Bug in JRDataSourceProviders ?

[daniel.breitner32]

Hi everyone, I have implemented the JRDataSourceProvider Interface to deliver JRFields to my report. I am using this method:

 

public JRField[] getFields(JasperReport arg0)

[/code]

I want to create a dynamic JRDataSourceProvider and therefore I need the query language, that I can set in the "Dataset and Query ..." dialog.

 

Unfortunately I almost always get old data when I use

 

String language = arg0.getQuery().getLanguage();[/code]

 

to get the query language. It needs several refreshes and Project-> clean calls for me to get the correct query language.

Did I do something wrong ? Is there any other way to get the correct query language ?
