• How to have a dynamic number of tables where new rows can be added

  Hello
  I'm new to ADF and have a task where I on a single page should I show that a dynamic number of tables and each table below should show some fields and create a button to create new lines in the table. To be more precise each table show an education for the individual and the rows of the table shows the meanders of specific education.
  I thought to use a treetable but don't think it's the right way to go because of the new line add feature - I'm not sure of the combination of having a dynamic number of tables and the ability to create new lines of each table.
  If you know where I can find a model similar to the one above or just give me your opinion on how to solve it, it would be much appreciated.
  I get the data from a Web service.

  This is a small sample.

• Dynamic number of columns in the table

  Hello
  
  I use JDev 10.1.3.3.0 with ADF. I just want to create a table, with a dynamic number of columns in the table. The background is that a user of my webapplication can create and submit a sql query. Now, I have to show him the results. My idea was, I have save the result in a bean managed (ResultTable), which is stored in the session context and map at my table in my page.
  
  If I search the Forum and don't get only one useful thread: {: identifier of the thread = 971888}, but I don't exactly understand. What is the CollectionModel? Do I need this?
  
  I'm trying to report on the following:
  
  ResultTable

  public class ResultTable {
  
      public static final String SESSION_NAME = "ResultTable";
      private ArrayList<ResultColumn> columnList; 
      private CollectionModel collectionModel;
  
      public ResultTable() {
      }
  
      public ArrayList<ResultColumn> getColumnList() {
          return columnList;
      }
  
      public void setColumnList(ArrayList<ResultColumn> columnList) {
          this.columnList = columnList;
      }
  }

  ResultColumn

  public class ResultColumn {
      
      private ArrayList<ResultRow> rowList;
      private String name;
  
      public ResultColumn() {
      }
  
      public ArrayList<ResultRow> getRowList() {
          return rowList;
      }
  
      public void setRowList(ArrayList<ResultRow> rowList) {
          this.rowList = rowList;
      }
  
      public String getName() {
          return name;
      }
  
      public void setName(String name) {
          this.name = name;
      }
  }

  ResultTable

  public class ResultRow {
      
      private String value;
  
      public ResultRow() {
      }
  
      public String getValue() {
          return value;
      }
  
      public void setValue(String value) {
          this.value = value;
      }
  }

  My showResult.jspx

  <af:table emptyText="No items were found"
            value="ResultTable.columnList"
            var="column"
            varStatus="colStatus"
            id="table1">
    <af:forEach items="#{column.rowList}" var="row" varStatus="rowStatus">
      <af:column sortable="false" headerText="#{column.name}" 
                 id="column#{colStatus.index}">
        <af:outputText value="#{row.value}"
                       id="outputText#{rowStatus.index}"/>
      </af:column>
    </af:forEach>
  </af:table>

  The ResultTable was filled with data, but the Board is not filled. So, I think, it must be rejected to the data binding.
  
  I get warnings and errors to run too. But I don't know if they are the result or cause of my problem.

  Hi Mario,.

  Note that your JSPX snippet above has serious shortcomings:
  

• 'ResultTable.rowList' is not an EL expression, but the value attribute of the af: table must refer to an EL expression
  
• Items AF:foreach = "#{row.cellList}"-you don't have to store information about the columns of all rows, more it won't work as af:forEach tag may not see the value of the expression of EL #{line} (or any component EL expression created). " See the tagdoc here: http://www.oracle.com/technology/products/jdev/htdocs/partners/addins/exchange/jsf/doc/tagdoc/core/forEach.html
  
• "ID =" Column #{cellStatus.index} "and id =" outputText #{rowStatus.index} "are invalid and that they don't compile even as id attributes cannot contain EL expressions.

  .

  I think to solve your problem, you need three things:
  

• List of columns (for example the list If you need to store only the names of column or list If you need additional information),.
  
• list of lines,
  
• a line can be a map (with the name of the column - cell data mapping; card e.g.) or a list (with columns indexed; for example

• ADF trigger dynamic number of components

  I have an addiction to view object class three levels-> category-> subclass and want to create a dynamic form with the following logic:
  When the user selects a category drop down, page is updated with a number of drop-down lists of class with all subclasses - that is, I have a dynamic number of components selectOneChoice depending on the category selection. Dependence of the class category is implemented with valueChangeListener category Classes of queries with the category Id, class subclass is simple link display / tree of the value binding. Value of subclass for backing bean binding is done with a hash table.
  
  ADF faces framework let me recreate the elements of the actual page with partial-page rendering (or some other mechanism)?
  Should I completely re - generate all the components of selectOneChoice inside forEach whenever the user changes category.
  
