> 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.
> @Name("wikiTextEditor") 
> @Scope(ScopeType.PAGE) 
> public class WikiTextEditor
> {
>    private String textAreaSize;
>    @WebRemote
>    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() {}
> </script>
