Umbraco.slider initial value is always 0

[Deltids]

Reproduction

Bug summary

The initial value of the slider is 0 even though the UI shows a positive number and initial value setting is set to a positive number .

Orientation: Horizontal
Initial value: 15
Minimum value: 1
Maximum value: 30
Precision: 0
Tooltip: show

When I debug the application the property is initally set to 0.
If I go into the backoffice and change the slider to e.g. 14 and save and publish, it works, but up until that point its value is 0.

There is nothing in our application that interfer with this property in any way, so it looks to me as a bug in umbraco somewhere.

Specifics

This is umbraco 7.12.3

Steps to reproduce

• Create a Document Type with a slider property.
• Get the document content in a custom controller
  var myDocType = content.Children.OfType<MyDocType>.FirstOrDefault()
• Check the slider value on first page load MyDocType or saving it to a variable:
  sliderCnt = Convert.ToInt32(myDocType?.sliderCntProperty);

Expected result

Expected result is that the initial value of the slider value is initial value defined in settings.

Actual result

The value is 0

Hmm, unfortunately I can't reproduce in 7.12.3. Any javascript errors maybe?
If you have any more details then feel free to re-open the issue!

Ah, I just noticed the code you added above. Please note that the slider value will not be in the published content until you publish the document. So if you add a slider property the contact page of your site you need to go into the contact page and publish that page with the default value, otherwise the default value will just be the default value of int, which is 0.

So every time the site gets re-deployed, I have to manually go to the page and "Save and publish"? The page is in published state in the backoffice, and the slider shows 15 (though, slightly off)

I'm not sure what re-deploying has to do with it but I encourage you to try to get some help on the forums as the functionality works as expected.

Ok, I'll try.

It will still be my understanding that it is not working as expected, as the page with the slider is published, but the value is not available in published content. I would understand if the page status was unpublished.

Thanks for the answers.

That's the part I can't reproduce though, if I publish the value then it's available in published content as expected.

This is still a problem in 8.14 (the site im working on.)

If the initial value is untouched by the editor it returns 0.
I use the slider for defining padding. The bottom row has a initial value of 3 set - it renders 0.
The top row has an initial value of 3 set, which has been moved to another value and back to 3 and saved. it returns 3.
