Item with unit can be changed only once in PaperUI

[mvalla]

I have an item in PaperUI connected with a channel of type Number:Temperature (with unit in Celsius).
I can edit the item from PaperUI > Control and change the number (temperature), but once I click the check mark to confirm the change and the item is changed (which is reflected in the binding logs), then the item cannot be changed anymore: the UI does not allow me to change the value.
Only by refreshing the page in the browser (F5) I can then change the value again.
See a small video of the current wrong behavior below:

(shown in the video: after the first change the item cannot be changed anymore until page refresh).

Tested with Chrome v68 and Firefox.
No error is reported on the Chrome developer console.

The problem is present in both openHAB 2.3 and 2.4.

The item is attached to the the following channel:

    <channel-type id="setpointTemperature">
        <item-type>Number:Temperature</item-type>
        <label>Setpoint Temperature</label>
        <description>The setpoint temperature</description>
        <category>Temperature</category>
        <tags>
            <tag>TargetTemperature</tag>
        </tags>
        <state pattern="%.1f %unit%" step="0.5" />
    </channel-type>

I can confirm this, I have experienced the same.
@htreu Is there any easy fix for this?

[htreu]

since I'm about to refactor the control view in Paper UI I put this on the list of issues to fix along the way. stay tuned.

[mvalla]

same issue appears even if no state is used in the channel-type definition

[htreu]

This should be fixed with #6131.

[mvalla]

it is not fixed for me. I just updated to origin/master and can report same wrong behavior in PaperUI

[htreu]

I will check again, thanks for the feedback.

it's ok now (the updated code was not being used in my Eclipse env)
