How to restore session item values

Hi,
We have a request form which has more than 50 fields and some hidden items which are calculated depending on other items. We have to implement SAVE request feature so that the user can save their partially filled request. We are storing these fields data in more than two tables and not storing some hidden item values. Our idea is to store that form page current session values and restore them when ever user wants to complete request. Is there any apex views which will have all these data. Please suggest how can we do this.
Thanks in advance.
Regards
Ram

Hello Ram,
>> Yes we have seperate SAVE button
That’s good, as it allows you to use these buttons to condition the PL/SQL processes, differentiates between the temporary and permanent actions.
>> Our idea is to have temp table to store all the items and their values in the page when the user clicks on the SAVE button
You are using ‘table’, in a single form, so I assume you refer to a single (temp) table. With careful planning of this temp table, it might be possible.
To use a single temp table, it must contains details of the item name, value and the application page it defined on (although this information can be derived from the item name, if you are using APEX item name convention). The page items should be defined with a Source Type of ‘Database Columns’, and in this case, you can use the APEX_APPLICATION_PAGE_DB_ITEMS view to track them. Using this view, you can retrieve the relevant items for the current page, and then, dynamically build a PL/SQL insert/update statement to save the items into the temp table; or a PL/SQL select statement to fetch relevant items from the temp table and populate the page items.
These are not trivial processes to build, and as you are going to use a single (generic) temp table, you will have to code all the temp/permanent DML statement yourself, but it seems doable.
You might also want to check the WWV_FLOW_DATA table, which holds the session state data, and see how it was defined (for example using CLOB as the item value datatype, to allow you to store different types of APEX item values in a single column).
Hope this helps,
Arie.

How to pass session variable value with GO URL to override session value

Hi Gurus,
We have below requirement.Please help us at the earliest.
How to pass session variable value with GO URL to override session value. ( It is not working after making changes to authentication xml file session init block creation as explained by oracle (Bug No14372679 : which they claim it is fixed in 1.7 version Ref No :Bug 14372679 : REQUEST VARIABLE NOT OVERRIDING SESSION VARIABLE RUNNING THRU A GO URL )

How to pass Application Item value in Javascript function.

Hi,
I have the following javascript in the HTML Form Element Attributes properties
I am on Page1 and passing P1_DEPT_NO page item value. This is working perferctly fine and I am able to get the exact value of the page item
onchange="javascript:function1($x('P1_DEPT_NO').value);"I am on Page1 and passing Application Item G_DEPT_NO value.
The problem here is, I am not getting the Application item value inside the javascript function.
I tried using alert(); and it's giving me value as undefined
onchange="javascript:function1($x('G_DEPT_NO').value);"Just want to know, how to pass the Application Item value in Javascript.
Thanks,
Deepak

Deepak,
I am not an expert at Javascript, but the suggestin I made was because javascript is a case-sensitive language.. and therefore onChange is not the same as onchange.
Not quite sure if that is causing the problem.
Application items are not associated with a page and therefore have no user interface properties.
Therefore, as mentioned in another post, the rendering would not work for application items.
If it is for a single item, used only in this page, you could create a hidden page item and use it fo your purpose
If you still want to look at application items and AJAX, This page contains examples of using AJAX to solve problems like the one you mentioned.

How to restore sessions after upgrade

Just upgraded to FF 33. Previously I had two windows open. Upon restart only one opened, with all its tabs intact. I would like to recover the other window as well. "Restore session" is either grayed or missing on menu and start pages. Is there a way to recover the second window.

Usually, the History menu will list closed windows you can restore below the grayed out Restore Previous Session. Anything listed?
Before closing Firefox, please back up your session history files to a safe location for potential recovery/salvage operations.
You can open your current Firefox settings (AKA Firefox profile) folder using either
* "3-bar" menu button > "?" button > Troubleshooting Information
* (menu bar) Help > Troubleshooting Information
* type or paste about:support in the address bar and press Enter
In the first table on the page, click the "Show Folder" button.
In the window that launches, scroll down and double-click into the '''sessionstore-backups''' folder. Save all files here to a safe location, such as your Documents folder. We may be able to use them to recover your lost tabs.
The kinds of files you may find among your sessionstore files are:
* recovery.js: the windows and tabs in your currently live Firefox session (or, if Firefox is closed, your last session)
* recovery.bak: a backup copy of recovery.js
* previous.js: the windows and tabs in your last Firefox session
* upgrade.js-''build_id'': the windows and tabs in the Firefox session that was live at the time of your last update
You might also find files Firefox created if it could not update recovery.js (but since Firefox 33 is so new, I don't know what they would be named).
Could you take a look at what you have and the date/time of the various files to see whether you think any of them would have the missing window?
Note: By default, Windows hides the .js extension. To ensure that you are looking at the files I mentioned, you may want to turn off that feature. This article has the steps: http://windows.microsoft.com/en-us/windows/show-hide-file-name-extensions

