• How to check the number of "empty" field

  Hello world

  I describe the situation as a first step:

  • I work with WCC 11.1.1.5
  • I have workflows 5 steps.
  • Users can change the values of the attributes of document at each stage.
  • I managed the attribute is required in each step by rules. The attributes are not defined as ' required value: required ' by attribute definition. It is done by the definition of the rule.
    

  
  

  What I do:

  Check that one attribute (called xInv_SAP_document_line) has been filled in by the user in the third step of the workflow. This attribute is of type 'Integer '.

  
  

  What is my problem:
  

  Whenever the system performs the update of sending it automatically fills the number 0 for all integer attributes.

  When the user fills out a "xDepartment" attribute in the first stage, the system to insert a value of 0 for the attribute 'xInv_SAP_document_line '.

  I'm not able to verify if the user filled in the "xInv_SAP_document_line" attribute in the third step, because the value 0 is already there from the first step. It has no effect if the attribute is 'Required' - it has value = it's OK. But I need a control that the user fills out. Not the system.

  
  

  What I tried:

  'Use the default' check the box help doesn´t rule field. It only works for empty values.

  I can change the value of "derived field" checkbox in the second stage. But I'm not able to erase the value - what is the behavior I need.

  
  

  Is it possible to remedy this situation?
  

  
  

  Thanks for any advice,

  Mike
  

  
  

  
  

  
  

  Integer fields, once submitted, will be filled with 0 when the element is submitted and the field is empty.  It's the way integer fields work in Content Server - I've not seen a way to change this behavior.

  If 0 is never going to be a valid value, in the article "side effects" of the rule, add the following code and see if it solves your problem.

  <$if #active.xinv_sap_document_line="=" 0$="">

  <$dpPromote("xInv_SAP_document_line","")$>

  <$endif$>

  However, the window filled with information from the record 1. and when I select a record in the table and click on the popup, the popup is filled with this record.
  How can I make the popup with empty fields and create a new record by recording the popup?

  You must call the CreateInsert for the underlying ViewObject operation when opening the popup because it does not allow to clear the input field, you must have a new record created

• How to set the value of a field from the LOV of another field.

  I'm trying to figure out how to set the value of a field (P_PROGRAM) to the value of another field of based lov (P_STATE).
  
  The P_PROGRAM field is a hidden field. The P_STATE field is a required field and is based on a list of values for the State Codes.
  
  When a user selects the State to P_STATE, the field of the P_PROGRAM should be set to this value, as well.
  
  I tried different ways to get there via a function call on the post for the calculation of the field P_STATE, defining the source P_PROGRAM to the value of the page item P_STATE put varialbles, creating a process before SENDING, and they all still come back as having a NULL value for P_PROGRAM, therefore impossible to create the file in the db as the PROGRAM is a mandatory field in the table.
  
  Can you please help? Thank you, Laura

  Laura,

  It is always helpful if you provide information about the Apex version you are using. The Apex 4 you can use Dynamic Actions to achieve this. In earlier versions is possible using processes to submit or javacsripts, as well.

  Heres how you do in 3.x with treatment to submit, to make it work in 4.0 as well.

  1 do the P_STATE ' select list submits the Page.
  2. Add a calculation on the point P_PROGRAM, or write to him assign a value based on a process. The treatment should be OnLoad after the header
  3. If the page does not have an unconditional branch that loops on itself, add a. NOTE: The direction must be the last branch (larger sequence number) and should have checked "Save Session State".

  This is what will happen
  a. when the State is selected Page will be submitted
  (b) it will take the unconditional branch to himself and save the value of P_STATE
  c. the calculation process / fills the value of the P_PROGRAM element when the page reloads

  Kind regards

• How to handle the onTriggered many ActionItem created dynamically

  Hi, I created the ActionItem dynamically using (loop)

  because data is from webservice

  How to handle the onTrigerred?

  If my code is like this:

  for (int i = 0; i)< alist.count();="">

  {

  My page page * = iRoot-->findChild ("SpecificObject");
  ActionItem * action = ActionItem::create () .title (aList [i] .name);

  bool res = QObject::connect (action, SIGNAL (triggered ()), this, SLOT (handleAction (())); what I'm confused because I don't know what action is triggered
  Q_ASSERT (res);
  Q_UNUSED (res);

  my page-> addAction (action, ActionBarPlacement:efault);

  }

  MyClass::handleAction() Sub

  {

  aFunction(); This parameter of function required of aList, said user.user aList [i]

  }

  Do I need to create handleAction() as well as added actionItem SLOT

  But I don't know how much action added because it is dynamic server

  Thank you

  There are a few options:

  Create a single location and connect all the signals. You can then call sender() into the slot to retrieve the object that sent the signal and go from there. You can also use a QSignalMap that maps each signal to a value and send this value to a single location. You can also use QSignalMap::sender() to get the sender object.

  I used the QSignalMap to do something similar for handling created dynamically successfully drop-down lists.

