• NULL values for some elements of the XML reading tree

  I am confirming that I interpret correctly all the elements of a custom data XML structure defined by my application (the schema is completely under my control).  Some of the elements in my XML tree are read as NULL values, even if similar items are readind as expected.  I have checked some obvious things like misspelling the names of keys, but have not yet find the problem.  Anyone who has debugged similar questions - what else could cause this?

  Example XML:

  
      1.0.0.0
      1000
      MyAppsName
      
          
              1000
              userDefined
              StructName
          
      
  
  

  And extracted C++ w/comments at the end of each line about what I see (DataManager is my class of CRUD operations):

  In DataManager.hpp:

  QVariant mCustomDataStructsTopLevel;
  QVariantMap mCustomDataStructsTopLevelMap;
  

  In DataManager.cpp:

  mCustomDataStructsTopLevel = mXda.load(Utils::dataFilePath(customDataStructsFileName));  // XmlDataAccess; verified loading w/no errors
  mCustomDataStructsTopLevelMap = mCustomDataStructsTopLevel.toMap();
  
  qDebug() << "appName element value: " << mCustomDataStructsTopLevelMap["appName"]; // Outputs "MyAppsName" as expected
  qDebug() << "lastId element value: " << mCustomDataStructsTopLevelMap["lastId"]; // Outputs null (specifically: QVariant(, ) ) - this is NOT expected
  qDebug() << "appVersion element value: " << mCustomDataStructsTopLevelMap["appVersion"]; // Outputs null (specifically: QVariant(QString, "") )  - this is NOT expected
  

  OK, I got the feeling (and actually hoped) it was a silly mistake of face-palm on my part (compared to a problem of BB10 who had little chance of getting fixed).

  The problem is that I copy the structure of custom data from Starter to my Active dir to my data directory to first install but do not crush him on subsequent launches, as the copy in the data directory is what the user changes and relies on.  I was not a delete and reinstall on each of my iterations, so I wasn't really loading the modified versions of my XML I wanted--just, I was getting a day old stale version which was actually for the items I didn't expect NULL values for nulls.  DOH!

• PersistentStore.getPersistentObject returns the null value?

  I use a random key to retrieve a shape of the object PersistentStore

  persist is PersistentStore.getPersistentObject (KEY);.

  Works fine on the Simulator (OS 5), when I take the code signed to the device (BB OS 5.0 Bold 8900)

  For some reason, it returns null, without exception. Thereafter any API I inoke on PersistentStore / persist returns null without exception persist even when the null value.

  I don't know if it's one thing to eclipse debugger, but even if the debugger shows that objects are null. Controls null applied in the code seems to fail, what does code see these objects as non-null. Pheww! How is it possible.

  In this code still shows up as null, then safetyTable and orderedkeys. However, the value null check in the failure code.

  At a later stage in the code, when I try to access orderedkeys are null again! Are struggling with this problem for two days, all the pointers would be very comfortable.

                      persist = PersistentStore.getPersistentObject( KEY );
                      persistOrderedKeys = PersistentStore.getPersistentObject(KEY_ORDERED_KEYS);
                      safetyTable = (Hashtable)persist.getContents();
                      orderedKeys = (Vector)persistOrderedKeys.getContents();
                      if (safetyTable == null)
                      {
                          safetyTable = new Hashtable();
  
                          persist.setContents(safetyTable);
                          persist.commit();
                      }
  
                      if (orderedKeys==null)
                      {
                          orderedKeys=new Vector();
  
                          if (safetyTable.size()>0)
                          {
                              Enumeration addressKeys = safetyTable.keys();
                              while(addressKeys.hasMoreElements())
                              {
                                  orderedKeys.addElement((String)addressKeys.nextElement());
                              }
                          }
                          persistOrderedKeys.setContents(orderedKeys);

• How to implement 'Null value replace' inside a RTF

  Hello

  This is my area:

  <? for-each - group:current-group(); / RP_CURRENCY? >

  <? If: RP_CURRENCY = "ABOVE"? >

  <? for-each - group:current-group(); / RPT_DESCRIPTION? >

  <? If: RPT_DESCRIPTION = 'debit card '? >

  <? sum (current - group () / RP_CI_EQUIVALENT_CALC)? >

  <? end if? >

  <? end for each group -? >

  <? end if? >

  <? end for each group -? >

  If this field does not always reach the sum, and then returns a NULL value. I need it to return 0 instead, but I think I'm this overload since RTF are not flexible.

  I tried to reach '+ 0' at the end and it works when its null, but if the number is not null, then it adds a 0 to the result rather than adding it.

  The XML code is attached.

  Please use this amount

  And the code below will be more optimized for performance and maintenance.

• Get Null value online by using the reference line.

  Hi guys,.

  I get the null value of the line everytime I use the reference line. Here is my code.

  String rowReference = pageContext.getParameter (OAWebBeanConstants.EVENT_SOURCE_ROW_REFERENCE);

  Line OARow = (OARow) am.findRowByRef (rowReference);

  System.out.println ("row" + Row);

  If (line! = null)

  {

  System.out.println ("Surfing");

  Object succObj = row.getAttribute ("INTERFACE_HEADER_ID");

  String succStr = succObj.toString ();

  throw new OAException ("" + succStr, OAException.INFORMATION);

  }

  Thank you

  I found workaround to get a current line like «($OA.» CURRENT. Id_interface)"as REFERENCE of the LINE does not work. I'm passing the parameter to my Textinputbean in the application of process method and by capturing the current values in the process of request form

  Treat the claim code

  Hashtable params = new Hashtable (1);

  params.put ("param1", pageName);

  Hashtable paramsWithBinds = new Hashtable (1);

  paramsWithBinds.put ("param2", new OADataBoundValueFireActionURL (oamessage, "{$INTERFACE_HEADER_ID}" ""));

  updateIcon.setFireActionForSubmit ("updateRecord", params, paramsWithBinds, false, false);

  Process form Code

  If ('updateRecord".equals (pageContext.getParameter (OAWebBeanConstants.EVENT_PARAM)))

  {

  System.out.println ("after" m "+ pageContext.getParameter ("param2")); / / give you current value as $OA. CURRENT. ID_INTERFACE

• How to manage a transitional calculated attribute in my vo than sometimes groovy expression of null values?

  Mr President

  My worm jdev is 12.2.1

  In my transient VO sometimes attribute I have null values in the expression groovy

  (Purqty*Unitpurprice)+ (Purqty*Unitpurprice)*Staxrate/100
  

  Some products have sales tax rates, and some have Staxrate NULL.

  And I get the following error because of this.

  

  My question is that how to avoid this error.

  Concerning

  You can do a null control in your expression.

  If (Staxrate! = null & Salestax! = null) {}

  Return ((Purqty*Unitpurprice) + (Purqty * Unitpurprice) * Staxrate/100)

  }

  else {}

  Returns 0

• Remove data with null value

  Hello

  I'm using Oracle 11 g. I have a table with an id of 3, node, the value column. Combination of the column id and node, that must be taken account for deletion on the registers.

  Here, I need to delete lines with the NULL value in the value column. If for a combination of id and node with non-null values, then I need to delete rows with a null value for this combination.

  If the combination of id, node is not null value then this records should not delete.

  Below table, I need to remove the second row, for which is a value not zero VOICE CAL '10' is there, so I need to delete the row with null values. (VOICE, CAL, NULL)

  Network, FL, there is no value is non-null then I should NOT delete this line.

  This table is to have 100 s of this association, we can delete data in a single delete query?

  Or how I can delete rows with nulls for this combination.

  Tab1

  VALUE OF THE NŒUD ID

  VOICE CAL 10
  VOICE CAL NULL
  NETWORK NULL FL

  Thank you

  You can do this in a single DELETE statement (it is not a request), using an EXISTS or IN the subquery.  For example:

  REMOVE table_x m

  WHERE the value IS NULL

  AND THERE ARE)

  SELECT 0

  FROM table_x s

  WHERE s.id = m.id

  AND s.node = m.node

  AND s.value IS NOT NULL

  )

  ;

  If you would care to post CREATE TABLE and INSERT instructions for the sample data, and then I could test it.

• NULL values in partition Table of Partition key

  Hi all

  I'm using Oracle 11.2.0.3.

  I can add a null value on partition of Partition table key.

  If so, how?

  Kind regards.

  • You cannot specify NULL in the VALUES clause.

  Referring to clauses PARTITION you set - not the data that you insert.

  If you cannot define a range partition that uses the VALUES LESS THAN and use null to this division. But you CAN use NULL values in the VALUES of integration clause.

  DROP TABLE mytable;

  CREATE TABLE MyTable

  (

  CREATION_DATE DATE,

  Identification number

  )

  PARTITION BY RANGE (CREATION_DATE)

  (

  PARTITION prior_to_2016 VALUES LESS THAN (TO_DATE ('2016-01-01', 'YYYY-MM-DD'));

  LESS THAN PARTITION of VALUES undesirable (MAXVALUE)

  )

  Insert into myTable values (null, null)

  You can use a VALUES clause to insert NULL values - this line will go into the MAXVALUE partition.

