Validate double number

[rchiu5hk]

Dear all,

I have below code for inputting number of hours. But I does not know why when I input "11A" or "88**(((**%" and then click submit, it will pass the validation but without saving.

Code: Select all

<p:inputText required="true" requiredMessage="#{esMessage['WARN.ESTTC3S5']}" id="txtHours" value="#{courseInfo.regHours}" style="width:500px"
converter="javax.faces.Double" converterMessage="#{esMessage['WARN.ESTTC3S5.DigitOnly']}">

<f:convertNumber pattern="#0.00" />

</p:inputText>

Why don't you make this way easier on yourself and use p:inputNumber like...

Code: Select all

<p:inputNumber id="txtHours" required="true" value="#{courseInfo.regHours}" decimalPlaces="0" minValue="0" maxValue="24"/>

In the example above it only take integer numbers and has a value of 0 to 24. You can obviously increase if you need more than 24 hours but the component won't even allow letters or special symbols to be entered and it will convert to a Double or whatever Number you have on the back end.
