  Set the default value of the transient attribute to type of expression with a value like SkillView.avg ("Rating") where SkillView is the VO.

• Hide the line of adf table based on the transient attribute does not

  I have a JSF page where the user can insert new line in View object . this View object contains a transitional attribute which indicates whether or not the record is newly created.

  On the same page, I have a table adf which is bounded on the city view object . This table should show only newly created records. my approach is to use expression language of in the renditions property to hide all the other lines that are not newly created. I changed the render property for the columns of the table as: rendered="#{row.bindings.RowStatus.inputValue eq'new'}" , but the table does not show anything.

  Then, I tried to change the made not for the column property, but to the outputText inside the same way. It worked, but the problem is that the blank line is always on display.

  So, basically because I do not hide the entire line, instead I'm hiding the text in the lines and lines with spaces empty is still on display in the page aside.

  The Table of JSF page where the made property is applied on outputText inside the column:

  <af:table value="#{bindings.UplodedFilesView1.collectionModel}" var="row"
  rows="#{bindings.UplodedFilesView1.rangeSize}"
  binding="#{CreatSR_UserBean.fileTable}">

   <af:column sortProperty="#{bindings.UplodedFilesView1.hints.FileName.name}"
  headerText="File Name" id="c1">

   <af:outputText value="#{row.bindings.FileName.inputValue}" id="it1"
  rendered="#{row.bindings.RowStatus.inputValue eq'new'}"/>

   </af:column>

   </af:table>

  Thanks Timo,

  You are right. Its to late to hide lines after stamping in the row set. I solve the problem by filtering the view object, based on the transitional attribute in the section of liaison page. The steps as follows: (assuming that the object from view with the temporary attribute has been created, and the transient attribute contains the filtered values)

  1. Drag the view object on the page and also make the Table (in my case it might otherwise listen)
  2. On the page, go to the connection tab.
  3. Double-click the object desired in the links column.
  4. New window will appear titled with (change the binding tree)
  5. Check the option (enable filtering)
  6. Select the (filter attribute) and (filter value) for the selected filter attribute.
  7. Select (Display attribute) you want to appear in the page.
  8. Press OK

  Hello

  I think that your transient 'AdfCreatedName' attribute has updatable property was never in your ViewObject.

  Set it to always get the same look as your attribute of "approval status".

• How to add the transient attribute for LOV (object of the view read-only)

  I have a view called CustomerView and attribute DepartmentId is present in it.

  Also exists DepartmentView and CustomerView.DepartmentId has an LOV from this point of view.

  I need to add a transient attribute to CustomerView which express the DepartmentName attribute in the LOV.

  Because of the view are read-only there is no entity object don't match them.

  How can I write the groovy for the transitional object expression.

  The name of the view accessor Lov's DepartmentView1

  Looking for your help. Thank you.

  Hi gcoban

  I do not understand your question correctly,

  you are not able to write to the expression property in viewObject?

  or you want to know how to write groovy for that?

  for writing groovy you need viewAccessor and you who have, you can try as Alejandro Tovar Lanz suggested

  or you can write code in RowImpl to fill in the name of the Ministry of the accessor

  See -https://blogs.oracle.com/adf/entry/combo_lov_how_to_display

• Panel request: hide the transient attributes

  Hello

  I have an EmpVO that has a transitional attribute to say lets say for example age. I want to display on the page. This page is a panel request also with "Add", more fields dropdown. I don't want to display my age transitional attribute in the query Panel or adding drop-down fields.

  When I put the suspicion of display to hide in the indicators of control of the view at the age attribute, object, the value is NOT coming in the page. ID, I say 'Display' is 'also' showing in the query Panel.

• ADF ViewObject. Fill the transient attribute on ExecuteQuery

  Hi all

  I use Jdev 12.1.3.0

  I have a requirement to display the link within the cell of the column. and there is a chance that there may be multiple links in a single cell at a time.

