Different behavior when URL Parameter clientDebug is set

Hi experts
I'm facing a strange behavior in my WebDynpro application.
Whenever I launch it with the URL parameter sap-wd-clientDebug set to X the interactiveForm element on one of my views works flawlessly (i.e. the assigned context nodes on my view get updated on each roundtrip and changes in the context are reflected in the interactiveForm). When sap-wd-clientDebug is not set however the interactiveForm still communicates with the WD (a breakpoint in a dummy OnSubmit action is triggered correctly when the submit button on the interactiveForm is pressed) but contex changes are no longer reflected in the interactiveForm. Only after navigating back and forth between my views does the interactiveForm get updated.
Any hints or ideas on how to solve this issue would be great.

Only the attributes dataSource and templateSource of the interactiveForm element are set.

Different behavior when running in Eclipse and on Tomcat

I am having a problem because the program that I wrote, tested, and work fine on Eclipse doesn't have the same behavior when I convert it to a Web Service and called by a client.
I have not this strange behavior. See this code:
NamedNodeMap attrs = node.getAttributes();
System.out.println(attrs.getNamedItem("performance"));When I run it on exist I got something like this:
org.apache.crimson.tree.AttributeNode1@11bed71which should be correct since attrs.getNamedItem() return a Node.
But! When I run it as a web service on Axis hosted on Tomcat I got
performance="3758.0"???!!!
Also, when I do something like
System.out.println(node)In Eclipse I got the whole XML file like this:

[root: null]I'm confused. I think it might be because of the different version of the library between eclipse environment and axis environment. But the problem is, I can't figure out what JAR should I change. Can you give me a clue??

DOM doesn't specify what the toString() method of Node etc. should return. So each implementation of DOM chooses something that seems reasonable to the implementers. If this isn't suitable for you then don't use the toString() method. (That's what System.out.println calls when you pass it an Object, in case you didn't know.)

Setting different reporting services url via IReportServerConnection

y report. I have problem using more than one reporting services urls via IReportServerConnection.
Specifically, I need to display report from different report services url on different page via IReportServerConnection. Each page uses report viewer web forms control. The problem is that how to assign different report services url for different page.
Below is the settings related to IReportServerConnection:
<appSettings>
<add key="ReportViewerServerConnection" value="ReportServer.ReportServerConnection" />
</appSettings>
public class ReportServerConnection : IReportServerConnection {
public Uri ReportServerUrl { get; set;}
Below shows report viewer control that is used on different page that needs different reporting services urls:
<rsweb:ReportViewer ID="reportViewer" runat="server"
ProcessingMode="Remote">
<ServerReport />
</rsweb:ReportViewer>
Thanks in advance.

How to get the URL parameter value when navigating from JSP Page to portal

Hi All,
I have web Dynpro application with one button, while clicking that button It will navigate to JSP page as external window. In the JSP page I have a input field and Button.
In the JSP page input field I will enter some values and press submit button, it will navigate to Portal page by passing some URL parameter with values.
Once user entering to portal by default WD page displayed, the same WD page I try to get the URL Parameter which I have passed from JSP page, but I am not able to get the URL parameter value.
If same application running in without portal, I can able to get the URL parameter values. I am getting the URL parameter by interface view default inbound plug parameter.
How do we resolve this problem?

How to catch URL parameter from Portal URL in Web Dynpro iView

Hi All,
I have a web dynpro application running as a portal iView successfully. Now the client wants to make it internationalized with 7 languages. Currently they access the portal - and via role assignment they get to the portal tab with the wd iView. Now they want to send a parameter for the language key with the portal URL. So when they are typing in http://myportal.mydomain.com now they want to type in http://myportal.mydomain.com?sap-locale=de or so. My question is how can I catch this parameter in the WD application when it is running inside a portal iView? Is it at all possible?
I have written a very small application which is trying to catch a URL parameter named PARAM. The code I have written is the default one as below:
String paramValue = WDWebContextAdapter.getWebContextAdapter().getRequestParameter("PARAM");
When I run the application standalone and add the PARAM=something in last of the URL I can catch it. But when I create an iView and while previewing it I add the same PARAM value it is coming as null all the time. Same when I add this iView to a role and show it via role assignment in protal. Please help to let me know how to achieve this. I think if I can read the parameter value from Portal URL in the WD iView - then I can set it as the default locale of the application and then show language specific file to achieve internationalization.
Your urgent help will be highly appreciated.
Warm Regards,
Shubho

Hi Shubhadip
Even if you get the parameters, how do you internationalize your application? Are you not following the standard way as described in the following link. In this case you never need to capture any such parameter. This is done by the WD runtime automatically .
<a href="http://help.sap.com/saphelp_erp2005/helpdata/en/f4/d95664da179b4db731e21c2e470b72/frameset.htm">Internationalization of WD projects</a>
You can retrieve application parameters specified at the creation of iview by "adding parameters(with the same name as in iview application parameters) to the default plug of the Component Interface View of the WD application". "onDefaultPlug" method of the interface view controller you get these values as parameters, which you can save in the context node of component controller for later use.This is guaranteed to work.
But again this is not what you want exactly. You want the user to specify the value at runtime. If you have just 7 languages, you can create 7 set of iviews with different application parameter value indicating language key, and assign to 7 different set of roles, each representing one set of users with common language.
I hope you find a solution.

SQL Query produces different results when inserting into a table

I have an SQL query which produces different results when run as a simple query to when it is run as an INSERT INTO table SELECT ...
The query is:
SELECT   mhldr.account_number
,        NVL(MAX(DECODE(ap.party_sysid, mhldr.party_sysid,ap.empcat_code,NULL)),'UNKNWN') main_borrower_status

FROM     app_parties ap
SELECT   accsta.account_number
,        actply.party_sysid
,        RANK() OVER (PARTITION BY actply.table_sysid, actply.loanac_latype_code ORDER BY start_date, SYSID) ranking
FROM     activity_players actply
,        account_status accsta
WHERE    1 = 1
AND      actply.table_id (+) = 'ACCGRP'
AND      actply.acttyp_code (+) = 'MHLDRM'
AND      NVL(actply.loanac_latype_code (+),TO_NUMBER(SUBSTR(accsta.account_number,9,2))) = TO_NUMBER(SUBSTR(accsta.account_number,9,2))
AND      actply.table_sysid (+) = TO_NUMBER(SUBSTR(accsta.account_number,1,8))
) mhldr
WHERE    1 = 1
AND      ap.lenapp_account_number (+) = TO_NUMBER(SUBSTR(mhldr.account_number,1,8))
GROUP BY mhldr.account_number;      The INSERT INTO code:
TRUNCATE TABLE applicant_summary;
INSERT /*+ APPEND */
INTO     applicant_summary
( account_number
, main_borrower_status
, num_apps
SELECT   mhldr.account_number
,        NVL(MAX(DECODE(ap.party_sysid, mhldr.party_sysid,ap.empcat_code,NULL)),'UNKNWN') main_borrower_status
,        COUNT(1) num_apps
FROM     app_parties ap
SELECT   accsta.account_number
,        actply.party_sysid
,        RANK() OVER (PARTITION BY actply.table_sysid, actply.loanac_latype_code ORDER BY start_date, SYSID) ranking
FROM     activity_players actply
,        account_status accsta
WHERE    1 = 1
AND      actply.table_id (+) = 'ACCGRP'

) mhldr
WHERE    1 = 1
AND      ap.lenapp_account_number (+) = TO_NUMBER(SUBSTR(mhldr.account_number,1,8))
GROUP BY mhldr.account_number;      When run as a query, this code consistently returns 2 for the num_apps field (for a certain group of accounts), but when run as an INSERT INTO command, the num_apps field is logged as 1. I have secured the tables used within the query to ensure that nothing is changing the data in the underlying tables.
If I run the query as a cursor for loop with an insert into the applicant_summary table within the loop, I get the same results in the table as I get when I run as a stand alone query.
I would appreciate any suggestions for what could be causing this odd behaviour.
Cheers,
Steve

Yes, using COUNT(*) gives the same result as COUNT(1).
I have found another example of this kind of behaviour:
Running the following INSERT statements produce different values for the total_amount_invested and num_records fields. It appears that adding the additional aggregation (MAX(amount_invested)) is causing problems with the other aggregated values.
Again, I have ensured that the source data and destination tables are not being accessed / changed by any other processes or users. Is this potentially a bug in Oracle?Just as a side note, these are not INSERT statements but CTAS statements.
The only non-bug explanation for this behaviour would be a potential query rewrite happening only under particular circumstances (but not always) in the lower integrity modes "trusted" or "stale_tolerated". So if you're not aware of any corresponding materialized views, your QUERY_REWRITE_INTEGRITY parameter is set to the default of "enforced" and your explain plan doesn't show any "MAT_VIEW REWRITE ACCESS" lines, I would consider this as a bug.
Since you're running on 10.2.0.2 it's not unlikely that you hit one of the various "wrong result" bugs that exist(ed) in Oracle. I'm aware of a particular one I've hit in 10.2.0.2 when performing a parallel NESTED LOOP ANTI operation which returned wrong results, but only in parallel execution. Serial execution was showing the correct results.
If you're performing parallel ddl/dml/query operations, try to do the same in serial execution to check if it is related to the parallel feature.
You could also test if omitting the "APPEND" hint changes anything but still these are just workarounds for a buggy behaviour.
I suggest to consider installing the latest patch set 10.2.0.4 but this requires thorough testing because there were (more or less) subtle changes/bugs introduced with [10.2.0.3|http://oracle-randolf.blogspot.com/2008/02/nasty-bug-introduced-with-patch-set.html] and [10.2.0.4|http://oracle-randolf.blogspot.com/2008/04/overview-of-new-and-changed-features-in.html].
You could also open a SR with Oracle and clarify if there is already a one-off patch available for your 10.2.0.2 platform release. If not it's quite unlikely that you are going to get a backport for 10.2.0.2.

Webdynpro appln Url parameter "sap-wd-client= XML client "

Hi all,
I am a beginner in Webdynpro application development.
I have a query on the usuage of Url parameter "sap-wd-client=XmlClient" in webdynpro application.
When i set the Application parameter property of webdynpro iview in portal as "sap-wd-client=XmlClient", i am getting the content of webdynpro appln in XML format. What is the use of this XML format.
Can we use this webdynpro appln in XML format in any other portal say Weblogic portal and produce an UI in that portal.
Let me know the use of this XML format.
Pls give me some exposure on this.
Thanks & Regards,
Siva

Hi sivakumar,
It is used for supplying data to another kind of client. You can download a trial version of it somewhere on SDN.

ESS Benefits Generic Enrollment - Different behavior backend v/s portal

We are using the ESS Benefits generic enrollment service for enrollment kicking off the adjustment reasons on IT 0378.
Here is the configuration set up, trying to simplify to explain the matter. We are on ECC 6.0 with EHP2.
1. Configured one plan type in savings category.
2. Within this plan type, configured 2 plans.
3. Configured all other related configuration to set up the 2 plans.
4. Configured the adjustment reason and the appropriate plan type created in step 2.
5. Created the required adjustment reason on 378.
In HRBEN0001 transaction via backendwe can see the 2 plans configured within the plan type.
But when Trying to enroll from ESS - only one plan can be seen for that plan type, the other plan is not shown at all.
OK - eventually, debugged and found this piece of code in FM HR_BEN_ESS_FILL_SELECTION_DISP. The 2 different plans are there until this piece of code takes one of them Off...
CODE -
3.) Reduce entries to one entry per type and period
delete adjacent duplicates from selection_display_gt
    comparing pernr
              barea
              bpcat
              pltyp
              begda
              sprps.
CODE -
This FM is called only for ESS application and not for backed program.
What we do not understand is why is it behaving differntly on backend v/s portal.
Any information or experience with this form any one of you will be highly appreciated.
Thanks.

Siddharth,
Thanks for your reply. Yes ESS has its own FMs. The UI, user exits, BADIs etc are different for backend v/s front end.
What we are not clear with, is the different behavior in core functionality -- i.e. When the adjustment reason is processed from the backend using HRBEN0001 - The 2 plans within the Plan Type are available for elections. BUT the same adjustment reason for the same penr when processed from ESS - there is just one plan available for elections.
It's clear from the code, that it is deleting one plan and this code is within the FM which is called only from ESS. But we are still not sure why it should behave differently i.e. 2 plans via backend v/s one plan via ESS.
Wanted to see if anyone can share any information if they have a similar benefits set up .. 2 plans within one plan type FOR savings plan category and then having a adjustment reason set up.
Regards.

Different behavior of movewindow with different windows is (xp or windows 7)

we have a windows wpf stand alone application which must be integrated within a windows form 2.0 stand alone application. given to the particular implementation of the windows form application we decided to use a light integration trying to change the parent
handle of the wpf main window setting as parent the handle of a windows of the windows form 2.0 application.
in order to reposition the wpf windows on top of the parent windows form window, we have a thread which keeps doing two operations: (1) invoke getwindowsrect on the parent windows form windows to get the parent absolute position and (2) invoke movewindow
on the wpf main window handle to reposition the window.
when we move the windows form window, the wpf windows follows the parent remaining in the correct position. we tested this solution with windows xp, windows 7, windows 8 in our office. when we went to the customer to complete the installation, both on a
windows xp and on a windows 7 the behavior was different. the size of the wpf window was much bigger than the size of the windows form parent window. back in office we found the same strange behavior in windows xp wirtual machine. in order to fix the problem
(at least partially) we had to change the operation sequence within our code as follows in the monitoring thread: (0) get parent windows position with getwindowrect (1) set the parent of the wpf main window to (null) 0 invoking setparent, (2) invoke the movewindow,
(3) re set the parent handler of the wpf main window to the handler of the windows form window.
with last solution it works but clearly there are more flikering when the window is moving or resizing respect to initial implementation.
any idea about this different behavior of movewindow function? any suggestion?
thanks

Problem passing Session variable as URL parameter?

Hi,
I am trying to create a multiple page entry form using
coldfusion session. But I am having some problem when passing the
session variable to url parameter. For test purpose I have created
the following code:
<cfif Not IsDefined("SESSION.AE")>

<cfset SESSION.AE = StructNew()>

<cfset SESSION.AE.StepNum = 1>
</cfif>
<cfif IsDefined("Form.GoBack")>
<cfset SESSION.AE.StepNum = #url.StepNum# - 1>
<cfelseif IsDefined("Form.Next")>
<cfset SESSION.AE.StepNum = #url.StepNum# + 1>
</cfif>
<html>

<input type="submit" name="GoBack" value="Back">
<input type="submit" name="Next" value="Next">
</form>
</body>
</html>
When run it I get the following error:
The value "" cannot be converted to a number
The error occurred in C:\CFusionMX\wwwroot\AE\try.cfm: line

12 : 
13 : </cfif>
I couldn't figure out where is the problem. Any help is
really appreciated.
Thanks in advance.

You are mixing up your gets and posts aren't you?
You have your form method set to post which creates form
variables not
url variables. So when you try to use the url variable to set
your
session it does not exist.
Change your SESSION.AE.StepNum = #url.StepNum# to
Session.AE.StepNum =
form.StepNum, note there is no need for the #'s.
OR
change your form method="post" to form method="get"

Different behavior with decimal data on same version of CF

I have a linux/apache/mysql/CF MX 7 Enterprise server. I insert decimal data using the cfqueryparam that looks like
<cfqueryparam value="#BudgetSet.BUD_SET_DETAIL_COST_PER#" CFSQLType="CF_SQL_DECIMAL">.
No problems the decimal data does not get rounded, 123.45 inserts as 123.45.
I'm building applications for my neighborhood association, so I'm having godaddy.com host the web site with CF and MySQL.
Like a good developer, I took code from my CF server, moved some of the more useful programs to the godaddy.com, set up the database and started testing some apps. Now any decimal data inserted gets rounded using the same cfqueryparam syntax from my CF server (like above). The decimal data on the godaaddy.com inserts as 123.00, when I'm trying to insert 123.45, of course if I insert 123.99 I get 124.00, rounding. So I called godaddy.com and of course I get the standard technical answer "its your code". So off to testing I go. Only to determine, by not using the cfqueryparam, I could stop the rounding, more testing I determined that I need to use
<cfqueryparam value="#BudgetSet.BUD_SET_DETAIL_COST_PER#" CFSQLType="CF_SQL_MONEY"> or
<cfqueryparam value="#BudgetSet.BUD_SET_DETAIL_COST_PER#" CFSQLType="CF_SQL_DECIMAL" scale="2">. The version of CF @ godaddy.com is also MX 7 Enterprise. Finally the question, what in configuration could cause such different behavior ?
Thanks for reading my short novel.

The database drivers determine how the cfqueryparam values are
interpreted (behind the scenes ColdFusion generates a prepared
statement using the driver interface and sets the values using
standard JDBC calls). Unfortunately, like you found out, not all
drivers are created equal and have slightly different behavior or
defaults.
I would check and compare the driver versions.

Different behavior for index

Hi.
I have the table inl_allocations with following index:
CREATE INDEX inl_allocations_n1 ON inl_allocations
( ship_header_id                  ASC,
    adjustment_num                  ASC,
    ship_line_id                    ASC )
When running query below, we have different behaviors for indexes in different DB:
SELECT *
FROM INL_ALLOCATIONS CA, INL_SHIP_LINES_ALL CC
WHERE CC.SHIP_LINE_ID = CA.SHIP_LINE_ID
AND CC.SHIP_HEADER_ID = CA.SHIP_HEADER_ID
1- For DB 1 (11.2.0.1.0) the explain plan for query:
                (3) INDEX INDEX FULL SCAN INL.INL_ALLOCATIONS_N1 [Analyzed]
                    Est. Rows: 33 Cost: 1
2- For DB2 (11.2.0.3.0) the explain plan for query does not use the index INL_ALLOCATIONS_N1, and we have a FULL in table.
           (3) TABLE TABLE ACCESS FULL INL.INL_ALLOCATIONS [Analyzed]
           (3)   Blocks: 13 Est. Rows: 167 of 269 Cost: 5
We would like to know the reason why there are differences between both environments.
Thanks and Regards.

