I have created custom objects called Issue and CaseIssue. The Case has a many to many relationship with the Issue object. So the CaseIssue object is a junction object, and the CaseIssue object is a child of the Case.

I would like to create a custom button on the CaseIssue related list, where when I click on it, the modal that presents itself looks like a standard record creation page, but it reality, the user is creating both the CaseIssue and the Issue record.

What is the high level approach to building this? What pages, components, apex code, etc. is needed? Anyone willing to draft some pseudo or sample code? How long do you think this should take an experienced developer? I want to get a high level idea before giving this work to the developer.

I have a custom field on a custom object with a default picklist value. When I create a record via the UI, the default value is respected. But when apex creates the record, the default value is not respected, and the field remains blank. I am not using record types. It is not a controlling or dependent picklist.
