    <p>I discovered backtype.storm.Testing while reading <a href="https://stackoverflow.com/questions/16549265/testing-storm-bolts-and-spouts">this SO question</a> and got excited, but I haven't been able to get it to work because when I actually go to run the tests (from Java), the testing class won't load.</p> <p>I wanted to use the functions from Testing exhibited in <a href="https://github.com/xumingming/storm-lib/blob/master/src/jvm/storm/TestingApiDemo.java" rel="nofollow noreferrer">xumingming's TestingApiDemo</a>, but when I actually run the tests I'm getting an ExceptionInInitializerError followed by a bunch of NoClassDefFoundErrors because it couldn't initialize backtype.storm.Testing.</p> <p>What's going wrong with Testing? There's no problem at compile-time. My best guess is that it needs something from Clojure which is being dynamically loaded at runtime. Has anyone else seen this?</p> <p>Here's most of the relevant stack trace:</p> <pre><code>java.lang.ExceptionInInitializerError: null at java.net.URLClassLoader$1.run(URLClassLoader.java:202) at

rel="nofollow noreferrer">I found the place</a> where I think the Testing class is being generated using Clojure. Perhaps the version of the Clojure libraries being used by my project (1.4) don't supply some necessary type in here? I'm using Storm 0.8.2.</p> <p>Thanks,</p> <p>-Daniel</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.

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).
