Availability of OnChange-Event

[Former Member]

Hello,

i expected an OnChange-Event to be available with input fields in the new WebDynpro4ABAP in Netweaver 7.1 EHP1. Unfortunately i am unable to find it.

Is this event available on NW 7.1 EHP1?

Is it planned to be downported to NW 7.0 and/or NW 7.01?

Thanks

Florian

There is no onChange event in Web Dynpro ABAP InputField in NetWeaver 7.0, 7.01, 7.02, 7.1, 7.11, or 7.20.

7.02/7.20 will add the AJAX callback for value suggestion via the new SuggestValues property. However there is no freely programmed onChange event planned for these release.

Thanks for your quick reply Thomas. Sorry to hear that. Wasn't there an onChange-Event announced on the TechEd? I also read many presentations featuring this new event. What was the reason for dropping it finally?

It has appeared in some slides, yes, as possible future event. Web Dynpro Java in NetWeaver CE 7.11 does have an onChange event for the InputField - which is why it appears in some slide decks. However it might also not be what you expect. The inputField has to lose focus as well has have a changed value in it before the onChange event fires. Therefore it isn't an interactive callback as the values are changed.

Firing the complete Web Dynpro Phase Model for every character typed during input would be quite costly. That is why the AJAX callback used for the SuggestValues doesn't fire the whole Phase Model - it uses a special, direct access to the just the SearchHelp processing for this one field.
