exception on queryForList with list of Enums

I am passing queryForList an ArrayList of Status, which is an Enum I
defined. I have registered a typeHandler for Status, as previously
discussed today on the list. The typeHandler works when querying for a
single object.

However, when querying for list, it gives the following exception: (See
below the stacktrace for diagnostics & question)

java.lang.StringIndexOutOfBoundsException: String index out of range: -2
	at java.lang.String.substring(String.java:1768)
	at com.ibatis.common.beans.GenericProbe.getObject(GenericProbe.java:55)

	at
com.ibatis.sqlmap.engine.impl.SqlMapClientImpl.queryForList(SqlMapClientImpl.java:78)



The line of code (com.ibatis.common.beans.GenericProbe.java:55) is:

      return ((List)object).get(new
Integer(name.substring(1,name.indexOf(END_INDEX))).intValue());

Here are the objects according to my debugger at this line:

object: java.lang.Object = {java.util.Arrays$ArrayList@1516} size = 1
[0] = {com.foo.beans.Deployment$Status$6@1526}"READY"
name: java.lang.String = {java.lang.String@1517}"status"

Clearly, "READY" does not contain END_INDEX, which is "]". "READY" is a
Deployment$Status value.

Where is the bug?

Thanks

Re: exception on queryForList with list of Enums

Agh, confused myself.

Let me clarify: the exception happens if I call queryForList with a
List<Enum> as the parameter. If I call queryForList with an Enum as the
parameter, no problem.
