    <p>We're using Freemarker version 2.3.16, and I've just tracked down a weird bug in one of our apps. It came down to there now being hyphens in some of our product code strings. The codes are used to pull hashes of localized text from the global scope using <code>.vars</code>. </p> <p>Reducing the issue brought me to an example that anyone can try: </p> <ul> <li><p><code>${.vars["foo-bar"]}</code> in a template outputs <code>0</code></p></li> <li><p><code>${.vars["foo+bar"]}</code> outputs <code>nullnull</code> </p></li> <li><p><code>${.vars["foobar"]}</code> correctly triggers an InvalidReferenceException</p></li> </ul> <p>All three should trigger exceptions. Instead, it appears the <code>.vars</code> parameter string is being evaluated! :-(</p> <p><a href="http://freemarker.sourceforge.net/docs/app_faq.html#faq_strange_variable_name" rel="nofollow">http://freemarker.sourceforge.net/docs/app_faq.html#faq_strange_variable_name</a> implies this should work. </p> <p>I saw mention of a similar issue a few weeks ago on the Freemarker mailing list, and it was suggested to prefix the parameter string with "@". That might work with other hashes, but it does NOT work with <code>.vars</code>. I just took a working example (<code>.vars["resources_title"]</code>) and changing it made it throw an InvalidReferenceException (<code>.vars["@resources_title"]</code>). I also tried it on the hyphenated reference, and it also threw the exception.</p> <p>Upgrading to 2.3.18 did not seem to make a difference.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
