• How to manage a transitional calculated attribute in my vo than sometimes groovy expression of null values?

  Mr President

  My worm jdev is 12.2.1

  In my transient VO sometimes attribute I have null values in the expression groovy

  (Purqty*Unitpurprice)+ (Purqty*Unitpurprice)*Staxrate/100
  

  Some products have sales tax rates, and some have Staxrate NULL.

  And I get the following error because of this.

  

  My question is that how to avoid this error.

  Concerning

  You can do a null control in your expression.

  If (Staxrate! = null & Salestax! = null) {}

  Return ((Purqty*Unitpurprice) + (Purqty * Unitpurprice) * Staxrate/100)

  }

  else {}

  Returns 0

  }

  Thank you

  I finally made it through the PR and PFR controller (when a record is selected) methods.  It works, but I was looking for a hook in the what the VORow instances are created.  As thecreateInstanceFromResultSet method but at this time the transient attributes do not exist in the result set.


• The order/agreement be attributed during the animation

  I mean, that is, if an object is in the rear when I mouse over it, it's the front, and then when I mouse out it goes back to the rear? I'm trying to do something like this http://codecanyon.net/item/dynamic-accordion-banner-rotator/full_screen_preview/628296

  or somethng like this http://codecanyon.net/item/fancyfolio-jquery-portfolio-gallery/full_screen_preview/1595481

  Hey Jason, you can set the z-index of an object on board, to change the display order.

  In the example below, "your_object_name" is the purpose of down that you want to move forward/backward. Start with the object 'your_object_name' below the other object.

  In the event of "mouseover" of your object, add the following:

  SYM. $("your_object_name") .css ("z-index", "100");

  In the event "mouseout/mouseouthandler()" of your object, add the following:

  SYM. $("your_object_name") .css ("z-index", "0");

• How to display a value of transitional attribute to column db entity column?

  Mr President

  Help me at the time 12.2.1 jdev.

  How to display a value of transitional attribute to column db entity column?

  I have the requirement to indicate a value of transitional attribute column in the column db entity for some reason any.

  Any body can help as my show in the picture below

  The StAmt is a transitional column and a column db of the entity.

  

  Any body can help please. !

  Concerning

  This means that the amount to be the attribute will always has the same value of the transient attribute? If so, why do you want the amount attribute the transient attribute is sufficient?

  Anyway, if you want to get attribute data in attribute transitional amounts you can open class ViewRowImpl and appearing in the getter or amount, you can get the value in the transitional as attribute:

    public Number getAmount()
    {
      return getTransientAttribute();
      //return (Number) getAttributeInternal(AMOUNT);
    }
  

  in this case, the quantity data store database will not appear on the table it will still get the transitional attribute data and it's meaningless.

• Research on the transient view object attributes

  Hi all

  I have a view X object that has a one-to-many relationship with another object view Y. In there, I have a State attribute that maps to a column of table and X, I have a transitional status attribute that is not mapped to any column in the table. Implementation of line class I derive the status of the status of all the is because the logic of the State is too complicated for a SQL of x. I also search page and brought to provide the ability to search on x status but because the attribute is transient is not considered during the search. What options I have to allow the user to perform a search on an attribute that must be derived? Any suggestions are welcome.

  I use JDeveloper 11.1.1.7.

  Thank you

  Bill

  Option 1:

  If the calculation of x attribute status is too complicated for the implementation as a SQL in queries or SQL expression, you can implement the calculation in function stored in DB (for example as a PL/SQL function) and map the VO attribute to this request of the VO function. In this way, you will make the x status attribute derived from SQL instead of a transient and then you will be able to do filtering against it in the SQL query.

  Option 2:

  If the calculation is a sort of grouping or ranking/grouping and your Oracle DB, you can try to implement the calculation using some of the built-in analytical functions of Oracle, who are very powerful and useful for tasks.

  Option 3:

  If none of above works for you, you can opt for filtering in memory instead of filtering at the level of SQL in DB. You can do this by setting the mode of the corresponding ViewCriteria (i.e. your search pane is based) to 'In memory' instead of 'Database' or 'Both '. This way your VO will retrieve every x lines in memory and the ViewCriteria will filter them in memory after that. This approach is not good, however, if X contains a very large number of lines, because all these lines must be read into memory before filtering.

• How to disable and enable fields already existing lines dynamically in the update page?

  Hi all

  I have a requirement where in detail RN (updated), I don't want the user to update the already existing line.

  In the area of retail, I have two columns, 1)-> existing supply must be read-only.

  -> Enabled 2) must be editable.

  For a newly added line (after clicking on add a line), offer both enabled column must be editable.

  For this model, I did table detail with text entry fields and set read only property: ${oa.offervo1.isOfferdis}-> offerDis is a transient (boolean) added in OfferVO.

