Dear Developers,

I have a custom object called Leadevents__c who is connected to Leads. There I have built several custom onclick javascript buttons. For example one button called "Accept" that - besides other stuff - changes a field called "Stage__c" on that custom object.

Now I don't want my users to work any longer from that object itself but to work from the standard lead object. I have built an APEX Class and a Visualforce Page to display the relevant information:



What I am trying to achieve is that my commandButtons on the visualforce behave the same way my custom javascript buttons do on the leadevents__c object.

So when I am on a Lead, that has a Leadevents__c record displayed in that visualforce page and I hit "Accept" the Stage__c of that very Leadevents__c record should change.

While I was able to display the buttons themselve I have little experience in APEX. So there is no code behind these buttons! It's just for showing what I want.

Here is my APEX Class so far:

public with sharing class JTo_LeadeventOnLead {

    public Lead the_lead {get; private set;} 
    
    public string the_leadid {get; private set;}
    
    public List<Leadevents__c> the_le_list {get; private set;}
    

    public JTo_LeadeventOnLead(ApexPages.StandardController sc) {
        
        the_leadid = sc.getId(); 
        
        the_lead = [
                    SELECT id, Name, State, City, PostalCode, WirtschaftszweigWZ08__c,PLZ_erste_zwei_Ziffern__c 
                    FROM Lead
                    WHERE id = : the_leadid
                    LIMIT 1
                  ];
        

        
        if(the_lead != null){
            
           
            
                the_le_list = [     
                                        SELECT Id, Name,F_lligkeitsdatum__c,Phase__c,Datum_des_Leadevents__c,Unge_ffnet_JR__c,isClosed__c   
                                        FROM Leadevents__c 
                                        WHERE Lead__c = : the_leadid
                                        Order by F_lligkeitsdatum__c DESC
                                        LIMIT 5
                                  ];
       
    
    
}
}
}
