu gets created as expected. All items from the string array appear in the drop down menu.

But when I try to simply access the chosen string value from the created parm with something like :


I get a -1 as a value instead of the actual string value.


Could somebody help me out here?

Does anyone have an idea why the access to the string value does not work?

Hi,

Could be how you are accessing the current node. I would just do it like this:

make sure you wall_id attribute don't already exist as a different type, the fact you say your value is '-1' tell me that this attribute already exist in your network, since a badly configured chs() should simply return an empty string.

Not sure but it could be a bug. I remember facing the same issue some time ago since then I use string parms as menus to pass string values.

Thanks for your replies!

I tried


instead of


this didn't seem to change anything. The dropdown menu works, just like before. Meaning the string values from the array are listed as expected.

Also I made sure the the attribute didn't exist in the first place.

But still, when I try to access the parm with vex from the wrangle, I get a -1 as a result.

Thank you! By using string parms, it works!
