    <p>So I have a Scalatra app (using Scalatra 2.2.1). I'm building views using Scalate; I've decided to go with the Jade/Markdown one-two. Only one problem: if I try to use markdown in a jade template (started with the <code>:markdown</code> tag), I get this:</p> <pre><code>scala.Predef$.any2ArrowAssoc(Ljava/lang/Object;)Lscala/Predef$ArrowAssoc; java.lang.NoSuchMethodError: scala.Predef$.any2ArrowAssoc(Ljava/lang/Object;)Lscala/Predef$ArrowAssoc; at org.fusesource.scalamd.Markdown$.&lt;init&gt;(md.scala:119) at org.fusesource.scalamd.Markdown$.&lt;clinit&gt;(md.scala:-1) at org.fusesource.scalate.filter.ScalaMarkdownFilter$.filter(ScalaMarkdownFilter.scala:32) at org.fusesource.scalate.RenderContext$class.filter(RenderContext.scala:276) at org.fusesource.scalate.DefaultRenderContext.filter(DefaultRenderContext.scala:30) at org.fusesource.scalate.RenderContext$class.value(RenderContext.scala:235) at org.fusesource.scalate.DefaultRenderContext.value(DefaultRenderContext.scala:30) at templates.views.$_scalate_$about_jade$.$_scalate_$render(about_jade.scala:37) at templates.views.$_scalate_$about_jade.render(about_jade.scala:48) at org.fusesource.scalate.DefaultRenderContext.capture(DefaultRenderContext.scala:92) at org.fusesource.scalate.layout.DefaultLayoutStrategy.layout(DefaultLayoutStrategy.scala:45) at org.fusesource.scalate.TemplateEngine$$anonfun$layout$1$$anonfun$apply$mcV$sp$1.apply$mcV$sp(TemplateEngine.scala:559) at org.fusesource.scalate.TemplateEngine$$anonfun$layout$1$$anonfun$apply$mcV$sp$1.apply(TemplateEngine.scala:559) at org.fusesource.scalate.TemplateEngine$$anonfun$layout$1$$anonfun$apply$mcV$sp$1.apply(TemplateEngine.scala:559) </code></pre> <p>So that's pretty cool. The error vanishes as soon as I remove the <code>:markdown</code> flag, and beyond that everything compiles (beyond markdown not getting rendered correctly).</p> <p>Things I know and have found so far:</p> <ol> <li>There's some thought that this error is the biproduct of incompatible Scala versions somewhere in the build. My build.scala defines Scala version as 2.10.0, which Scalatra is explicitly compatible with.</li> <li>...that said, I have <em>no idea</em> which version of Scalate Scalatra pulls in, and my attempts to override it have not worked so far. I know the current stable of Scalate (1.6.1) is only compatible up to Scala 2.10.0 -- but that's what I'm using.</li> <li>I am, however, sure that my classpath is clean. I have no conflicting Scala versions. <em>Everything</em> is 2.10.0 in the dependencies. </li> </ol> <p>Has anybody worked with this one before? Any ideas? </p> <h3>EDIT</h3> <p>Per request, here are my build definitions:</p> <pre><code>//build.sbt libraryDependencies += "org.scalatest" %% "scalatest" % "2.0.M5b" % "test" libraryDependencies += "org.twitter4j" % "twitter4j-core" % "3.0.3" libraryDependencies += "org.fusesource.scalamd" % "scalamd" % "1.5" //build.properties sbt.version=0.12.3 //build.scala import sbt._ import Keys._ import org.scalatra.sbt._ import org.scalatra.sbt.PluginKeys._ import com.mojolly.scalate.ScalatePlugin._ import ScalateKeys._ object TheRangeBuild extends Build { val Organization = "com.gastove" val Name = "The Range" val Version = "0.1.0-SNAPSHOT" val ScalaVersion = "2.10.0" val ScalatraVersion = "2.2.1" lazy val project = Project ( "the-range", file("."), settings = Defaults.defaultSettings ++ ScalatraPlugin.scalatraWithJRebel ++ scalateSettings ++ Seq( organization := Organization, name := Name, version := Version, scalaVersion := ScalaVersion, resolvers += Classpaths.typesafeReleases, libraryDependencies ++= Seq( "org.scalatra" %% "scalatra" % ScalatraVersion, "org.scalatra" %% "scalatra-scalate" % ScalatraVersion, "org.scalatra" %% "scalatra-specs2" % ScalatraVersion % "test", "ch.qos.logback" % "logback-classic" % "1.0.6" % "runtime", "org.eclipse.jetty" % "jetty-webapp" % "8.1.8.v20121106" % "compile;container", "org.eclipse.jetty.orbit" % "javax.servlet" % "3.0.0.v201112011016" % "compile;container;provided;test" artifacts (Artifact("javax.servlet", "jar", "jar")) ), scalateTemplateConfig in Compile &lt;&lt;= (sourceDirectory in Compile){ base =&gt; Seq( TemplateConfig( base / "webapp" / "WEB-INF" / "templates", Seq.empty, /* default imports should be added here */ Seq( Binding("context", "_root_.org.scalatra.scalate.ScalatraRenderContext", importMembers = true, isImplicit = true) ), /* add extra bindings here */ Some("templates") ) ) } ) ++ seq(com.typesafe.startscript.StartScriptPlugin.startScriptForClassesSettings: _*) ) } </code></pre>

    2. COSure. Are you interested in just the main `build.sbt`, or the stuff in `project/` as well?

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).
