Description

BeanUtils.populate throws an IllegalArgumentException when setting an indexed
String property as an array.

For example:

public class TestBean {
private String stringIndexed[] =

{ "String 0", "String 1", "String 2", "String 3", "String 4" }

;

public String[] getStringIndexed()

{ return (this.stringIndexed); }

public void setStringIndexed(String value[])

{ this.stringIndexed = value; }

public String getStringIndexed(int index)

{ return (stringIndexed[index]); }

public void setStringIndexed(int index, String value)

{ stringIndexed[index] = value; }
}

. . .

public class BeanUtilsTestCase extends TestCase {
. . .
public void testPopulateIndexedProperty2 {
// verify populate as String array.
Map aMap = new HashMap();

String[] compArray = new String[]
{"STRIDX 0", "STRIDX 1", "STRIDX 2", "STRIDX 3"};

aMap.put("stringIndexed", comp);

BeanUtils.populate(bean, aMap); // throws IllegalArgumentException!!!
}
}

I believe this should work because TestBean has the array setter method.
public void setStringIndexed(String value[])

Note, if I remove just the indexed setter it works!
/* public void setStringIndexed(int index, String value) { stringIndexed[index] = value; }
