Hi Johan

Not that I know anything about what is the cause of this but I'm wondering if you have seen the cropup package by Niels Kühnel? It's really a fine piece of work and I think that your editors will love it.

Perhaps it would be easier to simply switch?

Check it out here http://our.umbraco.org/projects/website-utilities/eksponent-cropup

Cheers, Jan

are they with 2 different alias?

@Jan: I've thought about it and am leaning on gonig down that road. But it's a pretty big site and the ocd side of me is going to want to change all crops to CropUp for the sake of consistency.

@Ali: Yup, and none of their aliases is "ImageCropper"

Doh! Using CropUp resulted in a similar error message:

Multiple controls with the same ID 'Container' were found. FindControl requires that controls have unique IDs.

Solving it by using both croppers now :(. Can anyone else get this to work? This must be a bug.

Hi Johan

Coiuld you perhaps post a screendump with your document types setup?

Have you tried giving the properties a totally different alias just to make sure that there are no duplicates? Coming to think about this error usually happening when inheriting document types etc.

Looking forward to hearing from you.

/Jan

I created a new clean document type in the root and added the following properties:

Still the same error :(

This is by design, not a bug. When you create your own datatype of type 'image cropper', you'll see that the newly created datatype has the same 'unique' id as the native 'image cropper'. Since the controle are referenced by the guid, you can't use them on the same page.

This goes for all datatypes.

is working on a reply...
