I believe that the issue here is that the bean:define needs to be able to
resolve the reference "regions["<%= elementNo%>"].region_ent" at compile
time - not at run time.
I belive it literally gets a copy of the bean property that you are
specifying and creates a new bean from it that it attaches to the page
contect. This means that you then reference the copy of the Region in the
page context - not the offset into the array of Regions in the initial
bean.
Because of this behavior I believe it needs to be able to resolve the
location of the object it's going to create the bean from at compile time.
Not sure to be honest -
Check the DefineTag source code to be sure. It's in the source tree at:
org\apache\struts\taglib\bean\DefineTag.java
FWIW -

Subject: [Q] bean:define dynamically
Hi guys,
I wish to define a bean:id as
<bean:define id="entitybean" name="RegionForm"
property="regions["<%= elementNo%>"].region_ent"
type="java.util.ArrayList" scope="session"/>
I tried giving <%= elementNo%>
<bean:write....>
but it didn't work.
Is there a way to do this?
FYI,
where RegionForm has attribute
java.util.ArrayList regions;
String elementNo; // get populated on selection
default="0"
regions is a list of class type Region.
Region class has attribute
java.util.ArrayList region_ent;
