Help with simple display and add in ADF/Struts app

I created a simple ADF/Struts application based on the HR schema. I have a department view object and entity object based on the Departments table. From the Struts page flow designer, I create a data page action (viewDepartments) that binded to a departments view object by dragging the departments view object as a "Read-Only" form from the palette with the navigation buttons --- this page will just display the departments. Next, I created another data page action (addDepartments) that allows a user to add a department. I did this by dragging the departments view object from the palette as an "Input Form" and then dragging the "Create" operation onto the data page action. Each data page action has its own JSP of course.
I'm noticing that every time when I go to to the "addDepartments.do" and then go to "viewDepartments.do", a blank record is added to the view object. Why is this? Also, I want the Submit button to do the "save and commit" in one step. How do I do that?
If it helps, I can email anybody the workspace file so that you can see this behavior.
Thanks.

Try following this step by step tutorial to see if it will make things better for you.

Help with Conditional Display and Validation

Version 4.1.1.00.23
Hello,
I'm having a difficult time with a conditional display and validation I'm hoping someone can help with.
Requirements:
When the Start Date (Datepicker) and/or End Date (Datepicker) change then display the Change Reason (Select List) and Change Description (Textbox)
If the page is saved without entering a Change Reason display a validation error message that the Change Reason cannot be empty (NULL)
What I've tried
Create a Dynamic Action on the Start Date
Event: Change
Selection Type:Item(s)
Items(s): P51_START_DATE
Condition: none
True Action Section:
Action: Show
Fire on Page Load: Checked
Show all page items on the same line: No
Affected Items Section:
Selection Type:Item(s)
Item(s): P51_CHANGE_REASON,P51_CHANGE_DESC
I've also created a Dynamic Action with similar settings for the P51_END_DATE.
I created a Validation for the P51_CHANGE_REASON as Function Returning Error Text:
DECLARE
    v_start_date    work_items.start_date%TYPE;
    v_end_date      work_items.end_date%TYPE;
BEGIN
    SELECT start_date
          ,end_date
    INTO   v_start_date
          ,v_end_date
    FROM   work_items
    WHERE work_items_id = :P51_WORK_ITEMS_ID;
    IF ( (v_start_date != TO_DATE(:P51_START_DATE,'DD-MON-YYYY') OR v_end_date != TO_DATE(:P51_END_DATE,'DD-MON-YYYY') ) AND
          :P51_CHANGE_REASON IS NULL ) THEN
        RETURN 'Change Reason must have a value';
    END IF;
END;
The Issue
I tried to create another Dynamic Action to hide the P51_CHANGE_REASON and P51_CHANGE_DESC fields on page load, but when either of the date fields are changed and the validation is fired the P51_CHANGE_REASON and P51_CHANGE_DESC are hidden again.
There are two buttons to submit the page: 'SAVE' will submit the page and stay on the page and 'SAVE_CHANGES' will submit the page and branch to the previous page (which is a report with EDIT buttons to edit the record).
I can't get the page load Dynamic Action to NOT fire when the validation is fired.
I hope this is clear and if not what information can I provide?
Thanks,
Joe

Phil,
Thank you for looking at this.
Yes if the Change Reason is NULL when the edit page is displayed then the Change Reason and Change Description fields are hidden. If the Start Date (Datepicker) and/or End Date (Datepicker) change then display the Change Reason (Select List) and Change Description (Textbox). If the page is saved without entering a Change Reason display a validation error message that the Change Reason cannot be empty (NULL).
The problem I'm having is that if no Change Reason is entered and the page is saved thereby firing the validation the Change Reason and Change Description fields are hidden again (because of the On-Load Dynamic Action to hide them). So now the user can't put in a Change Reason...unless they change one of the date fields again which isn't going to be accepted.
Is there a way to determine if a validation error was fired and be able to use that on the On-Load Dynamic Action to hide the two fields? Something like...If the validation fired then don't run?
Please let me know if I'm still confusing you.
Thanks,
Joe

Help with simple pause and speed titles

New at imovie.
I can't figure out how to get a title to appear over a black screen whether bouncing or appearing in the center and stay there. Either it goes to fast or there is this long pause after it arrives to fast and leaves to early.
Where can i get some detailed information on the pause and speed options.
Thanks

Did you download and install the Windows Support software? If you did, did you use the Boot Camp Control icon to set up the trackpad how you want it?

