Queries with text value constraints are not working correctly

Zero patients are always returned when the query contains a value constraint for a text (enumerated) value. The problem is the single quotes are missing from the xml message that is sent to the CRC.

Example of current xml for <constrain_by_value>:

<constrain_by_value>
       <value_type>TEXT</value_type>
       <value_constraint>(ADEQUATE)</value_constraint>
       <value_operator>IN</value_operator>
</constrain_by_value>


In the above example you will notice the single quotes are missing around the value of ADEQUATE.


Here is what the same xml should look like:

<constrain_by_value>
       <value_type>TEXT</value_type>
       <value_constraint>('ADEQUATE')</value_constraint>
       <value_operator>IN</value_operator>
</constrain_by_value>


NOTE: This is only an issue in the webclient. Queries with text value constraints are working correctly in the workbench (eclipse client).
