Answer Value does not support special character



Answer values assigned to a radio type Complex question does not support special characters.

A question is saved with answer values containing special characters and used in the Question Page (QP) assignment. On selecting an option with special characters in the answer value, a refresh occurs and clears the selected option.

Error Messages

Not Applicable.

Steps to Reproduce

  1. Create Complex radio matrix question.
  2. Provide Answer values with special character (for example, 'Frequently used 50%'. The '%' is a special character).
  3. Use this in the Question Page that is displayed to the user as part of the Survey
  4. Select an option with a special character value.

Root Cause

A defect in Pegasystems’ code or rules :

A Complex radio control (RadioButtonComplexQuestionSurvey) does not allow special characters due to a mismatch between strAnswer and strValue in the Control logic.


In the RadioButtonComplexQuestionSurvey control, modify the below line of code,

String strAnswer=myPage.getString(".pyAnswer");


String strAnswer=StringUtils.crossScriptingFilter(myPage.getString(".pyAnswer"));

Alternatively, update to Pega Platform 8.2.3.
