Bug in iReport 3.5.3 Datasource Provider

[foyasing]

Hi,

I think there is a bug in iReport 3.5.3 for Datasource Provider.

I created my own datasource provider implementing JRDataSourceProvider and JRDataSource interface.

In iReport, when I click: 
Edit query -> Datasource Provider tab -> Get Fields From Datasource button
Everything is ok up until here, it lists all the fields.
But after I click OK and return to main page, the fields are not saved, they are gone.

 

My code works fine on iReport 3.0.0, no problem there, iReport can retrieve the fields

Thanks
Arie
