Hi Aaron, Thanks for jumping in.

Yeah, I think ultimately it’s esoteric, as advertised, and just not very interesting.

What I’m talking about here is the validation that happens just _prior_ to that—what Chuck calls “Automatic EOF Property Validation” on p.143 of Practical WebObjects. My example triggers that because there are model attributes with allowsNull = N. > Obviously if it is just a method on the page it cannot “discover” validation > methods to call because it doesn’t know the underlying logic or how to get to > the EO that is covered by the custom WOComponent method.

My observation is just that changing this: <wo:text value="$^value"></wo:text> to this: <wo:text value="$value"></wo:text> (even when paired with a setValue() method that calls setValueForBinding(value, "value”)) seems to _bypass_ the “Automatic EOF Property Validation” that happens in the first case above. I’m almost boring myself talking about it now. I doubt there’s any bug, unless it’s in my code, I just thought someone else may have noted the inconsistency themselves, and could perhaps offer a workaround or something. But it’s not a big deal. -- Paul Hoadley http://logicsquad.net/ https://www.linkedin.com/company/logic-squad/
