How to put EL into setRendered()?

I need to set visibility of an UIInput component programmatical and with a binding:

<h:inputText rendered="#{mybean.visisble}" />

uiInput.setRendered(boolean); doesn't do the job.

Instead I tried:

It doesn't work.

Instead I tried:
FacesContext context = FacesContext.getCurrentInstance(); Application app = context.getApplication(); ValueExpression valueEx = app.getExpressionFactory().createValueExpression(context.getELContext(), "#{mybean.visisble}", Boolean.class); uiInput.setValueExpression("rendered", valueEx);

It doesn't work.

I suggest that instead of doing:
rendered="#{mybean.visisble}"
do:
binding = "{BB.inputText}"

Then in the backing bean on some condition activate the inputText
example:
BB:
HtmlInputText inputText = new HtmlInputText();

constructor(){
inputText.setRendered(false);
}
public void someMethod(){
inputText.setRendered(false);
}

If you look at the JSF documentation you will see that when the object property is changed JSF will re-render the object. The way you have done it the re-render will not occur. Hope this helps.

Thank you for your help!

I was trying to build something like this from java code:

The ValueExpression as described above works well. My fault was to use
.setValue("#{bean.visible}");, which neither works nor results in an error message, as setValue expects a plain Object. But the String isn't parsed
as an expression value. Instead one must call .setValueExpression("value", vExp) too.

To give a more complete source example for the use of ValueExpression:
