RTC is not synchronized with new created table fields

Hi there, long ago,
My issue is the following;
I add for instance the field 50000 in the table 18, I save and compile. No prob.
If I create a new page without anything inside but based on the table 18, I got the error message:
The supplied field name 50000 cannot be found in the table 18.
MDN 2009 R2 on SQL /WIN 2008.
The services were restarted. The SQL was restarded. But still the RTC seems to ignore the object designer changes.
Please somebody have an idea?
Tks
