Remove default value "val" for SingleLine.Text (empty value) in Test Harness

Hello!

 

I am trying to use a SingleLine.Text for coloring of a label in my react code control.

Now I have 2 suggested themes, but with the property ClearColor in the manifest I want to allow the user to change the preset colors.

Unfortunately the Testharness always fills in the value "val" so I cannot simulate the situation of having no input for the color (thus the component should use the suggested theme color).

 

Is there a way to remove the value of val?

 

I've ready tried setting the default to an empty string:

 

        <property name="ClearColor"
                  display-name-key="Clear color"
                  description-key="Clear labelbutton"
                  of-type="SingleLine.Text"
                  usage="input"
                  required="false"
                  default-value=""/>
 
Even setting
        context.parameters.ClearColor.raw = null;
 in the init is overwritten apparently.
 
 Obviously I can implement the logic of when the value is empty it should use the theme value, but that doesn't work if "val" is the default testharness initialization value.
 
Thanks for any help!

    Hello,

    Here is what you can do:

    1. Run harness using npm start command
    2. Hit F12 to open the DevTools
    3. Navigate to "Application" tab
    4. In the left navigation expand "Local Storage" and look for "http://localhost:8181"
    5. In the list of the stored properties on the right look for "<Your Namespace>.<Your Control Name>_properties".
    6. Make a tweak to the "Value" field to set the "Default" for your property (it doesn't accept null or blank string and resets it to "val" - I used " " in this case)
    7. Refresh the harness page.

    Good luck.
