Did this accepted answer work for anybody? I deployed 2 aem spas, lets call it spa1 & spa2, to my local author. I updated the page policies of spa2 to include components from spa1. In a spa2 page, I am able to see and add spa1 components, but then nothing is shown on the page. 

I am running into the same issue as you. I am running AEM 6.5 and acs 4.3.2.@smacdonald2008 or anyone else at Adobe, is it possible to store the values as json on AEM 6.5?

Hi All,I am trying to migrate my site from AEM 6.2 to AEM 6.3 and I get the following error. Does anyone know what is causing this error?org.apache.sling.api.scripting.ScriptEvaluationException: org.apache.sling.scripting.jsp.jasper.JasperException: Unable to compile class for JSP: An error occurred...
