• Problem with the Paging in VO tuning range

  Hi all
  
  I am having some problems with the Range Paging in VO tuning. My VO questions about 5000 + lines. So I'm going to the range of paging that is the recommended method for managing large data. Here I must also get the current row of the table (which shows the desired result). But when I use the getCurrentRow() method, it results in a value zero. Why this happens?
  
  code
  FacesContext fc = FacesContext.getCurrentInstance ();
  Object returnObject1 = null, fc.getELContext () .getELResolver () .getValue (fc.getELContext (), "links");
  DCBindingContainer bindingsIte = returnObject1 (DCBindingContainer);
  DCIteratorBinding dciter = bindingsIte.findIteratorBinding("ClientsVO1Iterator");
  Line rowClient = dciter.getCurrentRow ();
  String sDisposaltype = rowClient.getAttribute("DividendDispType").toString ();
  
  This method works very well with the scrollable access mode.
  Is there a special way to get the current line with the range Paging?
  
  Thank you
  Danesh

  Danesh,

  I have not checked this version or the most recent 11.1.2.1, but in 11.1.1.4, we had this problem and we use workaround:
  1. remove the current selectionlistener in the table (#{... makecurrent}).
  2. set a new headset selection (using the small arrow to the right) in a bean of your choice. The scope of the bean must be seen or pageflow depending on where you need access to the selected line.
  3. in the new selectionListener you get the selected line of the event, get the key in the line and store in an attribute of bean
  4. to the point you need the selected line, you use the stored line button and work with that. If you need attributes from the line you must ask for the line, once again, that you only the key. In our case only pass us the key to a service in the module of the application method, so this works very well for us.

  Here is an example of such a selection listener

      public void singleSelectionListener(SelectionEvent selectionEvent)
      {
          RowKeySet rksAdd = selectionEvent.getAddedSet();
          if (rksAdd.isEmpty())
              return;  // no selection
  
          Object[] it = rksAdd.toArray();
          // as this is for single selection there should only be one, but...
          for (Object obj: (List) it[0])
          {
              mLogger.fine("Selected :" + obj);  // log selected row
              Key k = (Key) obj;   // the object is the row key
              Object[] kv = k.getKeyValues();  // get the key value for later
              // strore the key value in a bean attribute
              mLastSelectedOID = (Integer) kv[0]; // store the key value (if the key has multiple parts you need to store them all)
          }
      }

• What is the difference between ActionEvent and SelectionEvent?

  Technical environment:
  Oracle jDeveloper 11.1.1.4.0
  Windows XP
  ----------------------------------------
  
  I think there is something behind ActionEvent and SelectionEvent which makes my code does not work.
  
  Here's my problem:
  
  I have three tables. One is a masterpiece, contains the summary of something. If I select a line on this chart, the second table shows some data, based on the line selected on the first table. Well Yes, it is a ViewLink, and it works perfectly. Now, I want the same thing to work between the second and the third table. If I select a row in the second table, the third table should show some data, based on the line selected on the second table. The third table is a ViewObject with some binding settings. I need to assign values to these parameters, that I get the value of the line selected on the second table. How can I do this?
  
  I tried to use ExecuteWithParams. Select the line in the second table, get the values, pass it in the form ExecuteWithParams, run and... it works... I get the result on the third table. Here is the code how to:
  
  ***
  {} public void updateTableEvent (ActionEvent actionEvent)
  DCIteratorBinding iter = gen.getIteratorBinding("SearchView3Iterator");
  Line rw = iter.getCurrentRow ();
  
  oracle.jbo.domain.Date strDate = rw.getAttribute ("Tgl") (oracle.jbo.domain.Date);
  String strRkno = (String) rw.getAttribute ("Rkno");
  oracle.jbo.domain.Number strRkId = rw.getAttribute ("Rkid") (oracle.jbo.domain.Number);
  
  DCIteratorBinding iterParam = gen.getIteratorBinding ("variables");
  iterParam.getBindingContainer () .getVariableManager () .setVariableValue ("ExecuteWithParams_pRkId", strRkId);
  iterParam.getBindingContainer () .getVariableManager () .setVariableValue ("ExecuteWithParams_pTgl", strDate);
  iterParam.getBindingContainer () .getVariableManager () .setVariableValue ("ExecuteWithParams_pRkNo", strRkno);
  OperationBinding operationBinding = gen.getOperationBinding("ExecuteWithParams");
  Object result = operationBinding.execute ();
  }
  ***
  
