Hi Maicol,

so you have an inputbox and when the input exceeds a given number of characters you want to give a warning correct?

If the warning can happen right away in the view, I would suggest you write the input from the inputbox to a runtime variable and then have a KPI checking the length of that variable, giving appropriate warnings. You can then display the KPI right next to your input box:

1. Create Runtime variable: Name = value_box_input, the value has to be one space
2. Create KPI in your knowledge model: Name = Value Box Check, PQL = CASE WHEN len('${{input_box_value}}') > 10 THEN 'Input to large' ELSE 'Input Valid' END
3. Create your input box with the following yaml:

type: input-box

settings:

  type: string

  value: ""

  onChange:

    update:

      variables:

        - name: input_box_value

placeholderText: Type your input

Then you can place your KPI in a KPI-List component right next to your input box and see the screenshot for how it would look like:Let me know if that helps or if you have a question about it.

Best,

Tim
