I have searched for a solution to replace the as deprecated marked ValutBinding stuff with a better solution.
For example if you have a method to retrieve a JSF Bean from the faces context:
public static Object accessBeanFromFacesContext(final String theBeanName, final FacesContext theFacesContext) {
final StringBuffer valueBinding = new StringBuffer();
valueBinding.append('#');
valueBinding.append('{');
valueBinding.append(theBeanName);
valueBinding.append('}');
final Object returnObject = theFacesContext.getApplication().
createValueBinding(valueBinding.toString()).getValue(theFacesContext);
if (returnObject == null) {
LOG
.error("Bean with name " + theBeanName + " was not found. Check the faces-config.xml file if the given bean name is ok."); //$NON-NLS-1$ //$NON-NLS-2$
}
return returnObject;
}
You can replace this now with following code:
public static Object accessBeanFromFacesContext(final String theBeanName, final FacesContext theFacesContext) {
final Object returnObject = theFacesContext.getELContext().getELResolver().getValue(theFacesContext.getELContext(), null, theBeanName);
if (returnObject == null) {
LOG
.error("Bean with name " + theBeanName + " was not found. Check the faces-config.xml file if the given bean name is ok."); //$NON-NLS-1$ //$NON-NLS-2$
}
return returnObject;
}
This retrieves a bean from the faces context. You can use the method for example to retrieve a TestBean form the faces context like
TestBean testBean = (TestBean)JSFUtils.accessBeanFromFacesContext("testBean", FacesContext.getCurrentInstance());
The TestBean object have to be added to the faces-config.xml as a managed bean. If the bean was not created at the point where you ask for it, the default constructor is called and the bean is created for you from the JSF framework.
