Re: [Cforms-binding] Setting a constant value to a field using

[Jorge Davila <is...@nicaraguarealestate.com>]

Hello Antonio:

In my understanding of the process ... you "must" have a method,
constant or field in your java class that return the value that you
want.

"Factory is not set ..." is obtained because there is no field, constant
or method defined in your java class doing reference to the "desired
value".

P.D.: Te agradezco que me hayás puesto en contacto con este marco de
trabajo para desarrollo web y te pido disculpas (públicas) por no
haberme permitido la posibilidad de desarrollarme dentro de tu equipo de
trabajo.

There is the java attribute. In fact, I just get a working code to play
with this. And just tried to set a constant value. Not too much changes
after all. :-)

Please see my reply to Leszek in this thread to see how and why this failed.

Best Regards,
