ObjectModified error

[Anonymous]

When I use ObjectModified event to do something and following code causes error:
private void callback_ObjectModified(object sender, ObjectEventArgs e)
{
try
{
using (Transaction trans = HostApplicationServices.WorkingDatabase.TransactionManager.StartTransaction())< br> {
/*do something*/
trans.commit();
}
}
catch (Exception ex)
{
/*do something*/
}
}

the code crash at StartTransaction(), then I cannot fix it.
Thanks for help

I don't think you can use transactions in that context.

What is it you're trying to do?

I want to update BlockReference.

Store the id of the notifying object, and then
open it later, after the operation is complete
