[jira] Commented: (WICKET-2826) Wicket fails to read html markup
from jar after updating and redeploying in jetty
[ https://issues.apache.org/jira/browse/WICKET-2826?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12903265#action_12903265 ]
Juergen Donnerstag commented on WICKET-2826:
--------------------------------------------
There is one welknown issue. If the page has been loaded once, all associated markup files (in case of inheritance more than one file) are cached. Wicket will not recognize if you added a new markup for that page, since the cache already returns true and ModificationWatcher doesn't trigger because it's new and not yet in his list of markup file to watch. What that means: in doubt clear the markup cache (e.g. via jmx or Debug Inspector)

> Project: Wicket
> Issue Type: Bug

> I wrote a web application and packaged the main code and html markup files into a jar. I deployed it in jetty using the "extracted war" folder structure and a context descriptor. The application worked fine.
> Then I made a minor change in an html file, rebuilt the jar, copied it over the old one in jetty and touched the descriptor to reload the context. Then when trying to access the application in the browser, I got errors like:
