Proc je tam to update="false", to znamena, ze se hodnota sloupce nemeni ... pak
se to neupdatuje v db. Pouze se hodnota
ulozi pri vkladani noveho zaznamu ...
To neznamena, ze by se to nemelo nacitat data ...
Ja tam nic nevidim, co by me prastilo do oci ... rekl bych, ze UserType je v
poradku, nehazi to nejakou exception behem
startu?
