Hi all,

I am trying to create a trigger on the User object that will create a corresponding Contact record and update that Corresponding record when the user record is updated. This has been quite a learning process for me, and I thought I was nearly there when I decided that I should also try to sync the User.Manager field with the Contact.ReportsToId field.

My solution for this was to create a field on the User object to store its corresponding Contact's id, which would allow me to pull the ContactID right from the User record that was chosen to be the Manager and then fed into into the ReportsToId field on the Contact. The challenge is that because this is a User trigger I have annotate the methods with @future. I was hoping that I could update the Users from the same method that Inserted the new Contacts. In other words, when a user is created my trigger would create a new Contact then after that Contact is created the same class would update the User.ContactID__c field with the newly created ContactId. This results in the following error 'System.AsyncException: Future method cannot be called from a future method.'

I then turned to the documentation to find it explicitly stated that this was not possible, and it also stated that it was not possible for an anottated method call a trigger that calls an anottated method. So I guess that rules out creating a second trigger on the Contact object that would update the User object after insert.  At this point, I feel like I'm in a conundrum and would appreciate any suggestions.

Thanks,
