Handling Multiple check boxes

[Sreek Gupta]

Hi,
I have a Collection of value objects(say Employee(Id, name, dateOfBirth,valid etc..). One Action sets the collection in session and forwards to a JSP that displays a list of Employees using <logic:iterate> over this collection.
On each row of Employee information, one checkbox is provided to select whether employee is valid or not. Now if I select multiple checkboxes and submit the form(in JSP), I need the ActionForm to have a Collection that has Employee value objects. For this i declared String[] getters and setters for all the fields. Unfortunately i couldnt get unchecked values in my action form.
How can i get all the entries (whether it is checked or unchecked).
Please help me with code samples if possible.

Regds,
Sreek

I think there is a solution involving the struts multibox control.

Your action form needs to declare 2 arrays - one to hold the entire collection of choices, and one to store the 'checked' choices.

Summat along the lines of

<logic:iterate id="item" name="someForm" property="someFormProperty" scope="session">
  <TR>
    <TD><CENTER>
      <html:multibox property="theEmptyArrayToPopulate" >
        <bean:write name="item" property="theItemProperty"/>  
      </html:multibox>
    </TD>
    <TD>
      <bean:write name="item" property="beanProprty1FromFullArray"/>
    </TD>
    <TD>
      <bean:write name="item" property="beanProprty2FromFullArray"/>
    </TD>
    <TD>
      <bean:write name="item" property="beanProprty3FromFullArray"/>
    </TD>
  </TR>
</logic:iterate>

I *think* that's how it's done. I'll leave you to find out about re-setting the array!!

As!
