Struts 2: Can not set Action's property which is an array of Strings
Hi guys,
My Action has property which is an array of Strings. I'm rendering html
table using this property. What is correct way to update this property from
jsp?
I tried the following but it doesn't work:
1. JSP
<s:iterator value="entityList" status="rowstatus">
<s:textfield name="selectedItems[%{#rowstatus.index}]"/>
2. Action
private String[] selectedItems;
public String[] getSelectedItems(){
return selectedItems;
}
public void setSelectedItems(String[] selectedItems){
this.selectedItems = selectedItems;
}
Exception is
[ERROR] 23:11:16,750 InstantiatingNullHandler | Could not create and/or set
value back on to object |
com.opensymphony.xwork2.util.InstantiatingNullHandler.nullPropertyValue(
InstantiatingNullHandler.java:110)| nullPropertyValue
java.lang.InstantiationException: [Ljava.lang.String;
at java.lang.Class.newInstance0(Unknown Source)
I will appreciate any help.
Thanks,
Andriy

Maybe you should consider buying an off-the-shelf web application or slowing
down a little to read the documentation. Popping in and asking for snippets
of code for this and a sample file to do that only shows that you are
looking for someone else to do your work. Have you searched *this* mailing
list using nabble.com? Perhaps this question has been answered already.

Andriy,
Try putting the array in an encapsulating object, i.e. an ArrayList.
