ERROR: spry:region or spry:detailregion attribute has no data set!

Question

here's the basics...
i'm running fusebox for php (if that makes any difference)
i'm also reusing the same gallery for multiple fuseactions,
and using my circuit.xml file to set the var $gallery
depending on which fuseaction has been called.
the photos already exist in a database and full size and
thumbs have already been created by imagemagick
i plan on writing a script that uses imagemagick to get the
dimensions of the imagefiles and saves them to four respective new
columns in my db table (so i hope the problem isn't related to the
height attributes not being set in my xml.... let's hope it's
somthing else, ok?)
i'm creating my datasets like this
quote:
var dsGallery = new Spry.Data.XMLDataSet("/index.php",
"gallery", { method: "POST", postData: "do=m.get<?php echo
$gallery ?>Gallery", headers: { "Content-Type": "text/xml" });
var dsPhotos = new Spry.Data.XMLDataSet("/index.php",
"gallery/photos/photo", { method: "POST", postData:
"do=m.get<?php echo $gallery ?>Gallery", headers: {
"Content-Type": "text/xml"});
the output xml is perfect... here's an example
http://www.inkincnewyork.com/index.php?do=m.getFlashGallery
since i'm reusing the gallery, and have no need for the
dsGalleries related functionality i did this.
using the long way of referencing each piece of data, just to
make sure it's all kosher
quote:
<div id="thumbnails" spry:region="dsPhotos dsGallery">
<div spry:repeat="dsPhotos"
onclick="HandleThumbnailClick('{ds_RowID}');"
onmouseover="GrowThumbnail(this.firstChild,
'{dsPhoto::photo/@thumbwidth}', '{dsPhoto::photo/@thumbheight}');"
onmouseout="ShrinkThumbnail(this.firstChild);"><img
id="tn{ds_RowID}" alt="thumbnail for {dsPhoto::photo/@thumbpath}"
src="{dsGallery::thumbnail/@base}{dsPhoto::photo/@thumbpath}"
width="24" height="24" style="left: 0px; right: 0px;"
/></div>
<p class="ClearAll"></p>
</div>
but i am now getting this error
spry:region or spry:detailregion attribute has no data set!
for each XMLDataSet
anyone have any ideas?

Answer 1

A few things I noticed when looking at your sample source
above:
The "Content-Type" should be the type for the post data, not
what you expect to get back. So in your case, you should be using:
"Content-Type": "application/x-www-form-urlencoded";
which is the default type so you don't really have to pass it
to the constructor unless you are posting something other than that
type.
Next, your {ds_RowID} data references are missing the data
set prefix. If you use more than one data set for a given region,
you need to use the prefix to make sure you are getting the
ds_RowID from the correct data set.
The error: "spry:region or spry:detailregion attribute has no
data set!" tells me that the data sets are not defined at the time
Spry first processes the region. Are your data sets being created
in a script tag in the head? Or are you creating them in some
function that gets fired off at a specific time?
