Trigger won't Fire

Question

I have a trigger to create a new Opportunity when a field on my Custom Object is changed, but it doesn't seem to be creating the new Opp. There are no errors, the new Opp is simply not created. I realize that it should only fire after update and not on insert.... What am I missing?

trigger MDwinning on MD_Meeting__c (after update) {
List <Opportunity> oppToInsert = new List <Opportunity> ();
for (MD_Meeting__c m : Trigger.new) {
    if (m.SD_Action__c=='Sales Accepted Lead') {    
    Opportunity o = new Opportunity ();   
    o.OwnerId = m.Sales_Director__c;
    o.Name = m.Name;
    o.Market_Developer__c = m.Market_Developer__c;
    o.AccountId = m.Account__c;
    o.Type = 'Sales - New Business';
    o.CloseDate = System.Today()+150;
    o.MeetingLookup__c = m.Id;
    oppToInsert.add(o);
    }//end if
}//end for o
try {
    insert oppToInsert; 
} catch (system.Dmlexception e) {
    system.debug (e);
} 
}

Remove the try-catch to see the fireworks (it's only in development environment, right? It's not like you'll cripple the ability to update meetings for all users). Or enable debug logging.

I suspect you're not setting Stage (StageName) and that's what is blocking the successful insert.

Once you have nailed & fixed it you might decide to either put try-catch back or use Database.insert(oppToInsert, false); - it'll try to save what it can.

P.S. Have you had a look at Summer'13 Chatter Action buttons?
