Re: SOLUTION FounD : How to restore Models original Properties - Problem in Models column Exclude

Dear Alexis Roda Sir

Thank You very Much.

definitely Race Condition may arise if we do not put code inn critical section. But your suggested approach did not work and i found another alternative which is working fine. If we put this code with necessary care than will it be ok?

No, it isn't. It's not thread safe.

Changes in shared state in multi-threaded code may lead to race conditions[1].

Depending on your usage it may be very unlikely, but under the right circumstances root may end up having some missing fields in the form or dgp may see fields that it is not intended to see.

Either protect the critical section[2] with some kind of lock or, as I suggested in my previous answer, create non-shared (request local) state.
