my code was from ZK 6.5.3, it was working fine, and now I upgraded to ZK 7.0.0, I have this issue

I have <checkbox id="testBox" /> at .zul file

and Checkbox testBox; at the java controllor class, and which is autowired.

and I found out that, after run once testBox.setChecked(false);
and then run testBox.setChecked(true);

the check at the zul page would not checked in UI, but it is "true" at testBox.isChecked();

but if I run testBox.setChecked(true); first and then testBox.setChecked(false);, I do not have this problem.

I checked the source at github Checkbox.java did not update like 8 months ago, that should be problem at somewhere else?

Regards,
