Back buttons and required fields...how to implement?

Hello
I would like some thoughts on the best approach to the following problem please.
-You have a wizard, lets say made up of 2 pages.
-Page 2 has some required fields.
-User goes from page 1 to page 2 then wants to return to page 1 for whatever reason.
-(Assuming they havent filled in the required components), what is the best way to let the user navigate back to page 1, without the system kicking in its required fields warnings etc..
One option I have thought of is populating the fields myself, but this feels like a hack.
Second option could be to edit the required=#{} of the required components when the back button is pressed?
Any thoughts?
JC.

Good tip.
ok, back to the main thread. immediate = true will result in any data the user entered being forgotten. The solution does by-pass the required rules, so its a mini result.
Tomahawk does have a stateSave component.
<t:saveState id="save" value="#{bean.xxx}" />
And a JavaScipt listener component.. I'm thinking both or one of these could be used to remember/store the state..
If anyone has any other solutions then please post.

Partial trigger and required field

We developed an ADF JSF application which some of field has partial trigger .
Then we add some required field.
when runtime when we change any partial trigger target item all field validated and "required field missing message" occurs.
How can we prevent this behaviour ?
why all field controlled against partial triggered items?
is it normal?
How can we solve this ?
Thanks.

Hi,
in JDeveloper 11 the implementation has changed and the issue wont be the same in most of the cases. There also is a notion of subform that allows you to only submit the field of interest - not affecting any other field.

I somehow deleted my "back" button in Safari. How do I get it back?

Two issues: 1st: I want to know how to take a snapshot of something on my desktop.
2nd: In trying to remember how to take a snapshot I was just pushing buttons, willy-nilly, and somehow deleted my "back" button in Safari. How do I get that back?

It's not on my keyboard (that I know of). It's an arrow on the bar at the top of my safari screen. I'm supposed to be able to click the arrow to either go back to the previous page or go forward to the next page. But I deleted it somehow. And now I don't know how to get it back. I found a solution in someone else's post: Safari, View, Customize Tool Bar. I tried to do that but it doesn't work for me. I dragged the back arrows to my tool bar but they won't stay up there. What do I do now?

Browser Back Button and form navigation

Some times when you use browser back button and adf-taskflow navigation buttons, validation on form fails, witout having made any change even with enabled token validation.
Reproduction steps on HR schema:
1. Create QueryDepartment and EditDepartment Views and navigation rules in adfc-config.xml
2 Create ADF view only table page for QueryDepartment selectable, and add navigation button to go to EditDepartment
3. Create EditDepartment form with navigation buttons and button to navigate back to QueryDepartment
test:
1.Run QueryDepartment and select a department
2.Go to Edit Department using navigation button
3.Navigate to next department pressing the 'Next' button
4.Navigate back using the Browser Back button.
5.Try to navigate back to QueryDepartment using the navigation button.
My result is validation error on DepartmentId field 'Error: JBO-25013: '
Is this a bug or am i doing something wrong?

Hi,
maybe I don't get it, but as I understood you have problem with focus on select button. So why don’t you set focus onLoad on another element of your page?
Something like onload=”$x(‘ELEMENT_NAME’).focus()”;

Somehow I messed up creating my hard cover book. I don't have the back cover and flap. How do I get it back?

somehow I messed up creating my hard cover book. I don't have the back cover and flap. How do I get it back?

What version of iPhoto are you running? Where are you seeing this lack of back cover and flap.
A first try fix is this: make a temporary, backup copy (if you don't already have a backup copy) of the library and try the following:
1 - delete the iPhoto preference file, com.apple.iPhoto.plist, that resides in your
User/Home()/Library/ Preferences folder.
2 - delete iPhoto's cache file, Cache.db, that is located in your
User/Home()/Library/Caches/com.apple.iPhoto folder.
Click to view full size
3 - launch iPhoto and try again.
NOTE: If you're moved your library from its default location in your Home/Pictures folder you will have to point iPhoto to its new location when you next open iPhoto by holding down the Option key when launching iPhoto. You'll also have to reset the iPhoto's various preferences.
If that doesn't help create a new book and see if the back cover and flap are in it. If so then it appears that your original book is damaged.
You can try rebuilding the library by launching iPhoto with the Option and Command keys held down and select the option to Repair the Database, option #3. If that fails rebuild again with option #4, Rebuild Database.
If that doesn't help then create a new book, verify that the back cover and flap is there and add the photos.

