Sending a value from a celltable to a view

[Sandney Farias]

I'm using a celltable and trying to send the register key when the user click in one item. My first doubt is about the correct way to send and get this value. 

This the code to send the value

selectionModel

            .addSelectionChangeHandler(new SelectionChangeEvent.Handler() {

                public void onSelectionChange(SelectionChangeEvent event) {

                    Banco selected = selectionModel.getSelectedObject();

                    

                    if (selected != null) {

                        History.newItem("RootPlace:banco/"+selected.getKey());

                    }

                }

            });

I'm getting the value in this way Window.Location.getHash().substring(Window.Location.getHash().indexOf("/")+1) as a string, that can't be cast to a key value

As you can see my doubt should be very stupid but I googled a lot and found nothing that could help me to solve the question. 

I apologize if my question is very basic and appreciate any response or indication of page where I can find a way to solve my problem.

Thank's Sandney

try   String  token=History.getToken();  //RootPlace:banco/123

  String key = token.split("/")[1]

Sugar_xj,

I'm getting the value. My problem is that the application get a string value and isn't possible cast this to a key value.

Let me try to explain what I'm trying to do. I have a UI with a celltable where the user will click in one line and my application will send the key value to another UI. Like as send a value by GET method between two pages, I need the key value because the application will use it to make a query like this   

Datastore.query(banco).filter(banco.key.equal(key)).asSingle();

Thank's,

Sandney Farias

                        History.newItem("RootPlace:banco/"+selected.getKey());

                    }

                }

            });

What do you mean you getting the value but isn't possible to case this to key-value?

what String are you getting ? and what is the key-value you are expecting  to cast? for example  you get the String   "RootPlace:banco/123"

For example  you get the String   "RootPlace:banco/123" I got the string and extract "123", but when I'll use it in the line Datastore.query(banco).filter(banco.key.equal(key)).asSingle(); 

the key have to be a object of KEY type and isn't possible cast a String type to a Key type.

Thank`s again.

now I understood what you said  that you " isn't possible cast a String type to a Key type."

you get String from url anyway, maybe you should try to change the type of banco.key as String type  or create a String field for 

banco.key and setters getters....
