Need help with Bind variable in AF LOV query

Hello

I have a problem with the binding variable, if I use bind variable in the VO LOV query then my result does not come, if he has do not bind variable it works fine and if I use the variable binding in the LOV search option then it works fine but if I hide the bind variable and set the value in the prepareSesstion AM method the LOV does not return any value. I try to return the values that also all values are also coming, but these values are not the attribute query AF setting.

Query is:

Select substr(d.description,0,40) description
cm_system_users has
b cm_user_responsibilities,
cm_responsibility_processes c,
cm_processes d
where a.nt_login =: B_NT_LOGIN
and a.user_id = b.user_id
and trunc (sysdate) between b.eff_date and nvl (b.exp_date, sysdate + 1)
and b.RESPONSIBILITY_ID = c.RESPONSIBILITY_ID
and c.process_type = d.process_type
and d.enabled_flag = 'Y' order of d.arguments_flag

FOLLOW the method:

CmProcessViewImpl vo = getCmProcessView();
String nt_login = getUserPrincipalName();
vo.setNamedWhereClauseParam ("B_NT_LOGIN", nt_login.toUpperCase ());
vo.executeQuery ();

Can someone help me with this. It is urgent for me.

It's a bit underdescribed. IIUC, the purpose of the notice is used as a target for a correct view accessor? (Otherwise, you will have to be more explicit about what you mean by "LOV query".

If I'm right, there are two possibilities:

(1) you use an instance of VO in a module shared application instance. If so, make sure that your code is in the prepareSession() for the class of application that module if it is dependent on session (as seems to be below), you must make sure that the module of the application instance is shared in the session scope.
(2) you have based the view accessor directly on the definition of the VO. This creates an anonymous instance of VO; I don't think there is a way to use prepareSession() to set a variable of liaison on such a forum (which will not be created until the accessor is first used). Pourriez be able to shoot with to put a similar code in the view object create() method class, but I've not tested this.

If your code is in your module class application primary (as opposed to the class for a shared of AOS instance), the problem here is that getCmProcessView() returns the instance of VO data module of this application instance design-time model, which is never used by accessors of the view.

Also, why do you need to do this in prepareSession() rather than at the level of the accessor to view? I believe you can get the user name (for the view accessor) with the groovy expression

viewObject.DBTransaction.session.userPrincipalName

or maybe just

DBTransaction.session.userPrincipalName

(despite this DBTransaction involving, it returns the username web app, not the DB user name).

It is a declarative 100% solution, if you don't count the Groovy expression as not declarative.

If you are afraid of a user who is running the LOV (somehow) before the value of the bind variable is preparing, just make sure that the binding variable is marked "required."

problem with bind variables in the SQL query view object

Hi all
I use JDev 11.1.2.4.0.
I have a problem with bind variables in the SQL query view object.
This is my original SQL
```
SELECT sum(t.TIME) , t.legertype_id
FROM LEDGER t
WHERE t.nctuser_id = '20022' 
      AND to_char(t.insertdate,'YYYYMMDD') in ('20130930','20130929')
group by t.legertype_id

WHERE   t.nctuser_id = '20022'
    AND to_char(t.insertdate,'YYYYMMDD') in :dddd
group by t.legertype_id
```
Davis here is a variable of Type liaison: String, updatable and necessary.
I try to deal with Davis as ('20130930 ', ' 20130929') hoping the view object, run as my original SQL.
But failed. The view object retrieves 0 line after that I run.
Why?
Thank you! ('2original SQL0130930', '20130929') ('20130930 ', ' 20130929')

A variable binding cannot be used as this is why you must use years table. Check decompilation binary ADF: using oracle.jbo.domain.Array with ViewCriteria to see a solution.

Need help with choice variables remain in the new session
I have a set of approx. Flash to the top with several variables. Y at - it a simple action script that will allow the user to maintain their choice after the closure of the .swf and revive it?
Thanks in advance for your help.
How do check you if these components have been checked or ticked. in fact, I probably don't want to know that.

you really recommended to use a listener to detect when your components have changed and then you can use the modified method to define your variables and update your sharedobject.

Need help with auto-fill the fields

Hello
I need help with a form that has multiple pages. I have some areas I are duplicated in my document. How I got these fields auto fill throughout the form/paper? For example, I'm going to fname lname, address, telephone, etc... How can I get these fields automatically on the other pages of the form? Is this possible? Any suggestions are welcome.
Thank you in advance.

If it's just a fill operation then make sure the fields have the same name. Then set the binding to the global level and all the fields with the same name will get the same value.

I'm suddenly needing help with my browser Firefox (6.0.2)

Hello
I'm suddenly needing help with my browser Firefox (6.0.2)

(OS: I use Windows XP).

When I open the browser, I don't see is a totally white screen of white, with all the toolbars at the top.

I know that my physical connections are very good: I have tested the modem, turned the pc market etc and I can also receive/send emails.

This problem started today, September 8, 2011 and has never happened before.

Is it a coincidence that Firefox itself to day before I disconnected yesterday evening? Could this be something to do with this particular new update?

I also noticed that just before I "opened" Firefox, I now get a small box indicating:

[JAVASCRIPT APPLICATION]
Handl exc in Ev: TypeError: this oRoot.enable is not a function

This never appeared before - I hope that it offers a clue has what is wrong.

The browser not be stuck in Mode safe, said by the way.

