Hi,
I'm building a report where the data is coming from a WCF Data Service.
I've therefore taken the approach outlined in this thread - http://www.telerik.com/community/forums/reporting/telerik-reporting/getting-data-from-web-service.aspx
In my report class I've added reference to the WCF Service and then implemented an extension - giving me a method that gets the data from the actual WCF service and returns an enumerable of the datatype I need to put into a table in the report. My new method is called "GetInvoicesDueThisMonth"
I've then added an ObjectDataSource from the toolbox and set it up in exactly the same way as the thread above - with the DataSource being the WCF service client class and the DataMember being the new extension method I implemented.
Next I set the DataSource of the Report to be the ObjectDataSource I added from the toolbox.
Finally I clicked on the Table Wizard from the toolbox and when I select my ObjectDataSource from the "Current Data Sources" - it throws back an error "Method GetInvoicesDueThisMonth() Not found."
I've attached two screenshots - the first showing the method implemented in the service extension and the second showing the error I'm getting... I've obviously had to blackout parts that I can't show.
Any idea how to resolve this and what I could be doing wrong?

I've just realised that exactly the same problem happens in the sample code I've downloaded from the link I previously mentioned.... see the attached screenshot.
How do I resolve this?

Is this related to the following comment in this article? - http://blogs.telerik.com/telerikreportingteam/posts/10-10-22/using-telerik-reporting-with-wcf-ria-services.aspx
"Note: Currently the Report Designer can't get the schema of the data source because of WCF RIA services' peculiarities. Thus be aware that the available wizards and Data Explorer would not be populated with data source fields and both Previews would not work."
If so, would you care to explain how we get around this and how the example code was therefore actually built?

Hello Chris,
Peter

In order to have design time support our suggestion is to use a dummy datasource (objects) that replicate the WCF service schema.

Hi, thought I should update on this... because I didn't really need actual 'design time' support, instead of using a dummy datasource I just added a blank table onto the report (not using the wizard).
Then, once I'd setup my datasource to be the ObjectDataSource, I just typed straight into the table cell.. for example if I knew the return type of service extension method had an attribute 'ABC' and I wanted that in the first column of the table, I typed "=Fields.ABC" into the table cell. This then appears as [=Fields.ABC] and when run works perfectly.
