File/media picker stopped working


I have a site that has recently been upgraded to 7.5 and all of a sudden the "file/media picker" stopped working.

When trying to select a file for my Url-property its not marked green as usual(to indicate which file is choosen) and if i click ok the url-field is left blank. The same happends if i try to use the insert image button in the html-editor. We also used to be able to drag and drop a file from the media dialog but this also seems broken. I only get a link instead of a image tag.

I can see that the image gets selected. It gets a class called dijitTreeRowSelected but on mouseup it gets deselected again.

I have been trying to find a reason for this problem but i am running out of ideas. Anyone out there that has had any simular problems?

Hi Andreas!

Is your content type for files inherriting from ImageData or implementing IContentImage? If not, that would at least explain the drag and drop issue.

Yes, my class signature looks like:

    [ContentType(GUID = "7B598308-DA7C-47AE-AB66-EF12EE745AD9")]
    [MediaDescriptor(ExtensionString = "jpg,jpeg,jpe,ico,gif,bmp,png")]
    public class ImageFile : GenericMedia, IContentImage

GenericMedia is a base class that inherits from MediaData.

I used to inherit directly from ImageData but since i wanted a base class with common properties i rearranged it this way. This was done 2-3 weeks ago and has been running fine until a couple of days ago also.

The media i tested with are of type ImageFile.

It seems to work when i switch back to inheriting from ImageData... Just implementing IContentImage dosent seem to be enough.

I tried using the code you posted above inheriting from the GenericMedia class in the Alloy templates and it works as expexted, I can select files of this type in a file selector and drag and drop instances to the html editor. So right now, I'm not sure how to reproduce your issue.

I will hava look if i can reproduce it in the Alloy project myself as soon as i get a few minutes to spare :)
