Are NULL Geometries allowed?

Hi
I know that: You should not have invalid geometries because there is no way to predict exactly what will not work when you have invalid geometries.
What's about NULL geometries. VALIDATE_GEOMETRY just returns NULL. Is it allowed to have NULL in a spatial layer of Table?
Philipp

Hi,
NULL geometries are allowed. You should set the geometry column to atomic NULL, i.e.
create table foo (bar number, geom mdsys.sdo_geometry);
insert into foo values (1,NULL);

JavaFX's null not allowed is a thorn in my side....

Hi All,
Rule: JavaFX's data types (i.e. Number, Double, String, Integer) can't be null.
My JavaFX Application listen's for real time data updates. Since this is a listener, it won't have a value til it get's the first update. Sounds fair enough... but they can't be null! So, I must use java.lang.Double instead. But all binding's convert the java.lang.Double null value to a javafx Double value of 0.0. So now I have broken logic in my program as 0.0 is a legitimate value and certainly does not signify 'null'. So, then it looks like I am stuck entirely with java.lang.Double everywhere! But then I'd need to do my own java.lang.Double -> fx.Double casting class/function to handle the cast conversion of each binding in order to interact sensibly with the JavaFX API (as it like's the FX Double everywhere and won't throw a nullpointer exception when casting).
Rule: JavaFX's sequences can't contain null entries.
Further more, I could say "Nope, I don't have a value/update yet so I will just use an object placeholder/wrapper with null assignment". In my case, JavaFX object's are multiple and ordered. Perfect for a sequence! Except, you can't store null in a sequence! Thus, if you are looking for a team's sport's top batsman.. the 3rd batsman and they don't exist yet.. then 'team[2] = null' wont insert! So how can I find and bind to the 3rd batsman? We'll either I avoid sequences, which means native array's or java collections... but then I can't really bind to them! Or, everytime the sequence changes I need to search/iterate over the entire sequence to determine if there is a 3rd batsman in the sequence (and that won't necessarily be the 3rd entry).
Both these 'null not allowed' rules cause significant problems and have huge flow on effects onto the code that uses them. I believe this is totally wrong and a bad feature of the language and completely contradicts autoboxing! The identification of a data type reference being null is extremely significant. It is the responsibility of the receiver of a null reference/argument to decided how they want to handle the null reference (see autoboxing nullpointer exceptions if you don't believe me and reasons not to use java primitives). Removing the ability for this to occur is a step backwards for functional programming. I know you will say that I could just use the java.lang.*, a fair claim... but don't forget this means more work! The very reason you might be considering JavaFX in the first place.
Anyway my rant is over, I really love JavaFX.... just not these x2 rules.

The technique PhiLho refers to is often called the "null object pattern". If done properly it needn't be hackish at all, and indeed it can simplify a lot of processing code. Even if the "primitive" values (Number, String, etc.) could be null, and even if you could put nulls into a sequence, you're probably better off putting in an actual object that represents the absence of a value. The reason is that when you go to process that data, instead of just processing it, you have to put in checks for nulls here and there, and do special-case processing for it.
Consider displaying a list of, say, the top five batsmen. You'll want to have a sequence of five batsmen, and you'll want to put five CustomNodes or something into a VBox to display the names, statistics, etc., something like the following:
VBox {
    content: [
        for (b in [0..<5]) {
            BatsmanNode {
                name: bind batsmen.name
innings: bind batsmen[i].innings
notOuts: bind batsmen[i].notOuts
visible: bind batsmen[i].valid
You can't do this if there were a null in the sequence, even if it were allowed. Instead, you should put a "fake" batsman object into the sequence, and make its "valid" variable be false. This way the corresponding BatsmanNode will be invisible. Or, you could have it display "(no entry)" in grey text, or something like that.
The point is that if you always have a real object there, even if it represents a "null" or the absence of a value, it removes special-case processing code and enables you to do things like bind to it.

