Advanced Control Flow - Velocity

+ +

Velocity Generator

+
+

If called from a Flowscript, the Cocoon +Velocity +Generator provides access to the immediate properties of +the context object passed to +cocoon.sendPage and +cocoon.sendPageAndWait. In +addition, the current +WebContinuation is also +available as a variable named $continuation. You would typically access +its id:

+
  <form action="$continuation.id">
+
+

You can also reach previous continuations by using the getParent() +function:

+
  <form action="$continuation.getParent().id" >
+
+

In addition the following implicit objects are always available in the +Velocity context:

+
    + +
  • + +Request +$request : The current Cocoon request
    • + +
  • + +Response +$response : The Cocoon response associated with the current request +
    • + +
  • + +Session +$session : The Cocoon session associated with the current request
    • + +
  • + +Context +$context : The Cocoon context associated with the current request
    • + +
  • +org.apache.avalon.framework.parameters.Parameters +$parameters : Any parameters passed to the generator in the pipeline +
    • + +
+

Cocoon installs a Velocity introspector that makes it possible for you to +access JavaScript objects and arrays in your templates, as well as Java objects. +For example, assuming you had a Flowscript like this:

+
    sendPage("myTemplate.vm", {colors: ["red", "blue", "yellow"]});
+
+

You could do this in myTemplate.vm:

+
    <select name="colors">
+    #foreach ($color in $colors) 
+      <option value="$color">$color</option>
+    #end
+    </select>
+
