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); persistOrderedKeys.commit(); }
"I don't know if it's one thing to eclipse debugger.
I had problems of this kind when I don't have a level of operating system for the device I am debugging on.

GetCurrentRow returns the null value while trying to values defined in table advanced VO
Hi all
I'm trying to set default values to a bean advanced table according to the selection of LOV in another region. Here is the code and getCurrentRow returns the value null and null pointer exception is throwed. Please let me know where Iam going bad.
if (pageContext. ) isLovEvent ())
LovInputSourceId = string pageContext. getLovInputSourceId ();
if ("poNumber". ) is equal to ()lovInputSourceId))
pageContext . putDialogMessage (new OAException()"inside Onclick"));
OAViewObject VO = (OAViewObject) am . findViewObject ()"L3APNonprojbasedpoVO1");
VO1 OAViewObject = (OAViewObject) am . findViewObject ()"L3APCodingInfoEOVO1");
VO . setWhereClause (null);
VO . setWhereClauseParams (null);
VO . executeQuery ();
VO1 . setWhereClause (null);
VO1 . setWhereClauseParams (null);
VO1 . setWhereClause ("1=2");
VO1 . executeQuery ();
if (null! = VO )
Row ReqRow = (Row) VO.first();
if (null ! = ReqRow )
int idx = VO . getRowCount ();
for (int xx = 0; xx < idx ; xx ++)
String Description = (String)VO. getCurrentRow (). getAttribute ()"ItemDescription");
Number Amount = (Number)VO. getCurrentRow (). getAttribute ("Amount");
String Company = (String)VO. getCurrentRow (). getAttribute ("Company");
String ProfitCenter = (String)VO. getCurrentRow (). getAttribute ()'ProfitCenter');
String Dept = (String)VO. getCurrentRow (). getAttribute ("Dept");
String Lob = (String)VO. getCurrentRow (). getAttribute ("Lob");
String Account = (String)VO. getCurrentRow (). getAttribute ("Account");
pageContext . putDialogMessage (new OAException()"inside loops'));
if (null! = VO1 )
{ am. invokeMethod ("createRow");
VO1 . getCurrentRow (). setAttribute ()'Description',Description);
VO1 . getCurrentRow (). setAttribute ("Amount",Amount);
VO1 . getCurrentRow (). setAttribute ("Company",Company);
} ReqRow = (Row)VO.next(); }
else {}
}
}
Here is the method in AM.
Public Sub createRow()
{
OAViewObject vo = (OAViewObject) getL3APCodingProjectEOVO1 ();vo.clearCache ();
If (!) VO.isPreparedForExecution ())
{
System.out.println ("project VO executed");
vo.setWhereClause (null);
vo.setWhereClauseParams (null);
vo.setWhereClause ("1 = 2");
vo.executeQuery ();
}
Line = vo.createRow ();
vo.insertRow (row);
row.setNewRowState (Row.STATUS_INITIALIZED);
}I modified your code a bit. This code does not require a method of AM.
If the problem still not solved.
If you want you can try this and let us know what happens.
if (pageContext.isLovEvent()) { String lovInputSourceId = pageContext.getLovInputSourceId(); if("poNumber".equals(lovInputSourceId)) { pageContext.putDialogMessage(new OAException("Inside Onclick")); OAViewObject VO=(OAViewObject)am.findViewObject("L3APNonprojbasedpoVO1"); OAViewObject VO1=(OAViewObject)am.findViewObject("L3APCodingInfoEOVO1"); VO.setWhereClause(null); VO.setWhereClauseParams(null); VO.executeQuery(); VO1.setWhereClause(null); VO1.setWhereClauseParams(null); VO1.setWhereClause("1=2"); VO1.executeQuery(); if (VO != null) { for( Row ReqRow = (Row) VO.first(); ReqRow != null; ReqRow = (Row) VO.next()) { String Description = (String)ReqRow.getAttribute("ItemDescription"); Number Amount = (Number)ReqRow.getAttribute("Amount"); String Company = (String)ReqRow.getAttribute("Company"); String ProfitCenter = (String)ReqRow.getAttribute("ProfitCenter"); String Dept = (String)ReqRow.getAttribute("Dept"); String Lob = (String)ReqRow.getAttribute("Lob"); String Account = (String)ReqRow.getAttribute("Account"); pageContext.putDialogMessage(new OAException("Inside for Loop")); if (VO1 != null) { Row newRow = VO1.createRow(); newRow.setAttribute("Description",Description); newRow.setAttribute("Amount",Amount); newRow.setAttribute("Company",Company); VO1.insertRow(newRow); } } } } }

