Error while creating VCL Application, using Data Abstract Template

Data Abstract
1

Hi there,

I’m looking for a framework to work with OData (Server) with Delphi.
I’ve started working with Data Abstract, and I’m using the component’s default template.

Here is what I’m doing:

  1. File > New > Other
  2. VCL Application.
  3. Client and a New Custom Data Abstract Server
  4. My database is succesfully conected.
  5. I’m selecting only one table from my DB, for testing purposes.
  6. Checked the option <Add support for OData Publishing. Unchecked . The rest leaved as default.

After a few seconds of processing, I’ve got an error.
<Error: ServerSchema was not processed due to internal exception: System.ArgumentNullException: Value cannot be null. Parameter name: s at System.IO.StringReader…ctor(String s) at System.Xml.XmlDocument.LoadXml(Strin…:>

I know that there is a topic for this error, but it is not finished. There isn’t an answer.

Could you help?

As I’m a little smart. After reading your question, I’ve tried with another driver. With Firedac / ORACLE, and everything went fine.
