Integration APEX 4.0 and CDM RuleFrame

Richard Teunissen — Thu, 17 Nov 2011 06:48:46 +0000

For a client of me, the Ministry of Defence of Kingdom of The Netherlands I have developed a solution to use CDM RuleFrame with APEX. They are using CDM RuleFrame 6.5, Apex 4.0 and the framework ‘ApexLib’. If CDM RuleFrame is used and one or more business rules are violated on the APEX’s Error Page an error message will be shown that is very cryptic to the end user. This is something we should try to avoid as much as possible. In this article I give some insights on how to give more user friendly error messages in combination with CDM Ruleframe, Apex 4.0 and the 'ApexLib' Framework

User locked, error message ‘invalid logon credentials’.
