Convert a column of a list of entity to a comma separated string...

0

Hi,

I have a “List of <TagEntity>” which has a column “Name” and I need to pass this list to a REST call, for that i have to create a comma separated string of this list.

e.g. List of TagEntity (stored in a Variable, fetched by “Retrieve Objects” Action):

Name

======

“Input”

“Output”

“Power”

“Test”

==> I need to convert this rows to a string for my REST-Call ==>  ‘["Input", "Output", "Power", "Test"]’

Is there a function to do this? or how can i perform this…

hope someone can help me with this issue (I am new to Mendix).

regards,

Andreas

Ok, i got it! It can be done with a “Loop”.

Fetch list from database; Create an empty String variable; Loop; Add Iterator-Item to string; ...
