warning if a required field is left empty

Hi,

I have an xform with several required fields. If the user leaves one
of them blank and presses the submit button, nothing happens. How
could I add a warning message saying "You didn't fill all the required
fields." ? I don't want to detail which fields are missing, I just
want a general warning.

Thanks,

Laszlo

Re: warning if a required field is left empty

Hi Laszlo,

Easiest thing is to add an xf:message handler on the
"xforms-submit-error" event.

Regards,

Mark

Hi,

Is it possible to resize an image when visualizing it? I want to
upload photos, and they might be really big. An optimal solution would
be to show just a thumbnail, and when the user clicks on it, show the
image in full size.

Thanks,

Laszlo

Not in standard XForms, AFAIK.

Hi,

Then I must find an alternative solution. What do you think of this one?

For producing xforms, I use Java Server Pages. The instance that I
want to visualize is loaded from a database. If it's not possible in
XForms, then I should replace the image visualization part with normal
XHTML. The problem is that I cannot get the image URLs from the XML
instance with "ref" in XHTML, I guess. So should I write a JSP code
(or bean) to extract the URLs from the XML instance, and use these
URLs to produce the image visualization with thumbnails?

If you have a better idea, plase let me know.

Thanks,

Laszlo

Output notation for attributes

Hello,

<xf:output> can be used to dynamically output text, binary content or 
elements but there is no notation for attributes...

I think it wouldn't be very difficult to add something like 
attr="{xpath_expr}" just like in XSLT !?

What do you think about that ?

Re: treating (multiple) attached images

Hi Jabba,

You could resize the output with CSS, couldn't you?

Re: Output notation for attributes

Some implementations, in particular Orbeon Forms, support such  
Attribute Value Template (AVT) notation.

Yes, that's invaluable

My problem is that XForms is a hosted language, and you aren't really  
allowed to define the content of other languages' attributes.

Another way of achieving the same result (which would be allowed) would be  
to have a special instance that represented the current document:

     <body class="default">
     ...
	<select1 ref="document()/body <at> class">
	<label>Style:</label>
	   <item>
	      <label>Default</label><value>default</value>
	   </item>
	   <item>
	      <label>Night</label><value>night</value>
	   </item>
	   <item>
	      <label>Black/White</label><value>monochrome</value>
	   </item>
	   <item>
	      <label>Big fonts</label><value>big</value>
	   </item>
	</select1>
