Expression Language in Java; simple, but impossible?

[beligum]

Hi all,

I've been searching for a solution to this simple issue for over an hour now:
How do I dynamically interpret an EL-string in Java-code?

I found this:

FacesContext context=FacesContext.getCurrentInstance();
ValueExpression vex=context.getApplication().getExpressionFactory().createValueExpression(context.getELContext(),"#{paramValues.mapSelectedItems}", String[].class);
String[] itemx=(String[])vex.getValue(context.getELContext());

But it doesn't work in Seam (1.2.1).

Any suggestions?

Answer to my own question for future reference:

String str = (String)Expressions.instance().createValueBinding("#{yourElString}").getValue();

[fhh]

Or simply:

@In(value="#{yourElString}")
private String str;

This will only work if the el expression does not change dynamically.

Regards

Felix
