• How to get the selected tree node and its attributes

  I have a 'af:RichTree' on a page, which is linked to a support bean (session scope)
  
  Here is my selection Listener:
  
  {} public void groupTreeSelectionListener (SelectionEvent selectionEvent)
  RichTree tree = (RichTree) selectionEvent.getSource ();
  Model TreeModel (TreeModel) = tree.getValue (); / /--> this line causes a "pointer Exception zero."
  RowKeySet rowKeySet = selectionEvent.getAddedSet ();
  Key of the object = rowKeySet.iterator () .next ();
  }
  
  
  
  
  what I'll do is get the note selected and then get all the attributes of this node, perform other actions.
  
  
  Please advise,
  
  Thank you

• Value of the selected tree node

  Hello
  
  I'm new to Apex (4.1.1) and I'm having a small problem.
  I had 2 Pages. The frist one is composed of a treeregion and a "submit" button.
  The Second is a report.
  
  I want to create a workflow, the user selects a treenode shipment and presses. Then it will be redirected to the reportspage,
  that will show him a report according to the treenode that he selected on the first Page.
  
  Problem:
  I don't know how I can read the value of the selected treenode.
  
  I hope you can help me.
  
  Thank you

  Hi Frederic,.

  To get the value of the selected tree node, you can make use of the "selected Page element node' attribute on the attributes of the tree page. Just create an element of your page and set the "Page of selected node element" of this new item page. Then fill the point via the BINDING of your tree query parameter. For an example, take a look at the following: http://apex.oracle.com/pls/apex/f?p=36648:6, where I put my point page P6_SELECTED_NODE to the value of the node selected in the first tree that is empno. Your report query must refer to the node selected item "Page, to make sure it displays information about the selected tree node.

  I hope this helps.

  Kind regards

  Did you watch net.rim.device.api.system.USBPort?

  That's what the doc says:

  Provides access to the USB port of the device.

  Avoid using this class in applications, as it is not portable. On the contrary, if you need to access the USB port, use factory CLDC Connector to serve a connection.

  If you have VI Analyzer installed, you can load the configuration file and look at the section select the Tests. There is a test for the maximum size of front under front-> User Interface. The default value is the resolution of the current monitor of the PC (including multiple monitors). You can change to the desired option.

• Dual Boot with windows XP Pro with 2 HARD drive, error on secondary windows install: "Windows did not start because of a configuration of the disk of the computer problem. Could not read the selected boot disk. Check boot path and disk hardware... »

  Hi, I recently bought a new Hitachi 1 TB internal hard drive. I wanted to do a clean install on the new drive (d), be able to dual boot my computer and leave my old 300 GB disk (C :) as the primary windows installation. After physically installing the new HARD drive, I noticed that "new hardware found" and the the brand name flashed in the bottom right corner. I thought I'd see the new hard drive in my computer, but I did not. I initialized the new HARD drive with the computer management window (right click on my computer - manage) and I also formatted in NTFS (I had to change my printer hard drive letter to assign the new HARD drive with the letter D, but I've made other changes after this step). Now, I could see and use in my main windows on the C: installation. I then installed a windows new copy XP pro with the installation CD I got for my C: but on the D: (Note: I have a Dell computer (and the Dell reinstallation CD) and my current version of windows has SP3 while the installation CD is only SP2) (I also reformatted my HARD drive during the installation of windows to NTFS)

  Now when I try to start on installing the new on my D: I get "Windows did not start because of a configuration of the disk of the computer problem. Could not read the selected boot disk. Check startup disk and hardware access path. "and another line saying to refer to manuals HARD drive and windows.

  My Boot.ini file at this time was:

  [boot loader]
  Timeout = 5
  default = multi (0) disk (0) rdisk (0) partition (2) \WINDOWS
  [operating systems]
  "multi (0) disk (0) rdisk (0) partition (2) \WINDOWS="Microsoft Windows XP Professional "/ noexecute = optin/fastdetect
  "signature (ac516a5c) disk (0) rdisk (0) partition (1) \WINDOWS="Microsoft Windows XP Professional own "/ noexecute = optin/fastdetect

  I looked towards the top of this help page, but for now I'm unlucky:

  http://support.Microsoft.com/kb/314477

  (The next steps I took by throwing from the Windows CD and go into the repair console)

  I tried to use the bootcfg /rebuild but the line to boot.ini for my secondary HARD drive still does not work.

  He gave me something like:

  [boot loader]
  Timeout = 5
  default = multi (0) disk (0) rdisk (0) partition (2) \WINDOWS
  [operating systems]
  "multi (0) disk (0) rdisk (0) partition (2) \WINDOWS="Microsoft Windows XP Professional "/ noexecute = optin/fastdetect
  "signature (ac516a5c) disk (0) rdisk (1) partition (1) \WINDOWS="Microsoft Windows XP Professional own "/ noexecute = optin/fastdetect

  I also tried to change the signature() to multi (0), but it did not work. (or try almost all possible permutations of disk() and rdisk() partition() 0 to 2).

  I also tried to use expand F(dvd-drive):\i386\ntkrnlmp(I_have_a_duo-core).ex_ D:\windows\system32\ntoskrnl.exe and a few other combinations, but I when I login as D:\windows simply, it fails to extend with a message like "could not develop" or C:\windows I get "restricted access".

  I have not yet tried CHKDSK/r, but since I did a clean install on a newly formatted drive... I don't think it would work.

  I've also marked the partition on the D: as active (in computer management), but it did not help me.

  I've done a first installation of windows repair, strangely, I couldn't fix this one... Still does not work...

