Strange component instanciationin in PAGE scope

[swenvogel]

Hi,

i encountered the problem that component are created several times
when used in PAGE scope.

For test cases i created three classes ActionOne, ActionTwo and QueryOne.
QueryOne is injected into ActionTwo and ActionOne, ActionTwo is
injected into ActionOne.

Her are the simple test classes:

ActionOne:

@AutoCreate
@Name("actionOne")
@Scope(ScopeType.PAGE)
public class ActionOne  {

 @In
 private ActionTwo actionTwo;
     
 @In
 private QueryOne queryOne;
     
 @Create
 public void create() {
  System.out.println("-> ActionOne.create(): " + this.toString());
  System.out.println("   actionTwo = " + actionTwo.toString());
  System.out.println("   queryOne = " + queryOne.toString());
  System.out.flush();
 }

 public void doAction() {
  System.out.println("-> ActionOne.doAction(): " + this.toString());
  System.out.println("   actionTwo = " + actionTwo.toString());
  System.out.println("   queryOne = " + queryOne.toString());
  System.out.flush();
          
  queryOne.doQuery();
  actionTwo.doAction();
 }
}

ActionTwo:

@AutoCreate
@Name("actionTwo")
@Scope(ScopeType.PAGE)
public class ActionTwo {

 @In
 private QueryOne queryOne;

 @Create
 public void create() {
  System.out.println("-> ActionTwo.create(): " + this.toString());
  System.out.println("   queryOne = " + queryOne.toString());
  System.out.flush();
 }

 public void doAction() {
  System.out.println("-> ActionTwo.doAction(): " + this.toString());
  System.out.println("   queryOne = " + queryOne.toString());
  System.out.flush();
          
  queryOne.doQuery();
 }
}

QueryOne:

@AutoCreate
@Name("queryOne")
@Scope(ScopeType.PAGE)
public class QueryOne {

 @Create
 public void create() {
  System.out.println("-> QueryOne.create(): " + this.toString());
  System.out.flush();
 }

 public void doQuery() {
  System.out.println("-> QueryOne.doQuery(): " + this.toString());
  System.out.flush();
 }
}

Here is the console output where you can see that the components are created
several times, for example 7x QueryOne!

10:01:10,930 INFO  [STDOUT] -> QueryOne.doQuery(): test.QueryOne@9e7bc

When i change the scope of the components to CONVERSATION everything works
fine and every component is created only once:

10:27:55,743 INFO  [STDOUT] -> QueryOne.create(): de.moneyman.test.QueryOne@682598
10:27:55,743 INFO  [STDOUT] -> ActionTwo.create(): de.moneyman.test.ActionTwo@17c4973
10:27:55,744 INFO  [STDOUT]    queryOne = de.moneyman.test.QueryOne@682598
10:27:55,745 INFO  [STDOUT] -> ActionOne.create(): de.moneyman.test.ActionOne@d2dc0a
10:27:55,745 INFO  [STDOUT]    actionTwo = de.moneyman.test.ActionTwo@17c4973
10:27:55,745 INFO  [STDOUT]    queryOne = de.moneyman.test.QueryOne@682598
10:27:55,747 INFO  [STDOUT] -> ActionOne.doAction(): de.moneyman.test.ActionOne@d2dc0a
10:27:55,748 INFO  [STDOUT]    actionTwo = de.moneyman.test.ActionTwo@17c4973
10:27:55,748 INFO  [STDOUT]    queryOne = de.moneyman.test.QueryOne@682598
10:27:55,748 INFO  [STDOUT] -> QueryOne.doQuery(): de.moneyman.test.QueryOne@682598
10:27:55,749 INFO  [STDOUT] -> ActionTwo.doAction(): de.moneyman.test.ActionTwo@17c4973
10:27:55,749 INFO  [STDOUT]    queryOne = de.moneyman.test.QueryOne@682598
10:27:55,749 INFO  [STDOUT] -> QueryOne.doQuery(): de.moneyman.test.QueryOne@682598

But the page scope should be wider than the temporary conversation scope!
So why are the componentes created several times when used in page scope?