  But when I tried the same thing on SelectionEvent, I did nothing... no error and also no results. What I want is just to select the line on the second table and get the result on the third Board, not any pressure from button. Here is the code:
  
  ***
  {} public void onRowSelect (SelectionEvent selectionEvent)
  DCIteratorBinding iter = gen.getIteratorBinding("SearchView3Iterator");
  Line rw = iter.getCurrentRow ();
  
  oracle.jbo.domain.Date strDate = rw.getAttribute ("Tgl") (oracle.jbo.domain.Date);
  String strRkno = (String) rw.getAttribute ("Rkno");
  oracle.jbo.domain.Number strRkId = rw.getAttribute ("Rkid") (oracle.jbo.domain.Number);
  
  DCIteratorBinding iterParam = gen.getIteratorBinding ("variables");
  iterParam.getBindingContainer () .getVariableManager () .setVariableValue ("ExecuteWithParams_pRkId", strRkId);
  iterParam.getBindingContainer () .getVariableManager () .setVariableValue ("ExecuteWithParams_pTgl", strDate);
  iterParam.getBindingContainer () .getVariableManager () .setVariableValue ("ExecuteWithParams_pRkNo", strRkno);
  OperationBinding operationBinding = gen.getOperationBinding("ExecuteWithParams");
  Object result = operationBinding.execute ();
  }
  ***
  
  Then. What is really going on here? What is the differece between ActionEvent and SelectionEvent? Why did give me answer of difference?
  Thanks for your comments.
  
  
  Kind regards

• No more ElementRange in SelectionEvent?

  To keep on top of the night builds to make sure I don't slip too far behind, and I made the relevant changes when it comes to EditManager

  noFocusSelectionFormat-> unfocusedSelectionFormat

  focusSelectionFormat-> focusedSelectionFormat

  selectAll()-> setSelection (0, editManager.absoluteEnd?) (not sure about this one)

  But that stopped me was SelectionEvent content is no longer a reference to an ElementRange I used strongly through the TLF "DOM", the first paragraph to lastParagraph.

  I came back to a previous Gumbo nightly, so no problem at all, but I was wondering if there was info on the upcoming changes regarding this last point (get an ElementRange from a selection)?

  Use the selectionState SelectionEvent property and call ElementRange.createElementRange.

  Hope that helps

• MacBook Pro display problem

  Hello members of the community.

  As of recently, I have noticed some glitches when feeding on my MacBook or awakened from his sleep.

  The colors are distorted, usually with pink, green, or yellow blobs. Blobs cannot entirely replace the colors, they appear to be contained in a element would normally be. For example. the menu bar will be partially pink and white, but pink does not leave the menu bar in this area, and the Office has green lines on it.

  I tried to take a screenshot, but the problem resolves in about 20 seconds, but it's a recurring problem.

  It happens when I wake up, connection or not. I had also certain powers serious and problems of performance, such that my MagSafe LED would not illuminate when plugged on rare occasions, fan could turn unnecessarily, graphics performance were SUPER slow, and the health of my battery was running out quickly. I actually ran a report on the system at 2 different times and my quality of full load is depleting of 1.2% per charge cycle, which is very worrying. I went from 6281 mAh mAh 6138 maximum capacity after two cycles of load. I'm tracking closely it because at this rate, my battery will survive only at load cycles about 150 instead of the 1000 expected, gives me the idea that this could very well be a bad battery. The computer is also warm to the touch while you sleep, not connected to the power supply. I NAP active but even taking into account should not be hotter my iPhone did the same thing.

  I have reset the SMC, and it solved a couple of problems. The charger works fine now and my performance improved considerably (which made me feel better, either it is a high-performance laptop, a 11-inch MacBook Air should not he surpass), and battery life has improved. I feel even if it uses a lot of power in his sleep. Maybe I need to turn off the NAP and see if that makes a difference. The graphic bug still persists however, and I don't have enough time to see if the max battery is depleting again.

