        ========중략========

오류 정의 : 'content' Attribute 된 프로퍼티가 없어서 생긴 문제.

tlies를 설정한 .xml 의 definition 프로퍼티 중 content가 다 들어가있는지 확인하자

content는 꼭 들어 가야한다. 

 

Solution

   <definition name="*/*" extends="main_template">
        <put-attribute name="res" value="{1}/{2}" />
    </definition>

<put-attribute name="content" value=""/> 삽입

   <definition name="*/*" extends="main_template">
        <put-attribute name="res" value="{1}/{2}" />
        <put-attribute name="content" value=""/>
    </definition>
