Hi Uncle Cheese or anyone else out there.
Just installed the ImageGallery which I downloaded directly from http://carlinowebdesign.com/

First I installed DataObjectManager (did all the .../dev/build/?flush=1 stuff), followed by SWFUpload Field and finally installed Image Gallery. I created an album, and everything seems to be fine, except for the fact that I cannot add any images to the album. Whenever I click the 'Add images to "RadioTaxis" ' button (that's the name of my album, I get the following:

[Warning] ViewableData_Customised::obj() 'DetailForm' was requested from the array data as an object but it's not an object. I can't cast it.
GET /rtg/admin/EditForm/field/GalleryItems/upload?album=3

Line 990 in /var/www/html/rtg/sapphire/core/ViewableData.php

981 			return $val;
982 		} else {
983 			return $this->obj->XML_val($fieldName, $args, $cache);
984 		}
985 	}
986 	
987 	function obj($fieldName, $args = null, $forceReturnObject = false) {
988 		if(isset($this->extraData[$fieldName])) {
989 			if(!is_object($this->extraData[$fieldName])) {
990 				user_error("ViewableData_Customised::obj() '$fieldName' was requested from the array data as an object but it's not an object.  I can't cast it.", E_USER_WARNING);
991 			}
992 			return $this->extraData[$fieldName];
993 		} else {
994 			return $this->obj->obj($fieldName, $args, $forceReturnObject);
995 		}
996 	}

Any ideas?

Hmmm....it seems the same files work well on another host without the problem I described above. Not sure what I need to change on the other server to rectify the problem...I'll investigate.

I have this problem, anyone got any ideas?

Make sure you're using the builds on the Silverstripe website, or better yet, the SVN channels. This sounds like a really dated bug.

I'm a SS rookie but i tried installing a fresh wamp server, a fresh silverstripe server and then add the dataobject_manager and the swfupload (and not the image_gallery) and then i still get the error when i try uploading a file under the files & images section of SS.

So i guess the issue lies there somewhere, anyway, any ideas would be helpful.

You're using the SVN checkout of DataObjectManager?

I have the same issue, tried everything i know - even searched the forum. No luck.

I have installed the three programs from you web - SWFupload, DataObjectManager and the ImageGallery.

It comes with wierd button for adding album and pictures, and the big error when trying to open the page in published site.

Hope you can come with a solution Uncle :-)

<% if Paginator.NextLink %>
<td id="ComplexTableField_Pagination_Next">
<a href="$Paginator.NextLink"><% _t('NEXT', 'Next') %><img src="cms/images/pagination/record-next.png" /></a>

This parts is an error, of which i cannot see?

What's the error?
