Minor 1.0.1 => 1.0.3 migration issue

[Andy Malakov]

Hello All,

I recently migrated from OJB 1.0.1 to 1.0.3 and found one minor regression.

It looks like custom FieldConversions no longer supported for ojbConcreteClass 
fields. I have several classes mapped to the same table, and I use tag stored 
as CHAR(1) DB column to identify concrete class (my custom FieldConversion maps 
between class names and tag values). Using conversions for ojbConcreteClass 
wasn't actually documented, but worked fine in 1.0.1 :-)

It seems that adding conversion to RowReaderDefaultImpl (1.0.3) solves the 
problem:

    protected String extractOjbConcreteClass(ClassDescriptor cld, ResultSet rs)
        ...
        String result = (String) fld.getJdbcType().getObjectFromColumn(rs, 
fld.getColumnName());
+      result = (String) fld.getFieldConversion().sqlToJava(result); // <= 
ADDED LINE
        if (result == null || result.trim().length() == 0)
            ...


All the Best,
Andy
