Anyone have any creative ideas for how I can solve this warning?
EL syntax error: Expression cannot start with binary operator
caused by the following code:
String.format("#{myController.deleteItemById(%d)}", getId())
My code looked like this before:
"#{myController.deleteItemById(" + getId() + ")}"
but this caused eclipse to generate the following warning:
EL syntax error: String is not closed
UPDATE:
@ManagedBean(name = "myController")
@ViewScoped
public class MyController implements Serializable {
private long id;
private HtmlPanelGroup panel;
public long getId() {return this.id; }
private void getPanel() {
/// bunch of code for programatically creating a form
HtmlCommandButton deleteButton = new HtmlCommandButton();
deleteButton.setId(id);
deleteButton.setValue(value);
deleteButton.setActionExpression(/* EL expression used here */);
}
}
