Ask about tables in adf

Hello
I'm new to ADF. Last day I was experimenting with tables of the ADF. I created an entity and a display object. I also created an application module. I wrote a custom method in the application module that returns all the rows from a view. Then, I created a JSF page and I dragged a table reading and created a button by dragging the custom method of the data control on the page. But every time the page loads, before I even hit my button, data are displayed in the table automatically. I want to display the data in the table, only after that the button is touched. Is this possible in oracle ADF 11 g?

Thanks in advance

Hello

oracle.jbo.server.ViewObjectImpl has a method "executeEmptyRowSet" ("method executeEmptyRowSet() performs the logical equivalent of execution of your view with a like predicate object' WHERE 1 = 2" (always false) in a more effective manner").

You create the view object class for your view object and expose the executeEmptyRowSet as customer interface. And if you use a taskflow, for example, you can use this method as being the default activity (drag and drop).

VO-class:

public class TestVOImpl extends ViewObjectImpl {
    /**
     * This is the default constructor (do not remove).
     */
    public TestVOImpl() {
    }

    @Override
    public void executeEmptyRowSet() {
        super.executeEmptyRowSet();
    }
}

Best regards

Martin

  • Ask about the filterable tag in the tables in the ADF

    Hi all

    We have a problem with the implicit filtering functionality provided by ADF. We followed all the rules of filtering:

    1 blockable = 'true' and sortable = "true".

    2 headertext is present

    3 filterModel = "#{bindings." InstanceDetailsVO11Query.queryDescriptor}.

    queryListener = ' #{bindings. " InstanceDetailsVO11Query.processQuery}.

    Now the filter works well. But after that reset us the page field filter still has the previous data entered by the user.

    Is there a way we can update the field as well?

    Any suggestions would be very helpfull1

    Thank you.

  • Ask about the creation and filling I$ table on different condition

    Hello
    I have a question about the creation and filling I$ table on a different condition. In which condition the I$ table creation? And these conditions are given below:

    (1) * source and transit area * are on the same server (that is to say target is located on another server)
    (2) * gathering and target area * are on the same server (IE source is on another server)
    (3) * source, transit area and target * are * different 3 * Server
    Source 4), area transit and target are on the same server
    Thank you

    I'm not quite clear to your question. Always try my best to erase it.

    In your all over requirement I$ table will be created.
    If the same staging as target (a database, a user) then all temporary tables are created in this user
    If the scaffolding is different from the target (a database, two users (A, B)), then all temporary tables will be created under that user A (lets consider) and the data will be inserted into the target table that is present to user B

    Staging is different from the target (two database, two users (A1, A2), architecture not recommended) if all temporary tables will be created under that user A1 (A1 of the databases) and the data will be inserted into the target table which is present in user A2 (A2 data base)

    If the source, staging, the target will be under a database then no. LKM is required, IKM is sufficient to load the data into the target. Especially for this, you can see an example given by Craig.

  • Ask about the use of MAPEXCLUDE and the table of wildcards in REPLICAT

    Hello
    Would give advice on this

    I got a REPLICATE that is roughly configured as follows

    MAPEXCLUDE TARGET_SCHEMA. TABLE1:
    MAPEXCLUDE TARGET_SCHEMA. TABLE2
    MAPEXCLUDE TARGET_SCHEMA. TABLE 3
    MAPEXCLUDE TARGET_SCHEMA. TABLE 4

    CARD PINPAP. ------*, TARGET TARGET_SCHEMA. \ * ;

    However, the behavior I see in newspapers indicates
    only the wildcard is including the tables that have been expressly excluded in the MAPEXCLUDE

    This is the behavior expected of wildcards? or have I misunderstood how wildcards should be used?

    Published by: Tensai2000 on April 20, 2011 16:42

    You don't want to filter the source tables? MAPEXCLUDE should be on the tables of PINPAP, not the target tables.