How to restore the items lost before i backed up my ipod

Well I traded in my IPod after I cracked but before I did I backed it up so all of my items wouldn't be gone. I could not restore my new IPod right away so I waited a week. In that week I accumulated a lot of pictures and notes. Yesterday I decided to finally restore my IPod. When I did I found that all of the pictures and notes I had saved in that week when I had just gotten my IPod had been deleted and replace with all of my old data. I was wondering if there was anyway to restore those pictures I had saved during that short period of time. Thank you and have a wonderful day

If you did not backup during that time then the data is gone. You may be able to get your phtos taken by or saved to the iPod backup by getting them from your PhotoStream. For how see the PhtosStream topic of:

How to restore calendar items from Entourage 2008 after upgrade to Lion (10.7.5)?

I held off upgrading to Lion because I had a bunch of old email I wanted to convert first. But now that Apple is no longer offering security updates for Snow Leopard, I decided to take the plunge. Unfortunately, after the Lion upgrade most of my calendar items in Entourage 2008 disappeared (and those that remained appeared in duplicate).
I think I should be able to access an uncorrupted version of my Main Identity folder for Office 2008 … because I have an Automator workflow that creates a daily backup, and that backup should be available through Time Machine. I turned off Time Machine after this calamity so that I wouldn't overwrite my Entourage Backup folder.
I need the July 8 or 9 version of: ~ / Documents / Entourage Backup / Main Identity.
But when I select the Entourage Backup folder and open Time Machine, all the Finder windows behind the current one go dark and I can't move backward toward an earlier date (I've done this with Time Machine turned off and on). This makes me think the Entourage Backup folder has not been getting backed up recently, or perhaps ever. Ugh.
When I check my Time Machine preferences, only the following items are shown as excluded from backups:
So it seems I should be in the clear and able to access Entourage Backup.
Any idea what I'm doing wrong in trying to restore from Time Machine? Or anything else I might be doing wrong?
Many thanks.

When I check my Time Machine preferences, only the following items are shown as excluded from backups:
Not sure how any of this relates to a Time Capsule....one of the hardware products that we support in this forum.....but we will try to help.
Main Identity is located as follows on your Mac:
Macintosh HD > Documents > Microsoft User Data > Office 2008 Identities > Main Indentity
Unfortunately, you have been excluding Microsoft User Data from your backups, so there is nothing to recover or restore.

How to clear invalid item value?

Hi, All.
I have two items: selectOneChoice and inputComboboxListOfValues. The second item list of values depends on the first item selected value. When the value of the first item is changed, the second item should be reset. I do this by
calling setValue(null) on the second item. The partialTriggers property of the second item is set to the first item id. If the second item has a valid value, then everything works well. But if the second item has an invalid value, for
example, the user after entering an incorrect value, clicks on another item, the setValue(null) does not reset the value.
Moreover, it is possible that a user saves to the database invalid data. For example:
1. Select a valid value on the second item.
2. Remove some characters making the invalid value.
3. Go to some other item by clicking the mouse.
4. Change value in the first item. (At this time will invoke setValue(null), and the list of values of the second item will change.)
5. Edit the value in second field to the value set in the first paragraph (this value is not valid after changing the value in the first element).
6. After that the document can be saved, no further checks are not happening.
Version of JDeveloper is 11.1.2.4.
How to set null value and how to ensure that in the second item it was impossible to enter not valid value?
Regards,
Alexey

OK, I looked into the issue. There are two problems:
1) your data model does not check the entries in the SOME_DOCUMENTS. You only check the FK against the master tables. You need to check if hte combination of the keys are valid. On solution would be to use model driven dependent lov. Check Andrejus Baranovskis's Blog: Cascading LOV's in JDeveloper 11.1.2.3.0 for a sample. Next the VO you use is based on multiple EO which is not necessary if you use Andrejus's approach.
2) There might be a bug in the af:inputComboboxListOfValues in this scenario when you you allow to enter values (or parts of it) in the inputText. However, if you validate the keys correctly, you can't insert something invalid. This problem has it's root in your data model. If you use the dependent lov and don't allow user input you can't change the selected value to something invalid. So my advice is to use dependent lov and don't allow input in the inputComboboxListOfValues (set editMode='select'), the user can still search or select the value, but only the valid ones.
The inputComboboxListOfValues error need some more investigation which need more time. I'll see if I find out something more.

