How to clear context before navigation?

Hi,
I have a Web Dynpro ABAP application running in the portal which display some data in a textedit depending on a couple of parameters. These parameters are captured using a selection screen in a BI iView and sent using a portal event.
Here's the problem : when the user navigates to another page and then back to the page containing the WD ABAP iView, the textedit element already contains some data (corresponding to the previous selection). It should be empty because the BI iView is initialized and no selection has been made.
Is there a way to invalidate the context when the user navigates to another page in the portal? I tried to use the WDDOEXIT method but it doesn't work.
Regards,
Pierre

If you add the IVIEW as a link inside your webdynpro and create an action link (instead of having the link outside the webdynpro) then your problem is solve.
you will have control between the WD an the external IVIEW, it will be required to call the IVIEW form the WD.
I just did that with a standard SAP iview that I have in my portal and it works fine.
thanks!

How to clear the cookie in midlet before quite the midlet?anyone?pls

i am fresh in J2ME . Can anyone teach me on how to clear the cookie in midlet before i quit from it?
I designed an application that require login and use session(cookie) management, i need to clear the cookie before or during i quit the midlet, so that the user will need to login again after quit from midlet. Can anyone pls assist me? i need it urgently!

I designed an application that require login and use session(cookie) management,How did you implement the cookies. This isn't a built-in part of J2ME. You have to implement it yourself (saving the cookie and resending it in future requests), so only you can know how to delete it.

Anyone know how to clear all details in iCal before syncing with Entourage? (Happy Sundays!!)

Answer .... delete all calendars in iCal but leave the Entourage one there! Don't delete that as there will be big trouble!

ODI - How to clear a slice before executing the data load interface

Hi everyone,
I am using ODI 10.1.3.6 to load data daily into an ASO cube (version:11.1.2.1). Before loading data for a particular date, I want the region to be cleared in the ASO cube defined by "that date".
I suppose I need to run a PRE_LOAD_MAXL_SCRIPT that clears the area defined by an MDX function. But I don't know how I can automatically define the region by looking at several coloums in the data source.
Thanks a lot.

Hi, thank you for the response.
I know how to clear a region in ASO database. I wrote a MaxL like the following:
alter database App.Db clear data in region '{([DAY].[Day_01],[MONTH].[Month_01],[YEAR].[2011])}'
physical;
I have 3 seperate dimensions such as DAY, MONTH and YEAR. My question was, I don't know how I can automize the clearing process before each data load for a particular date.
Can I somehow automatically set the Day, Month, Year information in the MDX function by looking at the day,month,year coloumns in the relational data source. For example if I am loading data for 03.01.2011, I want my MDX function to become {([DAY].[Day_01],[MONTH].[Month_03],[YEAR].[2011])}'. In the data source table I also have seperate coloumns for Day, Month , Year which should make it easier I guess.
I also thought of using Substitution variables to define the region, but then again the variables need to be set according to the day,month, year coloums in the data source table. I also would like to mention that the data source table is truncated and loaded daily, so there can't be more than one day or one month etc in the table.
I don't know if I could clearly stated my problem, please let me know if there are any confusing bits.
Thanks a lot.

How to clear just the computer name before getting image of the hard disk?

Hi,
I have a Win 7 PC with some applications installed on it and I don't have the installation files of the applications. Now I want to create an image of the C drive, and use it on other PCs. So I need to just clear the computer name and shutdown
the PC and use an imaging software to make an image of the C drive, so when I deploy the image on a new computer, on the first startup screen it'll ask for JUST computer name.
I tried to use sysprep but it look like clearing more data than I want (just PC name). Also the AIK solution look like I have to have the installation files of all the softwares that I want to have on my computer.
In one sentence: How to clear the computer name before getting image using a disk image tool (Acronis, Ghost,...)?

Hi,
Sysprep will do this job. But when the system boot up, it will generate new computer name.
In general, you need boot to win pe after you run systprep. I think you can create a USB bootable device.
In win pe, you can use ImageX or DISM tool to capture the image.
I'm not fimilar with the tools you referred since they are not from Microsoft, so I cannot give any direction about it.

