DataSource goes lost

WEB TMS WEB Core
1

Hi,

I have the problem, that web core looses the datasource setup, if I did it in design-time. Until now I can not say, where / when it is caused, but I had it in two times today, that all DataSource links from TWebDBEdits and TWebDBLabels and TWebDBLookUpComboBox (DataSource and ListSource) gone.

How to reproduce?
Cannot be seen for example in demo Demo\Basics\DBGrid

Yesterday, I worked on the server side. I was not able to reproduce it. Let me check, if I made a mistake. Today I will work on both sides. I will give a feedback.
