HowTo Make Data rendered as a combobox editiable [message #760711]

Hello,
In the EzBug example, I see where the Version Property data is rendered as a combo-box.

I cannot see any hints/annotations etc to allow the combo box to be editable.

How do I make a combo-box and in general, Properties that use enums editable.

Thanks

What is the scenario where an enum property needs free editing? By definition, the set of valid values held by an enum property is constrained at build time...

Thanks Konstantin,
I am uncertain if the enum mechanism is the correct or even the only option here. I was merely following the EzBug example.

Here is my scenario - with reference to a conventional combo box. Let say I have the combo that holds the title of a person as part of the person's full name. The combo is programmatically populated with the following items - Dr, Mr, Mrs. With the enum mechanism, there is no option to add another title such as "Professor", when registering a new person. How do I get around this for combo, and maybe on a broader level as it include Sapphire.

Thanks

The scenario you have described would be better served by a plain string property with @PossibleValues or a custom PossibleValuesService. See @PossibleValues.invalidValueSeverity and PossibleValuesService.getInvalidValueSeverity() if you wish to specify that values outside of the provided possible values are ok.

The presentation used will be a text box with content assist and a browse button. There is also an enhancement request to provide a secondary presentation of an editable combo box.
