What does the Create action not?

Hello

I use JDeveloper 10.1.3.4 and you have questions about the action Create {color} {color: blue}.

I have a data table named USERS and a corresponding VO in the data control palette. Drag and drop the original Version of users to the page as a table with the column of enabled selection, I let the user be able both to delete a selected line and create a new line.

I'm new to this, but for deletion, there is no problem: drag the delete action under the control of data users VO and drop it into the table {color: green} > table facets > Selection > af:tableSelectOne - Select and node {color}, then drop the request module commit an act on the page also as a commandButton control. And the selected line can be deleted and committed deletion using these two new buttons.

Similarly, I dragged the action Create {color} {color: blue} and he fell in the table {color: green} > table facets > footer node {color} like a command button. When the page is running, nothing is visibly when you click on the button create {color} of {color: blue}. I understand that you do not select a line to create a new line, so I did not put the button create in the same node with the button Delete. And I guess I'll have to create a separate page for the user to enter the values in the fields on the line must be created.

What I want to know, what's this button with the action {color: blue} create {color} inside is different than a generic commandButton created from the ADF Faces Core > commandButton? If I create a commandButton control in the component palette that is empty inside. But by using the action of creation as a commandButton control, is not yet clear to me that creating would make the action inside the key. On the other hand, there must be a reason for the {color: blue} action Create {color} be there slot that VO in the range of control data for us to use. What is the reason? And that makes the action Create {color} {color: Blue}?

Thanks for answering my question!

Hello Newman,

If you want your new line to be available in the whole of current lines (for example to edit directly in the table, not on a form), then take a look on the CreateInsert operation. Otherwise, you need a form to edit the new line.

Check out these links:

What I want to know is how this button with the create action that it is different than a generic commandButton created from the ADF Faces Core > commandButton?

When you create a button for the create action, your page links are configured automatically, then a link to action to create a to-do from the iterator is added to your pageDef (and this iterator is bound to your view object).

And what is the Create action not?

The create action creates a new line but does not insert it in the whole of lines.

Kind regards
Patrik

  • When you use find on the page (ctrl + F on Windows) it is a message indicating the total number of matches. What does the first number?

    When you use find on the page (ctrl + F on Windows) it is a message indicating the total number of matches. What does the first number?
    I'm more interested in the case when this number is smaller than the total.

    Hello

    I think you mean the text stating "x of there matches", to the right of the box where you entered the search term.

    The first number ("x" in my example above) indicates the current entry highlighted on the page that matches the search phrase. If you use the upper and down arrows to navigate through the instances of this term on the page, you will see this number go up and down.

    I hope this helps, but if not please come back here and we can look at another solution for you.

  • What does the "AUTO" in PARALLEL (self)?

    What does the "AUTO" in PARALLEL (self)?  I know what is the PARALLEL indicator.  Usually, you either would not include something in parentheses after the suspicion or would you include a number in order to establish the statement of principles.  What happens when you use AUTO instead of a number for the declaration of principles?  I can't find an online article that explains this.

    Thank you.

    What does the green dot on my desktop icons?

    Hi Jamie

    The green dots are probably coming in a third-party program.

    Some backup programs, such as Carbonite, will overlap at a point of color icons of file or program to show the status of backup of this element. In addition, some abtivirus programs will use these points of overlay icon.

    Most of the programs will be an option to turn off the icons.

    I hope this helps.
