  Hi Manu

  To do this, you can close the session Jdeveloper, then delete the files VO.xml and VOImpl.class, download the files VO.xml planted once more and try to extend it again.

  It could be useful!

• Write to the file of measurement with a loop For using the value of the dynamic data attributes

  I looked and looked, but couldn't find a solution for this.

  I currently have 15 points of different data that I try to write in an Excel file.  I have all combined in a table and lie with the function "write into a file position.  However, the column names are always "Untitled", "Untitled 1" etc.  I then used the function 'Set the Dynamic Data attributes'; but for this I have to do 15 different functions "set data dynamic attributes.  It was suggested to use a loop with the function 'Set the Dynamic Data attributes' inside of her, but I can't find how do.

  I have several arrays consisting of 15 different values for 'Signal Index' 'Name of Signal' and 'Unit', but also a unique 'get Date/Time In Seconds' related to 'Timestamp '.  The problem is that the error I get when I try to connect the output with Scripture at the entrance to measure file:

  The source type is dynamic data table 1 d.  The type of sink is Dynamic Data.

  How can I fix it?  I have attached a picture of my installation; Sorry if this is gross (I'm new on this!).  Thank you!

  It will get rid of the error, but it is not quite correct. What you need to do after that is to click on the output or the tunnel entry and select 'replace with the shift register. In addition, the array of values that you have wired to the Signal Index is wrong. Arrays are 0 based. Just wire the iteration Terminal here. And, finally, take the size of the table and this connection to the N terminal are stupid. Don't wire nothing to this.

• call a stored procedure for each row in the transitional attribute and display the data in the form of af: table. The other rows are based on the entities

  Hi Experts,

  JDeveloper 12.1.3.0.0

  I have a VO based on entity object. With a column of the VO is transient attribute (I created).

  I need to call a stored procedure for each row in the transitional attribute and display the data in the form of af: table. As well as other attributes.

  So can anyone suggest how can I achieve this?

  Thank you

  AR

  I think that you need a stored function (which returns the value) in this case, is not?

  Take a look at:

  https://docs.Oracle.com/CD/B31017_01/Web.1013/b25947/bcadvgen005.htm

  and search for:

• Where to add the transitional attribute at the level of the entities or view level? And where to use {return getTransientAttribute()} in the entity or view?

  Mr President

  JDev 12.2.1.

  Where to add the transitional attribute at the level of the entities or view level?

  And where to use {return getTransientAttribute()} in the entity or view?

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

  Concerning

  A difference I could think: place a transient attribute on EO level will make transaction dirty (DBTransaction.isDirty returns true) when the field is changed.

  From a design point of view, I tend to place the transient fields at the level VO, because most of the time they are for the presentation of the data in the user interface.

  Only when the transient fields are involved in DML operations (for example when you call a stored procedure EntityImpl.doDML) I place the transitional area on EO.

• 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.

• By default, the transitional attribute using sql

  
  Hello

  I use JDeveloper 11.1.2.4.0.

  I need to call a function to populate a transitional attribute.

  I thought I could do the following

  (function_name (PkId)), where PkId is an attribute that is selected in the query of the view object.

  But the result is that the value of the column in the select clause, the following

  Has_Visited_YN (PkId) AS VIEW_ATTR OF LEADSADMIN. LEADS_COMPANY LeadsCompanyEO

  Obviously, with this statement, including the clause, in the list of attributes in the select does not work.

  Any ideas?

  Yes, you can

  1. create transient attribute on the entity object.

  2 select attribute, and then click on the pencil icon to edit the attribute

  3 check the option derived from SQL.

  4. an area of Expression then you write sql like

  (select Has_Visited_YN (PkId) of double)

  and give the full name of the attribute as defined in the query tab view object.

  Name of Alias.Attribute instead of PKid.

  for eg - PayEmphdr.EMPCD

• Adding custom Transitions that include elements of color

  Hello, I'm currently adding a transition that I established in sequelae. The transition was recorded with an alpha channel, but has a certain element that is in color that I would leave it isolated. I tried different keys and mattes, but I have finally hit the wall and can't find other ideas.

  Can someone please offer suggestions?

  OK, it's easier in After Effects, but if you want to do first, here's a way to do it (Note: there are many ways to skin a cat and there may be a better way than that, but that's how I'd do).

  First of all, you must jump in After Effects and make two new versions of your "Swirl".

  Be the whirlpool as you have it now but the black area must also be transparent - you need the black box so that Matt will transport transparency it but also outside the blue and green zones:

  

  the checkerboard indicates the transparency.

  And you need to make a version where just the area that is black is became white and the rest of the image is black:

  

  We'll call him this mat cutter.

  On the timeline of the body, place the outbound scene on V1, the incoming scene on V2 and overlap the duration of your animation:

  

  I use color bars of the outbound scene with red color for the new.

  The V3, place the clip with the mat cutter. Then pass the effects Panel > Video Effects > Keying > overlay cache track and apply the track matte for the video on V2.

  When you open the controls for the Matt effect of track that you just applied, the value of the V3 matte. This should now cut the incoming scene.

  Then place the whirlpool with the clip color in synchronization with animation on V3 to V4. She "will cover" the area around the area of cut on the track below and you should now have your effect.

  You can see the result in the screenshot.

• Transitional attribute of VO and immediate property works only together

  I have an add a line and a button remove a line. Some validations if applied to the Add button, but these will apply the button Delete.
  For this I tried the immediate application property to true for the button = Delete. However, with the removal feature, there is a transitional attribute (Boolean type) that is not recognized (get null at the bean) what immediate property of the button Delete a real feature of deletion thus affecting.

