Hello,

I have in my ui builder a textarea and under that a button. Now i want the value of the textarea to end up in a client script when something is entered in the textarea and then the button is clicked. For this I have selected “Execute Client script” for the button under Events and selected my created client script here. But now I can't get it to read the value from the textarea field in my client script. Can anyone help me here? I have following in my client script:

function handler({api, event, helpers, imports}) {

api.setState('textInput',event.payload.textarea_1);
}
But the value of textarea will be not filled. 
 
Thank you for your help
