First, I don't have anything to post as far as code, because nothing has worked even remotely so far. I've written several extensions that allow me to 'look down' to child data (for instance, all the Campaign Members associated with the current Contact), but I have a new request, and I'm not sure how to proceed.
We have an object called IssuingFirm__c. It has two child objects called Issue__c and Filing__c. I need to be able to return data from all three objects to a visualforce page that starts at the Issuer__c object.
I can use the Standard controller to get the data from Issue__c, and query the data on the IssuingFirm__c record using relationships, but I'm not sure how to go 'up' to the IssuingFirm__ and then back down to Filing__c.
Any guidance, or a link to documentation that will help is appreciated.