Htmldb_item(s) are null but return query values

Hi,
I have used the following query to create a region (I've done many like this).
When I access the htmldb_application items in insert statements it works fine.
But, when I try to do an update statement the htmldb_application items are null;
even after returning & displaying the values on screen. Hope this makes sense.
Region:
Select x.establishment_name,
x.hsd_insurance_policy_number,
x.hsd_insurance_group,
x.del
from
(Select
htmldb_item.text(11,establishment_name,20) establishment_name,
htmldb_item.text(12,hsd_insurance_policy_number) hsd_insurance_policy_number,
htmldb_item.text(13,hsd_insurance_group) hsd_insurance_group,
htmldb_item.hidden(14,hsd_person_insurance_id) hsd_person_insurance_id,
htmldb_item.hidden(15,gen_establishment_id) gen_establishment_id,
htmldb_item.hidden(16,gen_adr_id) gen_adr_id,
htmldb_item.checkbox(20,gen_person_id) del
from hsd_insurance_v
where gen_person_id = :HSD_Per_Identifier
union all
Select
htmldb_item.text(11,null),
htmldb_item.text(12,null),
htmldb_item.text(13,null),
htmldb_item.hidden(14,null),
htmldb_item.hidden(15,null),
htmldb_item.hidden(16,null),
htmldb_item.checkbox(20,null) del
from all_objects where rownum < nvl(:P4300_ROWS3,2)) x
Update Statement:
Begin
for i in 1..htmldb_application.g_f11.count
loop
If htmldb_application.g_f11(i) is not null Then
Update HSD_PERSON_INSURANCE
Set
HSD_INSURANCE_POLICY_NUMBER = htmldb_application.g_f12(i),
HSD_INSURANCE_GROUP = htmldb_application.g_f13(i),
LAST_UPDATE_BY = :P4300_Updated_By,
LAST_UPDATE_DATE = to_date(:P4300_Updated_Date,'DD/MM/YYYY')
where
hsd_person_insurance_id = htmldb_application.g_f14(i);
Update Gen_Establishment_Entity
Set
ESTABLISHMENT_NAME = htmldb_application.g_f11(i),
LAST_UPDATE_BY = :P4300_Updated_By,
LAST_UPDATE_DATE = to_date(:P4300_Updated_Date,'DD/MM/YYYY')
where gen_establishment_id = htmldb_application.g_f15(i);
end if;
end loop;
end;

Susan,
In 1.5, htmldb_item.select_list_from_query didn't support "display extra values" behavior. Now it does and a tenth parameter (p_show_extra in varchar2 default 'YES') allows you to disable it with 'NO'.
In your example, the query selects only non-null commisions, but setting p_show_null=>'YES' gives you the first null row and the default setting p_show_extra=>'YES' gives you the last null row, which is the "selected" option for rows where the comm column is null.
Add ,NULL,NULL,'NO' to the function call to eliminate the unwanted row.

Values from a jsp page are null in Action Class

I am dealing with this bug for a couple of days an i didn't managed to break it. If anyone has an idea would he be so kind to share it with me.

Basically your form beans are the place holders or containers for your jsp attributes. It has to be mapped in such a way that when the form is submitted the user entered values get populated on to your form bean.
For Eg:
JSP
<html:form action="accountSearchResults.do">
<html:text property="myName" size="15"/>
//USE ONLY STRUTS TAGS IN JSP's. U CAN REFER TO
//http://struts.apache.org/1.x/struts-taglib/tlddoc/index.html
//THE PROPERTY NAME "myName" SHOULD BE DEFINED IN
//YOUR FORMBEAN WITH getMyName AND setMyName
//METHODS DEFINED
</html:form>
struts-config.xml
<form-beans>
     <form-bean name="addEditAccount" type="org.apache.struts.validator.LazyValidatorForm">
          <form-property name="myName" type="java.lang.String">
          </form-property>
     </form-bean>
</form-beans>
<action-mappings>
     <action path="/accountSearchResults" type="com.zzz.AccountSearchResultAction" name="addEditAccount" scope="request">
          <forward name="success" path="NextPage.jsp">
          </forward>
     </action>
</action-mappings>
Action Class
Since we have defined the form bean as a lazyvalidator instance you can use:
PropertyUtils.copyProperties(targetBean, form);to fetch the values entered by the user. Try to use struts tags in your jsp's and map the properties to your form bean variables. Hope that helps.

XML into table: Why do all my insert values are NULL?

