iReport 3.5.2 does not like string initial values

[prosvet]

Since this morning, for a new report (Groovy or not) it gives the following error message when trying to preview:

"The initial value class is not compatible with the variable's class"

Simplifying the report, I came to the simplest case to reproduce: variable is a simple java.lang.String to be able to put a label inside. The error comes even for one variable, not placed on the repoirt layout. Report is empty. (cf. attachment)

Any idea?

Apparently, when I add manually variable's initial value in the jrxml file (cf. code) or modify an existing (pre-3.5.2 created jrxml file) variable's initial value, everything is OK.

However, when I create the variable in iReport and type in initial value, the error appears. So, for the moment, I have to create all my labels with iReport, position them, and then add initial values manually in jrxml file. Feasible, but cumbersome.

Code:

  <initialValueExpression><![CDATA["test"]]></initialValueExpression>
