Error description

• Map type UNKNOWN to String doesn't work in the Java Script case
  .
  Although using the same search alias for variables of different
  types is invalid/discouraged, a change is being made to lessen
  the problems exhibited with the javascript TWSearch API with
  this scenario.  The search variable is internally mapped to
  Unknown type due to the conflicting types,  so code is being
  added to map the returned value to String type when the results
  of the search are returned to the javascript layer.   Otherwise
  the values for that searchable variable are never returned.

Problem summary

• ****************************************************************
  * USERS AFFECTED:  Users utilizing Javascript API to create    *
  *                  saved searches.                             *
  ****************************************************************
  * PROBLEM DESCRIPTION: Defining two or more process            *
  *                      variables with identical search alias   *
  *                      values but of different type will       *
  *                      return with null value when queried.    *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  When creating saved searches using Javascript API, the queried
  results may return with null values if two or more variables
  are defined with the same search alias.  The issue can be
  seen when the variables of the same search alias are
  declared as different variable types. The existing saved
  search, which worked previously, will now return a value of
  null when executed.
  When executing this scenario, during runtime the low level
  engine code will return the variable as type UNKNOWN. The
  following may be seen in the trace logs with runtime tracing
  enabled:
  com.lombardisoftware.server.core.pse.impl.ProcessSearchQueryEngi
  ne prepareQuery propertyNames[....,
  businessData.problematicVariable3@Unknown,....]
  Javascript API code is unable to handle the UNKNOWN type and
  returns null.
  

Problem conclusion

• Code changes have been made to handle the duplicate search
  alias and properly return the correct value.  An interim fix
  is available on v7.5.1.1. The fix will be integrated into the
  next fix pack.
