Default Exception Report Page should have a link to discard component class
loader and retry
--------------------------------------------------------------------------------------------
Key: TAP5-1820
URL: https://issues.apache.org/jira/browse/TAP5-1820
Project: Tapestry 5
Issue Type: Improvement
Components: tapestry-core
Affects Versions: 5.3, 5.4
Reporter: Howard M. Lewis Ship
Sometimes you attempt to reach a page, but it doesn't exist because of a syntax
error.
Even after you create the page and reload, Tapestry may not pick up the change
because it is not monitoring the directory containing the .class file, because
it didn't successfully load a file from that directory.
It would be nice if the exception report page included a link to discard the
class loader, forcing a reload of the page(s) for the request, and would then
redirect back to the page (or event request) that failed.
Caveats:
- Different handling for an Ajax request, where the class loader should be
discarded, and a response returned that will dismiss the exception report
iframe.
- POST requests may be tricky.
- The link should only appear if the request is white-listed (by default, from
localhost).