Returns the null value in HasMap.get ().
Hi all.
Just read the docs of java on hashmap and was interested in this topic the get() method:
A NULL return value does not necessarily mean that the map contains no mapping for the key; It is also possible that the map explicitly maps the key null. The containsKey operation may be used to distinguish these two cases.
I took in a case, which has been talked about: If the map allow nulls, returned by get() null will be just one key of the pair-> null value. But the second case is not clear to me. Please, show me an example for the latter case, when get() can returned null.sphinks wrote:

Please, show me an example for the latter case, when get() can returned null.There is no second case. There is a single case, if you put a null value in a map, get() will return null. And because of that, if you need to know if a certain key is in the containsKey() worksheet should be used instead of the get() method.

Count (1) returns the null value in the Group of
Hi the gems... Good afternoon...
I read that the COUNT() function always returns 0 (zero) if there is no corresponding row in the table.
The following code returns 0 as expected:
But when I used the GROUP BY clause in the query, then he returned to nothing:SELECT COUNT(1) FROM book_table WHERE client_id = 10009 AND book_id = 5465465 AND book_sub_id = 'gfdf' AND amount = 78686
Why this is happening... Please suggest...SELECT COUNT(1) FROM book_table WHERE client_id = 10009 AND book_id = 5465465 AND book_sub_id = 'gfdf' AND amount = 78686 group by client_id,book_id,book_sub_id,amount
When you use just rely on its own (and you must use count (*) not count (1) as the optimizer based on CSSTidy will re - write internally to count (*) anyway)... then you say you want a count of all rows.
When you introduce the group by clause you say thay want returned a number of records within specific groups... but if there are no groups, he cannot give you a line for any group with its county equivalent, because there are no lines for the groups. With the grouping, you have must have at least 1 row per group to get an account for her.

Returns the lowest value of two fields
Hello
I have two domains that users manually enter in a form. Value1 and Value2.
Someone at - it suggestions on the best way to use JavaScript to return the lowest value of the two fields?
Thank you
Natalie
I think I misunderstood what you mean by any, I thought you wanted the calculated value to be None. The two fields value digital formats and modify the script for:
Custom calculate script
(function () {}
Initialize the array
aNums var = [];
Get the field values as strings
var s1 = getField("Value1").valueAsString;
var S2 = getField("Value2").valueAsString;
Convert values to numbers if not empty and add to the table
If aNums.push(+s1) (s1);
If aNums.push(+s2) (s2);
Set the value of this lesser field of entries
If both are blank, this field blank
Event.Value = aNums.length? Math.min.Apply (null, aNums);:
})();

resolveNode returns a null value when a variable is used.
LiveCycle Designer ES2, latest version
Hello
The following Javascript code, in the click event of a button, returns a null value for the variable opaque. When I manually enter the expected value the script works perfectly.
I tried various modifications of the resolveNode line such as var opaque = xfa.resolveNode (qPage); , but without success.
Also studied all the documents reference Adobe that I could find on the scripts and resolveNode. Any suggestions?
var qPage = (Cell12.rawValue + "AnchorField");
App.Alert (qPage);
Opaque var = xfa.resolveNode ("' $... qPage '");
App.Alert (opaque);
var nPage = xfa.layout.absPage (opaque);
App.Alert (nPage);
xfa.host.currentPage = nPage;Thank you
Ron
I tried your sample and it seems to work very well... but I'm not sure 100% that you are trying to do... .going to your initial question on the passage of a variable in the resolveNode resolveNode expects a string, so you must use the following syntax to create the string:
xfa.resolveNode ("$.." + qPage)
Note that the variable is outside the quotes as such the string $... is added to the content of qPage. This wil work if qPage is a string as well.
In your example you have defined qPage as an XFA object so that the syntax above will not work. If you intend to use the same way, you would use qPage.name so that the name of the field will be returned (this is a string) and it will be added to your expression of $ to make the $... ProductAnchorField
Thus, the expression would be:
xfa.resolveNode ("$.." + qPage.name)
Make sense?

