• The purpose of programmatic view called several times ExecuteQueryForCollection

  [JDev/ADF v11.1.1.5.0]

  I am trying to create a VO that is not supported by DB, but instead takes its data from an external source (subsequently, a web service, but that's irrelevant to this question). I followed on each sample, I found and have created the VO and all overridden methods. I use this VO to create a LOV list for a VO another attribute, and the values in the LOV will vary based on a value in another attribute in the main volume (this is called LOVs cascading in various places).

  Here's an example, using the HR schema (a little artificial, I admit it):

  -Two your - DepartmentVO and ManagerVO - are defined

  -The DepartmentVO is supported by the DB and a normal EO and VO.

  -L' Manager in the DepartmentVO attribute is set to a supported by the ManagerVO LOV

  -The ManagerVO is programmatic and returns a list of employees who are in the same Department as the DepartmentID in the line of master DepartmentVO. To do this, use a Bind Variable (DeptId) that is set up to take the value of the DepartmentID attribute in the current line of DepartmentVO. This value of binding is used to filter the list of employees referred to only in the same Department.

  -J' replaced the executeQueryForCollection method in ManagerVOImpl. Here, I retrieve the value of the variable DeptId bind parameters passed in object/object2 to the method, and then use to retrieve employees in this Department of my main source.

  So far so good. Presents all works. (He lifts the employees in the same Department and displays them in the popup LOV.) If you change the Department then click to display the attribute Manager LOV, it shows you the list of employees in the new Department.)

  The problem I see is that the executeQueryForCollection method is called several times (2 or 3), causing the recovery of employees in the Department occur several times. For example, the test by running the AM executeQueryForCollection is called when I click the button to display the popup LOV (which makes sense). However, it is said AGAIN when I click the OK button in the popup LOV after selecting one of the values. (This should NOT!) And, if I create a JSF page and drop the data control to create a form and test it in this way, the executeQueryForCollection is called THREE times!

  I have the logic in the class ManagerVOImpl, which checks whether the list of employees has been recovered already, and if so, it's just returns the existing list. However, multiple calls are actually coming from different instances of the VO class, so that they only "see" the list has already been retrieved (because she was retrieved from another instance of the class, not this one).

  So my question is: How can I ADF do not call the executeQueryForCollection several times during the use of the VO as a LOV so that my (very expensive) call in the master repository to retrieve the list of employees is not executed more than necessary?  Is my only option to implement share caching mechanism myself that stores the list of employees of a Department somewhere in memory? I thought that ADF BC will make caching for me at the level VO?

  Thanks for any help that anyone can provide. I have literally been taken with that for two weeks, when I thought it would be a 'fast' to implement! :-)

  I'd be happy to upload/attach the source of my 'ManagerVOImpl' class, if that would be helpful.

  Have you tried to put a conditional statement in your back-end call happens only on your principal of the VO and not on the other 2 forums and see if that affects your functionality?

  that is, if (myIdName == "myVOInstance") {}

  do things;

  }

  I did it with VO this call that some heavy DB stored procedures in the executeQueryForCollection.

• Type of the object called several times Oracle constructor

  I have an object of type with a custom constructor. In SQL, when I reference attributes the constructor is called several times in Oracle 11.2.0.4.

  1. Why the constructor is called more than once?
  2. How can I stop it?

  My current job is about to reference attributes and use the / * + materialize * / tip.

  Problem

      -- Constructor is called 6 times! 
      -- Once for each column and once for each predicate in the where clause.
      SELECT x.f.bar1 AS bar1, x.f.bar2 AS bar2, x.f.bar3 AS bar3, f

      -- Work Around

      FROM y
      WHERE y.bar1 = y.bar1 AND y.bar2 = y.bar2
  

  Another solution is described in this thread... Access to the fields of an object custom type... which makes use of a type of collection combined with SCOREBOARD operator, like this...

  create or replace type FooTable as table of Foo;
  
  SELECT x.bar1 AS bar1, x.bar2 AS bar2, x.bar3 AS bar3, value(x) f
      FROM table(FooTable(
        foo(p_Bar1 => 1, p_Bar2 => 2, p_Bar3 => 3)
      )) x
      WHERE x.bar1 = x.bar1 AND x.bar2 = x.bar2
  ;
  
  BAR1 BAR2 BAR2 F
  1    2    3    (1, 2, 3)
  
  Foo Constructor Called

• at the start, computer turn on and off several times before finally starting

  Product: Hp Pavilion M9177C-B

  OS: Vista Edition Home Premium

  Approximately 2 weeks, when you start the computer by pressing the Start button, blue starting light turns on, then turns off maybe 6 + times before it turns finally for good and then I can hear the hard drives being accuated.  I fear that one of those moments that she not turn for good. So, I took the computer on at all times and just close the devices.