Try a reset: hold down the home button along with the power button until you see the Apple, then let go.

What are the differences between the Apple 64GB iPad Air with Retina Display and the Apple 64 iPad with Retina Display MD512LL/A 4th Generation

what are the differences between the Apple 64GB iPad Air with Retina Display and the Apple 64 iPad with Retina Display MD512LL/A 4th Generation ?

The iPad with retina display only comes in the 16GB version and it has the A6 processor which is a step down from the Air model. Having said that, I stream movies on my iPad 3 with retina and it has the A5 processor and the movies stream just fine as does everything else that I do on the internet.
If 16GB is enough storage for you, the $100 savings compared to an iPad Air model is a fair amount of money and that might sway me if I was just worried about saving some money. However, that's not my style. I always go for the largest capacity that I can afford and the faster processor if I have the choice.
Having said that, if it were me, I would select the 32 GB iPad Air. But in spite of the information that you provided in which you want to base your decision, only you can be the judge of what will be best for you, and remember that you cannot add storage capacity to the decide later. You can purchase external WiFi drives if you need the storage, but to me, that takes away from having the really small footprint and portability of only having to carry the iPad around gives you.

As a stockholder, I would like see the development of iTV with Retina display and integrating Siri control, internet access, and iTunes apps. This new product would be a large screen, thin wall mounted television, much like a oversided iPad.

Do you think this product is possible?

In general theory, one now has the Edit button for their posts, until someone/anyone Replies to it. I've had Edit available for weeks, as opposed to the old forum's ~ 30 mins.
That, however, is in theory. I've posted, and immediately seen something that needed editing, only to find NO Replies, yet the Edit button is no longer available, only seconds later. Still, in that same thread, I'd have the Edit button from older posts, to which there had also been no Replies even after several days/weeks. Found one that had to be over a month old, and Edit was still there.
Do not know the why/how of this behavior. At first, I thought that maybe there WAS a Reply, that "ate" my Edit button, but had not Refreshed on my screen. Refresh still showed no Replies, just no Edit either. In those cases, I just Reply and mention the [Edit].
Also, it seems that the buttons get very scrambled at times, and Refresh does not always clear that up. I end up clicking where I "think" the right button should be and hope for the best. Seems that when the buttons do bunch up they can appear at random around the page, often three atop one another, and maybe one way the heck out in left-field.
While I'm on a role, it would be nice to be able to switch between Flattened and Threaded Views on the fly. Each has a use, and having to go to Options and then come back down to the thread is a very slow process. Jive is probably incapable of this, but I can dream.

I plan to buy and use a MacBook Pro with Retina display and I already own and use the PS CS 5 on my PC window-based. How can I obtain a copy of CS 5 for my MacBook Pro?
Message was edited by: CHARNCHAN. That is without having to buy another copy for the Mac!

Not sure why you'd want CS5 for your new Mac with Retina display.
Retina support was first added to Photoshop in CS6 version 13.0.3
http://blogs.adobe.com/jkost/2013/01/retina-display-support-and-photoshop-cs6.html
So, assuming you own standalone Photoshop CS5 (and you're running at least Windows 7 on your PC) then your best option - for optimal display on your Mac - might be to subscribe to the Photoshop Photography Program for $9.99/month
https://creative.adobe.com/plans/offer/photoshop+lightroom?sdid=KIHZP
Then you'll get Photoshop CC + Lightroom 5 + extras and you can run them both on your Mac and Windows (2 installs permitted regardless of operating system) for the same $9.99 monthly fee.
If you don't want to subscribe then your other option would be to buy a separate CS6 license for Mac (paying full price).

What generation of iPod touch do you have? If you don't know, see:
http://support.apple.com/kb/HT1353
If you have an first-generation iPod touch, it can only go to iOS 3.1.3 and hence will not run the Facebook app. If you have a second-generation iPod touch, see:
