Javascript Error for Dropdown: oAccessibilityHelper is Undefined

[daniel_humberg]

I have developer a WebDynpro (ABAP) component that has a DropdownByKey.

The component is embedded in two different compoents that are part of different WD aplications.

In application A, everything works fine, but in application B, I am getting a JavaScript Error when clicking on the dropdown.

The error message is "oAccessibilityHelper is undefined".

What can I do? Why are the two applications behaving differently? I could find no difference so far.

Because of Web Dynpro's closed rendering system, nothing you do should really be able to cause a JavaScript error. Anything of a mistake should be caught and reported by the Web Dynpro layer. So if you have a reproducable JavaScript error you should really search for support notes/open a support ticket.

You are right, I have opened a ticket.

If available, I will post the notes needed to correct this into this post.
