I am using Nuxeo 5.6 RC2 for document templating. I made a custom schema to use the variables in document template.

I did the following:

1. Created a custom schema,“template” with prefix “tem” and registered.

   < extension target="org.nuxeo.ecm.core.schema.TypeService" point="schema">
< schema name="template" prefix="tem" src="data/schemas/template.xsd" /> < /extension> `

2. Extended it to the “Document

   < extension target="org.nuxeo.ecm.core.schema.TypeService" point="doctype">
< doctype name="template" extends="Document">
< schema name="template" />
< schema name="dublincore" />
< schema name="common" />
< schema name="uid" />
< schema name="file" />
< facet name="Downloadable" />
< facet name="Versionable" />

   <br>
   

   < facet name="HasRelatedText" />

   <code> < /doctype>
   

   < /extension>

3. Created screens to store custom schema,property(e.g tem:prop).I am successfully able to store the values.Hence,this confirms that my schema registration and value storage is fine.

4. i use the variable in the document template like this:

   <#list This as doc> ${doc[“tem:prop”]}” < /#list>
