[opencms-dev] need help getting my launcherClass invoked

[Vincent Hanniet]

Hi,
You probably need to create a custom launcher and associate your custom 
resource type to the new launcherType in the registry.
Matt Butcher describes how to do in his book. Basically you have to 
implement I_CmsLauncher.

(problem is you lose the custom properties as well as proper URL path of the destination, if needed, if the resource isn't redirected to).

A "fix" I realized after looking @ the source is after browsing to the link destination, replace your root site's name with "../" (assumption is the links will/are always one directory deep under the root ... add "../" instances as needed).  The workplace dialog posts an error as it "can't find it", but it lets you continue.  End result is the page is indeed redirected to and custom properties added to the resource to alter functionality works.  Problem though is it's not as user friendly as I need for my content creators; and you =know= they're going to forget to replace the "/root_name/" with "../"!

Turns out by testing it isn't, and thus my launcherClass is not being invoked.
