hmm ... {{<s:param/>}} has nothing to this issue ... when I have dropped all
those extra tags, it still the same.

> Project: Struts 2
> Issue Type: Bug
> Components: Other

> 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:
> {code:xml}
> <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>
> {code}
> Note that param body is rendered inside someTemplate.jsp like this:
> {code:xml}
> <s:property value="%{parameters.body}" escapeHtml="false" />
> {code}
> eg. This will work exactly as expected:
> {code:xml}
> <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>
> {code}
> Note that the "if" tag can be any struts tag and it will work.