  
  My components in the page:
  
  
  < af:selectOneChoice value = "#{bbean.category} '"
  label = "category".
  autoSubmit = 'true' immediate = "true".
  ID = 'category' valuePassThru = 'true '.
  valueChangeListener = "#{bbean.categoryChanged}" >
  < f: selectItems value = "#{bindings." Categories.Items} "/ >"
  < / af:selectOneChoice >
  
  
  < af:forEach var = 'class' items = "#{bindings." Classes.Children} ">"
  < af:selectOneChoice value = "#{bbean.subclass [class.id]}" "
  label = "#{Class.Name} '"
  partialTriggers = "category".
  ID = "class" valuePassThru = "true" >
  < af:forEach var = "subclass" items = "#{class.children}" >
  < af:selectItem label = "#{subclass.name}" value = "#{subclass.id}" / > "
  < / af:forEach >
  < / af:selectOneChoice >
  < / af:forEach >
  
  
  
  The above code is a development of earlier less complex UI. For everything I tried I can't get to the desired effect. When I change the category it does not affect sub-drop downs somehow. If I activate the valueChangeListener category, category change cause the validation phase null property exceptions:
  
  2.9.2008 14:05:40 com.sun.faces.lifecycle.ProcessValidationsPhase run
  SEVERE: Error test 'null' property at the bean of type my.project.view.managed.Search$ 1
  javax.faces.el.PropertyNotFoundException: error test 'null' property at the bean of type my.project.view.managed.Search$ 1
  ...

  Erik,

  Instead of making components selectOneChoice have 'category' as their partial triggers, what happens if you set partialTriggers = 'category' on a parent of these selectOneChoices component?

• Covert rows to columns dynamically

  Hi Experts,
  
  I use oracle 10g and do not have access ' t create/write on it so I can't create a view/procedure I want to achieve the next thing with a single query.
  
  I have the table like this
  
  Name of the value ID
  
  1 - ONE - AS
  1 - B - ACE
  2 - C - BN
  2 - D - BN
  2 - E - NL
  3-F - CV
  3 - G - CV
  
  and want to have result as below
  
  ID -- AS -- BN -- CV
  1 -- A,B --- --- --- ---
  2-- --- -- -- C,D,E --
  3 --- --- -- -- -- -- F,G
  
  Here I used '-' for the space.
  
  I was able to achieve this result by using the following question
  
  SELECT id,
  MAX (DECODE (NAME, 'LIKE', VALUE, NULL)) AS «DO»,
  MAX (DECODE (NAME, 'NL', VALUE, NULL)) AS 'BN ',.
  MAX (DECODE (NAME, 'CV', VALUE, NULL)) AS 'CV '.
  (SELECT ID,
  RTRIM)
  XMLAGG (XMLELEMENT (e, VALUE |)) ',')). EXTRACT ('/ / text()').
  ',')
  VALUE,
  name
  TEMP
  Doc_rno, name)
  GROUP BY id
  
  But here I am hardcoding 'THAT', 'NL', 'CV' column name so that could generate the result.i wants to reach without hard-code the name of the column because I'm having dynamic value in the name column.
  
  for example
  
  for A database its going to be W, R, T
  for database B its going to be C, K, L, P
  
  even I do not know the values in the name column
  
  could someone help pls it's very urgent.

  DROP TABLE T;

• Selection of column dynamic Collection

  Hi gurus,

  I have a little problem with a collection.

  I have a collection with a type of pins. The selected cell may contain 28, 29,..., 33.

  Later, I want to count the lines of the following collection, where (in this example) c033 is not null. The variable is then used as a string, not a column.

  How can I use the variable as a column in the 'where' - clause?

  Here is my sql query:

  declare
  l_type_position varchar2 (4);  -content will be: c033
  l_types number (3.0)

  Start

  -Select the dynamic column for the next newsletter

  Select 'c0 ' | (c009) - c009 = 33
  in l_type_position
  of apex_collections

  where collection_name = "UPLOAD_HEAD";

  Select count (l_type_position)
  in l_types
  of apex_collections

  where collection_name = "SPREADSHEET_CONTENT."
  -folowing line error occurse

  and l_type_position is not null;   -= and c033 is not null;
  
  end;

  Thanks for help.

  This can be done using lexical replacement and dynamic SQL (as always, check for possible code SQL injection):

  declare
  
    l_type_position varchar2(4);  --content will be: c033
    l_types number(3,0);
  
  begin
  
    -- select the dynamic column for the next statement
    select 'c0'||(c009)   -- c009 = 33
    into l_type_position
    from apex_collections
    where  collection_name = 'UPLOAD_HEAD';
  
    -- check for SQL injection
    l_type_position := dbms_assert.simple_sql_name(l_type_position);
  
    -- count collection rows
    execute immediate q'{
        select count(}' || l_type_position || q'{)
        from apex_collections
        where  collection_name = 'SPREADSHEET_CONTENT'}'
      into
        l_types;
     ...
    end;
  

  However, it is possible that it is a question of XY. If further information on the nature of the obligation provided that it might be possible to identify a clearer and more secure solution using SQL static.