  Make the component (in this case SelectOneBooleanCheckBox) by using the transient attribute as autosubmit = 'true '.

  This solves the problem.

• How to set the order in the table in the ADF for a transitional attribute in the default sort t

  Guys,

  I have a VO with 2 columns, the column is transitional attribute.  In my jsff page, I got an af:table that displays the transition attribute.

  When the page is loaded for the first time, by default, transitional attribute values should be sorted in ascending order. Currently, the displayed values are not sorted. I need to click the sort button to sort the values. I need to change this behavior to sort automatically when the page is displayed for the first time.

  Question: How can I set the command to the table in the ADF for a transitional attribute of default sort?

  Note: I have to pragmatically, I can't use order by clause in my VO for the transitional attribute.

  Help, please.

  Thank you

  Rambaud

  Hi Rambaud,

  You can do the sorting "in memory".

  You can implement it like this:

  Get the VO and make sure that all required lines are extracted from the DB

  ....

  Sort the rows by transient attribute

  myVO.setSortBy ("TransientAttribute");

  read the current query mode

  int oldQueryMode = myVO.getQueryMode ();

  to sort in memory

  myVO.setQueryMode (ViewObject.QUERY_MODE_SCAN_VIEW_ROWS);

  myVO.executeQuery ();

  redefine the query mode on original value (only needed if you want to be able to get new lines of the DB)

  deadlineVO.setQueryMode (oldQueryMode);

  I hope this helps.

  Kind regards

• Fill a transitional attribute using java

  I am very new to Oracle ADF.
  
  I created a view object, and it has a transition attribute. (Select value literal and not supplied). Now, I want to fill the column with another column in the same viewobject (there are some commercial calculations) of a Java class. No idea what class or how can I do?
  
  It is class rowImpl I write my logic? If Yes can you give an example?
  
  Here is an example of what I am seeking to create. We Department table in the Hr schema and employees loved with the foreign key relationship.
  
  DepartmentName Noofemployees percentage

  Admin 8 42.10526316
  Engineer 9 47.36842105
  Great Totatal 19 100
  
  Here's my transient percentage attribute. If the value is 2/19 * 100 OR 8 / 19 * 100, etc.

• Transitional attribute in object view

  Hello:
  There is a number to a relationship between table_i and table_s. accessors and links are created. Inside the table_i, I created a transitional attribute and I would like to refer to a column in the s table called LastName.
  
  In the expression of the transitional column in table_i, I have the following expression of EL: table_s.getAttribute ("LastName") but when I run the module application in the browser of the application, I get the following error: (oracle.jbo.expr.JIEvalException) Houston-25077: table_s name not found in the given object: ViewRow [oracle.jbo.Key [1]].
  
  What I am doing wrong? How can I use the debugger to see what is the correct name for the view? It should be the name of the view... right?
  
  The EL expression for the transitional attribute should be in the form of: viewName.getAttribute ("attribute in view") how can I watch it in the debugger to display the correct viewname or are there other conditions must be met so that it works? Maybe you have table_s exposed on a high level in the appmodule?
  
  Any ideas?
  
  Thank you very much

  You must use access - View or to get the attribute of the other partners VO.

• Dynamically add attributes to xmlelement

  Hello
  
  I'm trying to dynamically add attributes to an xmlelement. All attributes are stored in a table.
  So what I create a column that contains the attributes in a single line, for example: "sal" = "1000" mgr = '9827.
  
  So now, I have a query like this:

  select XMLElement(evalname ename)
  from emp;

  Gives me:

  <scott></scott>
  <james></james>

  ...
  
  What I want to do is to add this attribute to the element, then I me

  <scott "sal"="1000" mgr="9827"></scott>

  ...
  
  What I've tried is:

  select XMLElement(evalname e1.ename, XMLAttributes(e2.my_attributes))
  from emp e1, (select ename, '"sal"="100" "mgr"="9876"' my_attributes from emp) e2
  where e1.ename = e2.ename

  But which translates:

  <SCOTT MY_ATTRIBUTES="&quot;sal&quot;=&quot;100&quot; &quot;mgr&quot;=&quot;9876&quot;"></SCOTT>

  Someone at - it an idea how to get arround this? I tried with updateXML but I always quotes that have escaped.
  Or is there a better way to dynamically add attributes that are stored in a table?
  
  Thank you very much.

• How to load a transitional attribute via PopUp

  Hi all
  
  I'm working on a requirement where I have to load a transitional column through the pop-up window. I created a view object and added an additional column that it defined with default values as a string. I did drag the view on the page as one object
  
  ADF table and surrounded with collection of panels and inserted a button that opens a pop-up window. In the context menu and dragged a dialogue. I dragged the object of the view as a form in dialogue. Define the partial panelcollection
  
  triggers popup and dialogue. The additional column that I added to the view object is not in the database table. I am able to run the page and enter the data in the context menu and when I click on ok in the pop-up data are
  
  is only filled in the fields he defined in the database table. The additional column that I created is not be filled with data. It is simply show as people with reduced mobility. What could be the problem. What else
  
  I should have done? Please help me in this.
  
  Thanks in advance

  User, please always tell us your jdev version.

  You must add the attribute to the EO as an attribute (with always updated) transient and then build the VO on this EO. We should work OK as the VO don't now that the attribute is not saved in the DB.
