Perhaps you could describe your situation a little bit more? Are you using a FlashIsland? Where exactly do you want these "database validations"? Are you calling a service from Flex?

If this is a FlashIsland, then your validation logic shouldn't be in Flex anyway. The FlashIsland should be a pure UI construct and shouldn't replicate UI elements that you can already create in Web Dynpro. The data should be bound to the Web Dynpro ABAP context. All logic and validatoins are performed back in Web Dynpro against the data in the context.

SAP's recommendation is that you shouldn't recreate any UI elements that you can do in Web Dynpro within the FlashIsland. Why do you need the input field to be in Flex? You should issue all your error messages from Web Dynpro for consistency.
