Manual creation of user defined variables

[ashah12]

Hey development team,
I am trying to directly create a workspace for JDemetra using its Java libraries (e.g. jdplus-sa-base-workspace). I want to add Variables and userDefinedVariables.
When creating the Variables using the JD GUI, the variables show up in the XML file as dynamicTsVariable. One can add multiple of these to one item under Utilities > Variables and this shows as multiple variables in a single vars xml file.

I am trying to mimic this functionality using the addVariable function in the Ws class.

However, this creates one variable per file. It also creates static variables (tsVariable)- I can't see a way to create/add dynamic variables in the Ws class

Would you be able to guide me to better create Variables so that they all end up in one Vars xml file (perhaps mimicking the GUI process)? And could you explain the difference between static and dynamic variables?

Additionally would you be able to guide me as to how to connect the Variables with the appropriate user defined variable in each series?
Currently, I am adding a userDefinedVariable to the RegressionSpec class, with the name matching that of the Variable in the appropriate Vars.xml file:

But this is not producing valid workspace files and the JDemetra+ GUI doesn't appear to acknowledge the reference to the correct Variable.

Regarding the difference between static and dynamic variables, there is a short explanation at: https://jdemetra-new-documentation.netlify.app/a-outlier-detection#generating-external-regressors:
