[jira] Created: (WW-1534) The value of checkbox getted in
server-side is "false" when no any checkbox been selected.
The value of checkbox getted in server-side is "false" when no any checkbox been selected.
--------------------------------------------------------------------------------------------
Key: WW-1534
URL: http://issues.apache.org/struts/browse/WW-1534
Project: Struts 2
Issue Type: Bug
Components: Value Stack
Affects Versions: 2.0.1
Environment: tomcat-5.5.20 / jdk1.5.0.08
Reporter: Ling Chang Ming
jsp section:
<s:iterator value="%{#request.rolePs.items}" id="role" status="status">
<tr >
<td height="25" width="5%">
<s:checkbox name="roleId" fieldValue="%{id}" theme="simple"/>
</td>
</tr>
........
</s:iterator>
action section:
....
private String[] roleId;
public String[] getRoleId() {
return roleId;
}
public void setRoleId(String[] roleId) {
this.roleId = roleId;
}
.....
the retrieved value of "roleId" is {"false"} when user doesn't select any checkbox elements. In my opinion, this case should returns null directly.

Don Brown commented on WW-1534:
-------------------------------
Setting the property to null makes sense in this situation, but the more common one is where the property is a boolean. Any idea how we could construct a value that OGNL would treat as either null if the value is a string or false if a boolean?
