CMR filed returing empty collection

Hi, everybody!
I'm experimenting with EJB CMPs using Orion as Persistence manager and MySQL as database. I've made a simple one-to-many relationship with two tables, automatically created CMPs with Local interfaces with the relationship. Everything works fine, I can select the beans, access attributes...
Except, when I call the bean from the parent table to select the related entries in the child table, I get an empty collection. To be precise, the collection.size() states the correct number of child entries, but the iterator is empty, I'm not able to iterate over the children:(
Please help,
Igor

Hi there.. I have the same problem!! and I'm looking for a solution ??
I just want to tell you if one of us find it he will give the hand..
Okey dear!!!

Empty Collections and Empty Tags

It seems that empty collections from a cast or cursor result in an empty tag. For example, the following sql:select work.work_id medlineid,
cursor(
select
databankname,
db.accessionnumberlist_ref.accessionnumberlist accessionnumberlist
from table(dbl.databanks) db
order by databankname) databanklist,
cast( multiset (
select chemical_t(
wrkchm.cas_registry_number,
wrkchm.term)
from work_chemicals wrkchm
where wrkchm.work_id=work.work_id
order by wrkchm.term) as chemicals_t) chemicallist
from
works work,
databanklist_t_v dbl
where
work.work_id = 96264942
and work.work_id = dbl.work_id(+)results in the following XML:<medlinecitationset>
<medlinecitation num="1">
<medlineid>96264942</medlineid>
<databanklist/>
<chemicallist/>
</medlinecitation>
</medlinecitationset>Is there a way to not have these empty tags appear?
Thanks! -- John.

David, this is about understanding the use of, and differencies between tags and collections. This is a bit hard for many new users.
First of all searching for collections and tags can *not* be done simultaneously. You can either work with one collection only, or you can search for pictures with one or more tags.
Next collections should be used as either temporary work sets or for special occasions like specific vacations, trips or birthdays, e.g. "Anna 5 years". You say you have a collection named "Churches". I think would have made a TAG called "Churches" instead, because a tag is for general searches that can be combined. On the other hand I might have made a collection called "Church visits July 2005" or "Summer vacation 2005" or the like.
Another difference is that pictures in a collection can be sorted manually by drag & drop, while pictures found via tags always are shown in the order chosen in the Photo Browser Arrangement box shown bottom left in the Organizer.

Webapps tag - filters "lastclassified" and "randomclassified" producing empty collections

When using the {module_webapps} tag, the filters "lastclassified" and "randomclassified" producing empty collections. "all" and "lastest" are working OK.
Example code:
{module_webapps id="Member Directory" filter="lastclassified" itemid="Featured" template="" resultsPerPage="4" collection="members"}
{module_webapps id="Member Directory" filter="randomclassified" itemid="Featured" template="" resultsPerPage="4" collection="members2"}
{module_webapps id="Member Directory" filter="latest" itemid="Featured" template="" resultsPerPage="4" collection="members3"}
<pre><code>{{ this.members | json }}</code></pre>
<pre><code>{{ this.members2 | json }}</code></pre>
<pre><code>{{ this.members3 | json }}</code></pre>
Produces this output.

Contains Queries on Empty Collections

I'm running into the following problem when attempting a JDO query which
uses the .contains() operator on multiple collections, where one of the
collections is empty.
My class contains two vectors, both of which contain strings. I want to run
a query that returns all instances of TestClass that contain a certain
string in one of the two lists. I have done roughly what is outlined below.
1) The class looks like:
public class TestClass
private Vector _collection1;
private Vector _collection2;
2) The metadata in system.jdo looks like:
<class name="TestClass">
<field name="_collection1">
<collection element-type="java.lang.String"/>
</field>
<field name="_collection2">
<collection element-type="java.lang.String"/>
</field>
</class>
3) I construct the query as follows:
// pm is the existing persistence manager
Query query = pm.newQuery();
query.setClass( TestClass.class );
query.setCandidates( pm.getExtent( TestClass.class, true ) );
query.setFilter( "_collection1.contains( string ) ||
_collection2.contains( string )" );
query.declareParameters( "String string" );
Collection results = (Collection) query.executeWithArray( new Object[]
{ "searchString" } );
4) The resulting SQL query (for SQL/Server) looks like:
SELECT DISTINCT
t0.JDOIDX,
t0.JDOCLASSX,
t0.JDOLOCKX
FROM
TESTCLASS__COLLECTION2X t2,
TESTCLASSX t0,
TESTCLASS__COLLECTION1X t1
WHERE
t1.COLLECTION1X = 'searchString'
OR (t2.COLLECTION2X = 'searchString')
AND t0.JDOIDX = t1.JDOIDX
AND t0.JDOIDX = t2.JDOIDX
Suppose that the target string is located in the first collection of some
instance of TestClass. Also suppose that there are no strings in the second
collection. Under these circumstances, the query will not return this
instance.
Is there a way to work around this other than running two separate queries?
Is this a bug or is this the expected behaviour?
Any help on this is much appreciated.
Regards,
Sasha Haghani.

