It turns out that I needed to have the AjaxObserveField in the <wo:form> otherwise it returns an empty response, even though it sets the string value on the component and then calls its action to render again.

Isn't debugging Ajax fun! Well, not so much.

Hi,
I have an AjaxUpdateArea that lists hosts on a network and have it set to refresh every second incase a host drops offline. I also have a textfield in a wo:form to use to search the list. I put an AjaxObserveField in there to watch the text field, but everytime it fires the update, the host list blinks on the refresh, yet the auto refresh every second does not cause this blinking.


Does anyone know if this is a bug and how to mitigate it?


It sounds like an artifact of the JavaScript implementation. I think the only fix is to dig into what is happening in the JavaScript and see why one update is different than the other.
