Subject [jira] Commented: (TAPESTRY-2045) NoClassDefFound exception thrown when injecting DataTypeAnalyzer into a page
Date Tue, 15 Jan 2008 07:31:35 GMT

    [ https://issues.apache.org/jira/browse/TAPESTRY-2045?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12558948#action_12558948

Robert Zeigler commented on TAPESTRY-2045:
------------------------------------------

Very curious as to where you saw that exception. Because digging through my log files, all
I see are series of "NoClassDefFound" exceptions. 
Same goes for the sample project I submitted.  I get the following stack trace:
java.lang.RuntimeException: java.lang.ClassNotFoundException: caught an exception while obtaining
a class file for org.apache.tapestry.transformationtest.pages.Start

Even turning on debugging output, I don't see the exception message you posted.

>    Affects Versions: 5.0.8

> While attempting to upgrade my application from 5.0.6 to 5.0.7, I found several tests
broken (and the application broken, as well), with a "NoClassDefFound" error, whenever any
of the test pages (or application  pages) referenced a particular page.  The issue appears
to be a broken transformation when injecting the DataTypeAnalyzer service (possibly others?).
> I will attach a project with a single test case which illustrates the issue.