Hi David,
I've tried this approach as well and am now getting a different error.
Using:
1) query filter: "( _collection1.contains( var ) && var == param ) || (
_collection2.contains( var ) && var == param )"
2) parameter string: "String param"
3) variable string: "String var"
4) parameters: new Object[] { "value" }
The following exception raised is:
com.techtrader.modules.jdo.impl.jdbc.sql.SQLExceptionWrapper: [SQL=SELECT
t0.JDOIDX, t0.JDOCLASSX, t0.JDOLOCKX FROM TESTCLASSX t0 WHERE variable =
'value' OR (*variable* = 'value')] Line 1: Incorrect syntax near '*'.

com.techtrader.modules.jdo.query.QueryImpl.executeWithMap(QueryImpl.java:330
at
com.techtrader.modules.jdo.query.QueryImpl.executeWithArray(QueryImpl.java:3
93)
As you can see from above, the generated SQL statement looks like:
SELECT
t0.JDOIDX,
t0.JDOCLASSX,
t0.JDOLOCKX
FROM
TESTCLASSX t0
WHERE
variable = 'value'
OR (*variable* = 'value')
Additionally, if I change the filter to "( (_collection1.contains( var )) &&
(var == param) )", I get the following exception:
com.techtrader.modules.jdo.impl.jdbc.sql.SQLExceptionWrapper: [SQL=SELECT
t0.JDOIDX, t0.JDOCLASSX, t0.JDOLOCKX FROM TESTCLASSX t0 WHERE variable =
'value'] Line 1: Incorrect syntax near '*'. Severity 15, State 1, <rest of

at
com.techtrader.modules.jdo.query.QueryImpl.executeWithArray(QueryImpl.java:3

Again, the generated SQL looks like:
SELECT
t0.JDOIDX,
t0.JDOCLASSX,
t0.JDOLOCKX
FROM
TESTCLASSX t0
WHERE
variable = 'value'
We are using multiple queries for now and aggregating the results by hand,
so this issue isn't blocking us.

Hi Sasha,
One thing that appears "unusual", if you will, about your queries
is that you are using a parameter in the contains() method rather
than a variable. The spec mentions a different usage pattern along
the following lines: "collection.contains(string) && string ==
strParam" where "strParam" is declared as the parameter, and
"string" is declared as a variable. You may have already tried this
as a variation. Your usage appears permitted as far as the spec
goes, but may not have been tested for Kodo.

I tried three variations on the parentheses used in the filterexpression.
All yielded the same exception. I couldn't find any glaring errors or
omissions in the query. The string parameter is also properly declared.Is
this possibly another bug?
I'm executing multiple individual queries to acheive my goal for thetime

know when they are fixed. Thanks much.

Sasha,
This sounds like a bug. I will enter it into our database and get back
to you later.
Meanwhile, you may be able to work around it using something like
query.setFilter (
"(_collection1.isEmpty () == false && _collection1.contains(string))"
+ " || (_collection2.isEmpty () == false &&
_collection2.contains
(string))" );

How does hibernate determine type of an empty collection elements?

Consider we've got an instance of a class like this:
@Entity
class MyClass {
@ManyToMany
List<MyClass2> theList = new LinkedList<MyClass2>();
public List<MyClass2> getTheList() { return theList; }
public void setTheList( List<MyClass2> theList ) { this.theList = theList; }
.. id and its getter and setter here ..
As far as I know generic collection's type is erased after compilation. Therefore hibernate sees a raw-type collection in runtime. But it maps this many-to-many association from MyClass to MyClass2 correctly even if the list is empty. And in java persistence API documentation "targetEntity" property in @ManyToMany is optional also. It says "Default: the parameterized type of the Collection when defined using generics".
So there should be another way to determine collection element's type in runtime. Could anybody explain it to me?

