• How to implement a custom button without the standard template.fmb lov?

  Hello
  
  I'm developing an application using oracle's 10g. I can't use the standard template.fmb because my application is not running in ebs. There comes the problem: I want to implement the function of button lov as the model, such as:
  1. when the text element gets the focus, display button lov.
  2. when the lost text element the focus, the lov button disappear.
  3. when the reels of the scroll bar, the position of the button lov adjust accordingly.
  4. There is only one lov in a form button and the button lov appeared dynamic.
  
  I found that it is very complex for that.
  can anyone help?

  Try changing the following parameter to true

  app.ui.lovButtons=false

• Aggregator customized to calculate the standard deviation

  Hello
  This is probably already available or easy to implement, but I find it difficult to find samples for writing a custom aggregation and ParallelAwareAggregator.
  
  I'm figuring the difference type of a variable in my item being cached in a real-time system. I want to aggregate the result sum [(X-X') ^ 2] where I spend X' (average) of the client. Can someone help me with an example?
  
  Thank you
  Sairam

  Hi Sairam,

  in fact, you probably have better use the single-pass approach to calculate the standard deviation, as the average of the values may change before you calculate the number of entries and the average gap.

  You can use the following formula to calculate the standard deviation in one pass: sqrt (N * sum (sqr (Xi)) - sqr (sum (Xi))) / N, where the sqr function is the square of a value, the square root function is the square root of the value, N is the number of entries and Xi is the value to calculate the gap type from the entry of the i - th.

  You can do something like this:

  public static class StdDeviation implements ParallelAwareAggregator {
  
    public static class PartialResult implements Serializable {
  
        private long numberOfElements;
        private BigDecimal sum;
        private BigDecimal sumSquare;
  
        public PartialResult(long numberOfElements, BigDecimal sum, BigDecimal sumSquare) {
            this.numberOfElements = numberOfElements;
            this.sum = sum;
            this.sumSquare = sumSquare;
        }
    }
  
    public static class ParallelPart extends StdDeviation implements EntryAggregator {
  
       private ParallelPart(ValueExtractor extractor) {
          super(extractor);
       }
    }
  
    private ValueExtractor extractor;
  
    private transient boolean notParallel;
  
    public StdDeviation(ValueExtractor extractor) {
      this.extractor = extractor;
      this.notParallel = true;
    }
  
    public Object aggregate(Set entries) {
       ValueExtractor extractor = this.extractor;
       BigDecimal sum = 0;
       BigDecimal sumSquare = 0;
       long num = 0;
       for (InvocableMap.Entry entry : (Set) partialResults) {
          sum = sum.add(partialResult.sum);
          sumSquare = sumSquare.add(partialResult.sumSquare);
          num += partialResult.numberOfElements;
       }
  
       return calculateStdDeviation(num, sum, sumSquare);
    }
  
    public EntryAggregator getParallelAggregator() {
  
       // you could return this, instead of ParallelPart
       //
       // return this;
  
       return new ParallelPart(extractor);
    }
  
    private static Number calculateStdDeviation(long num, BigDecimal sum, BigDecimal sumSquare) {
       BigDecimal partRes = sumSquare.multiply(new BigDecimal(num)).subtract(sum.multiply(sum));
  
       // you can replace the square rooting of a double value with a proper implementation of square root for BigDecimals,
       // which I omitted for the sake of brevity, and then you can do BigDecimal division (make sure you provide a MathContext)
       return Math.sqrt(partRes.doubleValue())/num;
    }
  
    public static Number execute(NamedCache cache, ValueExtractor extractor) {
       return (Number) cache.aggregateAll(AlwaysFilter.INSTANCE, new StdDeviation(extractor));
    }
  }
  

  There is actually no reason for the class ParallelPart to exist. I put it here to illustrate that there can be a different aggregator instance to the ParallelAware aggregator optimized to run on the side of the storage, but you could just "this" return of the getParallelAggregator() method, it wouldn't make a difference for this implementation of the aggregator.

  You can replace the rooting square a double value with a good implementation of the square root of BigDecimals, which I omitted for brevity, and then you can make division BigDecimal (make sure that you provide a MathContext)

  I also omitted the ExternalizableLite and PortableObject implementations (and necessary parameterless constructors) for brevity of the ParallelPart and PartialResult classes.

  In addition, you may need some mojo if you want to use a PofExtractor instead of a regular Value Extractor to avoid the deserialization of the cached value.

  You can perform the aggregation with the execute method, passing the cache altogether on the Extractor which extracts the value as a BigDecimal value cached.

  Version of the class 51 is Java 7, this suggests that you have compiled your classes in the Java JDK 7, but try to load them into an earlier version of Java (I guess Java 6 since this is the first version of Java that runs under Apache Tomcat 7).

  You can specify the JDK compiler to create classes that target Java 6, which should then work - see "javac - Java programming language compiler.

• need a script to custom calculation to calculate the standard deviation

  need a calculation script customized to calculate the standard deviation of 8 rows, it is a form .pdf variable data entry points will be users using this model as a form.

  I can get the average of simple calculation, but struggling with the script for the standard deviation. Any help would be appreciated.

  Header 1	Header 2	Header 3	Header 4	Header 5	Heading 6	Heading 7	8 header	Header 9	Header 11
  sample1Row1	sample2Row1	sample3Row1	sample4Row1	sample5Row1	sample6Row1	sample7Row1	sample8Row1	Average	stdDeviation

  If the formula is not:

  StdDev = sqrt (sum (sampleXRow1 - average) ^ 2 / (n-1))

  But:

  StdDev = sqrt (sum ((sampleXRow1-average) ^ 2) / (n-1))

  If the code should be something like this:

  var avg = Number(this.getField("AverageRow1").valueAsString);
  var sum = 0;
  var n = 0;
  for (var i=1; i<=8; i++) {
      var v = this.getField("sample"+i+"Row1").valueAsString;
      if (v!="") {
          sum+=Math.pow((Number(v)-avg),2);

• Customized using AID the deployment of ABC with XPATH error

  Hi all
  
  I use a function custom xpath as described below in the ABC BPEL provider.

  < variable = 'element VariableName' = 'main' / >

  I dropped the class in $SOA_HOME/soa/modules/oracle.soa.ext_11.1.1/classes, and it always seems that the HELP is not able to locate the class. I'm fall classes in the right location, or is this something else that is missing? Pointers are appreciated.
  
  Thank you
  Anish.

  Anish,
  This comes as a result of compilation of SOA tools do not include $SOA_HOME/soa/modules/oracle.soa.ext_11.1.1 in the class path, such as $SOA_HOME/bin/ant-sca-compile.xml which is used in turn by AID for the development of composite materials.

  You can work around this by adding classes/libraries custom $SOA_HOME/bin/ant-sca-compile.xml in the classpath. Add the following entry in the section "":
  

  With this Ant-sca - compiles .xml and so also HELP will be aware of your function custom xpath and the compile error should disappear.

• Problem call query in custom tag

  I use this code to call a custom tag called broadcast.cfm
  
  < cf_broadcast query = orgID "fe" = "4" >
  
  The fe application is a file included on my website and is available to the page, that I call the custom tag.
  
  In the custom tag, I am referencing the query as:
  
  < cfloop query = "#attributes.query #" >
  
  but I get this error message:
  "The value of the query of the attribute, which is currently 'fe', is not valid."
  
  I must be missing something really simple here, but cannot understand what he.

  It's a scope issue. The query is defined in the calling page. To access by name, within the custom tag, use the 'calling '.

• User error needs help correction-&gt; repeatable Tag on the attribute custom section

  Okay, I v.6111.  Today, I put manually the tag supplier_eq_create on all the existing attributes in our sections for suppliers can add them when we send the EQS. Unfortuately, I accidentally clicked on the reproducible tag instead of Supplier_EQ_Create in some cases in our environment Export/setting in scene.  When I try to remove its repeatable label, I get the error that says "reproducible State of the line can be changed after the outbreak of the line"... we did not really use the reproducible feature of the tag.  I need to know how I can remove this tag with the attributes of active due to human error before importing it to PROD.  The forum can help me?

  Best, Beckie

  Hi Beckie,

  As long as you are sure that nobody use it you can remove this tag with a database script.

  As with all scripts, make sure that you back up your data.

  With the following script, you can find the lines that contain the reproducible tag of a particular section model

  select rowTemplate.* from eaSectionDynamicTagJoins rowTTagjoin
  inner join commonEARowTemplate rowTemplate on rowTemplate.pkid = rowTTagjoin.fkEAS
  inner join commonLookups tag on tag.pkid = rowTTagjoin.fkTag
  inner join commonEASectionTemplate sectionTemplate on sectionTemplate.pkid = rowTemplate.fkSectionTemplate
  where tag.Name = 'Repeatable' and langID = 0 and Category = 'EASRowDynamicTag'
  and sectionTemplate.id = '';
  

  Tags are related to patterns of row of section customized using the eaSectionDynamicTagJoins table.

