Hi guys, I'm facing a strange problem. Inside a facet which is a scaffold provider I need to load a resource for MetaWidget. I can see printing this from the method that needs the resource this.getClass().getClassLoader().getResource("scaffold/errai/metawidget-formbean.xml") that the file is available: file:/Users/lucamasini/.forge/plugins/org/jboss/forge/forge-scaffold-errai/1.0.6-SNAPSHOT-e0a249f3-6fe7-4ea1-8fd9-680f8e422af4/forge-scaffold-errai.jar!/scaffold/errai/metawidget-formbean.xml but inside the SimpleResourceResolver neither: ClassLoader loaderContext = Thread.currentThread().getContextClassLoader(); or: InputStream stream = getClass().getResourceAsStream( resource ); can find the resource because the "forge-scaffold-errai.jar" is not one of the JAR used by the current classloader (which is a JBoss's ModuleClassloader). The current implementation of scaffolding for faces works because is inside the forge itself, but I think we have some problems using it in an external plugin. Do you think I need to declare it in some kind of manifest ?? Thank you L. -- **************************************** http://www.lucamasini.net http://twitter.com/lmasini http://www.linkedin.com/pub/luca-masini/7/10/2b9 ****************************************

Well... we know this is a problem in Forge 1, which is one of the big reasons we are working on Forge 2. But you might want to take a look at the Spring MVC scaffold, which had to overcome this same issue: https://github.com/forge/plugin-spring-mvc/blob/master/src/main/java/org/... Note the special template resolver. ~Lincoln PS. Sorry for the late reply.

Right now if it works, do it. That's probably the only best practice I can give you for the Scaffold in Forge 1. It's really not a great design (my fault.) But it was also never designed to go this far without being re-written :) Most likely, we will need to wait to address this in Forge 2.
