Mapped Properties in Struts 2

[Harish Panwar <ha...@gmail.com>]

Hi All,

We are migrating our website from Struts 1 to Struts 2. Everything is
working fine except the mapped properties.

Lets say we have text-field in our jsp:

<s:textfield name="arp(0)" />

Getter-Setter for this field were like this in struts1:

public String getArp(String key) {
    int index=Integer.parseInt(key);
    return prlist[index].arp;}public void setArp(String key, Object value) {
    System.out.println("set ARP: index:"+index+", value"+value);
    int index=Integer.parseInt(key);
    prlist[index].arp=value.toString();}

But now this is not working in struts2. On form submit method setArp() is
not executing.

For detailed description, please go to:

If you want to see what are mapped properties:
http://struts.apache.org/release/1.2.x/faqs/indexedprops.html#mappedprops

I am stuck at this point. I tried to google it but could not get any
satisfactory answer. People are suggesting to use  <s:textfield
name="prist[0].arp" /> , but because of dependent code and other reasons I
can not use it.


My question is whether Struts 2 supports Mapped properties or not. If yes,
then how can I use it.

Thanks,
Harish Panwar

You can use OGNL expression like this

<s:textfield name="%{getArp(0)}" />

but this is bad, very bad... design
