Class ErrorHelperBean

java.lang.Object
org.imixs.workflow.office.util.ErrorHelperBean
@Named @RequestScoped public class ErrorHelperBean extends Object
CDI Bean for handling and extracting meaningful error information from servlet exceptions.

This bean provides utilities for JSF error pages to display user-friendly error messages and detailed debugging information. It automatically traverses exception chains to find the most relevant error messages, prioritizing business exceptions over technical wrapper exceptions.

Usage in JSF pages: 

 <h:outputText value="#{errorHelperBean.rootCauseMessage}" />
 <h:outputText value="#{errorHelperBean.fullStackTrace}" />

Example Exception Chain Handling: 

 ObserverException
   └─ Caused by: SomeWrapperException  
       └─ Caused by: ModelException: "Invalid expression: #{!controller.method()}"
 
 Result: Returns "Invalid expression: #{!controller.method()}" as the root cause message