  I get the table data (spacer) string, separated, if there are several links in a chain.

  Is it that I anticipate, create a transitional attribute and process data and fill attribute (spacer) transient data separated in the table list. And use this as an entry for the iterator to display in the cell of the column.

  But I'm not sure where to implement the that runs as soon as the execution of query.

  Please suggest.

  Thank you

  Vieira

  Hi user,

  You need not transitional attribute.

  Let's say that your attribute delimited by spaces of db table have the name 'space_separated_attr_from_DB '.

  First, create a managed bean property (say, iterTest), with type ArrayList, as follows:

  public ArrayList getIterTest(){
        // get  space separated attribute value:
        FacesContext ctx = getFacesContext();
        Application app = ctx.getApplication();
        ValueBinding bind = app.createValueBinding("#{row.space_separated_attr_from_DB}");
        String space_separated_attr = (String)bind.getValue(ctx);
      // now, parse space_separated_attr, store in the ArrayList, and return as method result:
      return some_parsed_ArrayList; // you know...
  }
  
  private ArrayList listTest = new ArrayList();
  
  public void setIterTest(ArrayList listTest){
        this.listTest = listTest;
  }
  

  Then place new column in the af: table, as follows:

  This way, you'll have a commandLink for each word of space_separated_attr_from_DB

  Here is how this looks to the execution time:

  

  

• Error using groovy to fill the transient attribute

  Hello

• Calculation of sum in the attribute of the entity

  Dear all,
  
  I have following the entity attr.

  <Attribute
      Name="TotalAppraisedIncome"
      ColumnName="TOTAL_APPRAISED_INCOME"
      SQLType="NUMERIC"
      Type="oracle.jbo.domain.Number"
      ColumnType="NUMBER"
      TableName="z_z"
      IsQueriable="false"
      RetrievedOnUpdate="true"

      </DesignTime>
      <TransientExpression><![CDATA[adf.object.IncomeDetailSummary_VO1.sum("(AppraisedIncome/100)*IncomeCombination")]]></TransientExpression>
    </Attribute>

  The problem is that it does not display the design for attribute value, betai I created the accessor to view in the attribute of the entity.
  
  But when I use it in viewobject as transitional attribute, it works very well...

  <ViewAttribute
      Name="TotalAppraisedIncomeView"
      IsSelected="false"
      IsPersistent="false"
      PrecisionRule="true"
      Type="oracle.jbo.domain.Number"

      <TransientExpression><![CDATA[IncomeDetailSummary_VO1.getRowSet().sum("(AppraisedIncome/100)*IncomeCombination")]]></TransientExpression>
    </ViewAttribute>

  I need to do at the level of the entities because the value is caluclated runtime and it should be updated in the field of database corrosponding.
  
  Any ideas?

  Hello

  based on a usage example Dept/Emp in human resources

  1 create EO departments and employees EO with Department/employee Association (master / detail)
  2. search the name of the Association (in my case employees) end in detail
  3. create a transient in EO departments attribute - say 'SalariesPaid '.
  4. create a class Impl (EmployeesImpl and make associations that are exposed as methods)--> getEmployees1 in my case
  5. use the following expression Groovy on the transient attribute

  adf.source.getEmployees1 (.sum ('Salary'));

  ... or whatever the mathematics you need to perform

• VO extension: Transient attributes not getting seeds not filled

  Hi gurus,

  I expanded VO by adding two additional columns (questioned). Even if the new columns and surveyed existing columns are coming fine on the page, the calculated columns return null.

  Calculated columns are populated in the VORowImpl code seeded of the VO seeded. I'm missing something here?

  see you soon

  Anish.

  Hi Anish,

  If the transient attributes will be populated in the VORowImpl, you must copy the logic in the extended VORowImpl or call the same method using super.

  ex: -.

