you could use a4j:support to trigger request. but onobject change is not similar to onunselect.
Thank you Ilya
Pardon me, I did not understand when you say "to trigger request"
In the demo example, you use the onclick with a call to callSuggestion(true) - how would that help here?
Do I put a a4j:support event on the suggestionbox control or the inputText ?
Use onkeyup event?
