Travis Lee 6 Translating Maps to Lists in Apex?
Hey there,
I'm trying to create a class that I can invoke with a process. The process exists on the Opportunity and needs to invoke a class that will unsync the current quote. I'm a new developer, but this is what I've researched so far. Based on this blog post (http://salesforcekings.blogspot.com/2014/09/how-to-automatically-sync-new-quote.html), I can't use a trigger. I found an example of a class that I think will accomplish what I need, but it's a future class (not required for my scenario, I don't think). Here is that example that I'm pilfering:
Since I need it to be invocable by a process, I believe I need to include the @InvocableMethod annotation. When I do, I get an error that says the Map<Id, Id> is an unsupported parameter type and I have to use List instead. So I started switching the Maps over to Lists and this is where I get stuck because the "get" parameter on line 11 below isn't compatible with List methods I guess? This is where my knowledge starts to drop off.
Any advice on the code above would be great, but I'd also like to understand a bit more about why I'm experiencing these errors with Maps vs. Lists. Thanks in advance!

So it was syntax error in your code.
