PM82169: DO WHILE LOOP CONDITION EXECUTES TWICE IF MODIFYING TAG VALUE USING ECMA SCRIPT

Subscribe

You can track all active APARs for this component.

APAR status

  • Closed as program error.

Error description

  • When executing a Do While loop, the condition statement will
    execute twice if using ECMA script and the condition modifies
    the tag value used in evaluating the condition. ᄊ If there is
    something within the condition that is not a simple evaluation,
    it may change the outcome of the script.
    
    Example:
    tags["counter"]-=1;
    tags["counter"]>0;
    

Local fix

  • Move any statement inside of the condition that is not related
    to the evaluation to before or within the script.
    (tags["counter"]-=1; should be moved inside the script for the
    example provided in the error description)

    * PROBLEM DESCRIPTION:                                         *
    * Use of the Iterate-While action could lead to unexpected     *
    * results when the action condition contains ECMAScript. This  *
    * is because the action was being called once before the while *
    * loop first iterated. If the ECMAScript contained side        *
    * effects (such as decrementing the value in a tag) then the   *
    * user would not see the expected results as in the first      *
    * iteration the script would be called twice thus decrementing *
    * the tag by two rather than the expected one.                 *
    ****************************************************************
    * RECOMMENDATION:                                              *
    * Upgrade to Rational Integration Tester 8.5.0.2               *
