Question

Image button in a cfwindow doesn't pass coordinates

Normally when you click on an image button inside a CFFORM, the coordinates are  passed to the form processor. This is a simple way to support multiple buttons  from a single form because you can use the presence of a coordinate to tell you  which button was pressed.

I couldn't figure out why this wasn't working inside a CFWINDOW and eventually I  stripped out all the extraneous code until I discovered that when the CFFORM is  inside a CFWINDOW, it no longer passes the coordinates. Is that documented? Can  anyone comment on that situation?

    Could you pls post your test case so we're all reading from the same page, as it were?

    Cheers.

    OK, here is it is (other than the 2 images) ...

    Calling page is

    <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">
    <html>
    <head>
    <meta http-equiv="Content-Type" content="text/html; charset=utf-8">
    <title>Untitled Document</title>
    </head>
    <body>
    <p><a href="javascript:ColdFusion.Window.show('EventUpdate');ColdFusion.navigate('TestImageButton2.cfm','EventUpdate');" >
    Click here to open the window</a></p>

    <cfwindow name="EventUpdate" modal="true" resizable="false" title="Test"
        width="550" height="550" x="500" y="150"
        bodyStyle="font-size:12px; font-family: verdana; background-color: ##dcefd2; color: black; text-align: left;"
        headerStyle="font-size:13px; font-weight:bold; font-family:Verdana; color: white; text-align:left;" >
        <cfajaximport tags="cfform, cfwindow" scriptsrc="/CFIDE/scripts">
        </cfwindow>

    </body>
    </html>

    Called Ajax processor:

    <cfdump var="#FORM#">

    <cfform>
        <cfinput name="Comment" size="75" required="no" />
        <INPUT TYPE="IMAGE" NAME="Save" SRC="MSave.png">
        <INPUT TYPE="IMAGE" NAME="Delete" SRC="MDelete.png">
        </cfform>

    Just click on the image and see what comes through. When similar code was run without the CFWINDOW, it provided the coordinates.

    Yeah, I ran your code and - unsurprisingly - saw the same thing you did.

    When one runs just TestImageButton2.cfm, <cfform> intercepts the form submit, running this event handler first: return _CF_checkCFForm_1(this).  However that one works.  When it's in a <cfwindow>, it runs this instead: return ColdFusion.Ajax.checkForm(this, _CF_checkCFForm_1,'EventUpdate_body') which seems bung to me.  WhyTF they mess with the form fields is beyond me.

    I'd raise a bug for this, and see if there's some way of doing what you want with JQuery or something similar instead.

    Sorry to not be able to be of any more help than that :-(
