Xref ordering not working - producing problem after search

[antonak]

When you try to sort on an xref field and then try to search any field the records of the table do not appear any more.

The sorting on xref is producing this problem since I get an exception :

org.molgenis.framework.db.DatabaseException: Unknown column 'Biobank_Biodata' in 'order clause'

More specifically I tried to run the mysql query that produces this problem and found out that an extra join table is missing and the order field is not formed correctly :

e.g.

//SELECT Biobank.id, Biobank.canRead, ... xref_canRead.name AS canRead_name,... LEFT JOIN MolgenisRole AS xref_can... ORDER BY Biobank_Biodata ASC LIMIT 10 OFFSET 0

//SELECT Biobank.id, Biobank.canRead, ... xref_canRead.name AS canRead_name,... LEFT JOIN MolgenisRole AS xref_can... LEFT JOIN Biobank_Biodata ON Biobank.id = Biobank_Biodata.Biobank ORDER BY Biobank_Biodata.Biobank ASC LIMIT 10 OFFSET 0;

The second query works (added the red part). This is formed in AbstractJDBCMapper.java I am guessing by rewriteMrefRule? which here is abstract.
