No pages context exists during a remoting request

                 Key: JBSEAM-1989
                 URL: http://jira.jboss.com/jira/browse/JBSEAM-1989
             Project: JBoss Seam
          Issue Type: Bug
          Components: Remoting
    Affects Versions: 2.0.0.CR1
            Reporter: Shane Bryzak
         Assigned To: Shane Bryzak
             Fix For: 2.0.0.CR2

This was brought to my attention by Christian - page-scoped components such as the following cannot be invoked with remoting as the page context no longer exists during a remoting request.  Upon further investigation it seems that PageContext uses FacesContext (which isn't available for a non-JSF remoting request) so it's not just a trivial matter of creating a new PageContext for the request.  The fix for this could potentially be tied in with JBSEAM-280.

public class WikiTextEditor
   private String textAreaSize;

   public void setTextAreaSize(String textAreaSize)
      this.textAreaSize = textAreaSize;

   public String getTextAreaSize()
      return textAreaSize;

Javascript code to invoke the above component:

<script type="text/javascript" src="#{wikiPreferences.baseUrl}/seam/resource/remoting/interface.js?wikiTextEditor"></script>
<script type="text/javascript">
    /* Set text area resize on backing bean */
    Seam.Remoting.displayLoadingMessage = function() {};
    Seam.Remoting.hideLoadingMessage = function() {};

    var wikiTextEditor = Seam.Component.getInstance("wikiTextEditor");

    function storeTextAreaSize(size) {
        wikiTextEditor.setTextAreaSize(size, noopCallback);
    function noopCallback() {}
