Rest connection does not allow multiple same values



A REST request with the same parameter but multiple values must be sent.

Error Messages

Not Applicable

Steps to Reproduce

Create a REST connection, and attempt any one of the approaches given below.
  • Approach 1: Define multiple parameters of same name. Only the last one gets assembled in the URL.
  • Approach 2: Try and pass comma separated values on single parameter. The comma gets converted.
  • Approach 3: Try and add value for parameter plus additional name or value pairs using & or =. The & and = gets converted.

Root Cause

A defect in Pegasystems’ code or rules.
In Pega 7.1.9, pyInvokeRestConnector calls pxDereferenceEndpoint activity to get raw URL, which is then copied into mainURLBuilder local variable for processing. This is the root cause for the issue Approach 1. The current process results in adding only the last parameter.

In Approaches 2 and 3, the activity pxDeferenceEndpoint passes strings to StringUtil.cleanURL, which causes the unwanted character conversions.