The compiled class file still contains the information. Therefore you can get the generic type information for fields (using Field.getGenericType).
Objects on the other hand, don't contain that information.

Problem with an empty collection

When a procedure executes
FOR i IN g_tabla_situacion.FIRST..g_tabla_situacion.LAST
LOOP
END LOOP;
and g_tabla_situacion has no elements, ORACLE returns a
"*-6502:ORA-06502: PL/SQL: numeric or value error*"
How can I avoid this problem?
Now I am doing...
IF ( g_tabla_situacion.COUNT > 0 ) THEN
FOR i IN g_tabla_situacion.FIRST..g_tabla_situacion.LAST
LOOP
END LOOP;
END IF;
but it doesn't seem the best solution...
Thanks.

I was thinking in a solution that forces g_tabla_situacion.LAST to be lower than g_tabla_situacion.FIRST when I load g_tabla_situacion with no registers....Not sure what you mean, but if your collection is not dense (as in only these indexes are present: 1 - 2- 5) you will get an exception. The method that I showed you will always work correctly, regardless if the collection is Sparse (containing gaps) or if the collection doesn't contain any entries.

Cmr filed . urgent help me

hello
I want CMR-FIELD to be the part of compound primary key class. How can i do this
b/c compound primary key class only takes CMP-FIELD. please help, it is very
much urgent.........
i am using in j2ee with ejb2.0
thanx
sai

You should just specify the field as cmp-field as usual then add the field in the cmr-field tag in the relationships portion of the deployment descriptor. There should be no problem with identifying relationships where the primary key is also a foreign key to another entity.

Trying to retrieve list of rooms using EWS Managed API but it returned empty collection

Hi,
I'm trying to retrieve list of rooms using EWS Managed API. Before I have tried the following code I make sure our Administrator put all the rooms in a list following link https://technet.microsoft.com/en-us/library/ee633471%28v=exchg.141%29.aspx.
Here is the simple code I have used :
using System;

service.GetRoomLists() results "Enumeration yielded no results". Could anybody help me please ?

Enable tracing and see what the response from the server looks like. Also depending on your setup and how long ago your administrator created the list, it may take some

How to pass empty PL/SQL collection?

I can pass an array as PL/SQL associative array into PL/SQL procedure/block.
It works perfectly.
But i can't pass empty array (e.g. new decimal[] {} ) as value - exception raised:
System.InvalidOperationException:
"OracleParameter.Value is invalid"
I can receive empty collection FROM pl/sql, but can i pass empty collection TO pl/sql?

Unfortunately, there are no any suitable workaround for this problem in thread mentioned above.
Workaround given by Greg in the thread:
You can get around it in the meantime by using
Param1.Value = new string[1]{null};
Param1.Size=0;Why is that not suitable?

Put "Empty (as a verb) Collection" On Context Menu

Sometimes I just want to emty a collection without changing the folder/collection I'm in. I vote for "Empty Collection" on the "right/ctrl-click" menu of "not-smart" collections.

Tony:
What you say is true -- at least, the way you have said it.
What "Thriller novelist' says is also true.
I have agonized over having moved from 2007 to 2013 because of the loss of the old functionality. The
"...is still available..." portion of the AutoCorrect in the context menu takes a lot longer -- and usually at a time of literary inspiration, when I need to speed-up my keyboarding, not to retard it.
You have taken away very desirable functionality by this ...er, simplification in the 2013 release. In Outlook 2007 and Word 2007, my common keyboarding mistakes could be noted and I could add them quickly to the AutoCorrect list if
I chose to. Now, in 2013, I am losing untold hours of work when I must either slow down my keyboarding enough to prevent mistakes, or go back and make the now-slowed corrections.
Microsoft has dumbed-down the feature.
I cannot provide a screenshot of the old context menu, because I no longer have Outlook/Word 2007. Can't someone else at MS offer you a running Office 2007 edition, where you could watch how it works yourself?
Please restore the full former functionality of this feature. Your response dated 4/13/14 should not be marked as The Answer.
Thanks.