  In regards to the bug, is there something that can be done? Basically, I want to assure you that I took all appropriate measures or if someone else has this problem to see if it can be software related instead of my computer.

  I have the entry level MacBook Pro with the retina, last generation.

  Any constructive contribution welcome!

  See you soon.

• with IOS 10.0.2 - 5s iphone Bluetooth problems

  Since upgrading ISO 10.0.2 my M50 from PLT Plantronics (helmet unique headset) do not reliably connects with my iPhone 5 more. I have to go to the settings, activate bluetooth turned off/turned on, touch the device on the bluetooth page, etc. Once it connects successfully, it will reconnect (if I turn off the headset and turn it back on) for a short period. The next day he does not connect itself but I play with bluetooth on the iPhone again.

  It has always worked perfectly before the 10th of IOS.

  And, as I noticed others mentioning, the volume is much lower with IOS 10. The maximum volume is much lower. I can barely hear it now, more normal background noise, while driving.

  I did:

  Forget this device for the PLT M50 and paired again (several times)

  I did a Reset Network Settings

  I don't know what else to do - but it's a 10.0.2 IOS issue.

  Hello AppleUser2k,

  Please ask questions about your problems of connection between your iPhone and your Plantronics headset since you upgraded to iOS 10. I understand how important it is to have your Bluetooth devices connect with your iPhone with reliability. Here's what I recommend.

  The first thing we want to make sure is that all your data is safe. You can perform a backup in iCloud or iTunes using this article: backing up your iPhone, iPad, and iPod touch.

  Once your data is safe, try the troubleshooting steps in this article to help: get help to connect a Bluetooth accessory with your iPhone, iPad or iPod touch device should also check with the manufacturer that the device has all the drivers and firmware to work with the new version of iOS.

  If you have checked everything and that you have installed the latest firmware or driver and always are problems, please be aware of your surroundings when you encounter these problems. If you can isolate the time or location, you see the problems, you can isolate the cause. You can even see this help article to ensure that you are not affected by outside interference: the potential sources of Wi-Fi and Bluetooth.

  Thanks again and have a great rest of your day.

• Problem activation ISO 10 September 2016

  After my Ipad iOS 10.0.2 update I could not activate because it says I am not access with the original Apple journal. Makes no sense. I bought the new Ipad in seven of 2013 Dabs.com. She has been linked to my Apple account 10 days ago (I deleted my profile by own Apple support Web site suggestion as a way to fix my problem, the other restoration/upgrade to the Ipad with ITunes update). I contacted the support of Apple (I have two numbers in case Apple). Asked Apple support to provide a proof of purchase I made. Told me now the reception that I provided does not correspond to my Ipad, but Apple isn't going to help with all the details to help to regularize the situation. The Ipad is mine and well was linked to my account from the date of purchase in September of 2013 until I removed it at the suggestion of site specific help from Apple. I now do not have access to my ipad £460 for more than 10 days and have lost money and time talking to 4 different cooperatives of Apple, after 6 calls and none seem able to deal with a ridiculous situation. Alexandre Vitorino (Apple) seems to have the best handle on weird how this situation is. Please can someone fix this? A software update on an Ipad that I own shouldn't stop me using it and then force me to prove that I admit actually before I use it again! I'm a professional businessman who uses it for meetings of the Council. I have a receipt for my camera and get treated like a kind of criminal.

  My sincere sympathy for those who can't find their original receipt or forget their original log-in Ipad because Apple does not help, you and your Ipad will be also useless mine is currently!

  If you are in the same situation please confirm to this post. I can't be alone, if she feels like it!

  Lock activation occurs when the ID of original Apple blocking it does not match with your current Apple ID.

  Until you can bring a receipt valid from an Apple reseller or authorized, it's nothing you can do.

  BTW, the polling stations in this Apple-owned forums is prohibited. You can review the terms of use.

  Anyone know how to solve my problem? I can't import my photos from Iphone to computer. Sign says: Photos in the camera cannot be imported because the IPhone is locked with a password or read. My phone is unlocked. I tried everything, every single idea. Without success! Any other idea?

  For example, you specify that the device does not display the lock screen, correct? Do you use Touch IDS? If so, try to put your finger on the device to see if it's what he wants.
