DynamicJasper AutoText字段中的参数？

Question

Given a report with a parameter, say foo with value bar , I'd expect the following to either print bar if it supported parameters, or $P{foo} if it only supported static text.

    AutoText showBatchAutoText = new AutoText("$P{foo}",
                                 AutoText.POSITION_HEADER,
                                 HorizontalBandAlignment.CENTER);

Instead it prints ((java.lang.String)parameter_foo.getValue()) , implying it does some kind of logic on the field...

Is it supposed to work? Am I misusing the "message" type AutoText?

DynamicJasper wraps the string in quotes before sending it to Jasper. So, sql injection attack style, you can bypass it with escaped quotes.

AutoText showBatchAutoText = new AutoText("\" + $P{foo} + \"",
                             AutoText.POSITION_HEADER,
                             HorizontalBandAlignment.CENTER);

A hack, but... it does the trick.
