Current Revision posted to Appian Knowledge Base by Parmida Borhani on 7/23/2018 3:44:07 AM

Symptoms

The following errors are seen when using a!recordLink() to generate a URL for a record:

ERROR:An error occurred while evaluating expression: =rule![RULE_NAME] (Could not find variable 'env!clientMode') (Data Inputs)

Expression evaluation error in rule 'RULE_NAME' at function a!recordLink: Could not find variable 'env!clientMode'

Cause

SAIL functions like a!recordLink() return internal system data types. Parsing the fields of the returned system data type in an expression causes the error described in this article and is not supported because they often change between versions and hotfixes.

Action

Use the OOTB functionality included with urlforrecord() instead of building a link by parsing the output of a!recordLink().

Affected Versions

This article applies to all versions of Appian.

Symptoms

ERROR:An error occurred while evaluating expression: =rule![RULE_NAME] (Could not find variable 'env!clientMode') (Data Inputs)

Expression evaluation error in rule 'RULE_NAME' at function a!recordLink: Could not find variable 'env!clientMode'

Cause

SAIL functions like a!recordLink() return data types. This error occurs when fields from SAIL functions that return data types are used in expressions. Parsing internal CDTs like this is not a supported implementation, because they often change between versions and hotfixes.

How to generate a link to a site record

Parmida Borhani — Tue, 25 Jul 2017 01:03:36 GMT

Revision 1 posted to Appian Knowledge Base by Parmida Borhani on 7/25/2017 1:03:36 AM

The OOTB feature, urlforrecord() function, should be used to create record links instead of the a!recordLink() function. Parsing the a!recordlink() function and using the CDT fields to generate a link to a site record is an unsupported design and should be replaced with urlforrecord(). Generally, fields from SAIL functions that return data types should not be used in expressions, because they often change between versions and hotfixes.
