java - Test CheckBox on NestedTree fails -

i built tree application based on nestedtree example www.wicket-library.com/wicket-examples, i'm struggling @ testing component using wickettester.

with wickettester trigger ajax event on checkbox:

tester.executeajaxevent("path:to:checkbox", "onclick"); 

the ajaxcheckbox onupdate event fired well, it's model doesn't change.

a simple page ajaxcheckbox , propertymodel works fine, model changes expected:

add(new ajaxcheckbox("check", new propertymodel<>(this, "checked"))); 

is impossible test component wickettester?

you'll have set value checkbox, executing click won't send input in request:

formtester.setvalue("path:to:checkbox", true);
