[#2526] - Var change saving report

Dear Mr, our company has detected a bug in your iReport editor software. I'm attaching an example with the mistake for your test.

If you use a var type "double" in any place in the report, later, if you save it, the var will be changed to String type, and we will get a error in the compilation.

If later, in properties we change the opcion from java.lang.String to java.lang.Double, saving the report, closing it and re-opening it the has been changed again to String.

Thank you.
