    <p>I'm having problems with a java.lang.NoClassDefFoundError when trying to run my JUnit tests from ANT using the runtestsreport task in thefollowing build.xml; I know the other tasks work, it's just the actual running of the tests that's the problem.</p> <p>I've tried lots of adjustments based on questions posted on here but I can't fix it; what I really need is a dev to pair with but they've all gone home for the day. </p> <p>Can anyone help?</p> <p>The build.xml file is </p> <p> </p> <pre><code>&lt;property name="build" location="C:\&lt;path on my machine&gt;\workspace\ESS\build"/&gt;

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
