When configuring data generation using a list, if we use multiple strings, each having comma separated values, it working fine. But if we combine the values using the Multi-Select List in the dropdown, TDM Portal is treating whole string as input and then treating each comma as a delimiter and creating the string array out of that. Also, when creating a variable using the Multi-Select List dropdown, and defining the List Definition so that it contains a list of comma separated list of variables. For example, @aslist(@list(~var1, ~var2, ~var3)@)@. When validating in Data Painter, the returned string doesn't contain any commas, and is seen as a single string.
This issue is resolved in TDM Portal 5.0.15.0.
