Jsf. How To Post Backbean Object From Jsf Form To Javascript

Solution 1:

Even I can't give all answers, for me the filling of your hiddenInput should be managed as following:

@ManagedBean(name="imageAnnotations")
publicclassImageAnnotations  {

    privateString jsonString;

    publicvoidanyMethodFillingOrInitializingTheJSONString() {
        this.jsonString = resultOfYourWork();
    }

    publicStringgetJsonString(){
        returnthis.jsonString();
    }

    publicvoidsetJsonString(String item) {
        this.jsonString = item;
    }
}

When you reload this hidden input field, just be sure to trigger a javascript parsing the String and updating your client-side Model. This can be done via the on* - events you can connect with Primefaces buttons.

Guys, can anybody help with the other parts?