  My default windows installation yet works very well & I see that windows has been installed on the D: but I'm ideas from how to operate the dual-boot, can someone throw me a BONE on what to do?

  Maybe try to do something with the Boot Manager (whatever it is?) Create a new partition and use it as a boot manager? I don't really want to do this, because if I made a mistake I will be unable to use my computer and dual boot should work without going through all this trouble... But I found this page: http://technet.microsoft.com/fr-fr/library/ee829686%28WS.10%29.aspx

  Could a clean install two HDD help? I hope I won't have to do...

  Someone has an idea?

  PS: I'm not such an advanced user so I need a solution step by step, thanks!

  Edit: I also noted that I can't see my new HARD drive in my BIOS... weird... SATA-0 is my old drive HARD 1 and 2 are my dvd 3-5 readers are 'off' and it doesn't seem to be anything that it is plugged in. I also have 4 bays for internal HARD disks. Now, 2 are busy.

  Edit2: I looked inside my case and enabled the good Sata in the Bios after a reboot it detected the drive correctly. Dual boot doesn't always work well... The fact that it was disable in the BIOS while I was installing the new HARD drive could change anything? Hmm...

  In case I wasn't clear enough: I had a windows XP Pro installed on my C:, bought a new hard drive and installed the same copy of windows on it (d). I think that should allow me to double boot between the two installs different. Even if for some reason I can't boot from one on my D:. Andrew, I do not understand why you so far physically disconnect the other drive, the point of the whole operation is to build a boot.ini file so that the BIOS knows that it y facilities 2 windows and you allow to choose (and not have conflicting problems between the 2 systems), someone correct me if I'm wrong? "Expand" the part of my first post made reference to one of the solutions provided by Microsoft in the first link that I have included in my previous post (but I can't seem to work).

  In addition, it is the procedure that I followed: http://www.ehow.com/how_5950826_boot-two-different-hard-drives.html

  (except I've had the first installation already done).

  Andrew "also, once a new hd is plugged on the pc & running, most of the BIOS will place (them) as 1st priority hd, set the BIOS to do this", you mean that by installing separately from windows on each unit when the other is not plugged in, I could choose what disk to start from defining their priority in the BIOS once they are all plugged back? It's too tedious (as I intend to move frequently between the 2 installs) and requires a computer to other users of the lack of computer knowledge. Unfortunately, it is not a viable option.

  EDIT: I DID IT! Hmmm... Well, I double checked in the recovery console, the path of the new HARD drive with the arc command Scan. Tried to start again with the MULTI (0) in my boot.ini and it worked... I also had my windows install CD in. Maybe that is why I could not start, windows needs the CD to complete the installation? Weird, I don't know what I did to the difficulty it... but hey, it works! Thanks for your ideas guys!

  Any idea?
  

  Well, you can use selectionListener to set the selected line to a variable of bean (but this bean must be in extended view or some superiors)

• How to read the value of an independent textInput element inside the method?

  Hello
  
  I had a group of detail based on a readonly viewobject. I added an independent element textInput, you say, EndDate to this group that the user can enter a value inside. Now, when I run the app I select a row in the table and press a button that triggers a method inside a bean. My question is how I read the value in independent textInput (EndDate) within the method element?
  
  getTable () .getRowData () does not print the unbound attribute. It seems that it only contains attributes underlying viewobject
  
  I use JDev 11.1.1.4
  
  Kind regards
  Will do

  Will do,

  You can better create a transitional attribute for that in your view object, so you can use a regular expression #{row.bindings...} to get the value.

• DVT:pivotFilterBar - how to get the selected values of the filter

  Hi all
  
  I have a question: how to get the selected values from the pivot table filter bar programmatically?
  
  I tried to use

  pivotTable.getDataModel().getDataAccess().getValueQDR(startRow, startCol, DataAccess.QDR_WITH_PAGE);

  but to the edge of the side DATA INCORRECTESdeclarations page, it seems that it will return the cached values.
  
  Environment: JDev 11.1.1.3.0 without tasks.
  
  Thank you
  Miroslaw

  Hello

  You can retrieve the value selected in the PivotFilterBar through the PivotFilterBar model, instead of dataaccess:

  Download the template of the bar pivot filter instance
  QueryDescriptior queryDescriptor = (QueryDescriptor) pivotFilterBar.getValue ();

  retrieve a list of criterion, each of them is used to fill each lov in the pivot filter bar
  ConjunctionCriterion conjunctionCriterion = queryDescriptor.getConjunctionCriterion ();
  List criterionList = conjunctionCriterion.getCriterionList ();
  for (int i = 0; i)<_criterionList.size(); i++)="">
  AttributeCriterion = (AttributeCriterion) criterionList.get (i) criterion.

  _selected is the currently selected value
  Selected object = criterion.getValues () .get (0);

  System.out.println (_selected);
  }

  Hope that helps,

• How to read the status of User1 DIP-switch with a cRIO FPGA chassis?

  How to read the State of the DIP switches on a FPGA cRio chassis?

  I work with a cRIO 9022... My idea is to put the system in "service" mode with USER1 switch to IT and communicate with the FPGA via the FPGA - GUI (VI) on the host computer instead via the RT module that is used in normal conditions.

  Any ideas? Unfortunately, I don't have an unused channel on the left... .and (as I know) cannot use the interface RS232 of FPGA.

  Many thanks in advance,

  Luke

  Hi, this is the correct information. You cannot read the FPGA of DIP-switch status. The only thing you could do is to use the function of Reading Switch.vi located under the range of functions-> real-> utilities RT time

  It's how you probably know side host RT and not the FPGA.
