exclude special characters from textfield

[rjanos]

Hello,

I am trying to create an editable comboBox which accepts only certain characters.
I tried to set maskRe as

maskRe: new RegExp("^[a-zA-Z1-9_ ]*$")

However in IE the special characters get through (#,$,etc). If I saw it right it is because the filterKeys method has this exit branch:
if(Ext.isIE && (e.isSpecialKey() || !cc)){
return;
}

before the maskRe validation.

Can somebody tell me how can I force the textfield to allow only these characters:
a-zA-Z1-9_ and space ?

thanks,
Janos

Try a '+' instead of a '*' at the end. * will match if it is present or if it is not.