  • Ask about bind variables and LOVs

    Hello
    I'm new to ADF. Last day, I learned about LOVS, see criteria and bind variables. Now, I tried to develop a sample application. I created a few EOs, village and an AM.
    I also defined a view criteria which takes as a parameter a variable binding and rule the condition when running. Then, I created a group of query based on my view criteria. In this query Panel, when I enter the name of a student in a box (which is related to the binding variable that I guess), the student information is displayed in a table. Now, instead of an entry box, I want a list of choices based on a LOV-driven model that will contain all the names of students available. Is this possible in ADF 11 g?

    Thanks in advance

    You must open the VO, you use, go to the view whole section and in the view whole section go in the attributes section.

    In attributes, select the attribute by which you are to the search or make your operation, click on the button add to the list of values: the name of the attribute

    Select the vo object to fill the value.

    You will get the data in the variable binding, that you created in the view criteria.

    Reporter, you can follow the bolg

  • Ask about the feature find my phone

    Hello Apple support Team,

    I have a question about the find my iPhone feature which is as follows.

    -If I had put in place the "find my phone" feature when I bought the iPhone and did not open at all in 2-3 months. So that the disconnection of the app itself?

    I ask this because my phone got stolen yesterday and looking for opportunities that could have gone wrong.

    On my laptop, I'm always a corner of yesterday in front of https://www.icloud.com/#find to find the location, but its doesn't help not.

    (PS: this my second time that find my iPhone is not useful for me, I really wish that Apple must lock the turning the option off when the phone is in mode Code (lock mode))

    Waiting for your response.

    Thank you

    Ravi

    If you enable find my iPhone, it will be on except if you have disabled (requires your password to iCloud).  The location will only show if the phone is connected to a network and still has the power.

  • I have several questions about performance in XP that I asked about

    I have maybe something to do with my pc which has caused several issues that I have been asking questions on this site and have yet to get solved. Maybe it's a matter of slow internet access or an intermittent problem of internet access or a busy RAM which caused these problems for me:

    • 7 + 1 end Nows to Log Off or restart
    • IE cannot display the website (goes and load when I click Refresh!)
    • Enter the network password
    • Scrolling mouse (sometimes) when I click on a link in an e-mail or on a website or open a new tab opens to the blank page
    • Yahoo Messenger which is set to autostart in the Journal, sometimes impossible to display the weather plugin and so I just click on the v Options above and select Reset to Default height and it then displays to fill this place and it is currently running. What can I do to speed up my slow sometimes Tablet?
    • What can I do to speed up my slow sometimes Tablet?

    My Internet Explorer works fine, almost all the time and only question #2 or #4 occasionally and not very often. I need to put right at the front here saying that this isn't a malware problem and it is not a lack of program updates. If you could help me with this, just read my profile since these two are discussed in depth in my profile. I recently did a clean install and I visit unwanted websites on the internet and not much at all and I have installed Security Essentials immediately and it updates every day on its own. Also, I've updated all my programs and drivers manually and my operating system as much as possible by using Windows Update in custom update high priority mode (optional) software & hardware (optional). And I use File Hippo at each connection to find updates of programs that are available and I used another program to search for driver updates.

    I was unable to find information about malicious programs in your profile. Malware is STILL a possibility. ALWAYS. You run MBAM?

    Must you Yahoo Messenger runs at startup? (I doubt it). Plug-ins are also known to cause problems. If your plugin weather might be screwing things up.

    You have never set up a clean boot?

    Finally, you should never connect, I pointed out repeatedly. Reset must be a rare event, too.

  • Question about Table of Partition MBR

    I have a Toshiba laptop running Vista Home Premium SP2 with processor Dual-Core of AMD Athlon 64 X 2, 1 GB of ram and 150 GB of HARD drive.

    My question is about the partition table in MBR. It shows 4 partitions it.

    I have the Ultimate Boot CD, so I took a look at the MBR. Here are 4 partitions occupying its table:

    1. (without drive letter)-file system: blank - EISA config partition type code'n - 1.46 GB -: x 27
    2 C: - fs: ntfs - system, boot, primary, active partition - 92,01 GB - code: x 07
    3 D: - fs: ntfs - primary - 5.98 f - code: x 07
    4. (without drive letter)-fs: blank - primary - 5,64 GB - code: x 17

    c: is free of 17%, d: is 99% free, the other two are 100% free

    Can you explain what the purpose of D:? What about the other two (with no drive letter)? I read somewhere that ' x 17' code means "hidden IFS (ex: HPFS)' & 'x 27' means a rescue partition... true?". Do I need them, or I can remove the part'ns 3 (other than c :) & make use of space?

    Looks like the recovery and BIOS utilities. You need to check with Toshiba so one any of them can be deleted.

  • Ask about the Pause/break key on the keyboard

    As Saroseus,

    I have a program that uses the Pause/break to continue to operate and without it I can not continue to use it for work. The work of the society for us gave keyboards with the Pause/break key, but it is not ergonomic and it's hurting my wrist to use. That is why I bought this keyboard. This is a great keyboard and it works well, but I need this button "Pause". While Microsoft can do you something about it.

    Hello

    Let me ask you;

    • What exactly you're talking about when you say, ' I need this button "Pause"?
    • Is not the Pause/break key in the keyboard you purchased, working?
    • This keyboard does not have a Pause/break key?
    • Do you mean you bought now ergonomic keyboard?
    • The keyboard has Pause and break keys separately?

    It might be possible that some newer keyboards may have separate keys for the pause feature and the pause feature. Instead of these two functions are on the same key, the keyboard has a separate PAUSE button of the PAUSE button.

    On many keyboards, the key that controls the functions pause and break is usually labeled as the PAUSE button. As a result, many keyboard shortcuts show you "Press a PAUSE button." However, when you only press the BREAK key, the default behavior is to take a break.

    This behavior that many people know can cause some confusion on newer keyboards that have separate PAUSE and BREAK keys. For example, the newer laptops may have separate PAUSE and BREAK keys.

    Steps to reproduce the behavior

    Follow these steps on a keyboard that has one button PAUSE/ATTN:

    1. Open a command prompt window. To do this, click Start, click run, type cmd.exe, and then click OK.
    2. At the command prompt, type dir, press the ENTER key and immediately press the PAUSE/BREAK key.

      Note that the list of files in the directory stops. This behavior indicates that the default behavior of the key is to pause. To see this behavior for a directory that has a short list of files, you must press the PAUSE/BREAK key very quickly after you press the ENTER key.

    3. Press CTRL + PAUSE/BREAK.

      Note that the list of files in the directory stops and returns you to the command prompt. This shows that the secondary behavior of the key is to break.

    In addition, if you follow these same steps, and if you press the CTRL + Windows Logo + PAUSE/BREAK Keyboard shortcut to open the System Properties dialog box, the dialog box does not appear. This behavior is further proof that the default behavior of the PAUSE/BREAK key is to pause.

    If the keyboard does not pause button, you can use the screen keyboard and check.

    Open the on-screen keyboard by clicking the Start button , clicking all programs, Accessories, ease of access, and then click on-screen keyboard.

    You can see: using the keyboard (OSK) typing on-screen

    Hope this information is useful. Please feel free to answer in the case where you are facing in the future other problems with Windows.

  • Ask about webvpn error recovery

    Hi experts

    I have a query when webvpn error recovery is enabled, it won't save much in the ordinary crashinfo; However when it is disabled, it defintely records many details in the crashinfo .is this crashinfo for webvpn separately from the usual crashinfo or it is a part of it? I think that crashinfo webvpn can be seen by the command 'display details webvpn crashinfo '. Is this optional command to see the crashinfo (IE can be probably it will only give webvpn related information). The reason why I ask is that I can't understand if a separate crashinfo is saved in flash for the mistakes of webvpn if disabled error recovery?

    Well, the minidump is more information about the recover real webvpn. With accidents, normally we don't yet know the cause of root or what triggers it.

    As I mentioned earlier, if taken eventhough on error is enabled, if ASA itself could not get it back, it will still crash and produce crashinfo.

    Following your question, minidump and crashinfo are 2 different things. Minidump will provide information on recovery and crashinfo will provide a pointer to what specific function accident.

    Most of the customers don't like the ASA where it is actually at the scene of the accident. The webvpn error recovery function is to minimize the ASA to plant if possible.

    I don't think that allowing error recovery contributes to high CPU/memory usage. In fact, it is recommended to activate the function.
