Troubles when trying to transfer a table with hierarchical column to a tree

In WD for ABAP, I encounter many troubles when trying to transfer a table with hierarchical column to an actual tree. In my UI, the tree is in the left pane and the detail for a node is in the right.
1. With hierarchical table, I can bind the dataSource of the table directly to the context node in View which is mapped to a context node in component controller which is a DDIC structure. But with a tree, is it possible to map the dataSource of the tree or node in tree to context node in component controller?
2. With hierarchical table, when lead selection changed, the detail info in the right pane will change automatically. But with a tree, it seems to have to be implemented via action by myself.
Can anyone give some suggestions to overcome these troubles?

Wei,
<i>With tree table, the dataSource of the table is just bound to the context node ORG_UNIT</i>
Hmmm... You said, that this node resides in component controller, not in view controller. Or does it?
Any recursive node that can be displayed with tree table can be displayed with tree as well. Period.
1. Create tree and bind data source to the same node as table data source.
2. Create tree node type and bind it to the same node again.
3. Create one additional calculated attribute in forementioned node (type boolean) that inverts/negates attribute for table column "hasChildren" to tree node "isLeaf".
4. That's all.

  • How do I fix the "Expected handle" error when trying to transfer a file with FireFTP?

    I'm trying to upload a ZIP file to my FTP folder with Blackbaud and cannot do so. I've entered all the parameters exactly as instructed by Blackbaud and all connections look good but when I go to transfer the file, I get the following message: "Expected handle: /users/B67E610BAA01/"H:\Downloads\BUMFS RE7 Database.zip" "BUMFS RE7 Database.zip"." All I can do is click "OK" and nothing happens other than seeing a repeated loop in the log that alternates between "noop" and "ok."

    Make sure your account has the proper permissions to write to the location. I ran into this exact same problem, and that was my solution, anyway...

    Cryptic message!
    I saw a definition online for this that said:
    Cause:     An integer value in an internal Oracle structure overflowed when being sent or received over a heterogeneous connection. This can happen when an invalid buffer length or too great a row count is specified. It usually indicates a bug in the user application.
    Action:     Check parameters to Oracle calls. If the problem recurs, reduce all integer parameters, column values not included, to less than 32767.
    Which seems even more cryptic.
    Then checking on another forum with this error, I saw:
    Q. I am getting the above error trying to run a free hand SQL report on two tables that are materialised views (database links) on our reporting database from our production database. Now the bizarre thing with this is that the report does not work on my computer or our production server, however one of my team mates can run the report.
    Can anybody explain why this error might occur? I am able to run free hand SQL on any other table. The Oracle error talks about a CLOB, but if that were the case, why would it work on a different machine?
    A1. Check if you have the same version Oracle client on the three machines. What happens if you run the query through a different tool like TOAD or SQL*Plus ?
    Final A. The problem was due to the different versions of Oracle Client. I was running 9.2 on my PC, I had 9.2 on the server and it wouldn't work. My collegues were running 9.0.1 and had no issues, once I changed back to this version on both my PC and the Server, the problem was gone.
    I think the problem was something to do with BO 6.5.1 as the report was developed in 6.1.a and worked fine, as soon as we upgraded the porblem occured.
    If you are not using CLOB's, I would suggest going down the track of checking your Oracle ver.
    So, with all that info, I'd check:
    1. are you using Disco Desktop and getting this?
    2. Materialized views?
    3. Links to another database in your folder?
    4. Do you have a different Oracle client that others? Can others run the same report and all okay?
    5. Can you run the same query in TOAD, SQL*Nav, SQL*Dev, etc?

    I get an error saying that selected videos will not play on the iPhone. They were purchased from iTunes and have been played on the phone previously.
    So far I've only noticed it on SD/HD videos, but not all SD/HD videos. Not had an issue yet with the judt SD files.

