I believe I am getting the same bug.
I am getting:
Caused by: java.lang.IndexOutOfBoundsException: Index: 2, Size: 0
at java.util.ArrayList.RangeCheck(ArrayList.java:508)
at java.util.ArrayList.get(ArrayList.java:320)
at test.IndexedForm.getParameter(IndexedForm.java:28)
... 46 more
running jakarta-struts-1.1-b2 on Apache Tomcat/4.1.12 JSDK=1.4.1_01-b01
Trying to do this simple indexed ArrayList I built on top of the struts-example webapp. See source code attached.
What are the alternatives here. Go back to JDK 1.3.1 ?
Thank you so much,
Leo

Subject: RE: IndexOutOfBounds error, Struts 1.1b2, J2SDK 1.4.1

We've run some more tests, and documented them. The results are totally
consistent and reproducible across all my developers' machines. We develop
targeting JRun, but we've tested against Tomcat and seen the same
IndexOutOfBoundsException. The cause is always due to the misidentification
of an ArrayList attribute as a PropertyDescriptor instead of an
IndexedPropertyDescriptor. In the table below are our testing outcomes.
Success means that the ArrayList attribute was correctly identified as a
IndexedPropertyDescriptor and the code ran without exceptions. Fail
consistently means that the ArrayList was misidentified causing an exception
to be thrown.
We see the problem in JRun and Tomcat, so we can rule out the App Servers.
We see the problem in 1.1b2+1.4.1 and Nightly+1.4.1. I've written a test
case independent of struts that examines my ActionForm
(Introspector.getBeanInfo, beanInfo.getPropertyDescriptors) and regardless
of which JDK I'm using, the results come out correctly each time.
That leads me to believe that something funny is happening to my ActionForm
somewhere in the Struts code. Has anyone else seen this?? I have three
developers who came across this error independently so I have to imagine
that some of you out there bumped into it too when you moved up to JDK
1.4.1.
App Svr; Struts Rel; JDK; Outcome;
-------; ----------; -----; -------;
JRun 4.1; 1.1b2; 1.3.1; Success;
JRun 4.1; 1.1b2; 1.4.1; Fail;
Tomcat4.0.9; 1.1b2; 1.3.1; Success;
Tomcat4.0.9; 1.1b2; 1.4.1; Fail;
JRun 4.1; Nightly; 1.3.1; Success;
JRun 4.1; Nightly; 1.4.1; Fail;
NONE; NONE; 1.3.1; Success;
NONE; NONE; 1.4.1; Success;
thanks in advance for you suggestions.

This is the Struts configuration file for the example application,

NOTE: You would only flesh out the details in the "form-bean"

the corresponding Java classes for you. Otherwise, you would
need only the "form-bean" element itself, with the corresponding
