    <p>I've got a problem with starting my GWT project in tomcat, since I'm using a new one. Yesterday I used a tomcat instance, which i installed as a service on my PC and it worked well. Today I uninstalled it because it didn't have a startup.dat and I needed one to debug in eclipse.</p> <p>Nevermind... now I started tomcat via startup.bat and deployed my war. But when I want to start it I'm getting some errors.</p> <pre> > FAIL - Application at context path /WebApp could not be started FAIL - Encountered exception org.apache.catalina.LifecycleException: Failed to start component [StandardEngine[Catalina].StandardHost[localhost].StandardContext[/WebApp]] </pre> <p>I found this in the catalina log. It might help u.</p> <pre> >14.03.2013 14:07:15 org.apache.catalina.core.ContainerBase addChildInternal SCHWERWIEGEND: ContainerBase.addChild: start: org.apache.catalina.LifecycleException: Failed to

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).
