Hallo all,

i have a combobox with databinding. When the combobox gets new data about databinding, no onChange-event is fired. When the combobox have an determined value i will set another combobox to visible or not.

Anyone have an idea?

Hi,
I am also very new to ZK so my answer may be wrong, but I will try anyway.

I think without some kind of server push you won't just get new data into the combobox. Even if there is a databinding on it, it will not check for new data nonstop. So how do you get the new data into the combobox? If you are using load-after: 'xxx.onClick' or something like that, then you could try to do the check within that onClick method that is triggering the combobox databinding.

How did you define the value of your combobox? are you using the value of the selected item?

It would be helpful if you could post some code so that it is easier to see what you are trying to do.

Best regards
Tobias
