Hi,
Here is the description and solution of a problem I ran into yesterday. I have a big table with many fields, so I grouped them with the "group" option of fields.ini. However, a date field did not work: the content was never saved, and if left blank there was no error message, even though I had a validators:required = true option.
The fields.ini options for this field was:
[FechaAlta]
group = "Identificación"
order = 5
widget:label = "Fecha de entrada"
widget:type = "calendar"
validators:required = true
Interestingly, other date field worked perfectly:
[FechaApertura]
group = "Estado"
order = 16
widget:label = "Fecha de apertura"
widget:type = "calendar"
validators:required = true
I realized that FechaAlta worked if I removed the "group" option in fields.ini. Finally, I removed the "ó" HTML entity from the group name (Identificaci—n), and it worked. I played adding other entities, and definitively it was the cause for the field not to work.
I hope this helps someone.
Cheers.