• Create columns dynamically

  Hello
  
  I'm writing an application that contains a table to display data from a file. I want to know the number of columns of data in the file, because it can vary. However, it seems that I might have a problem with the creation of methods setter/getter for properties of column as I don't know before hand the number of columns and what called I make use of PropertyValueFactory class of convenience because it uses a channel set for a parameter.
  
  Any suggestions?
  
  Thanks in advance

  You can use a list<> or ObservableList<> data for each line of the table type (thus table.getItems () will look like ObservableList<>>.) You will not be able to use a PropertyValueFactory: you define a CellValueFactory custom columns to be indexed in the correct column.

  Here is an example that reads a tabs-delimited text file and populates the table on the fly. Eventually, it reads the first line as "header values" (i.e. of the column titles) and then each line. If a row has more columns that are currently in the table, it adds additional columns. Analysis of tabs is not intended to be the quality of the production (without tab quotes are supported, etc.).

  Enter the URL of a tabs-delimited text file and press ENTER to see work. (If you have a folder on your file system, use file:///absolute.path.to.file.txt.)

• Create a column of number starting at a variable

  I want to create a column on a report that will number the lines sequentially starting at an input variable.
  
  Production is expected to be something like the following if 100 was entered as a variable starting:
  
  100 first line details
  101 second line details
  102 third line details
  
  
  The variable should be entered as a parameter.

  Hello
  In case the solution given by Rod does not work, perhaps because of sorting you can try this:

  1. create a calculated item, say called BASEVALUE and enter 1 for the calculation

  2. create this second calculation:

  * Sum (BASEVALUE) (ORDER BY sorting your items LINES UNBOUNDED PRECEDING) + variable departure*, so if your sort were growing sorted POINTS and MYDATE down with a 500 starting point it would be as follows:

  SUM (BASEVALUE) OVER (ORDER BY ASC, DESC MYDATE ROWS UNBOUNDED PRECEDING ELEMENTS) + 500

  3. remove the spreadsheet BASEVALUE so that it does not appear

  Best wishes

• Dynamic number of panelBoxes in panelDashboard

  Hello
  
  I had a scenario where I need to display a series of images in a particular order as a string. When the length of the string is greater than 5, he can display them in the rank, but only in the order of the string, and also the number of images is decided during execution.
  
  So I thought with the use of the panelDashboard with panelBoxes inside, which can be organized running using the columns: 5 of the panelDashboard . But I'm not able to use the af: forEach inside the panelDashboard. This prevents me from doing a dynamic creation of the panelBoxes.
  
  So somebody please give me a way to do it... or a better way to meet the requirements

  Hello

  Have you tried to run the page regardless of the error? Just tried with

  And be able to see 5 panelBoxes inside panelDashboard.

• How to set the page dynamically number in a URL?

  Hi, I would like to know how to dynamically set the number of pages in one URL. I have a report that shows me a list of options, and each option has a specific associated page number. I would like to redirect the user to a specific page, depending on the option, click it. (The values of the elements of the report, comes from a table that has two columns: opinion on, page_name)
  
  Thank you

  Just do the report column a link (in the attributes report > column attributes) and change the target to a url. The url should be something like

  f? p = 1: #MYPAGENUMBERCOLUMN #:Session:Request:Debug:Clearcache:itemname:itemvalue:printerfreindly

• Ability to pass dynamic number of entries to a procedure using native SQL?

  Hello

  We have end users to do things like this:

  var x refcursor;

  exec some_proc (1234,: x);

  print x;

  Now, they want to use dynamic multiple entries like this:

  var x refcursor;

  exec some_proc (1234 5678, 9011,: x);

  print x;

  Yes I know you could do something like this:

  Create the type t_num is table of number;

  declare

  v_nums t_num: = t_num (123,456,789,234);

  v_result sys_refcursor;

  Start

  some_proc (v_nums, v_result)

  end;

  But they have some old piece of middleware simplifying procedure calls which it can handle data types and cursors.  So I was wondering if there is a way to fill a cursor using native sql to succeed in a procedure?  Yes I am assuming that the answer will be no, but I wanted to just make sure.

  But they have some old piece of middleware simplifying procedure calls which it can handle data types and cursors.

  Too old to take a string delimited as input?  Then cut the string and fill it with v_nums in some_proc?  Does not seem a lot of work.