  Hello slodave,

  As you hear hard drives or anything on the spot for a while, it seems that the problem may be due to your diet.

  You can look at the power Panel there should be a light on the subject. See if it shows that it begins well before the computer actually turns on (so it comes at the time 6 + it is turn on/off).

  If the food will then replace just to continue normal operation.

  help me get the apple logo take off. I reset it, tried and failed to reset. I can't put it in dfu mode. I'm stuck and need help pease. I did everything that was mentioned in other posts similar to this issue.

  That may mean the iPod has a hardware problem, such as a faulty hard drive or the logic board.

  When you do a Reset (press and hold the Menu and Center buttons), going blank at the start before the Apple logo returns the screen to the iPod?  Or do you mean that the Apple logo is 'stuck' and it doesn't go away when you try of the reset?

• WhatWhere is the plug-incontainer? happened to the plugin container? He disappeared with the latest version and now firefox crashes several times a day.

  I do not see the plugin container in the task manager of Windows since the last update of Firefox and now FF freezes several times per day (since the previous update, before yesterday). It takes several minutes after that I see this until it thaws, and it is faster the "end task" and restart Firefox to wait. This most often seems to happen when the computer has been idle for a certain time, rather than when I use it.

  Be sure to let the process of plugin-container in the firewall.

• Managed Bean method called several times in AF:ITERATOR

  Dear all,
  I can do not to understand this concept in the ADF. Being a beginner, I would like to know
  the reasoning behind this.
  
  I use af:foreach components and then I link it to my below managed bean.

  <af:panelTabbed id="pt1">
       <af:forEach var="item" items="#{testBean.departmentsData}">
         <af:showDetailItem text="#{item}" id="sdi1"/>
       </af:forEach>
  </af:panelTabbed>

  public class TestBean {
      public List getDepartmentsData() {
          System.out.println("I was clicked!!!!");
          List lstData = new ArrayList();
          lstData.add("IT");
          lstData.add("Finance");
          lstData.add("Accounting");
          return lstData;
      }
  }

  On the first charge, it prints 7 times "I clicked".
  
  When I clicked on one of the tab, I get 7 again which means my method was called 7 times.
  Any reason behind this. ? Thank you.
  
  I have used JDEV PS3 is told by the way.

  Rather than build the list in your getter, build a list somewhere (in the constructor, perhaps). Your getter can then return just this list.

• I renew the DHCP on my Airport Express Extender several times a day.

  I have a time Capsule airport connected to an ATT Uverse router mode bridge as my wifi router.  I have Airport Express 6 throughout the House using wifi Extender.  I have to renew the DHCP lease on a large number of Extenders several times a day to keep them in line.  I saw a few discussions online about this problem, but have not found a solution that works.  Anyone know the problem?

  I have a time Capsule airport connected to an ATT Uverse router mode bridge as my wifi router

  Does that mean that the Time Capsule is in Bridge Mode... or... does that mean that the ATT Uverse router is in Bridge Mode?

  Help if we understood what operating system you use the device that you use to administer airports.

• Function used in the view definition is called several times

  I'm writing a view that boils down to the following statement:
  
  SELECT val, val)
  SELECT SYS_GUID() val
  OF the double
  )
  
  Against my expectation, which calls SYS_GUID() twice, resulting in two different values for val.
  
  I have written here as view inline, but it must be a regular view in reality. Is it possible to build this view while SYS_GUID is called only once, even if the resulting value is then selected several times? Naively, I want to affect the outcome of SYS_GUID to a variable, and then select the value of this variable. However, this seems not possible in a view.
  
  New to Oracle PL/SQL. This works as expected in T - SQL SQL Server.
  
  Thanks for any help or insight you can provide.

  Hmmm, I have no 11 + available so I can't check a solution, but I would like to test:

  SELECT val, val FROM (
  SELECT SYS_GUID() val
  FROM dual
  WHERE ROWNUM = 1
  )
  

  or

  SELECT val, val FROM (
  SELECT /*+ NO_MERGE */ SYS_GUID() val
  FROM dual
  )
  

  Edit: the no_merge indicator seems to work in 10.2.0.4