many years ago Oracle used to optimize queries with a set of rules that ranked the potential access paths and finally chosed the possible operation with the highest rank. So for two systems with the same DDL Oracle would have generated the same plan. This was the rule based optimizer (RBO) and its shady ghost still dwells somewhere deep in the Oracle code. Since at least Oracle 8i (> 10 years ago) the standard optimization engine is the cost based optimizer (CBO) which uses statistics to generate execution plans: and if the data of your systems is different (or even if the data is identic but its physical order is different and changes the index clustering factor) the CBO can and will generate different plans and use or not use existing indexes.

RDCMan different behavior for different machines

I'm using Remote Desktop Connection Manager, which has been very useful since I have to remote into so many different machines.
I am curious though and this is more of a question than a problem, but I notice different behavior remoting into different systems.
On some servers, I get this popup when I connect:
On other servers, I get brought to this screen to enter my password:
I've checked the group policy settings, registry settings, made sure I didn't have any saved credentials, makes no difference.
Any idea why?

RDP Session Setting:
Console Session Settings:
Hi,
As per my research, that is the default behavior and it correlates for 2 different scenario “Console and RDP”. When you are performing “Console” of server then it will provide you the direct screen of server to login. But when you want to take RDP
then it will ask you as “Windows Security” login prompt.
Please check my words on your screenshots
Hope it helps!
Thanks.

Reading URL Parameter

Dear Experts
I have created a webdynpro ivew, and added a Quick link to it and added to the workset. So that I can acccess the ivews form URL. I need to pass the URL paramenter also
like
http://<Server Name>:<portNumber>/irj/portal/Quick link?param1=Value, Now I need to read the param1 value in my Webdynpro code.
When i set the value in Application parameter I was able to get the value using the following code
path=WDProtocolAdapter.getProtocolAdapter().getRequestObject().getParameter("path");
My Question in how to get the value which is given in URL parameter
Regards
Noel

Hi
I think the code that you mentioned should works. I observe one thing that in getParameter you mentioned path as an argument. You need to mention the application parameter name.
Also, if you run the webdynpro application standalone you will not get its iView application parameter. You should only run the iView in portal or in preview mode to get the desired value.
Following code can help you in listing down all the application parameters that a webdynpro iview can contain. If you mentioned your parameter it will display the same too:
          Enumeration enum =
               WDProtocolAdapter
                    .getProtocolAdapter()
                    .getRequestObject()
                    .getParameterNames();
          for (Enumeration e = enum; e.hasMoreElements();) {
               wdComponentAPI.getMessageManager().reportSuccess(
                    "iView Params::" + e.nextElement());
Coming back to your problem, suppose you have application parameter set as ivuParam then you can get its value as
          String ivuParam =
               WDProtocolAdapter
                    .getProtocolAdapter()
                    .getRequestObject()
                    .getParameter(
                    "ivuParam");
Hope this helps.

Odd behavior when using custom Composite/CompositeContext and antialiasing

Hi,
I created a custom Composite/CompositeContext class and when I use it with antialiasing it causes a black bar to appear. I seems it has nothing to do with the compose() code but just that fact that I set my own Composite object. The submitted code will show you what I mean. There are 3 check boxes 1) allows to use the custom Composite object, 2) allows to ignore the compose() code in the CompositeContext and 3) toggles the antialiasing flag in the rendering hints. When the antialiasing flag is set and the Composite object is used the bar appears regardless of if the compose() method is executed or not. If the Composite object is not used the bar goes away.
The Composite/CompositeContext class performs clipping and gradient paint using a Ellipse2D.Float instance.
a) When the Composite is not used the code does a rectangular fill.
b) When the Composite is used it should clip the rectangular fill to only the inside of a circle and do a gradient merge of background color and current color.
c) If the compose() method is ignored then only the background is painted.
d) When antialiasing is turned on the black bar appears, i) if you ignore the compose() method it remains, ii) if you do not use the Composite object the bar disappears (???)
NOTE: the compose method's code is only for illustration purposes, I know that AlphaComposite, clipping and/or Gradient paint can be used to do what the example does. What I am trying to find out is why the fact of simply using my Composite object with antialiasing will cause the odd behavior. Been trying to figure it out but haven't, any help is appreciated.
Thx.

I got a better version to work as expected. Though there will probably be issues with the transformation to display coordinates as mentioned before. At least figured out some of the kinks of using a custom Composite/CompositeContext object.
