[TYPO3-project-seminars] Error when editing new events

[Gunnar Hönekop]

Hi,

here is an error-message i receive when i edit a new event:

caller	t3lib_DB::exec_SELECTquery
ERROR	Unknown column 'NEW45b8921247cc0' in 'where clause'
lastBuiltQuery	SELECT *
FROM tx_seminars_seminars
WHERE
uid=NEW45b8921247cc0
LIMIT 1
debug_backtrace	sc_alt_doc->processdata // 
ux_t3lib_tcemain->process_datamap // 
tx_seminars_tcemainprocdm->processdatamap_afterdatabaseoperations // 
t3lib_db->exec_selectquery // t3lib_db->debug

When i dump the DB in the ext-manager the first call of editing a new 
evet is ok. But the next new event will show the error again.

Typo3 4.0.4
Seminars T3X_seminars-0_4_8-2007-01-23.t3x

Any ideas where the error comes from?

Thanks

Gunnar
