[jira] [Reopened] (TAP5-2448) Asset.getClientURL() throws NPE if the Asset is a Folder within a SubModule JAR file

----------------------------------

Tapestry should not throw an NPE like that. If we cannot prevent the creation of an Asset that references a folder, we should at least report the error in a helpful way.

> If you inject in a Field an Asset and if this Asset is actually a Folder that is embedded into a JAR SubModule used by the main Tapestry WebApp then the method toClientURL() returns a NPE.
> The issue does not happen when the SubModule is not yet a JAR file. Exemple : when you are running Tomcat from Eclipse and let Eclipse manage the dependency ( I am using the Sysdeo plugin to add dependencies to the source folders of the SubModule instead of the JAR file. ).
