[opencms-dev] Displaying the content

The value you use for __element presumably depends on which element it is
whose content you want to display.

that value I use for __element? 

 

<cms:include page="commons/banners_head.html">
    <cms:param name="__element" value="???" />
</cms:include>         


Thanks

Don't know if this helps, but from a quick scan through the source code,
this seems to imply that the request parameter named
I_CmsResourceLoader.PARAMETER_ELEMENT (i.e. "__element") is not defined, and
hence the creation of the corresponding Xpath expression fails.

Subject: [opencms-dev] Displaying the content



Hi all,

I am trying to display the content of a News item in a JSP in the same
directory, but keep getting an NPE. The code below shows a minimal
example:

------- Display_News.jsp -----------------
<%@ taglib prefix="cms" uri="http://www.opencms.org/taglib/cms"
<http://www.opencms.org/taglib/cms%22>  %>
<% org.opencms.jsp.CmsJspActionElement cms = new
org.opencms.jsp.CmsJspActionElement(pageContext, request, response); %>

<cms:include page="New_News.html" />
-------------------------------------------

The exception begins:

java.lang.NullPointerException
at org.opencms.xml.CmsXmlUtils.createXpath(CmsXmlUtils.java:144)
at
org.opencms.xml.A_CmsXmlDocument.getLocales(A_CmsXmlDocument.java:255)
at
org.opencms.loader.A_CmsXmlDocumentLoader.dumpAsString(A_CmsXmlDocumentL
oader.java:118)
at
org.opencms.loader.A_CmsXmlDocumentLoader.service(A_CmsXmlDocumentLoader
.java:238)


Does anyone have any ideas on what I am doing wrong here? (What I am
actually trying to do is iterate over the news items in the folder and
display the teaser text. The iteration is working fine, but I cannot get
the content of the news item itself...)

Thanks,
