Xpages phone number

Question

In my application I have a field which have to store a phone number. The field must not allow characters but only numbers. The problem is that the format is something like:

0752344234

and if I add something like this, Xpages will save the field as: 752344234 without the 0.

Question: What method can I use to add the 0 in front of the numbers withouth using a string type field?

Answer 1

Use the validateConstraint validator:

<xp:inputText
    id="inputText1"
    value="..."
    disableClientSideValidation="true">
    <xp:this.validators>
        <xp:validateConstraint message="Please enter only digits for phone number">
            <xp:this.regex><![CDATA[^[0-9]*$]]></xp:this.regex>
        </xp:validateConstraint>
    </xp:this.validators>
</xp:inputText>

The regular expression ^[0-9]*$ accepts any number of digits and an empty string. If you want at least one digit then replace * by +.

You don't need to set the input text field as required.

You can decide where you'd like the validation message to appear. Set option disableClientSideValidation="false" to show message as a dialog box on client side or disableClientSideValidation="true" to put the message into xp:message/xp:messages control.
