---------------------------------------
Resolution: Won't Fix
> Exceptions when setting properties to null (specific types only)
> ----------------------------------------------------------------
>
> Key: BEANUTILS-276
> URL: https://issues.apache.org/jira/browse/BEANUTILS-276
> Project: Commons BeanUtils
> Issue Type: Bug
> Components: ConvertUtils & Converters
> Affects Versions: 1.7.0
> Environment: java 1.4.2, 1.5.0
> Reporter: David Birch
>
> for the following types attempting to set a property to null using
> BeanUtils.setProperty(java.lang.Object, java.lang.String, java.lang.Object)
> will result in an Exception
> java.math.BigDecimal
> java.math.BigInteger
> java.net.URL
> java.io.File
> java.sql.Date
> java.sql.Time
> java.sql.Timestamp
> all primitive wrappers work fine, as does java.util.Date
> sample stacktrace is
> Failed Set empty [bigDecimal1]
> org.apache.commons.beanutils.ConversionException: No value specified
> at
> org.apache.commons.beanutils.converters.BigDecimalConverter.convert(BigDecimalConverter.java:103)
> at
> org.apache.commons.beanutils.ConvertUtilsBean.convert(ConvertUtilsBean.java:428)
> at
> org.apache.commons.beanutils.BeanUtilsBean.setProperty(BeanUtilsBean.java:1002)

> org.apache.commons.beanutils.BeanUtils.setProperty(BeanUtils.java:313)
> at
> com.marsh.ste.testing.steps.DataStepUT.testChanges(DataStepUT.java:52)
> The converter classes seem to sort of have an option to handle null inputs by
> returning a default value - from BigDecimalConverter.convert()
> if (value == null) {
> if (useDefault) {
> return (defaultValue);
> } else {
> throw new ConversionException("No value specified");
> }
> }
> though i am not totally sure, might be better to fix this in the
> BeanUtilsBean.setProperty method, add some other cases - block starting line
> 1001
> if ((value instanceof String) || (value == null)) {
> newValue = getConvertUtils().convert((String) value, type);
> } else if (value instanceof String[]) {
> newValue = getConvertUtils().convert(((String[]) value)[0],
> type);
> } else if (getConvertUtils().lookup(value.getClass()) != null) {
> newValue = getConvertUtils().convert(value.toString(), type);
> } else {
> newValue = value;
> }
> cheers
