Custom VF Button, Custom Controller?

Again, I think the answer is "No", but I want to make sure. I want to add a custom VF button to a standard layout. (I want this button to be conditional, and would have used an S-Control if they weren't going away.) I want to add this button to many different standard layouts. I want to use a custom controller with this button and, as far as I can tell by reading the doc, I cannot use a standard controller and a custom controller at the same time. Also from the doc, I am required to use a standard controller.

 

Please note that I want to use the SAME VF button on multiple layouts, including standard and custom objects.

 

Is this possible? And if this is possible, how can I do it?

 

TIA,

 

John

This worked:

 

public class genericStdControllerExtension {

    private final SObject obj;
    
    public genericStdControllerExtension (ApexPages.StandardController cntrl) {
        this.obj = cntrl.getRecord();
    }

    public String getId() {
        return 'Id: ' + obj.get('Id');
    }
    
    public String getType() {
        return 'Type: ' + obj.getSObjectType();
    }
}
 
Now that I have the object ID and type, I can create programmatic relationships without having an underlying object relationship.

Read the doc about extensions.  You can use extensions with a standard controller, which allows you to use any kind of custom logic that you want.

OK, I tried that. Since I want to be able to extend ANY standard controller, I tried this:
 
public class genericStdControllerExtension {

    private final SObject obj;
    
    public genericStdControllerExtension (ApexPages.StandardController cntrl) {
        this.obj = cntrl.getRecord();
    }

    public String getStdId() {
        return 'Id: ' + obj.id;
    }
}
 
All I really want is the ID of the object. Once I have that, I can implement my custom logic and all's well. 
 
Problem is, I get this error message:
 
Error: Compile Error: Field expression not allowed for generic SObject at line 13 column 27 
 
Is the error in my code, or am I trying to do something impossible?
 
TIA

XXX,
 
What do your VisualForce pages look like in this case? 
 
Is there anyway to have just one VisualForce page that is used on a Lead, Opportunity, Case, etc, but still leverage the data in their respective standard controllers? 
 
Thanks,
Jon
