Hi ,
I got error like this:
[2010-Dec-27 10:51:41.239569] 4037 [/ SHrtNzkDFewEiUCe] [error] "Error during
event handling: Cannot map tables after schema was initialized."
[2010-Dec-27 10:51:41.239765] 4037 [/ SHrtNzkDFewEiUCe] [fatal] "Cannot map
tables after schema was initialized."
I don't understand why how can I map a table to use in two functions ?