Hello,
I'm pretty new in XML ... then I still learn a lot by myself !!!
I surfed to a lot of forums and examples ....
I have a XML file. I built a XSL file in order to insert a part of my XML file into a table.
The 2 files are loaded as CLOB into a DB table.
I wrote a PLSQL procedure for this job.
We are on a DB 10gR2.
As a result, all the inserted columns are loaded with NULL !!!! ....
I must have done something wrong ... for sure !!! but I cannot figure out.
Here are the files and procedures:

     DBMS_XMLSave.closeContext(insCtx);
     DBMS_LOB.freetemporary (l_clob_xsl);
     DBMS_LOB.freetemporary (l_clob);
END;
The result table is like this :
scfx>select * from item_club;
ITEM_CODE ITEM_NAME ITEM_PRICE
All the columns of each row are NULL !!!
Why?
Do you have any advice ?
Thanks if advance,
Olivier

So, if I understand what you mean ... I should write something like this :
     insert into item_club
          select t2.partnum, t2.productname, to_number(replace(t2.usprice, '.', ','))
          from odab_xml_tab t
          , xmltable('*' passing t.xml.extract('purchaseOrder/items/*')
          columns partNum varchar2(35) path '@partNum'
          , productName varchar2(35) path 'productName'
          , USPrice varchar2(35) path 'USPrice'
          ) t2
Its a change in our code.. but that looks nice !!!
Thanks,
Olivier

Some :New values are null in compound trigger

<h4>
Hello everybody,
I use Oracle 11g R2.
My problem is: Why certain :New.values are Null in the before statement only if I have an after statement (that do nothing) ?
My test case:
</h4>
create table TEST
ID Number,
CODE char(10),
SUBJECT varchar2(60)
alter table TEST add constraint TEST_PK primary key (CODE);
insert into TEST (CODE, SUBJECT, ID) values ('AAA ', 'Subject AAA', 1);
insert into TEST (CODE, SUBJECT, ID) values ('BBB ', 'Subject BBB', 2);
commit;
<h4>My problem:</h4>
create or replace trigger Test_Trg
for insert or update on Test
compound trigger
before each row is
begin
dbms_output.put_line( 'Before Each Row, New values= Id: '||:New.Id||', Code: '||:New.Code||', Subject: '||:New.Subject );
dbms_output.put_line( 'Before Each Row, Old values= Id: '||:Old.Id||', Code: '||:Old.Code||', Subject: '||:Old.Subject );
:New.Code := Nvl(:New.Code, 'CODE'||:New.Id);
end before each row;
after statement is
begin
dbms_output.put_line( 'After Statement' );
end after statement;
end Test_Trg;
<h4>Now if I do that:</h4>
update Test set Subject = 'The New Subject' where ID = 1;
commit;
<h4>The dbms_output is :</h4>
Before Each Row, New values= Id: 1, Code: , Subject:
Before Each Row, Old values= Id: 1, Code: USER1 , Subject: The New Subject
After Statement
<h4> (You can see that in the before each row, :New.Code and :New.Subject are Null!)
And the Data are:</h4>
select * from Test where Id = 1;
Id Code Subject
1 CODE1 The New Subject
<h4>Why the column Code is changed?
Now if I change my trigger (just removing the after statement)</h4>
create or replace trigger Test_Trg
for insert or update on Test
compound trigger
before each row is
begin
dbms_output.put_line( 'Before Each Row, New values= Id: '||:New.Id||', Code: '||:New.Code||', Subject: '||:New.Subject );
dbms_output.put_line( 'Before Each Row, Old values= Id: '||:Old.Id||', Code: '||:Old.Code||', Subject: '||:Old.Subject );
:New.Code := Nvl(:New.Code, 'CODE'||:New.Id);
end before each row;
end Test_Trg;
<h4>All work perfect!
My question is: Why certain :New.values are Null in the before statement only if I have an after statement that do nothing ?
Thanks in advance,
</h4>

I've got two 11.2.0.2 environments - one where this is reproducible, one where it doesn't seem to be.
I assume it must be a bug and one of these environments is patched.
I had a quick look at metalink and couldn't see an obvious match.
I might see if I can figure out differences between environments later.
There are a number of bugs around compound triggers.
I've been bitten before with a different compound trigger bug.

Shame - nice way to neaten up multiple triggers but too many issues.

Error in Application log SCOM mgmt server 25934 Credentials are null for user

Hi, We recently started getting errors like the one shown below on one of our SCOM management servers.
Any thoughts on what might be causing this and why this shows on a scom server. There is no VMM stuff installed on this SCOM server.
Thanks in advance.

Hi,
If agent is installed on the VMM server, it will collect the information and send it to SCOM server. The event indicates the SCOM agent tried to access the registry key that was included in the User Profile but failed.
Please specify a local account or domain account as the SCOM action account for a test.

