[SOLVED] Create ViewObject as placeholder for the parameters of the form

Hello

I posted the following question (JDeveloper 11.1.2.3):

http://StackOverflow.com/questions/14592202/create-ViewObject-as-placeholder-for-form-parameters

Basically, how do you create a ViewObject that can perform validation and harness LOVs, but don't don't don't need to be supported by any source of data?

Is it still the right approach?

Thank you!

Hey, Timo.

This can be accomplished without an OA. As far as I can tell, it's the right answer, but this forum does not allow me to choose my own answer as correct, but somehow allows me to report my own post as an abuse. Strange.

# Solution

You have:

-Create a view object to be programmatic, with the desired attributes.
-Configure the view with validation rules object.
-Configure the Module of the Application.
-Create the form on the web page.
-Update the page link to create a new line.

# Create object View

Create the view as follows:

1. type Control+n to open the * New Gallery *.
1. search and select * view object *.
1. click on * OK *.
1 set * Package *, * name *, and * display name * properly.
1 set * data * to * programme *.
1. click on * following *.
1. click on * new * and provide a significant attribute name.
1. click on * OK *.
1. Add the remaining attributes.
1. click on * following *.
1 set * Updatable * to * always * all attributes.
1 set * Type * for the appropriate data type.
1. click on * finish *.

# Configure Validation rules

Configure the following validation rules:

1. click on the * attributes * tab.
1. Select the desired attribute.
1. click on the * tab Validation rules *.
1. click on the * + * icon in the * section Validation rules *.
1 set it * rule definition * as required.
1. set * error * as required.
1 Repeat to add validation as necessary rules.

At this point a view object has been configured and the * list tab of values * can be used to reference LOVs based on a query.

# Configuration Application Module

Configure the module of the application as follows:

1 double-click on the module of the app.
1. Select * model data * tab.
1 Shuttle the object view of * available see items * to * model data *.
1. remove the * 1 * suffix.
1. save the application.

Note: If the view object is not visible, restart JDeveloper.

# Create Web Form Page

Create a web page to the form as follows:

1. create a new JSF of the object view page.
1 update the * data controls * see the instance of the view object.
1. drag and drop the view on the page object.
"1. Select * form" ADF form *.
1 check * include submit button *.
1. click on * OK *.

The web page is created.

# Update the Page link

Cannot change the attributes of the view object unless there is a 'line' created for the instance of the view object. Creation of this line in memory must occur before the display of the content on the page. Accomplish this as follows:

1 extend the data controls to reveal the view object * operations *.
1 drag * Create * in the facet of footer.
1. Select * ADF button *.
1. right-click on the page.
1. Select * go to Page definition *.
1. click on * + * next * executable *.
1. Select * invokeAction *.
1. click on * OK *.
1. set * id * to: create
1. set * lie * for: create
1. click on OK.
1. the refresh value: * prepareModel *.
1. save all.

You can now remove the create"" button.

The validation is applied, and data-driven LOVs can be used.

    Hi Nancy,.

    Encryption of files and folders is a way to protect against unauthorized access. EFS (ENCRYPTING File System) is a Windows feature that you can use to store information on your hard disk in an encrypted format. Encryption is the best protection that Windows provides to help you keep your information secure.

    You can make a folder and then encrypt it.

  • How can I get rid of text "Is a placeholder for the content in the topic" production HTML5 MS?

    With the help of RH11.03 - Multiscreen Layouts of HTML5 (don't know if it applies to provision adapted).

    Whenever I generate help, the "' next placeholder text appears at the bottom of the theme files:

    Enter the Desktop '(default) topic' file shows this placeholder text, I can delete to let the empty paragraph tags. However, whenever I have save/generate the file, the text is displayed again (and so there are several paragraphs of placeholder).

    How can I remove this text. I have opened the Layout.CSS file and see the following for the "contenttopic" div class and the wTopic widget, but I have no idea how it generates the placeholder text:

    You could do all of the light would be appreciated.

