"FCK is not defined" after clicking save

Hi,

I create the editor by replacing a textarea that is added dynamically. This might be weird but using fck.CreateHTML for innerHTML worked, but I was not able to set a Value, because I had to wait until the editor was available in FCKeditorAPI. Or is there another way to set Values????

/**
 * @param {Object} obj The HTML-DOM object of the element to be edited
 * @param {String} id The id of the HTML element
 */ 
function createEditorAtObject(obj, id){
    // we will use a WYSIWYG editor now
    var fck = new FCKeditor('myFCKeditor__'+ id);
    fck.BasePath = 'javascript/fckeditor/'; 
    // creation with Create didn't work, so we create a text area and then replace it
    obj.innerHTML = "<form onsubmit=''><textarea cols='85' rows='5' type='text' id='myFCKeditor__"+ id +"' >"+ value +"</textarea></form>";
    fck.ReplaceTextarea();
}

function mySaveFunction(){
    // get the editor from the <form> element (this)
    var completeid = this.firstChild.id.split('__');                     // creating with fck.CreateHTML had problems getting the instance
    var editorId = completeid[0] + '__' + completeid[1];
    var oEditor = FCKeditorAPI.GetInstance(editorId);              // I do get the editor
    // get the parent Element and replace editor with 
    var myobj = this.parentNode;                                            // I get the parent element and replace the editor with the value
    myobj.innerHTML = oEditor.GetData();                              // works
   
    // delete instances
    delete(oEditor);
    delete(FCKeditorAPI.Instances[editorId]);
    
    return false; //this disables default action (submitting the form)
}

function FCKeditor_OnComplete( editorInstance ){
    editorInstance.LinkedField.form.onsubmit = mySaveFunction;
}

Now clicking on the save button, gives me a "FCK not defined" and I can't find a solution. Saving works but I don't want to have JS errors in FF????
