I don't practice in CA but bankruptcy law is federal and so I can comment generally on how bankruptcy affects an association's ability to collect.
When someone files for bankruptcy, an automatic stay arises preventing creditors from taking action to collect debts owed by the owner. Chapter 7 bankruptcies, once discharged, eliminate the owner's personal liability for any amounts due through the date of the bankruptcy filing. Bankruptcy discharge does not affect an association's lien against the property.
As long as the bankruptcy case is open, the automatic stay remains in effect. In order to take action to foreclose the lien or collect post-petition debt, one of two things must happen. Either you must obtain "relief from stay" - permission from the bankruptcy court to take the requested action - or you must wait for the bankruptcy to be discharged and closed/terminated.
You should consult with an attorney experienced in both community association law and bankruptcy law who can advise your association on whether to move for relief from stay or whether to simply wait until the bankruptcy case is closed. Check out the California chapter of the Community Associations Institute - they should have a list of experienced community association lawyers for your reference.

Because you filed an assessment lien before the bankruptcy, the unpaid prepetition assessments are not automatically discharged. You have to ask the court to set aside the automatic stay to proceed with the foreclosure. If the member also has an unpaid mortgage, the lender has priority to do the same thing, so the prepetition assessments are probably uncollectable.
The automatic stay operates only on the collection of prepetition debts. Any debts that arise after the petition you may still try to collect. But, if the member does have a lender that is foreclosing on him, you cannot do much, anyway. Even if you recorded a lien for postpetition assessments, the bank's foreclosure would wipe it out.