ORDS 3.0 - How to set VPD Context before executing SQL Template?

I need to set a couple of attributes in an Oracle Session Context before the SQL/PLSQL template handler is executed, as we rely on Oracle VPD/Row-Level-Security for the data access.
Is there a hook/functionality in ORDS 3.0 where I can register a PL/SQL (e.g. set_security_context(authenticated_user)) procedure, so this 'set_security_context' procedure is executed before and for each execution of a SQL/PLSQL template handler?

I tried to log the request at Oracle REST Data Services (ORDS) but I could only start a new discussion: Possibility to register Pre-/Post-Procedures for an SQL Template Handler
As I mentioned there, the PL/SQL handler approach works for me as long as I have no or only little data to send back to the client (e.g. put/post/delete succeeded or an error message why the call failed).
If I need to return a lot of data from the PL/SQL handler I would need to, as far as I understand, to marshal the data to JSON and write it to the response body in the PL/SQL handler.
I don't want to do the marshaling, because ORDS does it better.
However, this works for me:
I write a pipelined stored procedure that takes as input the attributes I need to set in the session context. I then can reference it in the SQL handler:
select * from table(my_pipelined_function(:USER, ....)
Now the JSON/HTTP response is created by ORDS again.
I still needed to code a couple of lines, but it is way better than duplicating the functionality already existing in ORDS.
With the hooks it would be perfect because I would not have to write any code (apart from the procedure to set the session context attributes), just configure the REST services in ORDS.

How to clear text fields when the user navigates back to the screen

Hi,
Does anyone have any idea on how to clear the text input fields and dropdown boxes when the user navigates back to the screen, say for e.g. create screen?
My issue is that i have plenty of fields in the create screen within a form. Is there a way to avoid programaticaly blanking out every field and just do it at the form level using an api to reset to a state before the user entry?
Thanks

This code allows you to make it more generic, and you would need to tweak it if there are more than TextInput controls, but it should provide some ideas.
As far as using states, you could use SetProperty to set the text to empty, but that might be messier.

HI Experts,
Unable to process the file in SXMB_MONI as a result the files are getting strucked with the QUEUE and now how to clear this queues for processsing the file...
and another i have configure the server with 611 client but while executing the client of the server is showing 001 and we didn't observe initially as it is working fine but when we observed now it is found
is this has an impact..
do we need to do any other certain configurations at the Server end..
regards,
Kishore

> There is no URL in SXMB_ADM, how to provide an url there, and even before we didn't get this problem as the files are successfully processsing for the past 3 months in PDN, and now we are getting this problem.
>
Hello,
I have understood your problem but you are not following the steps which we are mentioning here.
For your above problem you need to follow ONLY step no1 & 2 mentioned in the blog since steps are common for acitvating the proxy and thats way you are getting confused that why I am asking you to follow that blog.
In the blog step 1 will simply help you creat the RFC destination.
Step 2 will help you to use the above RFC destinaiton as an url.
In opionion if you resolve this problem first then it will be easier to solve your queue problem.
Please let me know if you need more help/clarification in this regard i will help you.

How to hide read mode navigation in acrobat xi permanantly

How to hide "Read mode navigation" . In my application i am opening pdf file in light box window where i disable right click to protect download and print pdf file( only View ). but This Read mode navigation is appearing automatically when we put curson on file even if we protect the document. I have purchased Acrobat professional xi to created protected acrobat file by disabling menu tool bar but there is no option to hide readmode navigation. Please let us know how to hide this.
Thanks,
Nagendra

If you want the form "flattened", that is all form fields converted to PDF context, you need to use some JavaScript to flatten the form fields. This will remove all form functionality. It will not prevent editing by Acrobat's text touchup or object tools.
The "submit" button is used by other users to sent the PDF form data to a central collection site or email address where the sender or provider of the form can collect the submitted data.
You could also use a digital certificate to sign the form and lock the fields. The signature will also verify that no changes have been made to the PDF since it was signed and one could also see what was changed.

