apply fix to TemplateAction to im 4.0?

[sergiocontrino]

in release 4.0 a bug has been introduced and commit c1bd944
in dev fixes it.
it has been fixed for flymine in production, and the 'one of' constraint seems to be working fine there after the fix.

Take a look at this template, the one-of constraints do not work,

http://www.flymine.org/flymine/template.do?name=modENCODE_RNA_seq_Tissues

If you click on edit, the constraints do not render properly:

    <constraint path="Gene.rnaSeqResults.stage" code="A" editable="true" op="ONE OF">
      <value>[Ljava.lang.String;@253b011
      </value>
    </constraint>
    <constraint path="Gene.rnaSeqResults.expressionLevel" code="B" editable="true" op="ONE OF">
      <value>[Ljava.lang.String;@4724dd95
      </value>
    </constraint>

@sergiocontrino can you describe the bug that you fixed? What was the bad behaviour?

[julie-sullivan]

See #2044

[sergiocontrino]

the fix is in commit c1bd944, where the condition
String extraValue = extraValues == null ? null : extraValues[0];

has been substituted by the verbose

String extraValue; if (extraValues == null) { extraValue = ""; } else { extraValue = extraValues[0]; }

extravalues being null was giving en error.

This is working in beta flymine.
