Display Button Conditionally

Hi,
I am a newbie to application express, so i'm sorry if this is a stupid question.
I have a wizard which contains multiple pages. The wizard is basically like a installation wizard, where the first page is a list of check boxes, and users click what they want to do. For example if the XXX check box us checked, then it will branch to that page(which i have done) and that page will need to have a finish button on it. So my question is how do i display the finish button depending on the value of those checkboxes... the problem i have is i can refer to items in the other page, so how do i check the values of those checkboxes in order to display the appropriate buttons?
Thanks
Venus

The value of a page item is persistent, unless you explicitly clear page cache, so even 10 pages after, you can still refer to the value of the item containing your checkbox list.
So, if you want to make a button visibile depending on a value associated with a checkbox then you just need to ensure that the desired value is equal to a certain value or present in a list of values i presume in your case.
I mean checkboxes normally allow for more than one selected value, so you'll end up with a list of values separated by some separator, tipically a colon. In that case you just need to pick the condition "value of item in Expression 1 is contained within colon delimited list in Expression2" in the button conditional display definition.
I hope is clear...
Bye,
Flavio

MAKE BUTTON CONDITIONAL DISPLAY IN A REPORT BASED ON STATUS OF COL VALUE

hello,
can anyone help me out with this issue.
Like I have a normal SQL report with buttons update,delete,insert and I wanted to display these buttons conditionally based on the value of the "status" column.
For Example: if the status columnvalue is 'DEV' then only display the buttons otherwise don't display them.
thanks,
Orton

I would use a CASE statement in the select....
each CASE would be an img src tag for a different button if the button is an image.
does that make sense? I can include an example if you would like...

Button condition on page item and Validation error Conflict

Hi,
I have a select list page item and a button on page whose condition is based on the select list page item value(eg, If (:P2_item1='val1'){return true;}) with condition type=PL/SQL function returning boolean. This buttons submits the page.
It' coming fine in normal case. However, if I select some value val2 from the list and then click the button, and if there are any validation errors (like mandatory check or email check fail etc), then the button disappears because it evaluates the button condition based on the changed value(val2), but the page has not yet been submitted because of validation errors.
I think this can be solved if I create the button condition based upon database column value instead of page item as db col value won't change until the page is submitted.
This look like very basic use-case and I would like to know if there is any better solution to this problem.
Note: I am using Apex 4.2.1

I don't want to show/hide the button on the change of the page item lov value, so i am not using Dynamic action.
What i was is to make button visible based on a condition(which is based on page item), for which we have condition attribute of a button available.
This is a very common thing where a user chooses the button condition as Value of item/column in expression 1 is null/expr2. But what if the user changes the page item value but it doesn't get submit due to validation error. In that case, the button condition fails.
So, i guess i have to use column name in expression 1, can u tell how to do that?
Expression 1 = IF (:P2_STATUS='val1') then return true;
How to change the above to use db column 'status' instead? Any direct way(like #Status#) or I have to query db to get it using select.
Any alternative approach?

Computer shuts down when I click on the list or grid display button

I've uninstalled an reinstalled 3 times and instead of the computer shutting down when I start itunes as it was doing, it only does it when I click on the display as a list, grid or cover display button. However it seems to unistall some parts at the same time as I can't open it all afterwards (error message says its not installed). This started to occur after a couple of weeks of non use and when I last used it I purchased songs from itunes. I now have current version but didn't when it first statred to happen. Help!!

Okay ... we'd better have a closer look at the minidumps the PC has been producing to see if they can turn up any additional information on what we're dealling with here.
Open "My Computer", and see if you can find a directory called C:\Windows\Minidump. (That's where minidumps usually go on a PC, so long as the Systemroot hasn't been set to some other folder.)
If it's been collecting minidumps, there should be files in there with names like "Mini(number-numbers).dmp"
(If you have "Hide filename extensions for known file types" enabled in Windows, the ".dmp" extension may not appear on the dump files. The numbers in the file name will be different for each minidump, if minidumps are present.)
Once we've tracked down some minidumps, we can have a go at analysing them.
1. Download and install the Windows debugging tools from here:
http://www.microsoft.com/whdc/devtools/debugging/installx86.mspx
2. Go to Start, All Programs, Debugging Tools For Windows, Windbg
Once you open Windbg, you will presented with a blank screen.
3. Click on "File > Symbol File Path". Here you will enter the symbols
path. Symbols are needed to effectively debug.
The path will be:
SRVc:symbolshttp://msdl.microsoft.com/download/symbols
4. Enter in this path and click OK. Now, go to "File > Save Workspace"
so that your symbols path is saved for future use.
5. Go to "File > Open Crash Dump" and load the file.
(An "Open Crash Dump" screen will appear ... doubleclick "My Computer", doubleclick "Local Disk", doubleclick "Windows", doubleclick "Minidump", and doubleclick on one of the minidumps in there.)
You will/should get a message to save base workspace information. Choose no.
Now you will get a debugging screen. It takes a little bit to run it,
as the symbols have to be downloaded as they are needed.
After the "bugcheck analysis" part of the screen comes up, look for the component that seems to be causing the crash. (It'll say "Probably caused by" ...)
Let us know the precise name of the component. (Include any file name extensions like .dll or .sys.)
If you can, have a look at several of your crash dumps. Are all the crashes being caused by the same component? If not, could you let us know the names of the various components being cited in the various crash dumps?

How do you display the horizontal display button in iMovie 11

Can anybody tell me how to display the horizontal display button in Imovie 11 to display the project in one horizontal timeline as opposed to multiple rows?

It is in the top right corner of the Project pane - next to the Marker Buttons. It looks like 3 gray squares.

Safari 2.0.3 not displaying buttons or pictures

On many web sites, Safari doesn't display buttons or clickable images on web pages. I have checked the "display images when the page opens" preference item. I have tried emptying the cache and resetting safari and deleting the com.apple.safari.plist file. I know the buttons are there since with the appropriate preference set I can toggle through them, and they are all there on another Mac using Safari 2.0.2 on the same network.

(I'm jumping in here as a newbie to Apple's discussions, so please forgive me if my posting etiquette is lacking and feel free to educate me accordingly.)
I have been looking for weeks for the answer to Joe Veranth's problem because I am having the EXACT same issues with images not loading on sites that previously loaded perfectly. I am on a G5 running OS 10.4.6 and Safari 2.0.3. I am not behind a firewall. (Note: these problems are not occurring for me at work, where I run a G4 with the same OS and Safari versions. All the settings are exactly the same.) I have tried resetting Safari, changing settings for blocking/not blocking popups, loading images when page is called, trashing Safari prefs, etc. No luck.
I just tried andyBall_uk's advise and eliminated all my internet plugins, then restarted Safari. Nothing changed. Still no images. Even Apple's home page isn't loading right.
I cannot positively connect the death of my Safari images with any particular update or download. I do know it's gotten progressively worse over the last weeks. I am suspecting the latest OS security update may have had an effect. Comments?
Sorry so long-winded, but I want Joe and anyone else experiencing this to know you are not alone. If anyone figures this out your are a hero.
Until then, Firefox is the way to go.

Disabling Radio Button Conditionally is not working Well

Hi friends,
I have three radio buttons
<li>self
<li>New Hire
<li>On Behalf of
I will be showing this radio button conditionally according to the user who logs into the application.
Assume, suppose if a person 'A' enters into the application means he will be shown only these radio button options ---NH---,----OB----,----Self-----
Suppose, if a person 'B' enters into the application means he will be shown only these radio button options ----NH----,----Self---
If a person 'C' enters into the application means he will be shown only these radio button options ---Self---
I have restricted those radio buttons according to the users who enter into the application using their roles.
But my challenge here is once the user logged in and if he select anyone of the radio button means,
Example if he selects----NH---means, then ---OB----and -----Self---radio button has to disable and if he selects ---OB----means then ----NH-----and ---Self---has to
disable(vice versa).
I have also achieved the same using the DA.
With true action as: javascript Expression i have given the following codings( i have written the below DA for three cases, if the request_class_code is equal to
(NH,OB,S)
var enabled=$v('P22_REQUEST_CLASS_CODE');
if (!$u_SubString(enabled,'S')) $('#P22_REQUEST_CLASS_CODE_2').attr("disabled","disabled");
if (!$u_SubString(enabled,'NH')) $('#P22_REQUEST_CLASS_CODE_0').attr("disabled","disabled");
if (!$u_SubString(enabled,'OB')) $('#P22_REQUEST_CLASS_CODE_1').attr("disabled","disabled"); The above DA is working great only for the user who has the option of viewing three radio buttons in my form(i.e)(NH,OB,S).
For the user who has the option of viewing two or one radio button, it is not working properly(i.e)(NH,S) or(OB,S) or(S).
Why it is not working for the user with two options or with one option radio button means, the source of that radio button property is changing. Since i have taken
the source of my radio button in my DA only when the three options are present.
How i can solve this issue for the user who is having this two radio option or one radio option.
Hope you understood clearly about the problem.
Brgds,
Mini

