Maxim/Sergey, any pointers?

1)For know we are not support execution of java script in visual editor.
To allow javascript we should switch off design mode, but know it's hard to do, because all selections events
processing throw nsISelectionController which can be obtained only if we switch mozilla in design mode.

Where is "design mode" turned on and off? So if I understand correctly ... taking the Mozilla renderer out of design mode turns off the propogation of nsISelectionController events?

org.jboss.tools.vpe.editor.mozilla.MozillaEditor.getEditor(), this method calls from VpeController.init();
To Disable design mode you should comment body of method org.jboss.tools.vpe.editor.mozilla.MozillaEditor.getEditor().
Also for **Preview** tab we using another instance of mozilla , which in browser mode and you can use preview mode, then you shouldn't
swicth off design mode.

2) possibly JavaScript that inserted into head node doesn't be executed automatically, because browser executes this scripts
when documents are loaded. When we insert it into DOM, document already loaded.

This sounds right, but if I can't execute javascript at all, I guess it doesn't matter? =)

For execution js i have mode following steps(Easy way):
1)create html page with following content
    <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
    <html>
        <head>
        </head>
        <body>
            <input type="button" onclick="alert('I am an alert box!!')" value="Display alert box" />
            <input type="button" onclick="document.write('Test');" value="Display alert box" />
        </body>
   </html>
2) open org.jboss.tools.vpe.html/templates/vpe-templates-html.xml file and add for tag with name="input" to copy attributes onclick attribute.
       It's should looks like this: <vpe:copy attrs="id,type,style,class,value,size,onclick" />
3) open page which was created in [1] in visual editor.
4) switch to preview tab, and click on submit button on page. JavaScript will be executed.

PS. Using of JavaScript in Visual Editor can strongly change the process handling, because we can modify dom using js, and using
xpcom, there then many questins how to map elements from source and visual part and others.

Very true.. Our problem is that the appcelerator platform uses javascript code to render widgets.. it's sounding more and more like it would be better to try and approach this using Rhino. I'd still like to fiddle with the design mode to see what I can accomplish though, any pointers to source code?

I think it's better to use in test purposes preview tab for testing js, in such way it's takes minimal changes.
