jsf primefaces focus bootsfaces ajax-update

Bootsfaces inputText loses focus caused by using ajax and updating value in bean

I found a problem while using the bootsfaces inputText with ajax. I'm using JSF 2.2, Bootsfaces 0.8.1 and Primefaces 5.3.

I'm trying to enter a date value into the inputText field. As soon as I enter the last value for the date the inputText should trigger the change event. At this point I would like to use ajax for calling a bean method. The problem is, that my field loses focus as soon as I try to enter the last value and the method's never been invoked.

So I tried a bit with Primefaces and it almost works like I wanted. At this point I got different questions:

Why does my inputText field lose the focus while entering the last value? (Bootsfaces)
Why is the bean method never called after I lose the focus? (Bootsfaces)
Is it possible to invoke the bean method after the bean value has been set by the field? (Primefaces)

I added the code below, so maybe you can reproduce this behaviour.

    private String dateB;

    public void searchA() {

    public void searchB() {
        System.out.println("Search B");
    }

    public String getDateA() {
        return dateA;
    }

    public void setDateA(String dateA) {
        this.dateA = dateA;
        System.out.println(dateA);
    }

    public String getDateB() {
        return dateB;
    }

    public void setDateB(String dateB) {
        this.dateB = dateB;
        System.out.println(dateB);
    }

}

Please help me finding a solution or explain me what I'm doing wrong here.

Thanks mweber

Solution

You've found a subtle difference between BootsFaces and PrimeFaces. I recommend you always define the values of process and update for the sake of clarity. In your case,

    <b:inputText id="dateA" type="date" value="#{test.dateA}" immediate="true" class="form-control">
        <f:ajax event="change" listener="#{test.searchA()}" render="@none"/>
    </b:inputText>

makes the BootsFaces input field behave exactly like its PrimeFaces counterpart.

The default values of update and process are different. Since BootsFaces 0.8.5, the default values are:

process="@form" for <b:commandButton /> and <b:commandLink />
process="@this" for every other BootsFaces component
update="@form" for every BootsFaces component

According to Understanding PrimeFaces process/update and JSF f:ajax execute/render attributes, the PrimeFaces default values are:

I've tested it with BootsFaces 0.8.5.
