Got an exception during migration Web application from WAS 6.1 to WAS 7. This application developed using JSF1.1 (MyFaces) + Facelets + Spring (for backing beans). On some pages I’m getting the following exception: 

Caused by: javax.faces.FacesException: Could not retrieve value of component with path : {Component-Path : [Class: javax.faces.component.UIViewRoot,ViewId: /pages/recovery_accs.xhtml][Class: javax.faces.component.html.HtmlForm,Id: sequestration][Class: javax.faces.component.html.HtmlDataTable,Id: _id37][Class: javax.faces.component.UIColumn,Id: _id50][Class: javax.faces.component.html.HtmlOutputText,Id: _id52]}

Tried to use different version of facelet library and different EL implementations. Even tried to recompile project using IBM’s JDK. Still no success. On Apache Tomcat it works without problem.

In a stacktrace above – IdocAccBean is a regular java bean which extends an abstract class IdocAccCore. If I use other backing beans which extend that class I get the same exception. All other beans not derived from IdocAccCore work correctly. There is nothing special in IdocAccCore class and it’s pretty big so I don’t think it’s necessary to give full source code.

Any suggestions what can be wrong with that IdocAccCore class?

    The problem solved by updating IBMs version of JRE. Actually, I was thinking that I’m using the latest version of IBMs JRE. For sure I downloaded one from IBM’s siteIBM Development Package for Eclipse. The problem is that this package contains pretty old version of IBM’s java 1.6. Fresh version of IBM’s java I found in fixpacks for Websphere AS.
    You can find detailed list of fixed bugs in IBM’s java 1.6 here
