ERR_BUTTON_EXPECTED error
The request is invalid. The action to perform is missing. ERR_BUTTON_EXPECTED.
This error message can be displayed in several cases:
  • A link is specified in the HTML page with the [%URL()%] syntax without button name in the parameters:
    Solution:
    in the parameters of a link, specify the name of button in the WEBDEV page corresponding to the action to perform.
  • A click was performed on a button found in the HTML page only. This button does not exist in the page.
    Solution:
    The buttons found in the HTML page must have an equivalent in the corresponding WEBDEV page.
  • A form validation is performed without using a button (using some JavaScript code or validation performed via the ENTER key).
    Solution:
    A button must be used to perform the validation of a form.
    Tip:
    To allow the user to validate a form with the Enter key, simply define a "Validation" button in the WEBDEV page and associate it with the Enter key ("Details" tab of the control description window).
