• [ADF, JDev12.1.3] Mastering the form with detail tables: questions about Insertion/deletion, commit / rollback, primary key, handling,...

  Hallo,

  I have a panelTabbed with 4 tabs. In the 1st tab, there is a master form while each of the other tabs, there is a secondary table. Each tab "reads" vo.

  Please see here http://digilander.libero.it/flattit82/OTN_FILES/VoInTabs.png

  I created the graphichs/layout and now it's time to take care of the management of the transaction.

  In the master tab / form

  1)

  Here, I would put a button to remove the master record.

  When I delete a record in the primary table an automatism in the database (MS SQL Server) will automatically delete any registration which are linked to it in the detail tables.

  Could the automated system as this causes problems?

  In the Details tabs / tables

  2)

  I would put a button in each row to delete the line delivering. Can I just drag-and - drop, like button, af line: table the operation "Delete" of the VO istance detail used to create the af: table?

  3)

  If Yes, by clicking on the button performs the default delete operation. But if need to perform some actions before you run the deletion (or, in General, any other operation), how can I do?

  4)

  To create a folder that I use Create or CreateInsert? And what are the differences between them?

  5)

  When I create a new record I need set the value of a field of the VO on which is based the af: table. He filed, let's call it RowDetNumber, is not displayed in the af: table, because it doesn't have be filled in by the user. Mut value is calculated and set "secretly" before posting the new line to the database table. In particular, its value must be calculated as

  Select max (RowDetNumber) + 1

  of table_on_which_VO_is_based

  where some_conditions_on_fields_of_the_same_VO

  
  

  For example

  The VO selects all of the records that have FkId =: value. If value = 3, VO selection records:

  ID RowDetNumber OtherFields FkId

  1   3     1             ...

  2   3     2             ...

  3   3     3             ...

  4   3     4             ...

  The new record must be RowDetNumber = 5.

  I would like to know how permorm this.

  In general

  6)

  If the database tables have 1 or more triggers I have to take care of something?

  7)

  On the book "development of Web Applications with Oracle ADF Essentials - Sten E. Vesterli", I have read it could be problems when you use tables of database non-Oracle with auto-increment fields.

  The advice of author uncheck the 'Required' box in the model.

  All tables in my database have a primary keys that are auto-increment... so I uncheck the "mandatory"?

  8)

  In general how do I set these fields? I have to put in OT, VO or both?

  

  Thank you

  Hello

  (1) you will need to re - question child iterators so that they do not look stale data

  (2) Yes. Ensure that the table is PPRed after deleting the line (should happen automatically if ChangeEventPolicy on iterator is set to ppr)

  (3) double click on the button and it creates a bean managed for you. It allows you to check a box to generate the code he would run to remove the line. Everything you put in front of the generated code is your code before

  (4) in the case of tables, use createInsert as it adds the new line to the rowset (transaction)

  (5) suggest to do this use a database trigger and the data attribute value DBSequence VO type

  (6) do not 'drop table' issue in SQL (sorry, couldn't resist ;-))

  (7) If you follow the advice of the author, Yes. What it does, I have it does not throw an exception if a value is missing in the validation of the line

  (8) usually you set whatever it is at the level of the OS and put only things on VO if you want to override the default value for a specific behavior

• Create the form on table in the different schema

  Hi all

  in APEX I am logged in as long as user APEX_USER and the table, I'm trying to access the site with the creation on Table Wizard form belongs to the user. I have granted all privileges on a given user APEX_USER table, the wizard allows me to choose this table in the list, but when I press the next button, I get the following error message:

  You do not have access to the schema that you import. Import failed.

  Contact your administrator for the application.

  Seems to me that something similar had been already discussed here, but still no response.

  Please, what are the rights must have my APEX_USER to be able to create forms tables belonging to someone else?

  Thank you very much

  Pavel

  Edit: I did the same thing on my laptop (APEX 4.2.6.00.03) here and it works as expected. This error I get to work with APEX 4.2.3.00.08 (of course you should not necessarily be the cause, very likely, I don't have all of the necessary privileges) :-).

  Hi Mike,.

  Thanks again for your response. If the schema was not related to my workspace, I would yet be able to choose the other schema of the selection list.

  In fact, there seems to be a bug in the link in my message original (for example it is still not fixed in version 4.2.3), but fortunately I was able to find a workaround - I created a view with the same name and the same structure as the original table, and then I was able to generate the form with the wizard , finally I gave up the display and modification of processes page manually. So the solution is I have to force the DBA APEX upgraded to the current version :-).

• Created the form based on the table - created new line - how to retrieve line editing?

  Hello

  Sorry for such a stupid question, but being new in APEX, I don't know much about how the end user on a form.

  I have created a new form (not in a table), based on a table.

  I ran the form and created a new line.

  After the line was created, the form comes back ready to create another line (all the values in the fields).

  How can I go on the recovery of the line, I added just to make a few changes?

  Again, please forgive my ignorance.

  Hi landon39843319,

  You can have fields flowing / more dynamic in a PDF of LiveCycle Designer form, but not in an AcroForm (only created in Acrobat).  LiveCycle Designer is a program completely separated used for are delivered with each purchase Acrobat Acrobat XI has been release.  Now you must buy separately.  But LiveCycle Designer PDF forms are wrapped in a shell of PDF so that they will be displayed and can be filled in the free Acrobat Reader DC and earlier versions.

  If you do this in Acrobat with an AcroForm, you have as much information typed into a field that the user wants, but he's going to show everything on the screen.  Displays only the text that fits into the field, then a + sign will appear in the field to indicate that there is more text in this field, you can scroll down to read.  You can also set the automatic font size so that as more text is entered in the police becoming smaller and smaller to adjust the text, but that is usually not desirable for many forms.

  Hope this helps,

  Dimitri

  I created a form with fields default text for a user to update/customize.  Is there a way to style of the text, so I can quickly identify the changes to the default text in a field?

  You can use a validation script customized to each text field that looks like:

  event.target.textFont = event.value = event.target.defaultValue? font. HelvI: fonts. Helv;

  This will make the text italic (Helvetica) when the field value is the value default and regular otherwise. There are other properties that you can use instead, as the field color, border width, background color, text or text size...

• How to create a form on a table with 3 columns for a PK

  Hi all
  
  We have a table that has 3 columns that make up the primary key and I want to create a form based on this table; Let us on the 'create form Page' it is only 2 options that identifies the first and second columns of PK.
  
  Is there a way I could add the third column PK.
  
  Kind regards
  Mel

  Mel:

  I don't think you can use the form wizard to create the form for you in this case. You can create the form manually or modify the table to have a new column that will act as a substitute PK for the table. This column can be filled from a sequence and must have a Unique key limited defined against it.

  I think that you need a stored function (which returns the value) in this case, is not?

  Take a look at:

  If you have a copy of the original form, create a PDF file of the modified form and create a new PDF file with a different name that form original. It will be contained in the document layer with no layer form field or form fields. You can then open the original PDF form and use the "plug => replace pages...". "to replace the underlying content of the original form while maintaining the form field layer. You can now save the revised form. You may need to move the fields of the form due to changes in shape.

  How I changed the color of something? OK, so I use to be able to change the color of things, but now I have use color overlay, gradient overlay, or change the color when I first create the form, it turns into another shade of gray instead of change the color, I chose.

  Three things I can think of:

  Your document must be in RGB mode.

  Layer blending mode should be set to Normal

  Masks are grayscale. If you select the mask, you cannot apply a color.

  Always check your tab at the top to see if what you choose is RGB or grayscale.