FIRST analytical functions returns the null line
The following query returns a null line when there is no such thing as a line for the predicate. Is it a bug or expected behaviour. If so what is the meaning of the null row, is it not logical?

For example, the following query shows that there is 1 row in the group with the lowest name ("ADAMS"), but the column comm in all ranks of this group is null:
SELECT COUNT (*) KEEP (DENSE_RANK FIRST ORDER BY ename) AS total_cnt , COUNT (comm) KEEP (DENSE_RANK FIRST ORDER BY ename) AS comm_cnt FROM scott.emp ;

Hi, OTN
In short, the scenario is:
View object is based on an entity. There is a form to the JSF page.
I select a record by clicking next and previous. Then I click on create to display empty fields for the new record.
When I click on the button, I need to register a field value and a default value for the new fields to records.

createRootApplicationModule creates the new instance of the application module, thanks to which you did not receive the current line.

where clause to see if they contain the null value
So I've finalized my function but now am having some problems:
the bl field (or the v_bl parameter) has null values in it. When I run the function using the "Select FH ('ACCESS', NULL, 8675309') From dual; I get a NULL return value because it uses the variable to compare with q.bl and you can not have q.bl = null in a Where clause.
The main problem is when the parameters are passed, a line can have the same prob and site, but the bl might be different as null, which would give a different lname.
In where clause I need to have something that will compare the parameter with the bl field. Sometimes it's null sometimes is not, but we need to find the line concerned. I made the "BOLD" in the question police
Here are two possible lines in the data
prob bl site lname
ACCESS Smith 8675309 (null)
54321 8675309 Johnson ACCESS
so in theory, if the function is called with the parameters FH ('ACCESS', NULL, 8675306')
He would return the lname: Smith
and conversely FH ("ACCESS", "54321 ', 8675309") would return Johnson
Here's the function
create or replace
Function FH
(v_prob IN varchar2, v_bl IN varchar2, v_site IN varchar2)
RETURN varchar2
AS
v_lname varchar2 (16);
BEGIN
S.Lname SELECT INTO v_lname
Of
request q
JOIN THE
s response
On
(q.order = s.order)
WHERE
q.BL = v_bl AND - where it is
q.site = v_site AND
q.prob = v_prob AND
s.Lname IS NOT NULL;
RETURN v_lname;
END;
-When I run the FH ('ACCESS', NULL,' 86753) function, it returns an empty value and not the family name

Remove the NULL values and update the value according to the logic

Insert in VOLA (SRNO, ONE) values (15, null);
Insert in VOLA (SRNO, ONE) values (16, null);
I have to remove the NULL values in column 1, the problem is that the position of the NULL values are not fixed, and it can be any position. If all the lines of the columns are null, then throw it away.
If multiple NULL values are here so I have to do the math as follows to update null with the eigenvalues
1. If the first line is null then take the 2nd value in row and update it.
2. If the lines between both is null then take avg of prev and next value not null and refresh it.
3. If the last value in the column is null, then then take prev and update, in this case last two are null, so I have to take value of prev 14 value line update in
15th and 16th ranks.
I want to put this pl/sql logic, somehow, that I thought have loop and counter aapproach and loops through the elements and check and update.
But always looking for something better before looking to write code. No idea or help will be useful for me.

Then, if you want to save it. create the database result item and write trigger (When-validate-point) on amount and filed rates and the trigger code, write:result:=:amount*:rate;
To display the result on the form, create the database no item and change the formula property and write the formula.

How to convert the Null value to 0 after the outer join?

Is there a way I can convert these nulls to 0?
I realized that the null value is not stored in the table, it is just following the outer join because the NULL do not match records in other... So by default, I'm expected to get NULL values...
Is there way to present these nulls to 0?
