I don't use any component and yes I am trying to bind directly to a
Hibernate entity.
I think the problem in line 1004 in
org.apache.commons.beanutils.BeanUtilsBean.java
else if (value instanceof String[]) {
newValue = getConvertUtils().convert(((String[]) value)[0],
type.getComponentType());
The bind actually happens but the set is populated only with 1 value
regardless of the array size. I think that is because of ((String[])
value)[0]
What do you think?
BISO
org.apache.commons.beanutils.BeanUtilsBean.java
------------------------------
976 if (type.isArray() && (index < 0)) { // Scalar value into array
if (value == null) {
String values[] = new String[1];
values[0] = (String) value;
newValue = getConvertUtils().convert((String[]) values,
type);
} else if (value instanceof String) {
String values[] = new String[1];
values[0] = (String) value;
newValue = getConvertUtils().convert((String[]) values,
type);
} else if (value instanceof String[]) {
newValue = getConvertUtils().convert((String[]) value,
type);
} else {
newValue = value;
}
} else if (type.isArray()) { // Indexed value into array
if (value instanceof String) {
newValue = getConvertUtils().convert((String) value,
type.getComponentType());
} else if (value instanceof String[]) {
1004 newValue = getConvertUtils().convert(((String[])
value)[0],
type.getComponentType());
} else {
newValue = value;
}
} else { // Value into scalar
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;
}
}

What type of component are you using to "edit" your set? Are you
trying to bind directly to a Hibernate entity with a Set property?