    Thank you

    George

    Let the widget.xml in the State. If you change this one, your output may break!

    If you open Topic.slp, remove the '

    This is a placeholder for the content in the topic.

    '. The editor of RoboHelp adds text to placeholder alone.

    You can also use the HTML HR display to remove this code. If you close the Topic.slp WITHOUT going first in design, HR should not add the code.

  • create a default value for the file types

    I created a new site and is a kind of ColdFusion document.

    Dreamweaver creates ever new htm file when I right click on the folder of the site to create a new file for the site.

    I wonder what's possible to leave Dreamweaver to set the default file type.

    For example, Dreamweaver can create cfm for ColdFusion site files and php for PHP site.

    Your information and help is much appreciated,

    Kind regards

    Iccsi,

    I don't know what version of DW, you have, but in CS6 preferences panel allows you to specify the default document type and file extension for all new files that you create in DW.   This does not affect your existing website files.  Only for new.

    To edit existing documents, go to modify > Page Properties > title/encoding.

    Now, if you are working on several sites with the requirements of the other script, you can specify the type of page to create by clicking file > New > blank page > choose a page type.

    This help you?

  • Oracle HRMS (EBS R12.1.3) - placeholder for the rooms/labs and meeting phone numbers

    I'm looking for a placeholder in the human resources base to store meeting rooms / laboratories / details (name, number of phone & extensions) of the training room.

    I am using the screen of the organisation (Structures of work-> organization-> Description). Here we define the classification of the Organization as "Training Center", I only get a field to store telephone numbers. I know that we can have the phone number attached to the structure of localization work.

    As we have many laboratories and rooms meeting/training in the same place, I don't think this is a good option to create multiple sites for the sake of phone numbers.

    We have sown flexfield descriptive "Org Developer DF" used to define the Types of information organization. As a seedling, I'm not touch to activate the additional fields.

    Could someone please advice what should be the best approach I should follow to add the meeting rooms / laboratories / HR Core training room details. Please let me know if I'm not clear or need additional details.

    Thanks for your help in advance!

    Could define a location Extra Info structure (multiple lines)? Any org would then one place for his main address, but which could in turn have several entries in location additional Info to save details etc at this point in the meeting room.

  • File extensions do not created when saving images for the web, using the slice, Photoshop CS4-slice tool

    Working with slices in Photoshop

    When I save slices through "Except for web devices", in PS, the resulting images are file extensions but appear to be image files.  I can open in Windows Gallery Viewer and see them however, they have no icon other than a blank page icon, not the usual png or jpg types.

    To solve this problem I added manually .png and .jpg those pristine images through their file names. It seems to work very well for the resolution of jpg files.  In addition, when registering via 'Save for web devices' slices I chose manually imput to the second field and following: PNG or jpg.  This results in the names of files with .jpg but not .png [both png12 and png24]

    When you save slices:

    1. choose the file type

    2 save

    3. internal record Panel: choose:

    (a) image only

    (b) Selected slices [or user slices - as seem to have similar results]

    (c) in the settings: other:

    (i) disable: copy the background image and create the image folder

    (II) for the file nameing use: slice of name and in the second field, add the file extension: jpg or png.

    PNG FILES

    I seem to have problems to import any .png file, created from slices via 'Save for web devices' method, in PS and Fireworks.  However, I do not seem to be able to import them into Illustrator and Indd.

    I want to do is to be able to create slices PNG and JPG files and follow the method "Save via web devices" without having to become an expert in all the options in the Save Panel.  And then be able to import it into Fireworks or in PS.

    Is there something in the preferences that needs to address, or there at - it a bug of sumfink?

    To solve the problem of file extention:

    1. When you save file slots in the Panel 'Save for web devices' and 'Save' Panel appears. Then, you click on 'other' in the settings and do appear the file naming options panel.  Make sure you keep ".ext" in the substantive area of naming options.

    Yes, that's the error.  Now file for .png extensions are created and therefore work OK in Fireworks and Psalm
