According to the documentation: anonymous wrote : | The converter works with any entity which has an @Id annotation - either simple or composite. | But if I try to use it with an Entity that has a String as the @Id, I get a NumberFormatException: | java.lang.NumberFormatException.forInputString(NumberFormatException.java:48) | java.lang.Integer.parseInt(Integer.java:447) | java.lang.Integer.<init>(Integer.java:620) | org.jboss.seam.ui.EntityConverter.getAsObject(EntityConverter.java:80) | com.sun.faces.renderkit.html_basic.HtmlBasicInputRenderer.getConvertedValue(HtmlBasicInputRenderer.java:152) | So this would lead me to believe that it works only for numbers. Can this please be emphasized in the documentation? So what do I need to do? I guess I need to delcare my own converter? And then how do I get it wired in? Or could EntityConverter be enhanced to handle String @Id Entities? (Overload the get method in EntityConverterStore, and do some kind of class meta-data check in EntityConverter?)
