> When list variables are declared with a list containing variables as initial value, the managing VariableListExpression seems to save the variable expression given with that argument list instead of the represented values. E.g.
> {code:java}
> INTLIST somelist = {var};{code}
> for a variable
> {code:java}
> INT var = 1;
> {code}
> stores the expression behind var instead of the value 1. So changing the value of var after the declaration of somelist still effects the value of somelist[0]. That's not the case if ADD was used instead.
> Consider this example:
> {code:java}
> DECLARE testType (StringArray arr);
> STRING s = "a";
> STRINGLIST sl = {s};
> Document{ -> ADD(sl, s), s = "b", CREATE(testType, "arr" = sl)};{code}
