I'm having a weird issue with qlikview 12 version.
I build an object extension which works fine on the other Qlikview versions but, when i upgraded my QV version (to 12) it started to work weird and not as expected, it seems that the issue is with getting the data from properties.
la forma en como lo resolvi fue abrir varios tableros de prueba y guardar hasta que me logro guardar el primer cambio con exito, apartir de ahi ya no se presento el problema
