Assigning values of a select list to a List object in the controller

Hello,

 

In my VisualForce page i have a select list whose values i want to pass to my Controller when the command button is pressed.

The select list  is defined as follows :

 

 <apex:selectList id="member_list" value="{!selectedMembers}" size="10" >
                 <apex:selectOptions value="{!memberNames}"/>
 </apex:selectList>

 The command button is defined as follows :

 

<apex:commandButton value="Save" action="{!move}" rerender="hiddenBlock">
              <apex:param name="selected" 
                value="{!selectedMembers}" 
                assignTo="{!selectedOptions}"/>

</apex:commandButton>
<apex:pageBlock id="hiddenBlock" rendered="false"></apex:pageBlock>

If im not mistaken, {!selectedMembers } is the set of all values in my select list.

Now, in my controller, how to define {!selectedOptions} as List <String> object ?

 

Please help

Thank You.

Define a list of the type of the members which i guess is String

public List<String> selected = new List<String>();

Thanks for the reply imuino.In my controller, i now have :

 

 

public List<String> selectedOptions = new List<String>();

 

But im getting the following error  .

 

Invalid conversion from runtime type LIST:String to LIST:System.SelectOption

 

FYI, the select list gets populated from the AccountContactRole table, but

public List<AccountContactRole> selectedOptions = new List<AccountContactRole>();

does not work either.

 

Where am i going wrong ?

 

Please help.

Thanks

Use List<SelectOption> instead of List<string>

 

I mean your apex class should contain the following method

 

public List<SelectOption> getmemberNames()
{
List<SelectOption> options = new List<SelectOption>();
options.add(new SelectOption ('A', '1'));
options.add(new SelectOption ('B', '2'));
return options;
}

 

and then define the get set methods for selectedMembers as follows

 

public void setselectedMembers(List<SelectOption> sops)

{
selectedmembers = sops;
}
public List<SelectOption> getselectedMembers()
{
return selectedMembers;
}
