Retrive through uicomponent binding backing bean object
I have an HtmlInputTextArea. It has as value a property of an object of an
arrayList.
<h:inputTextarea cols="30" binding="#{translationsBean.inputCountry}"
immediate="false" value="#{translation.localTranslation}">
Is it possible *through binding* of the component...
public HtmlInputTextarea getInputCountry() {
return inputCountry;
}
public void setInputCountry(HtmlInputTextarea inputCountry) {
this.inputCountry = inputCountry;
}
to retrieve at runtime the corresponding backed object. Something like:
inputCountry.getBackingBeanObject
Thanks

Hi,
May I inquire what your use case is? There's a way to do it, but it's very,
very funky:
1. ValueExpression valueExpr = component.getValueExpression("value");
2. String expressionString = valueExpr.getExpressionString();
3. Parse the string the remove the last element of the EL
4. Recreate a ValueExpression object with the modified String
5. Evaluate the ValueExpression
As you see, it's complex and providing us with your real use case would
allow me to give you a better alternative.
Regards,
~ Simon
