I have a Java Object with many other nested Objects and lists of Objects.
When the request arrives from the client, I see that the Object is populated
only to a few levels. Is there any configuration that sets this is Struts 2?
Here is my example.
class MyActionClass extends ActionSupport {
private Abc abc;
public Abc getAbc() {
return abc;
}
public void setAbc(Abc abc) {
this.abc = abc;
}
public String populate() {
MyService myService = new MyService();
abc = myService.getMyAbc();
return SUCCESS;
}
public String update() {
MyService myService = new MyService();
myService.updateAbc(abc);
return SUCCESS;
}
}
class Abc {
private List<Def> defList;
private Ghi ghi;
public void setDefList(List<Def> defList) {
this.defList = defList;
}
public List<Def> getDefList(){
return defList;
}
public void setGhi(Ghi ghi) {
this.ghi = ghi;
}
public Ghi getGhi() {
return ghi;
}
}
class Def {
private String name;
private long id;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public long getId() {
return id;
}
public void setId(long id) {
this.id = id;
}
}
class Ghi {
private List<Def> defList;
private String ghiName;
public void setDefList(List<Def> defList) {
this.defList = defList;
}
public List<Def> getDefList() {
return defList;
}
public void setGhiName(String ghiName) {
this.ghiName = ghiName;
}
public String getGhiName() {
return ghiName;
}
}
When I call the `populate` method and when send to the jsp, the iteration
happens good with all the elements. But, when I try to update, i.e. when
then form is submitted, the `update()` method is called, but the instance
variable abc does not get populated completely.
I have seen the url which is passed and everything seems to be fine. Let me
tell you what happens. The url will be something like (splitting with line
break for easy understanding here),
&abc.defList[0].name=alex
&abc.defList[0].id=1
&abc.defList[1].name=bobby
&abc.defList[1].id=2
&abc.ghi.ghiName=GHINAME
&abc.ghi.defList[0].name=Jack
&abc.ghi.defList[0].id=1
&abc.ghi.defList[1].name=Jill
&abc.ghi.defList[1].id=2
In this case, the `defList` inside `abc` and `ghi.ghiName` in `abc` are
populated with no issues. But the `defList` of `abc.ghi` is not populated.
Is this a common behavior of Struts 2? Is ther any means by which this can
be overridden?