How to get selected item value and display text in selectOneChoice ?

Hi
Thank you for reading my post
I bind the a selectOneChoice component to my backing bean so i have an object which represent this component in the backing bean.
now i need to find which item is selected by use , i know that i can use
getSelect_service().getValue.toString() , but it will return the value of the selected item, how about its display text ?
I should say that i create an static list for selectOneChoice items.
thanks

Using JDeveloper 10.1.3.1, freshly downloaded off OTN. I used the following code to try and identify the problem you are encountering. I attempted to use a valueChangeListener in combination with af:selectOneChoice components that use SelectItems and the singular SelectItem. I could not reproduce the error in either case. Please post more information about your development environment.
          <af:selectOneChoice label="Label 1"
                              binding="#{backing_test.selectOneChoice1}"
                              id="selectOneChoice1"
                              valueChangeListener="#{backing_test.valueChangeListener}"
                              autoSubmit="true" immediate="true">
            <af:selectItem label="1" value="1"
                           binding="#{backing_test.selectItem1}"
                           id="selectItem1"/>
            <af:selectItem label="2" value="2"
                           binding="#{backing_test.selectItem2}"
                           id="selectItem2"/>
            <af:selectItem label="3" value="3"
                           binding="#{backing_test.selectItem3}"
                           id="selectItem3"/>

How to refresh list item values before report is run?

We have two SELECT LIST items (drop boxes) on our report. One SELECT LIST has values of "World Region" (e.g. NORTH AMERICA, SOUTH AMERICA, EUROPE, ASIA)
the other SELECT LIST has values of "Subregion" (e.g. NORTHERN EUROPE, SOUTHERN EUROPE, SOUTHEAST ASIA etc...)
The values in the Subregion list are dependent on the value that is chosen from the "World Region" List. Can someone tell up how to update the values in the Subregion list BEFORE we submit the page? We can get these values to update (via sql query) when the page is submitted but that is only happening after the report gets run- which is not what we want. We want the user to select a Region from one SELECT LIST and then see all the qualifying Subregions for that Region in the Subregion SELECT LIST. Only after both Region and Subregion have been selected do we want to run the report. Thank for any help on this.

hey john--
john) things like Scott's reference to "The name of the LOV Item". What does this really mean?
raj) in htmldb there's a concept of items at the page and at the app level. page level items have ui component associated with them. in scott's explanation above, he's talking about using a page-level item with a "Display as" type of "select list w/submit" for your first select list. in that case, he's suggesting you have one select list item drive the values of another. when the self-submitting select list submits the page, it sets an htmldb built-in variable called :REQUEST to the name of the self-submitting select list item. in your follow-up post's example, that'd be "REGION_LIST". scott was explaining how you could control the functionality on your page by adding conditions to things like...
:REQUEST = 'REGION_LIST'
...or using declarative Condition options like "Request = Expression 1" and then putting the string "REGION_LIST" in that Expression1 field. so in your case, you have a report region that you don't want displayed until the user's done selecting from your Subregion list. an easy way to handle that would be to add a hidden item (where "Display as" is set to "Hidden") to your page, for example :P1_LAST_REQUEST, to store the last value of :REQUEST. put a Computation on your page that populates :P1_LAST_REQUEST with :REQUEST each time the page is submitted. then put a Condition on your report region that makes it only render when :P1_LAST_REQUEST != 'REGION_LIST'. so this way your users can select a Region and have the page submit itself. the page will then redraw with the values of subregion list correctly populated (you'd presumably use :REGION_LIST in your subregion LOV query to achieve the filtered values) w/o your report region displayed. the user would then select a correct subregion and click some sort of "run my report" button. this time when the page redraws, :P1_LAST_REQUEST would be set so something other than "REGION_LIST" (it'd be set to whatever you named your "run my report button") and so your report region would display as desired.
hope this helps,
raj
