Subject [jira] Commented: (TAPESTRY-2045) NoClassDefFound exception thrown when injecting DataTypeAnalyzer into a page
Date Tue, 15 Jan 2008 07:19:34 GMT

    [ https://issues.apache.org/jira/browse/TAPESTRY-2045?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12558945#action_12558945

Howard M. Lewis Ship commented on TAPESTRY-2045:

Exception is pretty clear:

"Service interface org.apache.tapestry.services.DataTypeAnalyzer is matched by 2 services:
DataTypeAnalyzer, DefaultDataTypeAnalyzer. Automatic dependency resolution requires that exactly
one service implement the interface."

Inside TapestryModule:

    public DataTypeAnalyzer build(List<DataTypeAnalyzer> configuration)
        return _chainBuilder.build(DataTypeAnalyzer.class, configuration);

Changing Start.java to:

public class Start
    @Inject @Primary
    private DataTypeAnalyzer _analyzer;

And all is well.

>          Issue Type: Bug
>          Components: tapestry-core
>    Affects Versions: 5.0.8
>         Environment: OS: OSX 10.5
> java version: 1.5.0_13

> 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.
