The ValidateLongRange tag registers a LongRangeValidator instance on
the component associated with the enclosing tag. This tag can be used
to validate user input when the expected value is a long integer that
is greater than or less than another value or is between two values of
the same data type.
Example:
<h:inputText id="withdraw" value="#{accountBean.withdraw.amount}">
<f:validateLongRange minimum="20" maximum="1000" />
</h:inputText>
<h:message for="withdraw" />
HTML Output
<input id="form:withdraw" name="form:withdraw" type="text" value="5"/>
"withdraw": Specified attribute is not between the expected values of 20 and 1000.
When
the form is submitted with the value 5 in the input field, the JSF
framework will convert and validate the user input to determine if the
value is between the minimum and maximum values defined by the
validateLongRange tag. Since the input is not valid, the JSF framework
creates a validation message that can be displayed using the h:message
or h:messages tags. |
