Betreff: [mantisbt-help] Enumerations with Empty Value
Gesendet: Mo, 27. Jun 2011
Von: Jon Hardcastle

Guys,

We wanted to have a selection of values but have blank as a valid option so we set up an enumeration with the following:

|1|2|3|4|5|6|7|8|9|10|111|12|13|14|15|6|17|18|19|20

But unless you select 1~20 it keeps reporting that the value must be provided... any clues?

MantisBT 1.2.4

Thanks