Hi,
If I did understand what you like have this might work
var lVal = $v('P22_REQUEST_CLASS_CODE');
$('#P22_REQUEST_CLASS_CODE input:not([value="' + lVal + '"])').attr("disabled","disabled");Regards,

Hcm forms : Update display button not working

Hi experts
the update display button in my form is not working . i have changed the script coding , still its not working
Regards
Priya

Hi,
Update display button is not working means is it not triggerring the back end means you are not able to see any server roundtrip,
if so check whether you have inserted webdynpro script.
if not go to your form in sfp
then goto menu select Utilities->Insert Webdynpro Script.
then you will see one script generated automatically and you can check in Hierarchy Pallete with the name ContainerFoundation_JS under Variables.
save the form and activate and then click on Update Button.
Thanks,

Detect Display button gone!

This is a rather infuriating mess-up in Mountain Lion. My wife is an educator and has a class room projector she has to connect and disconnect to on a daily basis with her brand new Macbook Air.
The problem is that her Macbook Air will not detect the projector when she connects it.
The only way it will detect is if she either restarts the computer with the projector already connected or puts her computer to sleep and waits for to wake up and that sometimes works.
Where as in Lion or any other previous version of OSX in the past five years you had the option of a Display Menu button (also gone) up at the top of your screen that showed connected displays as well as a Detect Diplays option that would do the trick. To make things worse even if you go digging to the System preferences under Displays Preferences they completely removed the Detect Displays button!
The funny part is the Apple help menu still tells you click the Detect Displays button that doesn't exist.
How on earth do you take such a monumental step backwards with an OS upgrade by making settings more difficult than easier? Having to restart a computer to detect a display? As a Mac user I haven't had to do that in the past 10 years! Please return us all the display options that should be available under any circumstance period.

Well folks I did find a work around for the time being. Though it doesn't restore my options in the menu button I did uncover the Detect Displays button. I was looking at my post request and behold I saw a related article next to this thread that says OS X Mountain Lion: About the Display pane of System Preferences ( http://support.apple.com/kb/HT5369?viewlocale=en_US&locale=en_US ) in the article it shows that they did indeed hide the option but it can be uncovered. The funny thing is this article does not show up when I search for my problem.
Hold the OPTION key in the Display Preference pane and the Gather Windows button will transform into the Detect Displays button.
Here are screenshots to demonstrate what happens when you toggle the OPTION key off and on.
Again why on earth did they hide this to begin with or not include it in the Display Menu option at the top of the screen? I don't know and I hope they fix it. This is WAY TOO complicated of a solution for a simple function. Nobody is going to intuitively find the Detect Displays option.

ITunes display buttons in iphone4

I need help with iTunes display buttons in my IPhone 4. There is no 'more' display button with which I can switch the podcast and iTunes u display buttons with music and movies display button. The only four tabs displayed at the bottom of the screen in ITunes are podcasts, iTunes u, search and downloads. Please help

If you have created buttons in a region position they will all display horizontally.
If you make buttons that display within the region Items, you can display them in any way that you choose as with a normal item.

Display Button on Overview Screen of iView

Hello,
Would someone please help me understand how I can insert a 'Display' button on an iView? Basically the requirement is as follows:
The Personal Data iView is something for which I dont want to give Edit access to the users. I know I can disable the Edit button through iView personalization, and it works great. However, now the problem is the only 2 fields you can see on the overview screen are Full Name and SSN. Can we put a 'Display' button on the overview screen such that the user can view all the Personal Data fields, without having to go to Edit screen?
The same is the requirement for all iViews. Would someone please let me know how would this be possible without custom coding; if there is a way to do it.
Thanks,
Nakul

Jay,
Thanks so much for the answer!! Sometimes after knowing the answer, it feels it was so easy all the time; why did I not think about it!! ".
That defenitely solves the Personal Data issue.
Just before I mark this thread answerd and close it; another question:
The other past is, can I add another Button for Display apart from the Edit button? For some iViews I may want to have both Edit and Display buttons on the overview screen. How would I meet this requirement?
Thanks,
Nakul
