TextFieldInputMode supports the following numeric input modes but none of them restrict input to just numbers.

PhoneNumber
NumbersAndPunctuation
NumericPassword
Pin

This has got to be an extremely common use-case.  Is there a work around besides filtering input as it's typed?

Not that I don't also miss that option, but note that some might also say they'd like "numbers and decimal place only" or "numbers and plus or minus", and so on.

Also, there's probably ways of using copy/paste to bypass the keyboard restrictions.

I short, I think filtering is probably what's required in any event... The custom keyboards are just a convenience for the user, but perhaps not a mechanism developers should rely on to restrict the input.

That could easily be fixed by designing the options to be OR'able together like so:

TextFieldInputMode.Numeric | TextFieldInputMode.Punctionation
TextFieldInputMode.Numeric | TextFieldInputMode.Plus | TextFieldInputMode.Minus
TextFieldInputMode.Numeric | TextFieldInputMode.Decimal
TextFieldInputMode.Numeric | TextFieldInputMode.Password

I hve also tried the nummericandpunctuation and on the latest Z10 release using 1673 (10.0.9.), my app still accepts the full keyboard.

This is true... the NumbersAndPunctuation keyboard doesn't prevent text entry, it just starts off on the numeric version of that as a convenience to the user. Text filtering in some fashion is still required, or a custom data entry keyboard, at least for now.

I did that using RegExp

Here is a JS function:

    function numericOnly (textin) { // allow users to use numbers only
                 
         var m_strOut = new String (textin);
         m_strOut = m_strOut.replace(/[^\d.]/g,'');
         
         return m_strOut;
                             
    } // end numericOnly

 and call once TextChanging signal is emitted:

			                onTextChanging: {
			                    text = numericOnly(text)

			                }

 That should work.
