Issue/Introduction

Description:

Trying to assign a value to a linked field. Getting error:

Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed. Common causes for this error are when the response is modified by calls to Response.Write(), response filters, HttpModules, or server trace is enabled.

Solution:

View the form being referenced in the url, for example frmAsset.aspx. Find the form under the inetpub folder in the Web Server.

Make a backup copy of the file.

Open the file in Notepad.

There should be a line similar to:

 	<%@ page language="vb" autoeventwireup="false" inherits="CA.Presentation.Web.Interfaces.Argis.frmAsset, 
 	Argis_WebDeployment" 	enableEventValidation="false" 

 	viewStateEncryptionMode="Never" %> 

Add the ValidateRequest parameter to the end:

 	<%@ page language="vb" autoeventwireup="false" inherits="CA.Presentation.Web.Interfaces.Argis.frmAsset, 
   Argis_WebDeployment" 	enableEventValidation="false" 

 	viewStateEncryptionMode="Never" ValidateRequest="false" %> 

Reset IIS and the UAPM Cache Service and retest the issue.
