Hello! questions asked by a developer of new forms of Apex

Hi all!
I am a developer of forms since 1998 and I was looking at the apex since version 3.2
I am really impressed with version 4 and the next 4.1 news, so tonight I decided to go for it take a look at it!

My first question is about the design of data base:
It seems that apex encourages the design of pk id number and not another approach.
for example, I have a table user_group:
ug_group varchar2 (5) pk
ug_description varchar2 (50) not null

When I create a simple tabular form the pk is retrieved and then in the next step i wonder to 'Set the source for the primary and foreign key columns' Existing sequence etc...
So I created a custom pl/sql (return null) to go...
When I start my page I see only available for update or insert description field, what can I do with my pk varchar?
So, I wonder about my design? Should I need to rework my table and make the id of way? or is there another solution?

Another question (generally a matter of forms developer):
What enter and execute query functions? Is it possible to have the same, or is the standard way to have default search results?

Thanks for your attention
Concerning
Jean-Yves

Hello

Default Apex Hides the primary key column and assumes that it will be a numeric field used to create relations only and not for data entry. However if you want to manually enter the primary key you can display the column (which in fact instead of hidden text element).

So, I wonder about my design? Should I need to rework my table and make road id? or is there another solution?

It seems to be a better way to have a numeric ID field, but it is not a must.

What enter and execute query functions? Is it possible to have the same, or is the standard way to have default search results?

N ° it's different in the Apex and my humble opinion, it is much better than Enter/Execute Query. Whenever you create a form, you get option to create 'A form with the State', so it creates an interactive report with the data entry form. For example, you can search for interactive report and edit link allows you to change the recording.

Just for you information in a table and not much in the Apex as other (non-tabular) forms are powerful. People including Oracle Forms really want because they make better.

    Just have a link on a page, e.g.:

    And then tap on it

    If you are directly connected to the server, simply create a folder (what looks like) Z:\ToExport\RepDocs\ which is the new name of Fortin, ex:
    Z:\ToExport\RepDocs\NEW_folder and put the files into it. If you are now directly connected to the server, use a program such as FTP server to connect via FTP and do the same thing.

    in other words:

    It is simply because http://myserver/Myreport/ is set to point to the Z:\ToExport\RepDocs\MyReport file so it looks http://myserver is set on the Z:\ToExport\RepDocs\ folder anything you add to a folder which will be included.

  • ADF Mobile: question of iOS app development

    I know that I can deploy the same application to iOS by creating a profile of deployment. However, I'm a little confused on this from the tutorials.

    So the question is can I develop a Mobile application in the ADF on a windows machine and keep the test on an android device and once satisfied enough to create a deployment profile, and deploy on iOS?

    What could be the possible problems?

    how it is important to test on a real iOS device during development?

    Also emulator iOS runs on the windows machine that I see in the tutorial to install xCode and Mac.

    Hello

    What could be the possible problems?

    the deployment on iOS requires iOS SDK and an example of Apple Developer for the signature. That being said, you need a MAC to create a deployment for iOS.

    how it is important to test on a real iOS device during development?

    As with browsers and big ADF: in theory, everything works the same and the framework takes care of possible platform differences. In practice, especially if you run a business, you want to QA test the application on all platforms, you want to take in charge your request. In the best case, you do not find a problem and everything works as expected. However, if for some reason, there is a difference, you would be happy to have run the test

    Hi all

    Table in which I have summarized your concerns has been assigned to the Backr room as well. If it is OK to continue the discussion here, you can do this by using the Backroom as well because it gets more visibility than what you post here.

    As I understand it, the Forums team works with Jive for the biggest of the first road.  Given that we are less than a week, with the new interface, I suggest that we have waited some time for patches.

  • How to open a new form on button click in form 10g

    Hello

    Can you please how to open a new form, when you press a button in the form of 10g.


    When I was in Forms 6i, this was done through OPEN_FORM('forms_1',ACTIVATE,NO_SESSION,SHARE_LIBRARY_DATA);

    But this code is not set 10g.

    I am developing through Citrix remote server where I am facing this problem. In the local PC no problem.

    Help, please.

    Hello

    Make sure that D:\myfolder\ is defined in the FORMS_PATH environment variable. FORMS_PATH is defined in the default.env(ORACLE_HOME/forms/server register) or windows. If it is set in the two default.env is a priority.