  I should be able to field offers to read only to existing data.

  How can I set isOfferdis as true (aside from CO or AMimpl)

  and

  How do I set iaOfferdis as fake when add line button (I add line set up features)

  Thank you and best regards,

  Gauthier

  Hi AJ,.

  A surprise, I was able to reach the requirement,

  

  The code in RowImpl remains even as you suggested.

  

  However the default value of the transitional isOfferDis attribute as false (in VO).

  

  Then it works.

  I don't know why our code in AmImpl could not achieve this goal.  If you have any solution please share will try...

  Thank you and best regards,

• Table tree select questions

  Hi all

  I use Jdeveloper 12.1.2.0.0.

  My requirement is to select the checkbox all rows in a table from the tree root level when the user clicks a checkbox control named selectAll (this box resides outside the TreeTable). If the user disables the selectAll checkbox all rootLevel in tree lines must be unchecked.

  The tree has two levels. I used a transitional mode attribute in the t and when the user clicks the selectall checkbox, ValueChange Listener fires and I'm looping through the lines of the iterator, setting the transient value to be true.

  It works fine all the time but not the first time. When I click on the for the first time selectAll checkbox, the ValueChange listener fires but the treeTable lines are not get verified. The second time, it works perfectly.

  I have a partial trigger to the TreeTable.

  If I use a button instead of a check, it works fine all the time.

  Could someone help me.

  Do not know what causes this. Have you tried in jdev 12.1.3?

  To work around the problem, you can but a button hidden on the page and the queue an event to actin the listener to change value of the check box for the button. So easy the key dies at work, and it should work.

• [FAD] A few questions on the article of Timo "JDev: always test your application with the ApplicationModule Pooling disabled.

  Hallo Timo,

  I read your article JDev: always Test Your App with the regrouping of ApplicationModule turns off | JDev & amp; amp; ADF Goodies and I have some doubts.

  • I understand that you have disabled to AM pooling only to show the problem and the applications in production should always work with 'M bundling active. Right?
  • The substitution of activateState and passivateState functions must be performed when the AM is used to store data that is specific to the user. Right?
  • To store the data of the user in the AM, it is necessary to use the mechanisms of session? Or I might just add to the private variables AM (username, name, departmentName,...) to store the information of the user?
  • I see you used the Session instead of HTTPSession class to manage the session. What are the differences between these classes? Session the recommended class to use is?
  • Where can I find which are the main stages of the life of the session and functions to manipulate? 1-2 examples of creation, destruction, making the session which expires after e.g. 10 minutes of user'sinactivity... would be happy if possible.

  Thanks a lot a lot.

  • I understand that you have disabled to AM pooling only to show the problem and the applications in production should always work with 'M bundling active. Right?

  Yes

  • The substitution of activateState and passivateState functions must be performed when the AM is used to store data that is specific to the user. Right?

  Given no, everything must be save in the activation/passivation. If you store something for use wide application and don't save during passivation, he went by activating the module application ID again.

  • To store the data of the user in the AM, it is necessary to use the mechanisms of session? Or I might just add to the private variables AM (username, name, departmentName,...) to store the information of the user?

  I like to keep the info in the plan to use session.

  • I see you used the Session instead of HTTPSession class to manage the session. What are the differences between these classes? Session the recommended class to use is?

  The session that you get from the module of the application is not a http session it's a server session. You cannot use any other class.

  • Where can I find which are the main stages of the life of the session and functions to manipulate? 1-2 examples of creation, destruction, making the session which expires after e.g. 10 minutes of user'sinactivity... would be happy if possible.

  The documentation is always a good starting point. The best description I know is from the book "Guide Oracle ADF developer real world ' by Jobinesh Purushothaman. If you google a bit you will find another description too. Don't know what you want to know about the creation and destruction of the sessions that you do yourself. To set the time-out setting for the http session, you can change the value of "session timeout" in the web xml file.

• Eyedropper tool works is not on the text more as it did in previous versions

  Since Illustrator CC2014 the eydropper tool has lost a single function: before CC2014 you can easily copy attributes of text (from text) by selecting the text you want to change (B text) and click on the other, already in text (text) format. And got text attributes copied the text (B) So far so good, still working on CC2014.

  But that no longer works is the function who remembered attributes during your stay in eydropper tool and allow you to copy the text attribute has on any other letter, Word, or selected paragraph. Is it me doing something wrong or if the function is gone?

  This always works for me.

  Use the Eyedropper to pick up the attributes of text, hold down the Alt (Option) key, drag on a character, Word, etc.

  You will not see a choice, but it applies the attributes.

• sessionScope in Bind variable access to a display object

  Hi all
  
  I use jdeveloper 11.1.2.3.0
  
  I read some articles and messages on access sessionScope in Bind variable to a display object.
  If I understand correctly there is a differnece of opinion about it.
  
