Hi Lakshman,
Everytime user clicks on a new shop, create a session variable and set it to any value.
userSessionData.setAttribute("NEWSHOP","true");
Now go to history.jsp and just above this piece of code put a validation for the value of this session variable and
if its value matches to "true" than only let the below code to execute.After the validation dont forget to remove this
variable from session.
<isa:iterate id="historyItem" name="<%= UpdateHistoryAction.HISTORY_LIST %>"
type="com.sap.isa.isacore.HistoryItem">
Likewise you can work with organizer frame refresh also.Hope this helps you.
Regards,
Arshi

How to create the data for custom objects in pList

Hi,
I am new in developing on iPhone and I don't know much about this area. I would like to ask a question. I couldn't find the answer on this question in apple documentation but I hope Internet community will help me.
Lets say I have a class called classA. The classA has 2 public properties (or fields):
*int customIndex*;
and
NSString *customTitle;
My view controller class showMeSomething has a property NSArray which holds the objects of type classA. I would like to load the array from the plist resource file. How do I edit the resource file with initial values or how do I know the format of the plist which can be loaded from using mainBundle for my array of custom objects?
Thanks!

Here's some info on working with plists:
http://developer.apple.com/documentation/Cocoa/Conceptual/PropertyLists/Introduc tion/chapter1_section1.html
They can be edited with any text editor. Xcode provides a graphical editor for them - make sure to use the .plist extension so Xcode will recognize it.

How to improve the performance for integrating third party search engine

hi,
I have been working on integrating verity search engine with KM. the performance for retrieving search result totally depend on how many search result returned, for example if there is less than 10 records, it only takes 3 seconds, but if there are 200 records, it takes about 3 minutes, is it normal? anyway to improve it? Thanks!
T.J.

Thilo,
thanks for the response, would you recommend some document for configuring KM cache service, I did change memory cache, and also dynamic web reposity, whatelse out there that I can change? right now, I have one instance(EP6.4 sp11) works well, it returns 200 records from Stellent within 6s. But when I put this KM global service on EP6.0 sp2 (our current system) it takes about 15s. I am not sure is this because of different EP version, or something else. I have tried my best to slim down SOAP component from Stellent. I don't think anything else can be done from that side anymore. before I changed the SOAP, it tooks about 60s. just wonder what else I can do on KM side to improve it performance? Thanks!

How to clear the Google search history

How to set a customized search results template for all users

Hi.
I know the customized search results views are stored in a file called pne_portal.hda that resides on every user's subfolder in data/users/profiles/...
Is there a way to set a customized search results template for all users? If it's impossible, is there a way to modify the Headline view? I'm not able to find the resource or template where this view is.
Thanks in advance.

I wasn't able to understand what was meant by this post. Therefore, I modified the standard template HeadLine View.
Columns for this template are defined in the include slim_search_result_table_header_setup (in std_page.htm).
Here is the modification of the code:
<$if customTemplateId and not (baseTemplateId like customTemplateId)$>
          <$columnsString = utGetValue("customlisttemplates/" & strLower(customTemplateId), "columns")$>
          
     <$else$>

          <$columnsString="dDocName,dDocTitle,dInDate,dDocAuthor"$>

          <$columnsString=columnsString&",xComment"$>
          
     <$endif$>

This is a user to user support forum. We are all iphone users just like you.
You are not addressing Apple here at all.
This is an odd way to ask your fellow iphone users for help. Berating oterh users will not help you.
"it's too fragile"
No it is not. i have never damaged one, nor has anyone I know.
" U loose data when Ur phone is locked"
No you don't. Why do you think this?
"and there is no customer support!!! "
Wrong yet again. Apple has an 800 number and they have many retail stores and they have support articles that you can access using the search bar. Or you can contact them throgh express lane online
"but I will go back with Blackberry "
Please do.
Good ridance

Please tell me.. How to clear the variable value in
session store? I'd like to set it to null. If you have greater
way to do like this, please tell me.
Thank you.

delete single message or delete entire thread?
Single message: open messages, then open the thread, then press and hold on the message that you want to delete.
Entire thread: Open messages, then press and hold on the thread you want to delete.
When you go through text message and you click on button to bring up Roller Top Chain contacts, there is couple choices (groups, contacts, favorites & logs) you can choose. Under logs, how to you delete the information in logs section????? It appears to only go back a few days, but can't find option to erase logs. If you check box it just adds that person to your send to Sushi Chains. I also tried deleting history for phone calls, but its still there. Any help would be great!!!

How to change the icon for print dialog?

Hello,
I have a JTable, and with the print() method, I'm able to bring up the Print dialog and successfully print the contents of the table. Example:
myTable.print( JTable.PrintMode.FIT_WIDTH, myHeaderFormat, myFooterFormat );This works great, but one small detail I'd like to change is the icon in the top-left corner of the dialog. The icon is currently the default Java coffee cup icon, while the rest of my application uses my custom icon. I couldn't find any documentation in the API or tutorials that Java has listed which shows how to change the icon, so I'm not even sure if it's possible (but why shouldn't it be?).
My question is this: Is it possible to change the default icon in the print dialog? Or do I have to either make my own print dialog somehow, or use a third-party print dialog?
Thanks

tjacobs01: Appreciate the assistance (despite your sass). I've already searched the API, tutorials, and this forum. I'm already well aware of the setIconImage() method for JFrame -- after all, that's how I set the icon for my other frames as I previously mentioned. However, I want to set the icon for the print dialog called from the print() method of JTable.
How would I use setIconImage() for the print() method of JTable? The print() method returns a boolean value, not a JFrame, so I'm just not sure how to implement what you're saying.
Thanks
