Hi
I'm not very experienced with SilverStripe having inherited the site from a previous developer so please forgive the noobyness.

I have installed the jQuery Slideshow module which works fine on some pages but causes other pages to give the following error when selected for editing i the admin page.

"Unknown column 'HomePage.ID' in 'where clause'
IN POST /admin/getitem?ID=1&ajax=1
Line 525 in /home/soundsma/public_html/sapphire/core/model/MySQLDatabase.php"

This is preceded by a query string.

In _config.php I have:

"//enable slideshow on all pages
DataObject::add_extension('Page', 'Slideshow');"

If I comment out the above, the errors vanish.

The other thing I notice is that the error occurs on pages that dont use mysite/code/Page.php but I'm not sure how this relates to the 'Page' parameter in the above. They have their own files eg: mysite/code/Project.php and mysite/code/Homepage.php

I'm just guessing beyond here so any help would be much appreciated.

many thanks

Thanks for the suggestion.
I now have this in _config.php:

//enable slideshow on all pages
DataObject::add_extension('Page', 'Slideshow');
//enable slideshow on all Homepage
DataObject::add_extension('HomePage', 'Slideshow');

Is that what you meant?

I still get the error though

Hi
That pesky dev/build again! I do forget it sometimes but this time it made no difference I'm afraid.
I still get an error when I try to edit the homepage in admin.
On other pages that use Page.ss the slideshow works fine, it appears to be a problem on pages that dont use Page.ss such as HomePage.ss. This may not be related but it is my observation.

I have attached a txt file with the whole error message in the hope that it might mean something to you.

Again, many thanks for your help, your time is much appreciated.

Hi
I inherited the site from the developer who built it so I didn't personally create any of the pages.
Maybe if you can tell me what I need to check I could have a look.

Alternatively would it make sense for me to set up ftp access for you so you can have a look yourself.

Many thanks for your time, its much appreciated.