Error: Target or source of mapping are null

Dear CAF experts,
I created one composite application project which has one entity and an
External Service (WebService). This entity has two fields "userName"
(shortText) and "password" (shortText). It has all CRUD methods and a
"logIn" method, which takes userName and password as input and gives
back the userEmailId as the response. I have defined this mapping (
between the attributes of the entity and the parameters of the
WebService method LogIn ) in the datasource tab of the entity. I marked
the entity as remote enabled and created a web service using it. Then I
deployed the CAF project to the J2EE engine and configured the WSDL URL
and the End point URL for the WebService in the "External Service
Configuration" application.
Finally I tested the service using the "Service Browser" application. It
simply throws the exception "ERROR. Target or source of mapping are
null!:".
Have I missed anything here? Any leads..?
Thanks,
Bala

Rene,
As mentioned aleady I've an attribute called "response" that is mapped to the userEmailId of the service.
The error in the browser is simply the same as the subject of this thread. i.e. "Error: Target or source of mapping are null"
The full exception is

Conditionally hide a Table in template if underlying rows of table are null

Hi Folks.
Very new to BIP but keen to learn.
I have successfully set up an RTF template and I can get it to run with my BIP.
I have defined a table in the report using the Table Wizard. What I'd like to do now is wrap the table definition in the document with a condition that checks if the underlying table values are null. I.e. if the table behind that particular section has no rows then I don't want to display the column headers etc. nothing.
I have tried adding the following before the table...
<?if:SEQ!=''?>
Then insert the table using the wizard..
Then finish with
<?end if?>
There's no whitespace between the if, the table and the end if statements.
I'm hoping to test that if SEQ is null then don't display the table.
Am I missing something simple or am I wildly off-track?
Any pointers appreciated.
Many thanks
Kind regards
Dogfighter.

Disregard last post.
MODS feel free to purge this.
It actually works.
Don't know what I was doing wrong but the code I quoted in the last post does what it's supposed to.
Just tired I guess.
Cheers

If numbers are null

Hi Friends,
We are migrating our forms application from 6i to 10g and we have some issues here.The one is ,if numbers are null we have handled that as mentioned below
IF NVL(l_numb1,' ') = NVL(l_numb2,' ')
THEN
ELSE
END IF;
This works fine in 6i , when migrated to 10g it shows error.
But when both the values are VARCHAR2 then no problem.
So I need to handle this in the entire application.I think the only problem
is substituting space(' ') for NUMBER variables.
Do I have any other alternative for this.
Note : It should work for both VARHCAR2 and NUMBER variables.
Regards
Marlon

I use for this case selfwritten Equal- and NotEqual-Functions.
IF pkg.Equal (Value1, Value2) THEN
END IF;
IF pkg.NotEqual (Value1, Value2) THEN
END IF;
here is the code :
FUNCTION Equal (P_Wert1 IN VARCHAR2,
                 P_Wert2 IN VARCHAR2) RETURN BOOLEAN IS
BEGIN
IF P_Wert1 = P_Wert2
OR (P_Wert1 IS NULL AND P_Wert2 IS NULL) THEN
    RETURN (TRUE);
ELSE
    RETURN (FALSE);
END IF;

Firefox MAC v30 with proxy needs authenticate"Cache Access Denied" sorry, you are not currently allowed to request: from this cache until you have authenticated

Firefox was working perfectly before we've updated it to version 30.0. It seems that the new version does not like our Proxy setting which needs users to auth with their AD accounts.
In the past version, Firefox will pop-up a box that allow you to type in the username and password, which works perfect. However, it does not pop-up anymore and gives me this error message.
The following error was encountered:
Cache Access Denied.
Sorry, you are not currently allowed to request:
http://www.google.com.au/url?
from this cache until you have authenticated yourself.
I try to manually set up the username in key chain and allow firefox to access it but Firefox seems do not access that key chain at all.
Is anyone have the issue with the proxy which needs authenticate in Firefox30.0? Does anyone know the possible solutions?
Many thanks!
Shuopan
------------------------------------trouble shoot update-----------------------------------------
Quite interestingly, Firefox will work for 1 minute after I am using Safari with that Auth proxy. However, if I am not touching Safari for 1 or 2 minutes, Firefox will stop working and pop up the similar error message.
tried network.http.use-cache = false but not work
Thanks
