jsf - Managed property - Unable to set property -


i'm trying use managedproperty:

from here

@managedbean(name = "selectionbean") @sessionscoped public class tableselectionbean implements serializable {     private string selectionmode = "single";     private collection<object> selection;     private list<monitoringdata> monitoringdata;     private list<monitoringdata> selectionmonitoringdata;

to here:

@managedbean(name="actionbean") @sessionscoped public class monitoringactionbean implements serializable {     private threadpoolexecutor executor;     @managedproperty(value="{selectionbean.selectionmonitoringdata}")     private list<monitoringdata> selectedmonitoring;

and got following error message:

com.sun.faces.mgbean.managedbeancreationexception: unable set property selectedmonitoring managed bean actionbean ... caused by: java.lang.illegalargumentexception: cannot convert {selectionbean.selectionmonitoringdata} of type class java.lang.string interface java.util.list

any idea why not working?

it seems you're forgetting hashtag:

@managedproperty(value="{selectionbean.selectionmonitoringdata}")

should be:

@managedproperty(value="#{selectionbean.selectionmonitoringdata}")
