[opencms-dev] Looping over files -> use expression language; macros are triggered by %()

Hello Peter,

first, since version 7.0.0 or so the macros like opencms.filename are marked by
%() instead of ${} to avoid problems with expression language eg.
%(opencms.filename).


Then I would recommend to use expression language instead of cms:contentschow
and cms:contentloop.



Short examples are to find in the javadoc:

http://files.opencms.org/javadoc/core/org/opencms/jsp/util/CmsJspContentAccessBean.html#getValue()
and
http://files.opencms.org/javadoc/core/org/opencms/jsp/util/CmsJspContentAccessBean.html#getValueList()

instead of ${opencms.filename} you should use
http://files.opencms.org/javadoc/core/org/opencms/jsp/util/CmsJspContentAccessBean.html#getFilename()

For more detailed examples have a look at linkbox.jsp, listbox.jsp and
textbox.jsp in the elements folder of the template two demo in the module
org.opencms.frontend.templatetwo


Regards Thommy

Hi!

 I'm developing a website using OpenCMS and am having a problem with creating
links to files over which I loop using cms:contentload:


  <cms:contentload collector="allInFolder" param="ePass/faqs/|FaqFile"
editable="false">
    <%-- create a date object from date value --%>
      <% int i = 0; %>

      <cms:contentcheck ifexists="Subcategories">
      <cms:contentloop element="Subcategories">
         <cms:contentloop element="Faqs">
          <% i++; %>
         </cms:contentloop>
      </cms:contentloop>
     </cms:contentcheck>
     <b><a href="${opencms.filename}"><cms:contentshow element="Title"
/></a></b> (<%= i %> answers) <br />
  </cms:contentload>

 This is part of the index.jsp file. All the links unfortunately lead to
index.jsp and not to the individual FAQ files. Do you know how to change this?

 Thanks,
 Peter

I'm looping over a bunch of files and the macro should resolve to the filename of the FaqFile file currently read, but it always resolves only to the filename of the file in which this loop is made (i.e. it stays the same, "index.jsp"). Is there any workaround to this?
