问题 I'm looking into using apex scheduler to run a batch job. We can run it whenever we want, say 3 am when traffic is low, but I'm trying to anticipate some 'Oh-Crap' Scenarios. Can you guys help answer these questions for me? Setup: When the user modifies a territory 100k's of records can get updated. Questions: What are some scenarios that can realistically cause my jobs to not terminate? I thought of a scenario of- when a user is editing a contact which happens to be in one of the batches is

问题 I want to write a unit test that checks that callout hasn't been made from the trigger. I know how to test if the callout is made correctly - by implementing HttpCalloutMock: global class MyHttpCalloutMock implements HttpCalloutMock { global HTTPResponse respond(HTTPRequest req) { //test HTTPRequest here } } But if no HTTP request is made, then the respond() method won't be called. So this approach doesn't test if the request was made at all. I need something like this: HTTPRequest

问题 I'm just wondering if anyone else has seen this and if so, can you confirm that this is correct? The documentation claims, as you might expect, that 10,000 is the record limit for the system call: Database.emptyRecycleBin(records); not 200. Yet it's throwing an error at 200. The only thing I can think of is that this call occurs from within a batch Apex process. 回答1: This is the only reference that I could find to there being a limit of 200 on emptyrecyclebin(), I dare say that you are

问题 When I setup a visualforce page with a <apex:selectRadio> that is inside a repeat, I cant seem to get the selected value back into the controller. If I move it out of the repeat, it works fine. Any ideas?

问题 In a Javalike language where parsers and other advanced methods do not exist I want to parse and evaluate source files. It's the language Apex from the proprietary cloud platform Salesforce.com. I know its based on Antrl/Java but there is no way to parse it from inside the platform as I want to parse Apex code with Apex code and the only means is Regexp.
