Indexed properties in forms

2009-02-10 Thread Ignacio de Córdoba 

Hi there,
I am trying to migrate a form population module from struts1 to struts2 and
I am not sure if struts2 supports indexed/mapped value properties.

After reading OGNL docs I see that indexed properties are supported both
with ints and objects. I guess they refer just to red de properties, not
to set them in the action... so I am trying:

s:textfield label=%{name} name='fieldEntry[%{id}]' / Where id is an
integer.

My action has the method:
public void setFieldEntry(String fieldId, String value){}
(I've tried fieldID with int, Integer and String)
(Also I've tried String value and String[] value just in case it expects an
array of strings)

When I submit the form I get:

2009-02-11 02:14:49,195 WARN  [com.opensymphony.xwork2.ognl.OgnlValueStack]
Could not find property [struts.valueStack]

You just need a collection/map getter/setter in the action, you don't 
need an indexed setter.
