How to manage the directory structure (disclosed keys) if nodes are added/removed?

Hi all

I use Jdev 11.1.2.2.

My use case is that we have a structure (tree created by programming) as:
Fruits[0]
->Grapes[0,0]
   ->Seeded[0, 0, 0]
      ->Black[0, 0, 0, 0]
      ->Green[0, 0, 0, 1]
         ->Riped[0, 0, 0, 1, 0]
         ->Unriped[0, 0, 0, 1, 1]
   ->Seedless[0, 0, 1]
      ->Black[0, 0, 1, 0]
Note: The numbers inside "[]" indicates the key (disclosedRowKey) of the line of the node.

If I'm deleting the node "Seeded" then the line of the node key "Seedless" should become [0, 0, 0] and respectively for its child node.

But in my application when I delete the "Seeded" node, the keys to total communication is not get altered so that it is looking for the old lines and when he is not able to find what is throw no exception available line.

* Is there a method to change the disclosedRowKeys of the tree?

For the moment, so not only no available line exception, we are the disclosedRowKeys of compensation and adding key to line all of the node to the disclosedRowKeys.

It's a little embarrassing when the tree is large, because it expands all nodes, whenever the new/delete/open operation is called.

It will be helpful if you can give me a solution for this and let me know if you want more details on my use case.

Thank you
Vignesh.

Far as I can tell it is a function not implemented and proposed workaround.

    If you haven't done so already, take a look at the action of com.vmware.libarary.soap.processOutParameters.  It is the action that generated the log you have placed in us.  It generates an object Properties (key, value pairs) with the value for each setting that results.

    In your case, assuming that 'outProps' is the result of the above, you can use:

    var getRequestStatusResult = outProps.get ("GetRequestStatusResult");

    And to analyze the code XML with E4X as Ilian said.

  • Change the Directory Structure created in the MPZIP file

    I'm trying to normalize my projects of Multisim for inclusion in our documentation control system. As I build my project, I have a directory structure that I use. When I include the files in the project, the directory structure is known in the MPZIP file. However, the default value is decompress all the files in the external folder (name of the project). Suite to help,

    Hi Doug,.

    When you unpack the project, the default is to create a new folder and put it all together because it is unlikely that the new computer will have the same file structure as the computer on which this project of.  If you want Multisim to create the same structure as the original file, you can click in the cell under "excerpt from path" and select the old path, if the folder does not exist, Multisim will create a.  Unfortunately, you will need to do this for each item on the table.

  • How to manage the photos Lightroom when using 2 computers, keeping any changes made on one or the other?

    Based on http://forums.Adobe.com/thread/1308132?TSTART=0 I decided to add each question separately:

    Hello, I am very interested in buying Lightroom 5.2. I tried the RC that was missing today. Yet, I have several questions that I can't find really good conclusive answers, I'd like to get an answer before buying LR. Please do not write maybe like this or that (assumptions), because I don't want to start my entire workflow and then realize that I have to change all around, please reply, if you know for sure that something works and you are, preferably, using this method too.

    Is the big question, where I want to especially a conclusive answer:  How to manage the photos Lightroom when using 2 computers, keeping all the changes made on one of them, using the same photos for editing. I'm not going to use DNG. Details: I mainly use my old MacBook Pro, but I wish I could use my PC as it is much better (card: i5 2500K, 16 GB of RAM, SSD, USB3, nVidia GTX 560 TI etc.). I have 2 external HD that I could use, one for backup and one for the actual Photos/changes. I you will probably need to use as my internal HDs are fairly complete and I cannot be the kind of things simply delete or move to one (developer, without loss of music, programs etc.).

    On this basis, how do I save all such Photos folder (pictures and retouching and preferably presets too)?

    According to me, that it should be possible to work cross-platform without having to create a link to the files each time, or without having to keep export/import of the catalog, keeping the single catalog and the picture library on an external drive that is then switched between systems as needed.

    Obvious first requirement is an external drive that is formatted in a way (for example, FAT32) that it can be used on both platforms in read/write mode. Given that, if the catalogue AND folder parent si le catalogue ET le dossier parent images are both set to the same level in a global parent folder, then it should be possible to take advatage of ability of Lightroom to use relative paths instead of absolute paths to detect the images, no matter if the player is named (Mac) or lettering (PC). This is how "export as catalog of ' works, that is, it creates a 'package', alias a parent folder, containing the catalog and a replica of the folder hierarchy to exported along with the catalog images. Take this 'package' to another system (same OS or not) and "it works" even if the drive letter is different or the operating system is different... because the relative path of the image catalogue is always the same.

    I have not tested this cross-platform (if I have between various PC systems with letters of different readers) so for me it's still just a theory, but there may be others who have done this successfully.

    In addition, the following file locations is not found because they no longer exist. So why the backup wizard continues to look for and how to remove the backup set? I guess the error code following each line means simply that records cannot be found. Is this correct?

  • How to manage the hierarchy in the list of key words

    I have a few keywords that are nested two levels down, but when I click on and drag on the key word to move it to the top one or two levels in the hierarchy, it does not move. He's here. Of course, I know how to put a key word in a lower hierarchy but now I need to move some of them to a higher level, as you can do it in the Navigation pane on the left. Is there a place outside (LR) where I can go and manage the hierarchy?

    Suppose you have two keywords, A > B > X and has > X and you want to merge all the A > B > X pics has > X and delete > B > X.  To do this:

    1. in the keyword list Panel, hover over A > B > X and click the arrow that appears to the right of the keywodr.  This will exactly show photos that have A > B > X.

    2 Select all these photos by Edit > select all.

    3. in the Keywording Panel, in "Click here to add keywords", type "has > X»  Now all the photos that had a > B > X will also have A > X.

    4. in the keyword list Panel, right-click A > B > X and select Remove.

  • What is how best to manage the product in use keys?

    Hello

    BizSpark partner

    My questions are below.  These questions were raised because I wanted to install the software for which product keys have been provided, but I realized that I wasn't sure of key that had been previously used.  I thought I would just look at the product installed for his key. After an online search, it seems that is not possible and I think I understand why, but I'd like confirmation of my understanding or correction my understanding if I don't have it right.

    Therefore, I have 2 questions (attention he received questions for each question):

    (1) are the product keys not available for viewing on the computer where the software is installed?  Is - it to protect against software piracy?

    (2) what is the best way to manage the installation of the software to ensure that we remain within the limits of our license?  Do we not have manual records every time we install a software application?  Or y at - it a program that can be used to collect and total software in use with its product keys?

    I posted this under Windows 8, but I also have Windows 7 machines in use.

    Thank you.

    Hello

    Thank you! All the best. Be careful in choosing to shared storage.

    # If your shared file system accessible via CIFS, SMB or Samba, you may search and/or performance indexing and corruption problems when you use the Verity search engine (not supported in 11g).

    # If your file system shared accessible via CIFS, SMB or Samba, you should disable opportunistic locking (oplocks - data client-side caching) of the file system as it might interfere with the normal operations of Content Server. With solutions for storage network (SIN), the performance of the file system may be closely related to oplocking (data caching client-side), which disables the opportunistic locking can cause performance problems. Please plan your architecture accordingly.

    Please feel free to correct if you get your answer to other purposes.