  You can remove the tag of a specific line by using the following script

  delete from eaSectionDynamicTagJoins
  where fkEAS = '';
  

  I hope this helps. Let me know if you have any questions,

• Registration error of the standard warranty - how to change

  Hello

  I have a standard warranty for my laptop that I bought in the 16th of this month. I went to the Web page of warranty: www.toshiba-europe.com/registration, but I made a mistake. Instead of saving it to the 'standard' guarantee, I registrate in "extended warranty"... and then I relizes my mistake when he refused to accept the agreement 'number', so I skiped the operation.

  I went back to register in the 'standard' warranty, and when I finished to fill in all the information, I + click + 'save' but then they said "this nootbok is already registered"... and the operation was not + * finished * +.

  So I ask how I can fix this "error"... and save my standard warranty... ???

  Please, if anyone can help me I would be VERY grateful for your responses...

  =)

  I would call Toshiba and ask them to look into the issue. This looks like a bug with the website.

Im not exactly smart pc and am afraid of doing something wrong then Im left to do very limited things, any help would be appreciated

  Hello mikegrimesWQ,

  Because it looks like you have reinstalled Windows XP, what happens when you turn on your computer?  Windows loads correctly and allow you to connect with success?  Have you completed all the updates of Windows since the relocation?  Do you get errors at any time?

  What version of Windows XP you are using and which service pack is currently installed?  I would say confirming all your drivers are recognized and updated.

  How to download updates that include drivers and hotfixes from the Windows Update Catalog

  Please let us know status.

  Thank you

• Error 2738 - could not access VBScript Runtime for custom action during the INSTALLATION of broadband dongle by distribution VODAFONE K3565 rev2. ON WINDOWS 7 PREMIUM

  Whenever I try to install a dongle broadband PAYG Vodafone K3565 rev2, I get an error message; -error 2738 - could not access VBScript Runtime for custom action. I am running Windows 7 Home Premium on a Samsung R522 again.
  I found that I got the same error message when I tried to install INCREDIMAIL on the same computer laptop.

  On the vodafone website, I found a resolution the resolution I found was;

  1. run command prompt as administrator
  1.1 Start Menu-> all programs-> Accessories
  1.2 right-click on command prompt and select run as administrator of
  
  2. If you are using the 32-bit version of Windows:
  Type cd %windir%\system32 in the command prompt and press ENTER.

  If you are using the 64 bit version of Windows:
  Type cd %windir%\syswow64 in the command prompt and press ENTER.

  3. type regsvr32 vbscript.dll in the command prompt, and then press ENTER.
  

  When I tried this, I got a message that this had been done but I tried to install the programs and even once, they both failed and I got the same error as before.
  
  Can anyone help?

  Well... It has been a week. I know too much now.

  ATTENTION: This field is very complicated AND there are too many incorrect analyses out there.

  The problem for me is (FOCUSED) that the current user HK had entires THAT SHOULDN'T BE!

  The computer settings are found under the Local Machine of HK. HKLM must be correct.

  Procedure: REMOVE all entries in HKCU. Correct path the InprocServer32 value.

  My specific (2738) error occurred trying to find "vbscript.dll" (aka "\{B54F3741-5B07-11cf-A4B0-00AA004A55E8"})

  Some antivirus software redirects requests for certain things by herself (aka 'diversion'). If the

  InprocServer32 is EMPTY (in HKCU - for me). All of the solution has been to remove the HKCU entries.

  Another little attention is: (for example) vbscript.dll has several references (app, authorization, RegExp)

  so be on the lookout for the 2 and 3, as well.

  \{B54F3741-5B07-11CF-A4B0-00AA004A55E8}

  \{B54F3742-5B07-11CF-A4B0-00AA004A55E8}

  \{B54F3743-5B07-11CF-A4B0-00AA004A55E8}

  I removed the entries in HKCU. Run the error code again. (Mine = .msi)

  This information is redundant. Gokul T response (upstairs) was correct. It does not sink into my head when I read it. But this thread was open the door to the solution for me.

  Thank you...
