Events onChange and onEnter cannot be used at the same time.

SWDP_WB_TOOL573
- &1: onChange and onEnter must not be used at the same time ?The SAP error message SWDP_WB_TOOL573 indicates that there is a conflict in the usage of the
onChange
andonEnter
event handlers in your Web Dynpro application. This error typically arises when both event handlers are assigned to the same UI element, which is not allowed.Cause:
The error occurs because:
onChange
event is triggered when the value of an input field changes and the user leaves the field (focus is lost).onEnter
event is triggered when the user presses the Enter key while the input field is focused.Using both event handlers simultaneously on the same UI element can lead to ambiguity in how the application should respond to user input, hence the error message.
To resolve this error, you need to ensure that you are using either onChange
or onEnter
, but not both, for the same UI element. Here are the steps to fix the issue:
Identify the UI Element: Locate the UI element (e.g., input field) in your Web Dynpro application where both event handlers are defined.
Decide on the Event to Use: Determine which event handler is more appropriate for your use case:
onChange
.onEnter
.Remove the Unwanted Event: Edit the properties of the UI element in the Web Dynpro component and remove the event handler that you do not need.
Test the Application: After making the changes, test the application to ensure that it behaves as expected without throwing the error.
By following these steps, you should be able to resolve the SWDP_WB_TOOL573 error and ensure your Web Dynpro application functions correctly.