* In Firefox 3.6 versions on Windows and Firefox 4 on Windows and Linux it's possible to hide the "Menu Bar" via "View > Toolbars" or via the right-click context menu of a toolbar.
* Press F10 or press and hold the Alt key down to bring up the "Menu Bar" temporarily.
* Go to "View > Toolbars" or right-click the "Menu Bar" or press Alt+V T to select which toolbars to show or hide (click on an entry to toggle the state).

Created a form in Forms Central. Exported the PDF with Submit Button Option. When the PDF is filled out and submit clicked, it comes back asking for required fields to be filled but they already are. Any Help?

Hi;
OK - I can clarify some things and tell you how to do what your looking for.
The desktop FormsCentral application tools are really designed towards create forms that do collect data on FormsCentral servers. You can still easily create PDFs that do not submit data to FormsCentral, but you'll have to add any alternative submit functionality using the Forms tools in Acrobat. You can create a PDF without the submit button in either case, signed in/out of the Desktop Application from the "File" - "Save as PDF Form" menu item. You can then modify the PDF in Acrobat XI Pro by doing a "Save A Copy", when you open the copy you can edit it any way you like, adding a "Submit" button that email's the PDF/Responses back to you...
Here's how: In Acrobat open the PDF you saved from the FormsCentral Desktop application and go to "File" - "Save a Copy" and choose a location, this will remove the security. Open up the copy you just created and you can now edit it, here is a YouTube video tutorial using Acrobat XI, he covers the email button in about two minutes, there are lots of tutorials out there but this one is easy to follow:,

How to use one pop up window for multiple buttons and input fields?

Hi Experts,
I have created a pop up window that will be opened from multiple buttons in the same view. There are input fields that the data will be populated from a pop up window. How can I set up which button that a pop up window is opened from? I also would like to populate the data from a pop up window to the input field next to a clicked button. There are 6 buttons and 6 input fields that share the same pop up window. I would very appreciate your responses.
Thank you,
Don

Hi,
Try creating 2 context attributes, one in your component controller and the other in the pop-up view. Bind the attribute of pop-up view to the component controller attribute.
In the main view, on click of every button set a unique code in the controller's context which helps you in identifying the button clicked. Since u have created a binding to the pop-up view attribute the value flows from the controller.
In the init method of your pop-up view, check the value of the attribute and based on that display which ever UI elements are required.
Eg:
On Button 1 click set value "B1", Button 2 value "B2" etc. In the init() of pop-up view u can check the values and perform the required operation:
if(("B1").wdContext().currentContextElement().getButtonIdentifier()){
else...{
Hope this helps you.

I hate the update of the bar. It has totally done away with being able to skip back several places in the browser; now I can only click the back button and go back one page at a time. I otherwise hate the new layout, too. How do I undo this?

I can't choose a specific page to skip back to but must click the back button over and over to get back to where I want to skip to. The little headings "most visited," "getting started," "Youtube," etc. have changed. They look more colorful, but I hate how the home button is clear over to the right side of the page, etc. What was wrong with the way everything was before? I HATE this new update, and I didn't even want it.

You can get the drop down list by either right-clicking on the back/forward buttons, or holding down the left button until the list appears.
If you want the drop-down arrow you can add it with the Back/forward dropmarker add-on - https://addons.mozilla.org/firefox/addon/backforward-dropmarker

Back button and menu button don't work after spilling beer on it. How do I fix this?

A few months ago on a night out beer was spilt on my iPod, I let it dry out and it still worked fine.
However a couple of weeks later my back button started to play up, only working some of the time I pressed it, and then stopped working all together.
My menu buttong has also recently started to play up, with me having to press it and hold it down for it to work, and this only working some of the time. Any ideas on how this can be fixed? Or even how do I send it off to be fixed? My iPod is still within its one year warranty.
Thanks in advance.

How To: Disable the Print button until Required Fields are filled out

I have a PDF Form that I have created using LiveCycle Designer 8. On my PDF Form, I have a bunch of fields that are required. Is it possible to disable the Printer button until the user fills out all the required fields? We don't want a user being able to print out an incompleted form.

It's not possible.
However, you can create buttons on your document that "help" the user print
just a part of the document: a certain page range, just the current page,
etc.
