    <p>I'm trying to set up my first scala lift project in Eclipse and it is Not Simple (TM).</p> <p>What I have done is set up the project trough Maven with the following</p> <pre><code>mvn archetype:generate -U \ -DarchetypeGroupId=net.liftweb \ -DarchetypeArtifactId=lift-archetype-basic_2.9.1 \ -DarchetypeVersion=2.4-SNAPSHOT \ -DarchetypeRepository=http://scala-tools.org/repo-releases \ -DgroupId=demo.helloworld -DartifactId=helloworld -Dversion=1.0-SNAPSHOT </code></pre> <p>I then created an eclipse project from this with <code>mvn eclipse:eclipse</code> (because it's hellish to figure out all the dependencies, and add them all to the build path manually)</p> <p>The project then conflicts with the installed Scala version. So I removed the three existing references to scalalang from the buildpath, and added my own scala to the buildpath. I'm using scala 2.9.0.</p> <p>Now the project can be built, but when I try to run RunWebApp, an exception is thrown:</p> <pre><code>Exception in thread "main" java.lang.NoClassDefFoundError: RunWebApp Caused by: java.lang.ClassNotFoundException: RunWebApp at java.net.URLClassLoader$1.run(URLClassLoader.java:217) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:205) at java.lang.ClassLoader.loadClass(ClassLoader.java:321) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:294) at java.lang.ClassLoader.loadClass(ClassLoader.java:266) Could not find the main class: RunWebApp. Program will exit. </code></pre> <p>I'm aware of the answer on <a href="https://stackoverflow.com/questions/3245715/scala-lift-project-in-eclipse-scala-ide-errors">Scala-Lift project in Eclipse Scala IDE errors</a> suggesting to ask the question on <a href="http://groups.google.com/group/scala-ide-user" rel="nofollow noreferrer">http://groups.google.com/group/scala-ide-user</a> yet I hoped someone here could point me to the answer in a way someone else with the same problem might find the answer too</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.
