hello all,
i need help in using the <bean:define> tag. I had first define a
bean to hold a String ArrayList which is to be used in a <html:select>
tag. however, this code fails to work and complains abt a
NullPointerException. And btw, can someone explains to me what's the
difference between scope and toScope? thanks
<bean:define id="travelPeriodList" name="newsletterForm"
property="travelDaysList"/>
<html:select property="targetDuration" size="0" value="">
<html:options collection="travelPeriodList" property="value"
labelProperty="label"/>
</html:select>
here's the exception:
java.lang.NullPointerException
