Switches and uses parameters in the fragments of the page

I spent the weekend trying to get information on the use and passing parameters into areas (page fragments) with little success.
I use JDev 11.1.1.3. with the merger of ADF for the project.

I got a train set that uses a jspx and is long of 5 elements (all fragments of the page).
I have a page of research as an entry point (page fragment). This contains the main table, the remaining elements (page fragments) in the train are children to the master.

I need to pass the primary key of the mastery of all the fragments and you also have to set the field in the table when records are inserted (it is a data control).

I found no examples - and the tutorial uses no - one Bean support for fragments or primary jspx who maintains the region.
Ideally, the bean of support would be in the jspx that contains the box (as would be, and the fragments are changed).

Also, as the primary key (foreign key in fragments) is never displayed - I'll have to update these keys the records are inserted (some are tables and forms).
I read on the triggers of context - and think that they could be used (inform the parent of selection and insert actions) and the parent may be able to capture and define these values.

I would have thought the DC would have been smart enough to understand the relationship - but alas - I get the error message saying that the foreign key is missing.
I suspect that the domain controller can be unique to each fragment (I updated the scope of Commons - but not sure that this will help).

Can someone give me a hand (I'm sure this has been done before) or point me to an example (tutorial), who can give me information.

Also, is there a way to put an exit point on the train (e.g. as terminus) If users can leave at any time (it is a train not sequential).

Page of the fragments in train stations that contain the details of the main line, that you select on the first page, wouldn't have new lines created on these fragments of page automatically linked to your selected master? Therefore no primary key would not even should be passed to fragments of the page because framework would make the link master / detail appropriate for you.
If this is not the case, have you tried using pageFlowScope variable to hold the values through fragments of page? If everything is in the same taskflow, then pageFlowScope variable would be ideal for this. Even if you agree on each train stop, values would be always kept there so you can use them again and again until the workflow ends.
Also, have you taken into account the built in 'CreateWithParameters' operation to set default values during the creation of new lines on the detail of the fragments of page? In this way, you could use passed parameters and set the values of your attributes without writing a single line of backup code bean :)

I hope this helps!

    My hotmail account has certainly was hacked and used to change the DNS settings on a vauable domain name registration.

    Hello raulganau, welcome.

    I suggest to try the system restore to restore the system to a date before the problem started. Try this...
    1. click on START
    2. click on "all programs".
    3. click on "Accessories".
    4. click on "system tools."
    5. click on "system restore."
    6 follow the instructions on the screen to restore the system to a date before the problem started
    Although the system restore does not target the personal data, I recommend always backup your personal data, just in case something happens.
    For reference, I have included a link that provides more specific information about the restoration of the system and how to use it:
    Let us know if it works,
    Thank you!

  • 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.

    The font size of header and footer is still low. Last time I looked, I couldn't find a way to replace the default size of 10 others to choose a font that is intrinsically superior to Times New Roman as your default serif font. See: can I possibly enlarge the headers and footers in the "Page layout" menu of Firefox to make bigger it so I can see it better... or is this something I won't have to deal with being so SMALL. I don't check for a complementary solution; You can try looking for one on the Addons site.

    As the position on the page, some printers don't allow you to get all the way at the edge of the sheet. If that's the problem, you might be able to fix in the General settings of your system for your printer dialog box. I don't see a way to access of the Mac print dialog (Firefox print dialog screenshots in this article: How to print webpages in Firefox), so that you may find in Control Panel.

    If this does not work, there are certain preferences that Firefox stores with names similar to the following. In these environments, 25 = 1/4 inch (the value is divided by 100).

    • Print.printer_BrandX.print_unwriteable_margin_top
    • Print.printer_BrandX.print_edge_top

    To modify these, you can use the subject: configuration preferences editor. In a new tab, type or paste Subject: config in the address bar and press ENTER. Click on the button promising to be careful. Then use some of the more unique terms (for example, unwrit or edge) to filter the list.

    Hi florent!

    I think that the problem might be that you use a bundle function to merge signals, which creates a cluster which you can't enter the Express VI for sounds. There are a few options that you can use, the first is to use a merger signals VI (im attaching a photo) then get the parameters and their entry into the chart. The other option would be to use low lvl functions that are on the table Palette, called table max. and Min.

    Hope this information helps you, let me know if there is anything else I can do for you.
