Email address not passing - virtual attribute problem?

[Florin Wach]

Hoi Cheri,

as far as I know, the virtual attributes are processed each time you access them. (unlike the object builder in test modes, that touches every virtual attribute in the test screen).

If you need to access the result of a virtual attribute from another one use the following statement:

DATA: value   TYPE C. "or whatever
swc_get_property self 'VirtualAttribB' value.

Make sure, that VirtualAttribB doesn't call this virt. attribute again to avoid endless loops.

Best wishes,
Florin
