possible to customize #{bindings. Delete.Enabled} check at the ADFBC level?

11g ADF Faces w/ADFBC

It is possible to customize the controls for a deletion lie at the underlying level EntityImpl or ViewRowImpl?

On my page, I have a table within a collection of panels. On the toolbar of the collection of panels, I have a button linked to a delete operation on the iterator that provides the data in the table.

I want the delete button should be disabled for certain lines, from various data controls. (In my case, check if the DB line is referenced elsewhere in the DB). Is there an EntityImpl method or ViewRowImpl I can substitute to perform this check?

(I know I can replace remove() to check and throw an exception, but it would happen once the user has pressed the button on the web page.)

(I also know that I can get the desired effect at work by creating a method on a bean of support to retrieve the selected row in the table and on the basis of my custom logic control on it. However, I was wondering if there was a better way to work with the ADFBC framework to achieve.)

Thank you for reading my question.

A way to do it would be to create a transient attribute in your VO, which returns true or false based on the question of whether the line can be deleted.
Then in your page have the property to disable the button depending on the value of this transitional attribute.

  • accidentally deleted datafile empty at the OS level and have no backup of it!

    Oracle 11G

    Hello
    After you create a new data file, it was accidentally deleted at the level of the OS (AIX).
    Because it was new there is no backup of it.
    Now, tablespace think there is 3 files of data in it, but one of them is missing.

    Is it possible to recreate an empty data file on-the-fly?
    He left me the value of offline data file, but it wouldn't let me do anything else.

    Now, my backups fail as he acknowledges:
    "the State of the database file is RECOVER"

    Any advice would be greatly appreciated

    No problem, recover a file that has never been backed up is a standard training exercise (at least, that's if are trained by me :)))
    Just do this:

    create datafile 'fully_qualified_file_name' as 'fully_qualified_file_name' ;
    recover datafile 'fully_qualified_file_name' ;
    alter database datafile 'fully_qualified_file_name' online;
    

    This create a new empty, based on the definition of the missing file and apply all do it again because it has been created. without loss of data.

    Thank you

    There is no because it is impossible to implement.

    for the sake of discussion say that could allow "audit schema level.

    Which must take place within the DB when a new object is created in this schema?

    How Oracle will remember that this new object must be audited & as well as the types of access?

  • Is it possible to delete all entries in the Eventvwr log?

    Separated from this thread.

    Is it possible to delete all entries in the Eventvwr log, so I can go back to that is the app is written in the Eventvwr log?

    By default, event viewer produced a considerable number of newspapers.

    The four elements of the menu in event viewer bar are file, Action, view and help.

    Clear a log only appears in the Action menu of drop-down menu if the cursor is placed in a newspaper that can be erased and a report in the list is not currently selected. So if it is placed on the option Windows logs clear a log is unavailable, while "subject of a report in a folder under five is not selected, the option clear a log is available."

    The three main Windows logs files are Application, security, and system. The default file for these logs size is 20, 480 KB, which is larger than necessary. A reasonable size is 2 048 KB. You can easily change the size immediately after clearing the log by using the scrollbar to the right of the maximum log size to change whatever size you choose. In the same time make sure that the box before overwriting is checked. All of your changes by clicking apply then OK. If you have not disabled the first newspaper the system prevents the selection of a maximum file size less than the size of the existing file.

    see that the app is written in the Eventvwr log?

    The system records the entries in the logs. The system monitors everything that happens. Individual applications do not write entries in the Event Viewer logs. It's the system that records the entries on startup applications, stop and crashing!

  • Is it possible to customize the right-click menu?

    I use FF4 RC2 and I wonder if it is possible to customize the context menu? In FF3 if you right click on a tab lists ' new tab '. Reload tab reload all tabs... "etc. but in FF4 if you right click on a tab lists only "Reload Tab | PIN as App Tab... "etc.

    I really really use the right click-> new tab in FF3 A LOT! It was a HUGE disappointment for me when I started using FF4. Is there anyway that I could add the button tab in the right click menu?

    Thanks in advance!

    Not that I know of. You can use file > new tab or Firefox > tab in addition to what I posted above.

    Maybe an extension like Tab Mix Plus can add this feature in the context menu of the Tab bar.

  • I have about 14 000 songs in my library, about 4 copies of each of them. Try to remove duplicates, but can only do one at a time. I spent many hours, check all the files I want to delete only to find out that I can't delete them both?

    I have about 14 000 songs in my iTunes library, but really there are only about a quarter as much because there are so many duplicates. I don't know how they got there in the first place, and try to remove them is infuriating! I have already spent several hours going by checking all the files I want to remove (thinking that I would delete then all files at once) - only to find out that I still have to delete them one at a time. There must be a better way! Help, please.

    If you don't know that you want to delete all checked the songs in your library:

    • Create a new smart playlist with the following rules:

      This will show then checked all the songs in your library.
    • Select all the items in this playlist (Ctrl-A)
    • Hold the SHIFT key and press DELETE - follow the prompts to remove songs from your library and (if necessary) your PC media files

    In case of problem, you must back up your library before you do just in case the results are not what you expect - see tips to the user of turingtest2 on your iTunes for Windows with SyncToy to backup library for a suitable and recommended method.

    There is no 'simple' way to reliably remove duplicates from a library, but see the intelligence in this threadon the use of a scripted for removal of duplicates (for example).

    Long-term, try and avoid adding anything in your iTunes library that already exists in it - that's how arise the duplicates (unlike an opinion apparently dispersed, iTunes not of is duplicate anything in normal operation).  I've seen several comments suggesting here a few users to correctly copy their library from an old computer to a new one and then add the content of its media files - guaranteed way to finish with a copy of database entries or media files.
