[rules-users] Guvnor enumerations

[Stephen Masters]

There seem to be a few bugs with Guvnor enumerations.

The editor can't deal with more than 15 enumerations in a single file. Any more get hidden off-screen so that they can't be edited. The issue is in both Chrome and Firefox.

See these two enumerations?

'MyFact.currencies': (new com.myapp.guvnor.enums.CurrencyEnum()).isoCodes()
'MyFact.currencies' : (new com.myapp.guvnor.enums.CurrencyEnum()).isoCodes()

The second isn't parsed correctly by the editor. Unfortunately, it turns out that if there's a space before the ":" (as per examples in the user manual), then when loaded into the editor in Guvnor, it doesn't recognise the "field". That text box ends up empty.

btw … Removing the space before colons in my enumeration definitions may have improved things so that I do at last see the correct field names in the "Field" column. However, the original issue still remains re. missing property accessors.

I don't suppose that anybody has managed to get data enumerations working in Guvnor 5.5.0.Final and could provide an example that works?

Cheers,

Steve