  • Change 'new form submission' text on receipt of e-mail of the contact form.

    Hello

    One of our clients asked us to change the text that they receive when they receive an email from the contact form.

    It currently says: "new form submission.

    they want to tell him: ' West of the Moon ~ Ayr ~ site survey '


    We tried to change the name of the form, but does not change the object in the email, not the text in the email. Is it possible to do this?

    Hi Richard,

    Please check the php script to which the web form submits to that open with a text editor and change the verbiage you want here.

    PS - You will need to make these changes after each export of Muse as Muse will override them on each export/download.

  • PREFORM VS VS A TIME NEW FORM INSTANCE QUERY PRE... That you choose?

    PREFORM VS PRE-REQUETE:

    What will be exactly preform will fire? In a screenplay where the user enter a field as entry, based on this child on the same form will block gets its data... If, in this scenario IS PRE FORM IS SOLUTION FEASIBLE?... can we do where manipulations of the article here...

    PreQuery:

    where do cluase manipulation here. and loop on... I heard that loop in unauthorized prior request and we cannot use next record kind of stuff.


    PREFORM VS WHEN the NEW INSTANCE of the FORM, which is the better place to put the code for deformity overiding dynmically run query based on the values of some queryable form field...

    Thank you
    Prasanth

    PREFORM fires once at the start of forms before you navigate to the first item/block.
    A TIME-NEW-FORM-INSTANCE trigger once after the PREFORM before you navigate to the first item/block.
    QUESTION them fires each time before any request on a block. It is the right place to manipulate the default where the runtime.

  • New forms for R12.1

    Hi you

    EBS R12.1
    OEL 5.4

    I'm confused with the new forms launched used in EBS R12.1 :(
    It differs from the EBS R12.0.4 when you launch it. And of course far from 11i
    What do you call this form now? Is - this gui form? Web form? HTML form? form of Java? etc.
    There same executable .fmx in $APPL_TOP? I can open it with the form 10g developers?

    Our consultant said it serves to 11i and now does MD50 for custom report and give to this
    for developer reports to make the program. Her problem is that she cannot identify the columns and
    tables associated with the form, so she comes to give us the "navigation" to the forms to see the columns online.
    She also said that in 11i, she just use ' row who? for the columns and tables associated with shapes.

    The part very hard, which makes custom in EBS reports is how to get the tables behind forms, because most of the time you get a 'view' with the misleading values and columns.

    My question is, what is the counterpart of this 'line that' in 11i for EBS R12.1?
    Or how you map columns to the forms at the tables?

    In your experience how your consultants functional make a MD50? She is the one to identify the
    the tables and columns? or it is the responsibility of the developer.

    It is also true that Oracle Support does "not support" customized reports errors?

  • How to make a new form in the Mainmenu submenu options?

    Hi you all form gurus.

    I desperately need your help.  Because I did receive one of the answers to my question, just thought to move the original title for the content below and edited the title and we hope to get more attention to my request for help:

    Why a new form in the submenu of the Mainmenu options is grey out?

    I added a new form as one of the options in a submenu in the Mainmenu.mmb.  But the new form is gray in the submenu.  The new form has been compiled OK without any errors, and I was able to create an executable file.  After addition of the new form of the form of application security, but the new form is always grayed out (not accessible). What seems to be a problem here!  (It's probably a very simple/simple problem of these gurus of forms there.)  BTW, we are always in forms 6i w / Oracle 10.2.

    Thanks in advance for any help.

    Hi all

    Finally, I thought about it and share the solution with you all.  I changed the article "Enabled" section in the palette property of the new item in the menu of the 'NO' to 'Yes' and because of this my new accessible form (i.e. it is is more gray in the submenu option.)  The thing that made me for awhile was enabled is set to 'NO' for all other submenu items and my way of thinking, that's why the new form must be different from the rest of the elements.  Lessons learned here is never assume anything until you try it.

    See you soon!

  • New forms from scratch: preferred form design program?

    I know that Adobe products specialize in Microsoft or HTML documents to PDF conversion.


    But what about new forms from scratch?  You use drag and drop builders of form made by third parties or do you use Adobe products?  What is your favorite for the construction of simple forms of the two columns layout?  Please be specific.  Curious to see what products you use to design new forms.
