Hi,Please check error.logs when you drag & drop the component. It might be possible that the component is breaking and thereby rendering as blank.ThanksNitin

Thanks for your response Peter. Yes It's not yet added in the AEM's list of Script Engines. That's the reason I am trying to load it directly from JDK considering nashorn.jar is already in the classpath.ScriptEngineManager engineManager = new ScriptEngineManager();ScriptEngine engine = engineManager...

For the Handlebar Compilation & processing we were loading the Nashorn Script Engine inside AEM & the Nashorn will be used to evaluate handlebars.js & other processing. I am loading the Nashorn en...

Hi Justin,The engine @ http://svn.apache.org/repos/asf/sling/whiteboard/ieb/handlebars/ use jknack which is a java based implementation of handlebars. We have already used it for our Server Side Java based Execution. What we are trying to do here is Server Side JS Based Execution.ThanksNitin 

Hi Justin,This cast is from JDK docs it seems AEM hasn't implemented it in the same way as JDK has done.http://docs.oracle.com/javase/7/docs/technotes/guides/scripting/programmer_guide/ThanksNitin

Sorry I didn't pasted code in the issue itself. So, We are trying to execute handlebar templates inside AEM. We want to render these templates using a JS Engine, so if tomorrow we need to replace handlebar with other templating language as dust etc, we can do the same. I am able to load the Rhino sc...

We don't want to do it using a Java bundle for handlebar as we want to have the flexibility of replacing handlebars with dust or react in future & although we have a Java based Processor for Handlebars (jknack) , not sure if we will have for other templating languages or not. We wanted to use Nashor...

Hi All We are trying to execute handlebar templates via a Script Engine Inside AEM.
