Re: manage sub-collection with grid component
sorry for being not so clear in my previous explanation,here the complete
code concerning my problem:
I need to show a list of products, and because each product can contain one
or more contents, I want to add a list of actionlink in the last column
representing the content list related.
@Entity
public class Product implements java.io.Serializable{
private long idProd;
private ProdType prodType;
private String idServiceType;
private String status;
private Date reqDate;
private String dex;
private Collection contents = new ArrayList();
@Id
@GeneratedValue
public long getIdProd(){return idProd;}
public void setIdProd(long idProd){this.idProd=idProd;}
@ManyToOne
public ProdType getProdType(){return prodType;}
public void setProdType(ProdType prodType){this.prodType=prodType;}
public String getIdServiceType() {return idServiceType;}
public void setIdServiceType(String idServiceType) {this.idServiceType =
idServiceType;}
public String getStatus(){
}
public void setStatus(String status){this.status=status;}
@Temporal(TemporalType.DATE)
public Date getReqDate(){return reqDate;}
public void setReqDate(Date reqDate){this.reqDate=reqDate;}
public String getDex(){return dex;}
public void setDex(String dex){this.dex=dex;}
@OneToMany(cascade={CascadeType.ALL})
public Collection getContents(){return contents;}
public void setContents(Collection
contents){this.contents=contents;}
@Override
public int hashCode() {
...
}
@Override
public boolean equals(Object obj) {
...
}
}
@Entity
public class Content implements java.io.Serializable {
private long idCont;
private Operator operator;
private String host;
private String folder;
private String fileName;
@Id
@GeneratedValue
public long getIdCont(){return idCont;}
public void setIdCont(long idCont){this.idCont=idCont; }
other setter/getter methods
}
public class ProductMonitor{
@ApplicationState
private DuckBeanRemote dao;
@ApplicationState
private Coordinator coordinator;
@Persist
private Product product;
public Product getProduct() {return product;}
public void setProduct(Product product) {this.product = product;}
public DuckBeanRemote getDao() {return dao;}
public void setDao(DuckBeanRemote dao) {this.dao = dao;}
public Coordinator getCoordinator() {return coordinator;}
public void setCoordinator(Coordinator coordinator) {this.coordinator =
coordinator;}
public Collection getProducts(){return dao.getProducts();}
public Object onActionFromSend(long
idProd){dao.sendProduct(idProd);return
this;}
public Object onActionFromLogout(String
username){coordinator=null;return
Index.class;}
}
ProductMonitor.tml
send
I need to show here the list of contents of
the current product
(idprod)

Re: manage sub-collection with grid component
Have you taken a look at the "Adding Columns Example" here
http://tapestry.apache.org/tapestry5/tapestry-core/ref/org/apache/tapestry5/corelib/components/Grid.html
?
Does that solve your problem ?

Dear all,
I need your support in order to determine the better way to solve this
situation.
I have, say, 2 entities (ejb3)
@Entity
public class Child {
private String idChild;
private String firstName;
private String secondName;
...
}
@Entity
public class Father{
private String idFather;
private Collection children;
...
}
And I want to build a table in this way:
- for each row, print all Father properties
- in the last column, I want to insert a list of links to the each child
related to the specific Father in the row.
I'm working on a grid component, so:
but what can I insert in the "childrenInfo" column?
I think that one solution could be a new component that accepts the idFather
as parameter, and then returns the html code for the Children list. Is this
a good idea?
Any suggestions/thoughts?
