What is good use of the getKey() to set the current line - jdev 11.1.2

Hello:

GetKey() seems to come back oracle.jbo.Key [106]

The primary key is 106, but how do you home? Here is my code:

In the iterator, I have:
Key = rw.getKey ();
System.out.println ("Key =" + Key); displays key = oracle.jbo.Key [106]


I'm doing something wrong. What is the correct usage? I want to set a different iterator to the value of this key is 106
and run a query.


= code below =.

Hello

you think you're doing here?

Integer keyInt = new Integer (key.toString ());
iter.setCurrentRowIndexInRange (keyInt);

A key is not an index of the line. Thus, instead of you call

iter.setCurrentRowWithKey (key.toStringFormat (true));

    Hi joej49728017,

    I'm sorry for the inconvenience caused. But it's all just because Adobe Acrobat 7.0 is a stale version & now the activation server so that there is no.

    Please refer to the following KB doc.  Error: "Activation Server is not available. CS2, Acrobat 7, pass a hearing 3

    The link above will help you to install a special version that doesn't require activation.

    In case you still need assistance, please let us know. We will be more than happy to help you.

    I added 2 buttons create insert and delete. So am clicking the button always delete the first row is deleted. I need to remove exactly same line of an iterator.

    If you use an iterator, you will need to provide the current line yourself. If you use an af:table the table handles it for you.

    You can use an af:setPropertyListener on the buttons push the PK line to a variable binding, or a bean as

    in this case, row.id is the pharmacokinetics of the current line and bean.currentRowId the bean property save you the row id when the button is clicked.

    In the removal and the method use then the currentRowId to search for the line and delete it.

  • How selectBooleanCheckbox can set the current line?

    Hello

    Using ADF Faces 10 g, I have an af:table component that is read-only, but the last column contains an af:selectBooleanCheckbox. This checkbox is used to 'activate' and 'disable' to each line. When I click on the box, I need the valueChangeListener be aware which line has been activated (so that I can then make some changes on this line to toggle). By clicking on the box to check must call setCurrentRow, or at least pass on values I can use later to set the current line manually.

    My first thought was setActionListener, but it seems that it may not be combined with af:selectBooleanCheckbox. I searched and found the following post:
    HOW to set an ID for the component from variable
    and after reading this I tried setPropertyListener, once again, I found that this is not a valid child of af: selectBooleanCheckbox. The post dry with nuansantio mentioning several times that setActionListener and setPropertyListener cannot be used, but there is no other comments on a solution.

    Any thoughts on how I can get this to work?

    Hello

    Could you elaborate more about

    I need to make a number of manual steps (invoking request Module) when the user selects / disables the check box

    You can pretty much add a method in your Impl VO (who did all the steps you want to do) and call the method in an expression for the value of groovy / call it in valueChangedListener of the box?

    Y does it have that in any way the security of the network is compromised PURELY through the use of telephone landlines?

    Is there a way to "trap"? For example, giving the command remotely to a computer (trap) the property of Microsoft or the FBI or... ? I bet that someone wants to catch them? I wouldn't mind redirecting their...
    If they keep the call, he must mean the scam work and the people in the fall.

  • How to get the current line or the entire paragraph?

    Hello.

    I am facing the following problem:

    Suppose I have the following in FrameMaker:

    It is a sentence. And (end of single line)

    There also this sentence. (end of paragraph)

    It is a sentence. And (back)

    There also this sentence. (end of paragraph)

    It is a sentence. And (end of single line)

    There also this sentence. (return)

    But there is also this sentence (end of paragraph)

    It is a sentence. And (end of single line)

    There also this sentence. (return)

    There also this sentence. (return)

    But there is also this sentence (end of paragraph)

    What I want is this:

    Download the text of the entire paragraph where the insertion point of the cursor is.

    However, when exist from the ends of the hard line I want to change their behavior.

    This is the behavior to the foregoing:

    For the first example of the paragraph if the cursor is either first or second line I want to get the whole paragraph.

    Paragraph if the cursor is in the first line, I want only the first line. And if it's in the second row, I want only the second line.

    The third paragraph if the cursor in the first or second line, I want the first and second lines must be retrieved in plain text. Also, if the cursor is in the third line I want only to the third line.

    For the fourth paragraph, it functions as the third paragraph. If the cursor is in the third row I get only this one.

    Could you please provide of the FDK in C++ to start with code?

    It's a puzzle.

    As you are in the forum script, I am related to this here. You must understand the FDK C++ code yourself.

    There's not much to tease my brain with it. You get the point where the cursor is and pick up the pieces of text more line via the GetText() method, using a bit field which includes the FTI_String and the FTI_LineEnd. Each end of the line has a modifier that tells you if it's a hard or a return. You also get the offset in the paragraph of the current position of the cursor, and then create the necessary strings from the array of items of text returned by the GetText method.

    If you want the full execution of the code, ask someone to program it for you and be prepared to pay for the work.

    Good luck

  • How to manage the current line with radio button selection?

    Hello world

    I have an ADF page with a table and a search"" button.
    I created a new attribute with VARCHAR2 (1) in the VO and dragged this attribute as the first column of the table. And changed this first column of the option button to select only a single line at a time.
    By clicking on the "Search" button, I need to get the current selected row values.

    How can I get the values of selected line?
    What code should I write to get the values of the selected line in the method of binding the button 'search '?

    All suggestions will be really useful.

    Thank you.

    Hello Kumar,
    I have a few comments on your case.
    >
    I created a new attribute with VARCHAR2 (1) in the t
    >
    1. you should create this attribute in the object of the entity, and then add it to the view object.
    2-do you need this radio that a button is defined for all lines? If yes then you need handle the case where the user set several lines and clear the value of the attribute for all other lines.

    How can I get all the values of the current row in backing bean, binding of the Find method (method)?
    can u please give me the code for this?
    >
    If you mean by the current row is the row for which the value of the selected attribute is defined (the radio button is set to the rank), then you can write a method in the viewObjectImpl class and expose it to the customer interface and call it from your bean.
    Here is a sample Department table in the HR schema.

    //This method is written in DepartmentsViewImpl
    public Row getSelectedRadioRow(){
                //create a second row set to not impact the row set used in ADF
                RowSet duplicateRowSet = this.createRowSet("duplicateRowSet");
                //get the current row of the table to set it back after re-executing the VO
                DepartmentsViewRowImpl currentRow = (DepartmentsViewRowImpl)this.getCurrentRow();
                Row[] filteredRows = duplicateRowSet.getFilteredRows("IsSelected", "1");
                DepartmentsViewRowImpl row=null;
                if(filteredRows.length>0){
                    row = (DepartmentsViewRowImpl)filteredRows[0];
                    System.out.println("Department Name " + row.getDepartmentName());