  In our applications, we use a lot of views with bind vars that use environment variables.
  as for now, we save the environment in the context of the session variables,
  and access them with a groovy expression in the var of binding of the VO.
  We also try to use adf.userSession.userData. But UserData is reset during the activation or passivation and all values of the variables are lost.
  
  What is the correct way to do it?
  Where we should record such as username, role and etc environment variables?
  values that are not changed through the whole session.
  
  I would like to know what is the best way to do it.
  
  Thank you very much!

  You must store the min the userdata in the model layer (groovy approach). However, you need passivate variables yourself. The framework does not automatically. You need to override the methods of activatesState (Element) in a request to passivate module data that you store in the userData plan and the passivatesState (Document, element).

  //In application module implementation class
  /**
   * Overridden framework method to passivate user data
   * in XML format by appending to the parent node
   */
  @Override
  public void passivateState(Document doc, Element parent) {
     //This code snippet stores the data in USERDATA node
    Element nodeUserData = doc.createElement("USERDATA");
    nodeUserData.setAttribute("KEY", "USER_DATA");
    // this sample only store one value regionId!
    nodeUserData.setAttribute("VALUE",
         getRegionId().toString());
    parent.appendChild(nodeUserData);
    super.passivateState(doc, parent);
  }
  /**
   * Overridden framework method to activate user data from
   * XML snapshot, stored during passivation
   */
   @Override
  public void activateState(Element parent) {
     //This code snippet reads the data stored in USERDATA node
    if (parent != null) {
      NodeList nl = parent.getElementsByTagName("USERDATA");
      for (int i = 0; i < nl.getLength(); i++) {
  
        Element e = (Element)nl.item(i);
        String key = e.getAttribute("KEY");
        String value = e.getAttribute("VALUE");
        setRegionId(new Integer(value));
        break;
      }
    }
    super.activateState(parent);
  }
  // regionId is made activation safe in this e.g
  private Integer regionId = null;
  
  private Integer getRegionId() {
    return regionId;
  }
  
  private void setRegionId(Integer regionId) {
    this.regionId = regionId;
  }

• How can I prevent the PSE 12 making unwanted crops when files are opened from disk?

  These are for the most part, Sony ARW files converted .dng 5504 x 3672 is reduced to 5472 x 3080.  The second figure see unacceptable information loss.  During the edition of 4.4 Lightroom it seems fine.  Other editors work well, too.  I forgot a preference setting somehow?  Thanks for any help.

  Mr R Kelly

  Thank you!  Worked perfectly 8.5 installed according to your instructions.  Questions of culture continued well until what I understood what was going on. Elongation of Sony have emerged during treatment in ACR (which I couldn't do far.). DNG Converter applied also aspect ratio of Sony that resembled a loss of information. Allows you to change the proportions of the RX100ii 4:3 the two types of files to be treatment of the same.  What looked initially like an only problem was, in fact, two.

  I still don't understand why it was so difficult to update to ACR 8.5.  I couldn't have done it without your help, however. I consider this issue resolved.

  Thank you

• Select the check box for the table of the ADF

  Hi all
  
  I want to add the check box in front of each line. The user will select the row by clicking the box and going to treatment by clicking on a button.
  
  I just almost all possible discussions on OTN.
  
  What I've done so now
  1] added a transitional Boolean attribute in my VO. added as a selectBooleanCheckbox in .jspx page.
  [2] a button with backing bean that will do the processing. [He will pick up the attributes of all ranks and be written in a file]
  [* 3] it works fine if I use the default option of line by Ctel selection + A, or by pressing Ctrl + click or SHIFT + arrow key. Backing bean is not the issue.*
  [4] try to intercept the TableSelection Listner also.
  
  It comes
  
  When I select the check box, only the last selected line is processed and not all lines. How to make the selectable online by clicking on the checkbox.

• When will be purged from the client of the View object properties.

  Hello!
  
  When will customer properties (settings-> general-> Custom properties VO) to purge the View object?
  
  Description of the custom properties is these properties are name / value framework for accessing execution.
  
  My case is: dynamically set some channels in the VO properties and use it.
  It works fine most of the time. But sometimes, these properties are missing. know when to leave intact page for a little while (about 20 minutes before the session expires).
  
  So my question is: what will miss these properties?
  
  I suppose it could be linked to the Application system of the State as your are hanging in AMS. And I'm might passivate. But in [this | http://docs.oracle.com/cd/E14571_01/web.1111/b31974/bcstatemgmt.htm] document shows any view to the level of custom data objects will be saved during passivation. So it is not the point.
  
  Can someone help?
  Thank you! :-)

  Hello

  Custom properties are not intended to be used as a data store, but to provide the setting for the items (a feature that is intended for highly reusable VO report). Sounds the informaton you set properties is lost during passivation of the view object.
