[ckan-dev] Reading error after adding a new field in Organization

[Qifeng.Bai at csiro.au]

Hi, there

I have been struggling into add a new field into "Organization" for a whole week. I have managed add a field "project_leader" into "organization'

I can use API method to retrieve this project and get the value of "project_leader".  However, when I use CKAN page: http://127.0.0.1:5000/organization/project6, it returns me "ValidationError: {'name': [u'Missing value']}"

Any comments are appreciated!

See below:

API method return correct value:

http://localhost:5000/api/3/action/organization_show?id=project6 .

It returns:
{
help: "Return the details of a organization. :param id: the id or name of the organization :type id: string :param include_datasets: include a list of the organization's datasets (optional, default: ``True``) :type id: boolean :rtype: dictionary .. note:: Only its first 1000 datasets are returned ",
success: true,
result: {

display_name: "project6",

}
}

use CKAN page: http://127.0.0.1:5000/organization/project6  returns error:
