• Is this a bug? HTML is not escaped in the conditional read only LOV page elements

  Then test my application for injection HTML filling HTML for each column in my data injected datamodel HTML running when a field only LOV ready, I noticed
  
  
  
  I have dynamic LOV in use in my form, so their share, users can select. That sometimes I don't want to make them able to change a value, they chose earlier.
  
  For this reason I condtionalu readonly my LOV. by using the conditional read only an option for the items on the page.
  
  
  
  That's when a dynamic LOV made readonly HTML code inside is done instead of escaped
  
  
  
  is this a bug or is it intentional?

  Geert - Thanks for the info. I think that's not a bug. With the read-only option, it displays the data as it would for a display text (does not save the State) items for which source of HTML element, that is, unescaped. If you want the text escaped by using your dynamic lov query simply use htf.escape_sc:

  Select htf.escape_sc ('data') d, 1 r of the double

• Restricting the views to DISPLAY ONLY the rows CreatedBy current connected user

  I want to user Oracle views - restrict the view to DISPLAY ONLY the rows CreatedBy / current OwnedBy signed / authenticated user!
  
  What are the different approaches, I have something with;
  setNamedWhereClauseParam, but this must be called on each ManagedBean in the constructor, as I have now!
  This approach caused the button Edit/Save which simply calls the commit to stop working. In a complete view of all the lines, there is no problem, with
  the button requesting validation the selectedRow in af: table.
  
  Other means?
  
  Thank you

  It does not appear that your view object extends the framework with custom code extension class in dealing with populating the bind variable by default.

  You get it because dims_t is an array of OBJECTS - not a table of scalars. But your SELECT statement returns scalar.

  There IS NO such object, named "dimension_id"; It is an ATTRIBUTE of the object DIM_O. DIMENSION_ID is a SCALAR which, as says the exception, is a "No nested table element; If you cannot select/Update lines of it.

  What you do is equivalent to the following:

  DECLARE

  dims_t dim_T;

  number of dim_id;

  dim_o design;

  BEGIN

  Design: = dim_o (3, 'ghi');

  SELECT DIM_O (DIM_ID, LABEL) BULK COLLECT INTO table DIMS_T (d_o);

  end;

  PL/SQL: ORA-22905: cannot access the rows of a table not nested element

  ORA-06550: line 7, column 1:

  PL/SQL: SQL statement ignored

  This SELECTION is trying to design it as a table when it's a SCALAR - so the same exception you get.

• Implement conditional read-only column in the set of two Tables

  Hello
  
  I would like to implement a mechanism of "read-only conditional" on a column in a table with two tables in total to be involved in this situation.
  
  I have a demo/proof of concept of the present and things work as expected in the tests I've done; However, I would like any input as to if there is a better way, etc.
  
  This is a far-fetched but demo that illustrates the main ingredients however. Oracle 10.2.0.4 version 64 bit on Windows Server 2008 Release 2 64-bit.
  
  -Table DDL and small sample data
  

  create table band(
    band_id   number primary key,
    band_name varchar2(20),
    status    varchar2(20)
  );
  
  create table band_member(
    band_id references band,
    member_name varchar2(20)
  );
  
  insert into band values(3, 'The Rutles', 'prefab4');
  insert into band values(4, 'The Beatles', 'established');
  commit;
  
  insert into band_member values(3, 'Ron Nasty');
  insert into band_member values(3, 'Dirk McQuickly');
  insert into band_member values(3, 'Stig O''Hara');

  insert into band_member values(4, 'Paul McCartney');
  insert into band_member values(4, 'George Harrison');
  insert into band_member values(4, 'Ringo Starr');
  commit;

  -The rules relating to the conditional objective of read-only
  
  1 is not allowed to update band.band_name when band.status = 'prefab4'
  2 is not allowed to insert/update / deletion of lines of band_member when the parent a band.status row = 'prefab4'
  
  -The triggers used to implement the goal (current solution)
  

  create or replace trigger t1

  for each row
  when (old.status = 'prefab4' or new.status = 'prefab4')

    raise_application_error(-20010,

    select status from band

  -Quick example of test for each condition

  As I said, while my simple tests seem to show the correct results, there I was wondering if there could be a better way to implement such functionality.

  I'm went to the road to slider to add the clause "for update" to force the serialization on the line - i.e. the idea was to avoid the case where another session might want to update the State a moment after my extraction but before the rest of the finished code. Who is?

  No, not really. The trigger on tape prevents anyone else from ever change their status from 'prefab4' to something else (or vice versa).
  Even apart from this, you put some efforts to prevent something which will be allowed a fraction of a second later (or maybe the other way around). What is significant in that split second?

  I didn't think about other ideas rather than the approach of the trigger, but came up empty, somehow, to this day. I am open to resort to others and make some schema changes is not off the table either.

  FGA (Fine grain access), or his brothers and sisters more older VPD (virtual private database) can also do what you want, but instead of trigger an error, they ignore the illegal action. This can be an advantage or a disadvantage, depending on your needs.

  Another approach is for the owner of the table, not to grant INSERT, UPDATE or DELETE privileges to anyone: all DML must be made via a procedure (or procedures) belonging to the owner of the table, which grants EXECUTE privileges instead of other privileges.

• Get all the rows of a table control

  Hi all

  I have a table with a column control. What function can I use to extract all lines? I have to go row by row and read each line or is it possible to do in a function?

  Thank you

  Kanu

  Assuming that Garay in the column have all of the same data type, you can retrieve the entire column with a single statement:

  GetTableCellRangeVals (Panel, control, VAL_TABLE_COLUMN_RANGE (1), array, VAL_COLUMN_MAJOR);

  The array passed must be large enough to recover all data. Alternatively, you can replace the VAL_TABLE_COLUMN_RANGE with the appropriate statement of MakeRect macro. In the event that your table was built of dynamically, you can get the naked, imber of lines using GetNumTableRows and size your table accordingly.

  The above macro is defined in userint.h as well as some other useful macros that can be used to access the data in a table.

  There are a few precautions to be taken in the case of string values or a certain type of cell (ring, combo box, button...) that are described in the hell of the function.

• Read only the terms - master detail

  I have a page with a master detail

  I created a read only condition and the master passed to read-only, but the detail does not...

  Why? Is not possible to put the retail component 'read only '?

  Hello

  If I understand, you want to the form is editable when the user is an admin user

  and read only when the user is a normal user.

  You can solve this problem by the use of dynamic actions

  to enable and disable some elements of this region (s)

  make this condition (standard user = admin = enable and disable)

  Another solution

  When do the master / detail with the wizard choose change details on a different page

  On the link change, you can set a condition (visible only when the user is ADMIN)

  Kind regards

• Read only the SPI using the box USB-8451

  I am using the NI USB-8451 box to read the SPI of a Honeywell digital pressure transducer data.  The difficulty comes from that part of Honeywell uses only the SPI in half-duplex mode, meaning that it only transmits data, but does not require anything beyond the appropriate chip select signal and SCLK to start transmitting its 32-bit sensor data.  To facilitate experimentation with the sensor, I bought a USB-8451 SPI Interface thinking I could easily configure the 8451 to read data from the sensor.

  However, if I understand the situation, there is a problem.  The 8451 considers full duplex data, i.e. a data word must first be sent to the SPI device in question before the unit will start to transmit back data of its own.  And since the MOSI data writing periods, since this particular device starts transmitting immediately once a clock is applied, synchronizing the unused address data will cause the unit will return its data before the 8451 begins listening for data in return.  The call used by the 8451 to write read action can be divided into the individual reading and actions of writing of any kind that I could discover.

  Can someone tell me if I missed something in this operation or if there is some quick tips, that I could use to be able to use the 8451 therefor?  Thank you!

  Doug G.

  Exactly correct. It's nice when things are easier than expected. Hope it works as easy as it sounds.

• Read only the af:inputText rendered as "merged" instead of read only entry

  I use JDeveloper 11.1.1.6.0
  
  I noticed that when you use components such as "af:inputText" and "af:inputDate" with the attribute "readOnly" set to true, rendering resulting is a label as a "< span >" as opposed to a read only < input > element which I expected. I see the behavior expected if I use the component 'h:inputText' of JSF with "readOnly" set to true, however, I can't use the JSF component because it is not as if I can get the 'autoSubmit' behavior to work with the JSF component then it will not work. To add to the strangeness of the behavior, if the af: inputText has its lines attribute, the value is greater than 1, it will be rendered as a read-only < input > element as opposed to a label.
  
  In addition, default readOnly to the af form: inputText seems obvious when using the simple skin or other skin based on simple. It adds a box which surrounds the exact length of the text in the inputText rather than the amount of space the inputText would have used if it wasn't in "read only" mode.
  
  Is it possible to get the af correctly: inputText to make as a reading introduced only as opposed to the label that he is displayed as?
  
  Thank you.

  Hello

  It's a decision taken by the rendering of the component. If it is a problem for you and if you have a support contract client then you can file a service request for a change.

• Read only the virtual disk?

  Hello-

  I have Vmware Server 2 x86_64 installed on my Hardy Heron Ubuntu 8.04.2 Server x86_64 and it seems to work very well.  I have created a virtual machine for Slackware 12.2 and put the DVD iso, Slackware in the right directory.  The virtual machine starts the DVD fine and I started the Slackware Setup.  However, when I went to set up the hard drive with cfdisk (part of the standard installation process Slackware) I noticed two things:

  1. the drive has been turned ReadOnly, so that I could not score; and

  2. I created a virtual disk of 11 GB, but in cfdisk he only appear only 4.7 GB.

  What I am doing wrong?  Any help would be greatly appreciated.

  Thanks in advance.

  Well, I'm just guessing because I haven't worked on the software you're talking--can be the partition its display corresponds to the DVD player itself as the DVD is normally read-only and the size of the disc is 4.7 GB. .. You can check it out please.
