Subject [jira] [Commented] (WW-4422) Component inside Component - "Could not render JSP template"
Date Wed, 21 Sep 2016 06:33:20 GMT

    [ https://issues.apache.org/jira/browse/WW-4422?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15508935#comment-15508935

Lukasz Lenart commented on WW-4422:
-----------------------------------

Thanks [~sdutry]! I have tested with prior versions and the result is the same - it never
worked. I think the problem lays in behaviour of {{<s:param/>}} tag which doesn't generate
{{body}}, it just passes value to an ancestor and returns {{false}} which means for JSPs to
stop rendering. You can observe this behaviour by moving {{<s:if test="">}} tag above
{{<s:component template="template2.jsp" theme="sdutry">}} - the page will fail the same.

> 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.