How to clear a private static class attribute once it's been created?

<pre>I'm working with an instance of a complex Class object that has been created using the function module HRXSS_CAT_APPLICATION_INIT. The Class object that I am trying to work with is CL_XSS_CAT_BUSINESS_LAYER and in particular its Static Private component attribute PROFILE. 
The issue that I am having is that the first call of this function module creates and populates the Static Private component attribute, PROFILE, for the instance of this Class and I do not know how to initialize it once it's been created. The PROFILE attribute is an object reference to an instance of Class CL_XSS_CAT_PROFILE. 
I want to reset/intialize this Static Private component. I can then call a Class Method with different parameters so that it repopulates PROFILE with different attributes. There is no Public method to do this in CL_XSS_CAT_BUSINESS_LAYER and even the Private method INIT_PROFILE, the logic first checks to see if the PROFILE component is initial before creating a new PROFILE object instance. All the Attributes of the CL_XSS_CAT_PROFILE object are Static and Private.
 
I would appreciate any insight anyone might have in how to reset/initialize this Class component attribute. 
Thanks much,

OK...I apologize but I did not dig deep enough to see that the Enhancement Framework allows for the addition of Methods to Classes/Interfaces. Most of this ABAP OO stuff is still quite new to me so I'm struggling with syntax and what is and isn't possible based on how everything is declared. I guess now that I know I can do this I am having some problems understanding how singleton Class objects work and how to 'reset' them.
The Class instance based on CL_XSS_CAT_BUSINESS_LAYER has a Static Private attribute PROFILE that is an object reference to the singleton Class instance CL_XSS_CAT_PROFILE.
The singleton Class instance of CL_XSS_CAT_PROFILE has all of its attributes set to Static Private. If you look at this Class in SE80 you see that one of its attributes is also called PROFILE and is an object reference variable to itself.
So the issue I am having is how to go about 'initializing' this singleton object so that I can 'recreate' this singleton object using a copy of the existing S
I used the enhancement framework to create a copy of the CL_XSS_CAT_BUSINESS_PROFILE Instance Private Method INIT_PROFILE , called in INIT_PROFILE2, but I am not sure how to 'clear/reset' the instance of the CL_XSS_CAT_PROFILE object.
Since PROFILE is an attribute of the CL_XSS_BUSINESS_LAYER object, I thought that a simple CLEAR PROFILE would reset the object but this is not the case. Within this method the FREE clears the value of the reference variable PROFILE but as soon as you step into the method me->init_profile, the value of PROFILE goes back to what it was. I need for all of the CL_XSS_CAT_PROFILE instance attributes to be reset or initialized so I can fill them again. I think I'm getting confused on the scope of things...should I be enhancing the CL_XSS_CAT_PROFILE Class with 'setter' methods so I can initialize all of the Static Private attributes that way instead of trying to clear all the attributes at a higher call level?
Any assistance with helping me with my thought process or approach to this would be much appreciated.

How to clear the hung calls in CUBE?

Also, I tried enabling media inactivity timer but it would clear only the calls in 'Connected' status If I understand correctly.
how to clear those hung calls? and what could be the cause of it?
Any help would be much appreciated.
Thanks in advance
Suresh

Suresh have you tried this:
ip rtcp report interval 5000
gateway
timer media-inactive 5
The challenge you may face is that the media inactivity was not configured before this call started, hence it cant activate the time for this particular call...
Give it a go, lets know if it works. Even if it doesnt I suggest you enable this on your CUBE going forward, so you dont haver hung calls in the future
example: You can use the debug ccsip events to see the media inactivity timer kicking in for a call...
Router# debug ccsip events
00:04:29: sipSPICreateAndStartRtpTimer: Valid RTP/RTCP session found and CLI ena
bled to create and start the inactivity timer
00:04:29: sipSPICreateAndStartRtpTimer:Media Inactivity timer created for call.
Mfactor(from CLI): 5 RTCP bandwidth: 500
RTCP Interval(in ms): 5000
