Ext.ux.TinyMCE: Render form into the page

If you render Ext.ux.TinyMCE component right in the Ext.onReady handler, then you must manually initialize tinyMCE by calling Ext.ux.TinyMCE.initTinyMCE() method. This should be done during page load process (i.e. before onReady).

Before you can submit a form with Ext.ux.TinyMCE you have to sync editor value with hidden textarea behind it. Use either tinyMCE.triggerSave() method to sync all editors on page at once, or syncValue() method of our component to sync only specific editor instance.
