Validating cancel true

z3c.form’s field widget validators address these shortcomings.

does not automatically invoke validators on every form submit.

This is actually a good thing, because it makes it much easier to decide when validation makes sense (e.g. We have already seen the most common pattern for invoking validation in our handler for the “order” button: call, but before the possible premature return in case of validation errors.

This method sets up event handlers for submit, focus, keyup, blur and click to trigger validation of the entire form or individual elements.

Each one can be disabled, see the onxxx options (onsubmit, onfocusout, onkeyup, onclick).

This is no problem if the interface exists only for the form, but could be a problem if it is used in other contexts as well.

Second, if we want to re-use a validator for multiple forms, we would need to modify multiple schemata.

I have a routine to handle textbox.validating, and I have the form setup so the Cancel button is the Cancel button. I am going to start a new thread - calling it a bug and see what happens. Down (Down Arrow) and some how (and I never figured this one out) the next control in the tab order, regardless of the Tab Stop property, got focus.

WHen the user clicks on the cancel button, the textbox.validating is being called. Darin *** Sent via Developersdex I know that, but the problem is when the user clicks EXIT, the textbox.validating event is called BEFORE the cancel.click is done, so the textbox is being validated. I reprogrammed the device to only send the CR and now the problem is solved. Does look like a bug or perhaps and Undocumented System Feature!

The valid values for Widget Validator Discriminators are: exceptions to indicate a validation problem.
