i maybe found a bug in intboxes on mobile devices.

If u create and intbox with a maxlenth value, on desktop browsers it works like expected. But on mobile devices i can enter way more numbers then the maxlength value is (Its not working at all).

I know that maxlength doesnt exist for 'input type="number"', but on desktop a 'textbox type="text"' is generated, sadly im unable to see, what is generated on my mobile device. However, in addition, if u go in "desktop view" on your mobile device, u will also be able to enter charakters, that arent numbers.... Tested on Android: Chrome and Mozilla, and IPad: Safari.

you can simulate the mobile rendering e.g. in chrome (and other browsers) by enabling the mobile emulation mode in the developer tools:

and in fact it creates an input type="number" for a mobile device

Ah, yes thats true. But still, if u are on a Mobile Device and activate "Desctop View" you can enter charackters. And further i can also enter more then the maxlength value.

in my tests that's only try for a new ipad (running on ipadOS) which doesn't allow to identify whether it's a mobile or desktop device in a reasonable way. ZK already adapted the code to detect it as a mobile device even when it announces to be a desktop device ... not sure the opposite is correct.

in any case during the constraint validation the too long value is rejected correctly and an error message is displayed

related (conflicting) issues are ZK-4719 and ZK-4451, we can't have it both ways, thanks to apple

just tried this again with the latest ipadOS and ZK ... I didn't encounter the issue any longer
