I need to create a deployable site page that uses various BDC Web Parts to display information from a external content type. The web part must retrieve the query value from a QueryString Filter web part or similar.
I can build a page to do with using the in-browser editor to place and connect the parts, but this is not suitable for the business deployment mechanisms, so I must use Visual Studio.
I can create the page containing the web parts, but I can't work out how to connect them. I tried copying the markup of a page built up in the way mentioned previously as a template item, and deploying that, but it gives me the following error when I navigate to the page:
Description: An error occurred during the parsing of a resource required to service this request. Please review the following specific parse error details and modify your source file appropriately.
Parser Error Message: Cannot create an object of type 'Microsoft.BusinessData.MetadataModel.IEntity' from its string representation '' for the 'SelectedConsumerEntity' property.
Source Error:

Can anyone shed some light on what I need to do here?