    Hope you are having a lovely afternoon today! I'm about ready to go bobo....I have an early meeting, and I don't want to oversleep! The nice part is that I work remotely, so I only have to wake up 15 minutes or so before the meeting.... I don't even use an alarm clock anymore (really, my iPhone alarm, which is much more pleasant), unless I have to get up at 6:30 or something....

  • Itunes crashes when trying to transfer music

    I have been having problems with my new 160gb ipod classic and transferring songs from itunes. I have had no problems with it verifying the ipod. When I try to transfer songs it will just crash for no reason and blue screen my computer. I've just updated my computer to Windows 7 and installed itunes 9.2, my previous Windows Vista was using 9.0 and I had no problems. Is anyone else having crashing issues when trying to transfer songs? The only way I have been able to get my songs onto the Ipod is doing it 2-3 songs at a time and even then it will still crash eventually. This is taking forever to import my cds onto my boyfriends new Ipod. I have yet to try my own Ipod classic to see if that has problems as well.

    Did You try downgrading iTunes to older version ? I can see that others have had problems with new version of iTunes. If that fails, try to select playlists in iTunes to sync one by one ( manually of course ).

  • Itunes closes when trying to transfer purchases from ipod or iphone

    Using a PC with Vista.  Installed iOS 5 this morning.  Cannot update either ipod touch 3g or iphone 3g with software update until "prior purchases are transferred to itune" - unfortunately every time I try to "transfer the prior purchases" Itunes closes completely.  I've been working on this for hours now.  Anyone got any ideas how to get around this?
    Thanks.

    Your Post is a bit confusing

    If you are using iTunes, you cant transfer purchases in the iPod to the Mac, you need 3rd Party Software.

  • When comparing database tables with lob columns via "Database diff" in different environments indexes are shown as different

    When using "Database diff" selecting other schemas only for compare own objects are shown too!Hi!
    For tables with lob columns (clob, blob, etc.) indexes with system names are automatically created per lob column.
    If I am on different database instances (eg. dev/test) these system names can differ and are shown as differences, but these is a false positive.
    Unfortunately there is now way to influence the index names.
    Any chance to fix this in sql developer?
    Best regards
    Torsten

    Only the Sql Dev team can respond to that question.
    Such indexes should ONLY be created by Oracle and should NOT be part of any DDL that you, the user, maintains outside the database since they will be created by Oracle when the table is created and will be named at that time.
    It is up to the Sql Dev team to decide whether to deal with that issue and how to deal with it.

    When trying to set up syn with outlook 2010 - outlook it does not show as an option

    Hi smrkevin,
    Welcome to the BlackBerry Support Community.
    What version of BlackBerry Desktop Software do you have installed? If you do not have the latest version listed here: http://bbry.lv/ds97JW I would advise upgrading it.
    If you already have the latest version of Desktop Software, can you verify if you are running a Click to Run installation of Outlook? You can check this in Outlook -> Help -> About Microsoft Outlook. If you are using a Click to Run installation, you will need to install a full version of Microsoft Outlook to setup synchronization. For more information, see: http://bbry.lv/qDIoXO
    Hope this helps.

  • Error when attempting to merge into table with RLS - ORA - 28132

    hey,
    i've encountered an "ORA-28132 - Merge into syntax does not support security policies" when attempting to merge into a table with RLS defined on it.
    i looked around and found this [discussion |http://asktom.oracle.com/pls/asktom/f?p=100:11:0::::P11_QUESTION_ID:259415261270] on ask tom.
    according to the thread - this was a bug in 9i. in 10g merge is possible only if the policy returns "null" and in 11g it was finally fixed.
    *i have been able to merge into tables with rls in 10gR2 in some cases.*
    i would like to know if anyone has some more information about this error. when can i merge into tables with RLS ?
    thanks, Haki.

    Never.
    The bug was that it did work sometimes in 10g i.e. it should always raise an error.
    It's something that I've always found a bit odd and frustrating - that MERGE and RLS policy should not be compatible.
    But bottom line is that you shouldn't be using MERGE on table with RLS policy.
