Keyword: Redraw or replace text dynamically

I have a textWidget which has about 20 chars displayed.
I would like certain substring to be replaced or redisplayed.
The textWidget is created as following:

        XtSetArg(textArgs[n],XtNeditType,XttextEdit);n++;
        XtSetArg(textArgs[n],XtNtextSink,XtAsciiSinkCreate(box,NULL,0));
                n++;
        source = XtStringSourceCreate(box,srcArgs,XtNumber(srcArgs));
        XtSetArg(textArgs[n],XtNtextSource,source);n++;
        XtSetArg(textArgs[n],XtNwidth,400);n++;
        XtSetArg(textArgs[n],XtNheight,400);n++;

        textWidget = XtCreateManagedWidget("text",textWidgetClass,box,
		textArgs,n);

I got the following message when the textWidget is realized:

	X Toolkit Warning: No type converter registered for 'String'
	to 'EditMode' conversion.

When I call to

	XtTextInvalidate(textWidget,1,10);
I got bus error:
	Bus error (core dumped)

	XtTextReplace(textWidget,1,10,&text);
	XtTextEnableRedisplay(textWidget);
    where text is as following:
		XtTextBlock text;
		text.ptr = newString;
	        text.firstPos = 1;
        	text.length = 10;

Am I doing anything wrong here?
Thank you in advance for you help!!!
