How to build “edit” button in JSF and switch between h:outputText and h:inputText

Question

How can I create an \"edit\" button so that when the button is clicked it will change the h:outputText to h:inputText?

Answer 1

Make use of the rendered attribute:

...

With this in a view scoped bean:

private boolean editmode;

public void edit() {
    editmode = true;
}

public void save() {
    entityService.save(entity);
    editmode = false;
}

public boolean isEditmode() {
    return editmode;
}

// ...

Note that the bean being view scoped is important for the reason mentioned in point 5 of this answer: commandButton/commandLink/ajax action/listener method not invoked or input value not updated.

Alternatively, you can use the disabled attribute on input component in combination with a shot of CSS which basically makes it look like an output component (by removing the border).

...

with e.g.

input[disabled] {
    border: 0;
}

Also here, the bean must be view scoped. See also How to choose the right bean scope?
