> 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>
