在UIInput组件中使用带有参数的方法时，如何调用setter方法？

Question

Before I have used methods with arguments to obtain the values of a component on my JSF page, for example

<h:dataTable value="#{myBean.getMyList(argument)}">

However now I need the same principle, but using it on a value attribute of an inputText element, so it would be more or less like this:

<h:inputText value="#{myBean.getMyValue(argment)}">

The problem is that the second method will not invoke the setter method, when executing the element from af:ajax element.

What would be another way of passing values to the setter and getter methods on the backingBean?.

Thanks a lot.

It's indeed not possible to set a value on an EL expression which does not represent a getter. You'd need to turn myValue into a Map<String, Object> and use the following notation.

<h:inputText value="#{myBean.myValue[argument]}">

This will then call the put() method on the Map . Note that you don't need a setter for myValue here.
