Hi
First, the usual stuff: running Firefox off branch MOZILLA_1_8_0, i.e.
somewhere between 1.5.0.3 and 1.5.0.4 for the debug build. Same result
on precompiled 1.5.0.4.
My problem is that I always get a NS_ERROR_NOT_INITIALIZED exception
when I try to add text to a dynamically generated <editor> (for the test
case, see below). Alas, this is what my debug build tells me after I
click the button which triggers the text insertion:
###!!! ASSERTION: bad action nesting!: 'mActionNesting>0', file
/Users/awuest-devel/Documents/devel/src/mozilla/trees/MOZILLA_1_8_0_BRANCH/mozilla/editor/libeditor/html/nsHTMLEditRules.cpp,

JavaScript error: , line 0: uncaught exception: [Exception... "Component

(NS_ERROR_NOT_INITIALIZED)" location: "JS frame ::
chrome://test/content/controller-test.js :: addText :: line 58" data: no]
Now, to the test case. If I embed the editor directly in my XUL file,
everything works flawlessly:
editor-test.xul:
----------------
<window id="uiEditorWindow"
orient="horizontal"
align="stretch"
onload="initEditor()"
xmlns="http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul";>
<script type="application/x-javascript"
src="chrome://test/content/controller-test.js"/>
<button label="Add Text" oncommand="addText()"/>
<editor id="uiEditor" type="content" flex="1" style="border: 2px
solid black; margin: 2px 2px 2px 2px;" onload="event.stopPropagation();"/>
</window>
controller-test.js:
-------------------
var gEditor = null;
function initEditor() {
var editorElem = null;
// set up
editorElem = document.getElementById("uiEditor");
editorElem.makeEditable("text", false);
gEditor = editorElem.getEditor(editorElem.contentWindow);
gEditor.QueryInterface(Components.interfaces.nsIPlaintextEditor);
editorElem.contentWindow.addEventListener("keypress", function
(event) { event.preventBubble(); }, true);
dump("editorElem status = \"" +
editorElem.editingSession.editorStatus + "\"\n");
}
function addText() {
gEditor.insertText("Hello?");
}
As soon as I generate the editor dynamically, the error mentioned above
occurrs, and no text is inserted (nor is it possible to add text via
typing).
editor-test.xul:
----------------
<window id="uiEditorWindow"
orient="horizontal"
align="stretch"
onload="initEditor()"
xmlns="http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul";>
<script type="application/x-javascript"
src="chrome://test/content/controller-test.js"/>
<button label="Add Text" oncommand="addText()"/>
</window>
controller-test.js:
-------------------
var gEditor = null;
function initEditor() {
// test dynamic tab insertion
var editorWindow = null;
var editorElem = null;
editorElem =
document.createElementNS("http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul";,
"editor");
editorElem.setAttribute("type", "content");
editorElem.setAttribute("flex", "1");
editorElem.setAttribute("style", "border: 2px solid black; margin:
2px 2px 2px 2px;");
editorElem.setAttribute("onload", "event.stopPropagation()");
editorWindow = document.getElementById("uiEditorWindow");
editorWindow.appendChild(editorElem);
// set up
editorElem.makeEditable("text", false);
gEditor = editorElem.getEditor(editorElem.contentWindow);
gEditor.QueryInterface(Components.interfaces.nsIPlaintextEditor);
editorElem.contentWindow.addEventListener("keypress", function
(event) { event.preventBubble(); }, true);
dump("editorElem status = \"" +
editorElem.editingSession.editorStatus + "\"\n");
}
function addText() {
gEditor.insertText("Hello?");
}
I hope somebody could give me a pointer on what I am doing wrong. I have
a suspicion it might be related to a command controller, but I am not
sure (nor how I would add one which implements insertText, because, with
what exactly should I implement it, and anyway, with a static editor, it
all works fine!).
