Re: [Cppcms-users] cppcms::widgets::text::set() always returns true

[Artyom B. <art...@ya...>]

Yes there is a reason behind that.

The policy is if set() is false that accessing value() would throw an exception.

Blank text is still a valid text the empty string is still a text - i.e. you take value() and it is valid, on the other hand if there is no number or there is no uploaded file, than  there is no reasonable value() and than you must check the set() properly.

 This make sense to me:
 cppcms::widgets::numeric::set() returns false if
 users leave it bank.
 
 However, cppcms::widgets::text::set() always returns true
 regardless of
 users leaving it blank or entering characters in that
 widget. Is there
 any special reason why cppcms::widgets::text::set() behave
 so? Why is
 cppcms::widgets::text::set() not designed to return false
 instead if
 users leave it blank?
