      Description

      Trying to render a Component inside a Component will fail with logged error "JspTemplateEngine.error(34) | Could not render JSP template". There is a workaround, which is simply to have ANY struts tag after the inner component declared in the <param> of the outer component. Also, the inner component only causes this failure when it has struts tags inside it.

      eg. This fails:

      <s:component ... template="someTemplate.jsp">
        <s:param name="body">
          <s:component ... template="otherTemplate.jsp"><!-- only fails if there is struts tag(s) inside otherTemplate.jsp -->
            <!--other params-->
          </s:component>
        </s:param>
      <s:component>
      

      Note that param body is rendered inside someTemplate.jsp like this:

      <s:property value="%{parameters.body}" escapeHtml="false" />
      

      eg. This will work exactly as expected:

      <s:component ... template="someTemplate.jsp">
        <s:param name="body">
          <s:component ... template="otherTemplate.jsp"><!-- only fails if there is struts tag(s) inside this template -->
            <!--other params-->
          </s:component>
          <s:if test=""><!-- DO NOT DELETE THIS LINE - Fixes "component inside component" bug in Struts 2.3.16.3 --></s:if>
        </s:param>
      <s:component>
      

      Note that the "if" tag can be any struts tag and it will work.
