Don\'t get custom FormatFactory to work by using JRParameter.REPORT_FORMAT_FACTORY parameter

[m_hammel]

Hi,

I'm woring with jasperreports 3.7.5

I'm trying to use a custom FormatFactoy implementation to handle the case of an empty string representation ( "" ) of the xml data for a date field. I implemented a class implementing FormatFactory which should handle that.

 

My jrxml looks like this

at my JRXMLDatsource I setted the source format patterns like this

and of course handing over a instance of my FormatFactory

Everything works fine here if the datasource xml do not contain "" values for a date field. But if that happens I got the exception

If I debug the method calls for my custom FormatFactory implementation I recognize that both methods are not being called until running on the exception. Thus I assume that jasper is using the default FormatFactory by any reason.

What do I wrong here? Do somebody have an idea about that?

Thanks in advance