• Separate s processed NULL values in indexes

  http://docs.Oracle.com/CD/B19306_01/server.102/b14220/schema.htm#i20690

  Indices and null values

  NULLthe index values are considered as distinct except when all non - NULL in two or several lines of an index, the values are the same, in which case the lines are regarded as the same. Therefore, UNIQUE i index prevents the lines containing NULL values to be treated as identical. This does not apply if there is not a no - NULL values - in other words, if the lines are fully NULL .

  The bold part: who's trying to tell me that the lines for the NULL indexed lines, that if these indexed 2 NULL values maintain the same values for the rest of the line that oracle treats as unique to them?

  That being said, the bold part is qualified with this statement:

  Therefore, UNIQUE i index prevents the lines containing NULL values to be treated as the same.

  
  

  
  

  
  

  In fact all this 2 average values in a single column being zero, with the rest of the line being exactly the same, is not treated as identical.

  
  

  I'm sure that's what the DOC tries to explain.
  

  Consider that you have a composit index SINGLE a two columns COL1 and COL2. And you want to insert some values like this

  ROWNUM COL1, COL2
  ------- -------- --------
  1 1 NULL
  2 2 NULL
  3 3 NULL
  4 3 NULL

  NULL values in the index are considered to be separate

  This statement indicates that NULL in COL2 values are considered to be UNIQUE values. If the NULL in COL2 ROWNUM 1, 2 are considered to be two different values.

  But the following statement

  except in the case of all values not NULL in two or more rows of an index are the same, in this case, the lines are considered to be identical

  This statement says ROWNUM 3, 4 for COL1, where they have identical values, where the NULL in COL2 value are not considered as UNIQUE values but as identical. That's why the 4 ROWNUM insert will fail with UNIQUE constraint violation.

• Bar chart stacked - strange behavior on display null values

  Hi all

  I'm trying to graph a county of the end dates of the activities over several years by months grouped by project.

  The problem I have is that there is a gap of 3 months where none of the activities that I am tracking complete. The default value for the stacked bar chart is to ignore the columns with no data (in my case it October-December 2015).

  To view these any given month I went to properties graphic and ticked the box "Include Null values. At this point, I get a very strange behavior. Once this option is selected, the legend explodes, showing each project in the database regardless if it meets my criteria for analysis.

  Has anyone another considering that happen? I'm doing something wrong?

  If it's important I'm in the OBI 11.1.1.7.150120

  Hello

  You have a filter on the list of projects you want to see?

  Based on the way you describe your analysis I guess you don't have any what filter on the list of projects, but some of the filters on the other dimensions/attributes and these filters were limiting the list of projects.

  If this is the case then what you see is not a weird behavior, but everything you've asked your analysis.

  "Include null values" is not limited to the time dimension, it fits any dimension of your analysis, so no filter on projects = all projects.

  How to reset the value of a list of entry of null values

  Thank you

  AR

  Place this code in your ViewRowImpl (base) class and use it when you need to reset _all attributes applied by LOV

  @Cvele: in fact, this will happen "by design" when you set the attribute which has attached lov to null, so there is no need of additional code.

  See also this blog: binary: prevent the execution of query unwanted in British Colombia ADF when used in Non - UI applications

  My previous answer is more related to this approach:

  DCBindingContainer bindings = (DCBindingContainer)BindingContext.getCurrent().getCurrentBindingsEntry();
  DCIteratorBinding iterator = bindings.findIteratorBinding("IteratorName");
  Row r = iterator.getCurrentRow();
  r.setAttribute("SomeAttrib", null);

• Freeze frame layer twinkle in gamma (?) when following a null value

  I thought I solved the problem by changing the quality and sampling area, but there are still questions, including a slight deformation based on casual. Any suggestions? I tried rendering framework, and with that same question. If I unparent it to my null value, the layer is a freeze frame plain ol again. The first image is fine, the following conditions are significantly different. The circulation area is low and there is no motion blur. The Null value is animated in the Position, scale and Rotation. I tried to disable rotation and scale, the problem persists.

  I had the help of Robert Kjettrup, who suggested that the problem was due to the complexity of the noise in the particular image I've used. Keeping this aspect, he proposed to conceal the lack of precision with a separate (unprocessed) layer which has been re-grainy, then use a mask of track in the areas you will need to re-grain with this layer.

  I normally Denoise my images, but in this case I had left it the shot as he was, so I was not used to meet a problem like this. Thanks also to Rick Gerard for his help also.
