Re: [Cppcms-users] Setting field value after form.load() still fails validation

[<ele...@ex...>]

It's not a default value.

The widget can either write an Int or YYYY-MM-DD in the widget.

my overloaded form.load() uses regex to see if its an Int or Date. If it's
a date, it converts it to an Int based on some rules.

The intention was to convert Date into Int before validation runs. The
field will then be validated as if it's an Int.

I simply had to set num.valid(true) after the conversion to Int.

My main point is that widgets::numeric::load silently validates the form,
when validation should be done when validate() is called.

Why wouldn't you use regex_field widget or derive your own widget from the test widget?
It would be more correct approach, you try to change the function of numeric widget
and it is bad idea.

I didnt use regex_field because I wanted the interface of numeric and also
its  low, high etc functions/

regex_field::value() would return a string thats either an int or date. I
didn't think that's a good idea.

I didn't think about deriving from numeric<int>, and overloading load(). I
think that's a better approach than overloading form::load(). Thanks.