Is there any order for objects in a relationship collection

I am using two cmp ejbs A and B which are in a many to one relationship.
This is like : Any Order has 0 to * OrderLines.
For this my ejb A has a cmr fild of type Collection:
public abstract Collection getBs();
public abstract void setBs(Collection x);
My question is if there is any way to indicate the position in which the related objects are saved in the collection.
This is very important for me. Because I want to generate a view to the
user for ejb A that should be allways in the same order.
This is like:
The view of the "order" should show the "orderLines" allways in the same positions: first orderline, 2nd orderline , 3rd orderlin,....
And if the user replace the 2nd "orderLine" with an other orderline, next time the view should still show it in the 2nd position in the "order" page.
If I use the following code:
Collection x = getBs();
x.add(someObject);
It won't be in any specific position.
I wanted to do the following:
Collection x = getBs();
Vector v = new Vector(x);
v[anyPosition] = someObject;
setBs(v);
But then I read that I should never use the set method for a cmr field of type Collection! Because this will be done exclusively by the container!
So what to do?????

Hi sarkarati,
As J2EE requires the usage of the Collection interface, the only way is to order the OrderLine by hand before display.

How to remove target node if source field value is empty SAP PI Mapping

Hello,
how to remove target node if source field value is empty in graphical Mapping.
Like if
MIddle name in source filed is empty, I would like to eliminate target field from out put XML.
Thank you
John

Hi Jhon,
If you want to remove all empty tags and you dont to complicate your message mapping, you can use a XSL, after the message mapping, to remove all the empty tags:
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
    <xsl:template match="node()|@*">
        <xsl:copy>
            <xsl:apply-templates select="node()|@*"/>
        </xsl:copy>
    </xsl:template>
    <xsl:template match="*[not(@*|*|comment()|processing-instruction())
     and normalize-space()='' ]"/>
</xsl:stylesheet>

Finder methods that return collections (don't work)

Hi all, this looks like an internal error, but I though Id ask incase there is a way around it.
Im having some problems with entity java beans using jdeveloper and the internal j2ee server. The bean is deployed and runs, find by primary key and all other methods work except find by last name which returns a collection.
I have experimented with the code, and stepped through with the debugger. The debugger doesn't find any errors or throw any exceptions. The method which it calims causes the error ejb find by last name does not throw an error and exits normally.
Though experiments I have done I have found that the failure only occurs if the collection returned has elements. If and empty collection is returned then the error is not given. If null is returned then the same error is given with a null pointer exception at the start instead of class cast. I have tried serveral variations on this code and none seem to work. Im hoping this is a common bug and you can point me towards a solution.
I have browsed your forum and searched your site, as well as the web for information on this bug but have not found any information.
My OS is Linux Red Hat 8.0 and the version of JDeveloper is 9.0.2.8.2. I urgenly need assistance with this, it forms the basis for a final year degree project which needs to be submitted in 4 weeks.

I think I've figured it out. I checked my keywords and some of the keywords I used were unintentionally under another keyword, so it appears that smart collections useingn using child keywords will always include the parent keyword, even if that keyword isn't listed in the Keyword panel. When I moved the wrong children outside the existing parent, the Smart Collection worked properly. Now I have to figure out how the keywords unintentionally became children to other keywords.

Merging a collection into a table

I have a table with some blank columns.
I take all the data from the table in a collection and then process the data to fill those empty columns.
Now i have the collection with all the valid data.
Is it possible to cast this same collection into a table and merge it again into the original table?
I am trying to do so, but there is an error saying "cant use local collection"...
Any help on this would be appreciated.

Thanks a lot for your suggestion.
I would like to give you an elaborate process.
I have a table ABC. Some columns of that table are empty. I need to get those filled using some other tables.
Firstly, using a cursor I fetch the records in a collection say V_ABC.
Now in a FOR loop, I am fetching the missing data from other tables for every record in the collection and setting it in the empty places in the collection V_ABC itself.
So finally i have the collection V_ABC which has complete data.
The FOR loop is now ended.
Now i try to merge this V_ABC into tale ABC like this:
MERGE INTO ABC abc
USING TABLE(CAST(V_ABC AS TT_ABC)) z
ON (abc.random_column_name = z.random_column_name)
WHEN MATCHED THEN
UPDATE
SET abc.initially_empty_column = z.initially_empty_column
The exact error is "Error: PLS-00642: local collection types not allowed in SQL statements".
I am forced to use PL-SQL because of performance issues.
Could you provide an alternate way?
I guess one way would be to create another empty collection and EXTENDing it and creating a replica of V_ABC. Then probably it will allow me to merge. But i m not sure.