• How to change the color of form fields

  I don't know how to change the color of form fields. They default to gray, but I don't know how to make a different color.

  Gray does not match the color scheme of my landing page!

  Thank you!

  I think you have two options when you are working on a landing page with an embedded format:

  • You can change the background color of the entire form field set by selecting the shape, and then clicking on the Toolbox. In the window that opens go to the second (on a paint brush icon) and select the background color you want.
  • You can change the background color of the actual fields in the form by adding CSS styles. Select the Toolbox, go to the last tab (Tools Extract page) and in the middle of this window, you will see "head | CSS | JS"- select this average CSS tab and enter the style code to get the color you want. Here is an example of code you can put in it. Note that #000000 is the color code for black. Here is more information about the code: css - background in the input fields and text color? - stack overflow

• How to adjust the display width of fields?

  work in jdev 11.1.2.3.
  the form looks like DESIGNER Visual, all fields of the same length, and there is no width attribute to adjust. When run, some too long display fields.
  How to adjust the display width of fields in the design?
  Thank you.

  Hello

  You don't need to repeat once again, unless you have changed the properties after initial drag and drop.

  If you have changed, use the value #{bindings.yourAttribute.hints.displayWidth} to the columns property.

  
  label = "#{Bindings.Name.hints.label} '"
  required = "#{Bindings.Name.hints.Mandatory} '"
  * Columns = "#{Bindings.Name.hints.DisplayWidth}" *.
  maximumLength = "#{bindings.name.hints.precision} '"
  shortDesc = "#{bindings.name.hints.tooltip}" id = "it38" > "

• [JDev12c, ADF] How to get the value of a field from the selected line in af:table and...

  Hallo,

  I want to double click on a line of an af:table to call a page that displays a form (based on a View object) with the details of the selected line.

  I need to go to the second page the value of a field on the line that is selected on the first page.

  How can I do this? In particular, how can I get the value of a field from the selected line? How can I call the second page on double-click on the af line: table?

  Thank you

  F.

  Why would user, you need to pass a value of the line to the shape?

  The framework selects the line you want to display in the form. All you have to do is to show the form with the selected line. It is the framework automatically as long as you use e vo even the same data control.

• Officepro HP 8600: How to bypass the color cartridges empty on my HP Officepro 8600 to print only in black

  I am wanting to print Grayscale / black only, still does not allow me to print because I have empty color cartridges.

  How can I get around this?

  I tried changing the settings

  Thank you very much

  While printing in black is only an option when the color is low, it is blocked once a cartridge is exhausted.  You will need to replace the depleted cartridge. Page 94 of the said the manual here:

  Printing in black ink or color only

  For regular use, this product does not print using only the black ink cartridge when the color cartridges are out of ink. However, your printer is designed to allow you to print as long as possible when your cartridges are starting to run out of ink.

  When there is enough ink in the print head, printer will offer you the use of black ink only when one or more cartridges color is out of ink and color ink usage only when the black cartridge is out of ink.

  • The amount that you can print using the black or color ink is only limited, so the available spare ink cartridges when printing in black ink or color only.

  • When it is no longer sufficient ink printing, you will get a message from one or more cartridges are exhausted, and you need to replace the depleted cartridges before you resume printing.

  HP and other printer manufacturers have technology another printer for different needs.  For ink jet printers:

  • Some have integrated into the ink cartridges print heads.  These printers can print generally with one or more of the colors completely empty, or even with color or black cartridges (but not both) removed. The 8040 a Officejet is an example.
  • Other printers have separate replaceable printheads and inks.  An example would be the printer Officejet Pro 8600.  In these printers print head can be replaced if they are damaged by running the printhead with colors off.  Some of these printers allow printing with a color, the other will not.  If the printer is run without ink in one or several colours, the printer may be damaged, but the user may be able to recover without having to send to the printer for the service.
  • Other printers have permanent print heads.  To run only those without little ink in all colours would risk causing damage to the print head because of clogs, air ingested in the printhead or grilled printhead resistances of shooting. The Officejet 6700 is an example of this type of printer. For printers with fixed print heads that could require the service to get the printer to print properly again when the ink is finally replaced.

  The document described here how the ink is used.  The document is written for inkjet printers HP the same principles apply to printers inkjet from other manufacturers.

  If you do ever print color laser printer would probably be a better choice.  If you occasionally print color but especially black a HPI printer as those in the first category above can be a good choice.

• How to upgrade the height of a field after painting?

  Hello world!

  Here's my question: I implement my own domain with the following components:

  A text which may be multi-line

  A second text which may be multi-line

  An image with a fixed height (80px)

  When the getPreferredHeight() substitution, I don't know the future height of my area (which depends on the multiline settings). So I would update the height of my field after the painting process, while it takes only the necessary height.

  How is it possible to do?

  Thank you in advance.

  OK, I did so using a prepareLayout() method in the constructor as computs the width and height of the next field.
