Problem with newCase(xml) inside expression of master entity

Hello!

I have create an new Expression for the action of an stakeholder context, which is added to an master entity.

I will create inside the expression a new Case with the CHelper function newCase(<xml>).

But the parser for the expressions get an error with my xml.

Then i will use the content of the case where the expression is called via button click and copy them in a new case of the same master entity and process.

Short xml example:

1. var sXML = "<BizAgiWSParam>";

   sXML += "<domain>" + Credential.Domain + "</domain>";

   sXML += "<userName>" + Credential.UserName + "</userName>";

   sXML += "<Cases><Case><Process>RegisterCustomer</Process>";

   sXML += "<Entities>";

   sXML += "<Customer>";

   sXML += "<Firstname>" + <Firstname> + "</Firstname>";

   sXML += "</Customer></Entities></Case></Cases></BizAgiWSParam>";^

   CHelper.NewCase(sXML);

The problem occur in this line:

1. sXML += "<Firstname>" + <Firstname> + "</Firstname>";

The error output can you see in the attached pic error.png.

What can i do to get my use case up and running?

Thx,

Andreas
