DBEdit does not refresh when linked to calcfield

[Renato Ricci]

Hello all..
Is there any way to make dbedit linked to a calcfield automatic get refreshed with dataset field value?
I know that with dbgrid, the collumn linked to calcfield is automaticaly refreshed.. How to do it dbedit?

Please see example attached..

PS: Example requires New RXLib because it uses TRxMemoryData(if you need: http://svn.code.sf.net/p/lazarus-ccr/svn/components/rx/trunk);

PS1: I already tried the same example with other ways to access db data(zeos and sqldb), ans the behavior is the same..

Any ideia?
Thanks,
Renato
