Sometimes the feature setting value is duplicated

I have something very strange happening in my custom feature.

I have this in my module config for the setup:

<featureSetting
     resourceFile="rediResources"
resourceKey="Voce1"
defaultValue=""
controlType="TextBox"
        controlSrc=""
        helpKey=""
        sortOrder="100"
     regexValidationExpression=""
    />
<featureSetting
resourceFile="rediResources"
resourceKey="Voce2"
defaultValue=""
controlType="TextBox"
        controlSrc=""
        helpKey=""
        sortOrder="1000"
regexValidationExpression=""
/>
<featureSetting
resourceFile="rediResources"
resourceKey="Voce3"
defaultValue=""
controlType="TextBox"
        controlSrc=""
        helpKey=""
        sortOrder="1000"
regexValidationExpression=""
/>

Now, if i go to the module setting page, (http://localhost:60941/Admin/ModuleSettings.aspx?mid=8&pageid=7) , i get two "Voce1" items

But, if i go to the module definition setting page, (http://localhost:60941/Admin/ModuleDefinitionSettings.aspx?defid=37), i can only see one "Voce1" item.

If i rename it to "Voce1b", then on the module setting page it won't duplicate. But, renaming it again to Voce1, will make it duplicate it again.

What I'm doing wrong?

Re: Sometimes the feature setting value is duplicated

The thing to understand is if you rename a setting (resourceKey) it does not update the existing setting it is the same as creating a new setting. Once you rename it in the config file there is nothing there to tie it to the previously created setting. So if you rename a setting (or remove one) in your custom feature you should implement an upgrade script to delete the old one from mp_ModuleSettings and mp_ModuleDefinitionSettings making sure to use your featureGuid in the where clause so that no settings with the same name from other features get deleted.

Hope it helps,

Joe
