In case you want to just show the record in the tabular, or a find is runnin, then I did just logging.
In case the client GUI shows old data, and the client selects the record to book it, a window opens to tell the client:
Upps, sorry! The record is vanished.
Is that what you requested.
Because of personal problems, I can not answer the next two weeks any questions.
Sorry, CU in weeks.
