    <p>I installed Eclipse Helios and m2eclipse. Next I created a maven project. Now Eclipse goes crazy. It leaks all the time, goes in endless loops (continously 50% CPU), throws PermGen Space Errors and crashes. I can't work.</p> <p>I tried to substitute the JDK with an older version, the same with maven and the same with eclipse. I also changed the size of my PermGen Space.</p> <p>Has somebody an Idea what's wrong? Or does that remembers somebody about a known bug? May there be a problem with my Windows XP?</p> <p>Her are some Errors from my Workspace/Metadata/.log:</p> <pre><code>eclipse.buildId=I20100608-0911 java.version=1.6.0_20 java.vendor=Sun Microsystems Inc.

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).
