SetValue does not change text in "Yes/No" Choice column

Posted on by JN-27032010-0

I am trying to change the value of a "Yes/No" choice column using JavaScript in a model driven app.

If the user selects "Yes" in the form field, I am checking if other fields have a value.

If some do not have values, I need to change the form field the user changed back to "No"

I am using setValue to do this:

formContext.getAttribute('asp_railcarisgone').setValue(false);

This is technically working, the value of the field is set to false but the text in the field stays "Yes"

I need the text to change to "No"

How do I do that?

In a model-driven app, when you update a Yes/No choice column using setValue(false), sometimes the UI does not refresh immediately. To ensure the text updates properly, follow these steps:

Solution:

After setting the value, fire the OnChange event and refresh the control:

formContext.getAttribute('asp_railcarisgone').setValue(false); formContext.getAttribute('asp_railcarisgone').fireOnChange(); // Trigger the change event formContext.getControl('asp_railcarisgone').refresh(); // Refresh the UI

Why this works:

setValue(false): Updates the value in the background.

fireOnChange(): Ensures any event handlers tied to the field (like business rules) execute.

refresh(): Forces the UI to reflect the change.

This should make the field visually update to "No" when you set it to false. 🚀

@AllanMouraDev

Thank you for the quick reply.

and thank you for turning me onto refresh :)

It looks like formContext.getAttribute('asp_railcarisgone').refresh() is not a function.

but formContext.data.refresh() is.

Unfortunately, that does not work.

I don't understand why though, from the documentation it says it "Asynchronously refreshes and optionally saves all the data of the form without reloading the page" but that is clearly not happening.

If I use a success callback function on the data refresh, it says it is successful, but my field still says ""Yes"

Here is what I am using:

formContext.getAttribute('asp_railcarisgone').setValue(false);
formContext.getAttribute('asp_railcarisgone').fireOnChange(); <-- I don't think this is needed though since all it does is call the onchange event which is the function we are currently in.
formContext.data.refresh();

Try using the number value of false like:

formContext.getAttribute('asp_railcarisgone').setValue(0);

Maybe this will work, but lets keep on trying to solve that!
