Question

in my web app I can’t get the key values of query parameters with a single validator.

My webpage:

    <f:metadata>
        <f:viewParam name="version" value="#{myBean.version}" 
            validator="#{myBean.inputValidator}" />
        <f:viewParam name="mobilemodel" value="#{myBean.mobileModel}" 
            validator="#{myBean.inputValidator}" />
        <f:event listener="#{myBean.preRenderViewEventHandler}"
            type="preRenderView" />
    </f:metadata>

My function to validate components:

public void inputValidator(FacesContext context, UIComponent component, Object value) throws ValidatorException {
        LOG.debug("Component: " + component);
        LOG.debug("Value: " + value);
    }

I can’t find the key value (ex. version) in the UIComponent

A solution that works fine is to have one Validator function for each query parameter. There is a way to understand the name of the parameter?

Next question: it’s possible to skip all Validators and set value to myBean? I tried, but the values was not setted in myBean.mobileModel

You can get all component attributes by UIComponent#getAttributes().

So, just this should do:

String name = (String) component.getAttributes().get("name");
// ...
