Hi there, working on a mini patch to add RichTextEmail.  Basically extending the echopointng.RichTextArea.  

I noticed that you had to reimplement the js files for textAreas to account for cursorupdating.  Which I am working through for the RichTextArea.

Are we using the patched textComponent.js echo2 framework that was put in around June...I think you submitted a patch 3 years ago?

In textArea you used a private static dummy class to instantiate echo2's textComponentPeer then replaced the js file with your own, adjusted version.  

This client-server interaction stuff is still requiring "hard work"  due to my inexperience is there any reason I cant call super() during my RichTextAreaPeer class and then do the replacement.  Given my class will be a direct extension of echopointng.RichTextAreaPeer.    I assumed I would need to implement cursor tracking to allow for macro expansion.  

I am just intending to implement a Rich Text area to use in mail creation dialogs.  I am not coding the entire project specification that includes the templating.

public class RichTextAreaPeer extends echopointng.ui.syncpeer.RichTextAreaPeer {

    public static final Service RICH_TEXT_SERVICE = JavaScriptService.forResource(
            "EPNG.RichTextArea", "/org/openvpms/web/echo/js/rta.js");
    static {
                WebRenderServlet.getServiceRegistry().remove(RICH_TEXT_SERVICE);
        WebRenderServlet.getServiceRegistry().add(RICH_TEXT_SERVICE);
    }

    public RichTextAreaPeer() {
        super();

I have done the BoundRichTextArea and RichTextArea so far, but the Peer class is taking the longest to get the rendering done right.. with styling.

I have added 

 case "set-cursor-position":
                    EPRTA.MessageProcessor.processSetCursorPosition(messagePartElement.childNodes[i]);
                    break;

and

EPRTA.MessageProcessor.processSetCursorPosition = function (setCursorPositionElement) {
    for (var item = setCursorPositionElement.firstChild; item; item = item.nextSibling) {
        var elementId = item.getAttribute("eid");
        var cursorPosition = item.getAttribute("cursorPosition");
        var textComponent = EchoDomPropertyStore.getPropertyValue(elementId, "component");
        var element = document.getElementById(elementId);
        textComponent.setCursorPosition(element, cursorPosition);
    }
},

but my Js is not great  - I had to expand the getComponent function as I wasnt sure it was available in context.
