I have an external list, items in that list have a field that contains an url. I want to show this url as a link in sharepoint form. I found this example and defined in my Creator and Updater methods in BCS model:
<TypeDescriptor Name="description" DefaultDisplayName="Description" TypeName="System.String" CreatorField="true" > <Properties> <Property Name="SPCustomFieldType" Type="System.String">Url</Property> </Properties> </TypeDescriptor>
But this does not work, Item field is shown as simple TextBox form. If I add this TypeDescriptor to SpecificFinder Method on list creation(using Client Object Model) I get a strange "Application error" exception. Any ideas why this isn't working?
