Hi,
I'm a newbie with Alfresco and webscript and I cant figure what I make wrong in my implementation.
After much seeking in the wiki and in the forum, you're my last hope
I wrote a webscript with a java controller which returns a "model" object but my ftl template can't access it and returns "undefined expression".
I'm sure, through some logging, that the webscript executes and the java controller works, but the model (declared as: Map<String, Object> model = new HashMap<String, Object>() and returned by the executeImpl method of a class which extends org.alfresco.web.scripts.DeclarativeWebScript ) doesn't seem to be transmitted to the ftl template.
Any idea?
Here is some snapshots of my code:
constrval.get.desc.xml in alfresco/WEB-INF/classes/alfresco/templates/webscripts/mydomaintree/myapp/:
