Edit -- Im posting as a reply as the Edit of my post is failing.

Ive pointed the 4.5 release source at my database (im using 4.5.2) and in UpdateInterface call in the GenericProprty control code behind, _dataTypeDefinitions is populated, and therefore so is the ddlTypes dropdown. I will dig a little deeper into the genericproperty.js and diff the versions to see if can spot anything.

Edit 2 --

Ok, if i change a document types Default Template, under the info tab and then save, the ddlTypes drop down is populated. I can then add new properties to that doc type until i navigate away from that document type and back. After navigation the drop down list is empty.

This only works when first creating a document type. Trying the same again (changing the Default Template and saving) throws this expection in the right hand side frame:

Should I post this as a bug? I can just work directly against the database cmsPropertyType table for the time been but that wouldnt be cricket if this was production. Im currently just hacking around at the minute.

Edit 3 --

The above method of changing the Default Template and saving works every time, as long as no previous generic properties are assigned to that datatype. The save is failing only when there is at least one. The above error must be coming from the fact its trying to save existing generic properties where the ddlTypes dropdown is empty, and causing the parse exception.

Anyone?

Thanks.

Hi Benjamin

Is it a clean installation of 4.5.2 or have you upgraded from a previous version?

What permissions have you given the network service and the iusr?

Are you running ASP.NET 4 and integrated mode in the application pool?

I am getting the same error :(

Hi Aymeric

Sorry for the late reply - I'm wondering if you could share some details about your setup? Basically the same information I've asked for in my previous answer to this post.

Cheers,
Jan

Hi Jan

I have the same problem just on a 4.7.2 clean install.

I know this happens when you install Autofac with WebForms integration in an Umbraco project.  When Umbraco loads the document type editor control (GenericProperty.ascx), its public "DataTypeDefinitions" property gets overwritten by Autofac with an empty array.  Hence the select box usually containing the document types turns up empty.

To get around this problem, use Attributed Injection

Thanx James.. That solved my problem.
