[beanutils] Problem with indexed properties
Someone on struts-user got tripped up by what I thought was a bean that
didn't conform to the spec, but then I learned that for an indexed property,
you can have four accessors, such as:
String[] getProp()
String getProp( int )
void setProp( String[] )
void setProp( int, String )
The struts user threads are:
http://marc.theaimsgroup.com/?t=110644250000001&r=1&w=2
http://marc.theaimsgroup.com/?t=110666379700006&r=1&w=2
I can reproduce the 'argument type mismatch' error under both Windows and
HP-UX, with JDK 1.4.2 or 1.5.0, with this code:
BeanUtilsBean beanUtilsBean = new BeanUtilsBean(
new ConvertUtilsBean(),
new PropertyUtilsBean());
IndexedBean bean = new IndexedBean();
String[] newValue = new String[] { "dog", "cat", "bird" };
beanUtilsBean.setProperty(bean, "prop", newValue );
(IndexedBean just has the four methods shown above.)
test.bean:
[echo] Running BeanUtils tests ...
[java] [ERROR] PropertyUtils - Method invocation failed.
<java.lang.IllegalArgumentException: argument type
mismatch>java.lang.IllegalArgumentException: argument type mismatch
The additional test and bean are attached to bug 28358.
http://issues.apache.org/bugzilla/show_bug.cgi?id=28358
It was originally reported as a JVM problem, but even if the code would work
under 1.3.1, that isn't going to help those of us who have long since moved
up to 1.4 and 1.5.