Of course, I can't find solutions to the problem on the internet, I don't physically see all Web sites!
(A friend sends this request in my name from their pc)

Any light you can throw on this problem of confusion would be much appreciated. I'd rather not have to uninstall and reinstall Firefox if possible.

If the only option is to uninstall Firefox and reinstall from your site, I'm also in trouble (I can not see the internet or download).
In this case, would you be able to send the .exe file as an attachment to my e-mail address? In the affirmative, please let me know and I'll give you more details.

Thanks in advance.

One possible cause is security software (firewall) that blocks or limits Firefox or plugin-container process without informing you, possibly after the detection of changes (update) for the Firefox program.

Delete all rules for Firefox in the list of permissions in the firewall and leave your firewall again ask permission to get full unlimited access to the internet for Firefox and the plugin-container and the update process.

Hello

The link below is a guige to install a video card in your Pc. In particular, it seems that you will have to perhaps specify the location of the new card in the bios and save this change before you install the new card - see step 4 in the guide on the link below. If your new card fits into the PCI Express x 16 slot, you will need to define PCI Express in the bios and save the changes.

I need help with an installation failure to interpret and troubleshoot a Setup log.

Background: A few years ago, many editors of cinema used Final Cut Pro 6 (also contained in Final Cut Studio 2) for their editing projects. Shared Apple Final Cut X uses a different format that is not compatible with FCP6. Sometimes, these editors are called to work on a few historical projects that have been published in FCP6 and need this version to run now.

Starting with OS X Lion, FCP6 would install not in Lion and thereafter.

According research by Jeremy Johnston as noted on his blog, he discovered that Apple has inserted a file in the folder CoreServices in the Library folder of the system folder that causes versions the version Final Cut Pro X (and other older Apple programs in the same situation) do not settle. He suggested changes to this file that would seek to prevent interfering with the installation of FCP6 in Lion, many users of final cut PRO 6 were successful in their efforts to install in Lion and work with it.

Later in a discussion update on installing FCP6 in Mavericks, HawaiianHippie determined that the simplest way to perform the installation of FCP6 was simply copy this file and remove it from the system folder, install FCP6 and then restore the copied file:

I used this method with success to install FCS2 in Yosemite:

[click on images to enlarge]

However, in my attempts to install FCS2 in El Capitan, it fails in the last 5% to install the first DVD:

First of all, I need advice on how to display an extremely large Setup log in this thread (on MacRumors, it is a method to insert a 'code' in a small box that can be the object of a scrollbar if necessary to read all along). I am unable to find such a method to post here.

Then once approved, I need help to determine which component is causing the installation to fail and perhaps this element can be omitted from the installation:

If this element is not required, then maybe FCP6 can be installed successfully without it. And if that omitted element is necessary, perhaps a manual method to install it can be determined by pacifists.

It is my goal to help those who need to install and use FCP6 on their new Macs running El Capitan.

Here is the post on MacRumors with pre-installed Setup log:

Need help with the port forwarding for a XBox remote Streaming

I have a router R6200v2 and need help with port forwarding.

I came across this set of instructions for setting up stream port forwarding XBox remotely from anywhere

http://kinkeadtech.com/2015/07/how-to-stream-Xbox-one-to-Windows-10-from-anywhere-with-Internet/

I have no idea when it comes to such things and I want to make sure I do it correctly without messing up my existing home network.

Port Forwarding and triggering Port pages setup look very different from what the guy uses. Can someone walk me through what I do to set up please?

Hi @varxtis,

You must enter them in the field for a start external Port and external completion Port. You will need to send individually except for the range of 49000-65000. The steps are as follows.

1. create a Service name (it could be something else that you cannot use the same service name twice. Ex. XBOX1, XBOX2 and so forth.)

2. Select the type of service (TCP, UDP or both)

3 entry 5050 times a start external Port and external endpoints.

4. Select the IP address of your XBOX.

5. Select apply.

6 do the same for other port numbers. To the beach, use 49000 for the external departure Port and for the external completion Port 65000.

Kind regards

Need help with network home using Airport extreme

I need help with my home network. I'm not very aware when it comes to all things network. Here's how my network is currently set up.

Cable modem to Airport Extreme for Gigabit Switch. Cables come out of the switch to all areas of the House. I have 2 other extreme airport connected in other rooms of the House directly on the wall that dates back to the switch. I hope I am explaining that properly.

My problem is that this seems to have caused some of my connections cable does not work. When everything is configured, it has worked well. All connections in the House worked. Then we have disconnected one of the extreme airport and moved to another location in the House to have the best wifi coverage. Since that time, a lot of the ethernet wall plugs are not working. For example, when I plug in my Macbook Pro in making ethernet in my kitchen, it says connected but it has an assigned ip address and cannot connect to the internet.

Any help you can provide would be great.

I would like to get the return tech to help you to...

But it is likely that something (or someone) has tampered with the settings.

The layout is fine... but you can cause problems with the network by creating a loop.

This can happen because the AE you moved is connected wrongly... somewhere in the network it is connected to the switch again.

Or AE is set to expand wireless... It's FAKE... It will loop the network on the back main EI wireless.

Unplug the two AE you have that function as extensions...

Turning off everything else... then it works again...

Do it in this order.

Modem... Wait 2 min

AE... Wait 2 min

Switch.

Now check that the network is working properly... power of customers in various locations and make sure everything is good.

If so, then manually reset the two AE of factory and redo their installation.
