      Description

      I get an error whenever I include an <fd:selection-list src="cocoon:/XYZ"> where
      both the form and the XYZ pipeline use JavaFlow. The error is:

      No continuation is running
      cause: java.lang.IllegalStateException: No continuation is running
      java.lang.IllegalStateException: No continuation is running
      at
      org.apache.cocoon.components.flow.java.Continuation.suspend(Continuation.java:79)
      at
      org.apache.cocoon.components.flow.java.AbstractContinuable.sendPageAndWait(AbstractContinuable.java:75)
      at org.apache.cocoon.forms.flow.java.FormInstance.show(FormInstance.java:181)

      The reason is that when cocoon:/XYZ runs, a continuation is created for the same
      thread as the form continuation. The continuationsmap in Continuation class gets
      overwritten. When cocoon:/XYZ returns, the map is cleared for the thread,
      leaving no continuation for the form.

      Here's a bit of code from the app to help explain.

      The form contains a selection list defined as:
      <fd:field id="user">
         <fd:datatype base="string"/>
         <fd:selection-list src="cocoon:/UserSelectList" dynamic="true"/>
      </fd:field>

      The sitemap contains:
      <map:match pattern="UserSelectList">
         <map:call function="generateUserList"/>
      </map:match>

      Then I have the following JavaFlow
      public void doGenerateUserList() throws Exception {
         Collection userList = databaseManager.getUserList();
         sendPage("user_list", new VarMap().add("list", userList) );
      }