  Standard VORowImpl

  public String getAttribute1()
  {
     return "Calculated Value";
  }
  

  VORowImpl extended

  public String getAttribute1()
  {
      super.getAttribute1();
  }
  

  See you soon

• Programatically set passivate = true on a transient attribute

  Hello

  Generate us the xml viewDef data programmatically and must assign passivate = true on a transitional attribute. No idea how to do this?

  Jdev version - 11.1.1.7.2

  Thank you

  R

  How to create your Def VO? You can use the ViewDefImpl.setPassivationMode () method to set the mode of passivation at the level of the VO. For example, you can set the mode of passivation to "Passivation, including all of the transitory values" by invoking the following:

  this.setPassivationMode (PASSIVATE_TRANSIENTS_TOO);

  If you want only some of the transient attributes, passivation, so if you add a custom property to the AttributeDefImpl (s) corresponding with name equal to ViewObjectImpl.XML_ELEM_PASSIVATE_TRANSIENT and one value other than 'false', the framework will passivate these transient attributes:

  attrDef.setProperty (ViewObjectImpl.XML_ELEM_PASSIVATE_TRANSIENT, "true");

  Take a look at the method undocumented scope of package ViewAttributeDefImpl.isPassivatableTransientAttribute () for more details.

• Check if there is a transient attribute in 10.1.2

  Hi good ppl
  
  We have an old application using BC4J - 10.1.2 and noticed that [AttributeDef] doesn't have the isSelected() method that could help me to differentiate the transient attributes. Is there a solution for this? I need to isolate the transient attributes from the rest, without test manually by report name (if another developer adds a transient attribute tomorrow, I can't wait for the change must be made in all the places where we test "is TransientAttribute").
  
  Thank you...
  K

  Hello!

  You can use AttributeDef.getAttributeKind (). If the byte returned is AttributeDef.ATTR_TRANSIENT the attribute is transitional.

• Small problem of calculation for the size of the Page when using overflow online

  Hello world:
  
  It seems to me that in 11g when I use:
  
  (1) a presentation of table form
  (2) overflow online
  (3) calculate the width of the Table
  
  The calculation does not take into account the width of the "twistie" as I call it, which is a small triangular arrow pointing at the time where there is something to the overflow inline and points downwards when you look at what is in the overflow online.
  
  Pages that have these 3 features have a scroll bar on the bottom, which needs a little more room. I guess that's the width of "twistie" is not taken into account.
  
  I looked on this forum as well as the Release Notes to see if it was a known problem, but did not find, and I can send you a unit with the HRSchema test, if you want to.
  
  I realize that I can use the "pixels" instead of calculating the width of the Table, but I thought I should report it to you if you didn't know already.

• Transient attribute based on the selected query by using a function call

  Hello

  Post version is 11.1.1.7.0 JDeveloper.

  I'm not able to get the following work properly;

  1. I have a scenario header / detail.
  2. Calculate a value for each row returned detail that I find. This calculation is done using an existing database to function.
  3. The function requires 3 input parameters.
  4. Two of these parameters can be retrieved in the detail row and one is a value which is on the header.
  5. I created a transient attribute on the object of the detail view and selected the following properties of the 2 attribute;
     1. Mapped to the column or SQL
     2. Selected in SQL
  6. I entered the following SQL Expression;
     1. function_name (DetailTableAlias.value1, DetailTableAlias.value2, ViewLinkName.value3)
  7. Running AOS that contains the objects of view header / detail, I encounter a SQL error which indicates that ViewLinkName.value3 is an invalid identifier.
     1. I can understand why this error occurs.
  8. If I change the ViewLinkName.value3 to a literal value, the error will not occur.

  So, my question is how can I pass the third parameter to the transitional attribute database function call as the value literal and not as a reference to one, missing attachments header table, column?

  Concerning

  Leon.

  Hi Leon

  Have you explored solve this by an inline SQL query to derive the 3rd parameter of the function? In other words, the problem in SQL instead of ADF.
