[opencms-dev] Apply template on nested xmlcontent

[Stephan Hartmann]

Hi Thomas,

You cannot pass objects as request parameters (that's what cms:param tag
does).
Instead you could either store your object in request scope and then access
it in your included JSP.

Including JSP:

<cms:contentloop element=*"options"*>

       <cms:contentaccess var=*'optionContent'* scope="request" />

                <cms:include file=
*"/system/modules/cn.bmw.opencms.mysql.ecrm/templates/option.jsp"*/>
</cms:contentloop>

Included JSP (no contentload needed!):

<c:if test="${optionContent.hasValue['value']">
  ${optionContent.value.value}
...
</c:if>
<c:if test="${optionContent.hasValue['text']">
  ${optionContent.value.text}
...
</c:if>

or you could pass your string values as request parameters:
<cms:include ...>
  <cms:param name="optionValue" value="${optionContent.value.value}"/>
  <cms:param name="optionText" value="${optionContent.value.text}"/>

</cms:include>

and access them as follows:
${param.optionValue}
${param.optionText}

HTH,
Stephan
