    First, sample application lacks other controls than text fields.
    ------------------------------------

    So, when I use <html:checkbox property="test" /> control I get java.lang.NullPointerException in my Action class.
    Why?

    java.lang.NullPointerException
    at net.aejase.plugin.wizard.WizardUtils.getActionFormFields(WizardUtils.java:120)
    ...

    My struts-config.xml file is properly configured.
    I've tried to do nothing in my Action class, but the java.lang.NullPointerException still occures.

    My ActinForm contains properly defined methods:
    public void setTest(boolean proba) { this.test=proba; }
    public boolean isTest() { return test; }

    Field test is initially set as false.
    My ActinForm also contains adequate reset() method.

      If I look into the code, the exception is thrown when the API try to access the FormConfig of the action you've specified in your wizard:helper tag.

      Check if the parameters are good.
