Subject [jira] Created: (TAP5-742) Add optional component tracing comments to rendered output
Date Wed, 10 Jun 2009 12:42:07 GMT
Add optional component tracing comments to rendered output

                 Key: TAP5-742
                 URL: https://issues.apache.org/jira/browse/TAP5-742
             Project: Tapestry 5
          Issue Type: New Feature
          Components: tapestry-core
    Affects Versions:
            Reporter: Howard M. Lewis Ship
            Priority: Minor

In complex pages, it can be hard to work backwards from a bit of output HTML in the browser,
back to the component that originated the markup.

A special mode could be enabled where components would render a comment before and after rendering:

<!-- BEGIN: Index:layout.pagelink -->
<a href="dashboard">Dashboard</a>
<!-- END: Index:layout.pagelink -->

This would bloat and clutter the application (a lot!) but would be useful, on occasion.  One
possibility would be a special query parameter to enable this on a request-by-request basis,
i.e., ?t:component-trace=true
