Array of Ftree.Node type

Hi,
I'm using forms6i.
I want to create an array of nodes.
Like i have seen, using varray, to create array of varchar like
TYPE name IS VARRAY(4) OF VARCHAR2(10);
I want something like this
TYPE prev_node IS VARRAY(4) OF FTREE.NODE;
But when i'm using this, i'm getting Exception
Unsupported type in a VARRAY or TABLE type: FTREE.NODE.
Is there a way to create an array of nodes???
Help Please

Thank You BaiG
My requirement is , say i have a resultset(REF Cursor) with 3 columns say t1,t2 and t3
t1 should be added as root_node , and the return value for the add_tree_node() for t1 is to be stored in a variable(here i want to use array).
and t2 should be added as a child of t1.
node1 := Ftree.Add_Tree_Node(htree,
                                   Ftree.ROOT_NODE,
                                   Ftree.PARENT_OFFSET,
                                   Ftree.LAST_CHILD,
                                   Ftree.EXPANDED_NODE,
                                   getnodes.t1,
                                   NULL,
                                   getnodes.t1);
node2 := Ftree.Add_Tree_Node(htree,
                                   node1,                -- here im using previously added node
                                   Ftree.PARENT_OFFSET,
                                   Ftree.LAST_CHILD,
                                   Ftree.EXPANDED_NODE,
                                   getnodes.t2,
                                   NULL,
                                   getnodes.t2);This node1, node2 etc i want to store in an array.
Or since node1,node2 etc will be numbers, is it ok if i use varray of number??
Thanks

Converting object wrapper type array into equivalent primary type array

Hi All!
My question is how to convert object wrapper type array into equivalent prime type array, e.g. Integer[] -> int[] or Float[] -> float[] etc.
Is sound like a trivial task however the problem is that I do not know the type I work with. To understand what I mean, please read the following code -
//Method signature
Object createArray( Class clazz, String value ) throws Exception;
//and usage should be as follows:
Object arr = createArray( Integer.class, "2%%3%%4" );
//"arr" will be passed as a parameter of a method again via reflection
public void compute( Object... args ) {
    a = (int[])args[0];
//or
Object arr = createArray( Double.class, "2%%3%%4" );
public void compute( Object... args ) {
    b = (double[])args[0];
//and the method implementation -
Object createArray( Class clazz, String value ) throws Exception {
     String[] split = value.split( "%%" );
     //create array, e.g. Integer[] or Double[] etc.
     Object[] o = (Object[])Array.newInstance( clazz, split.length );
     //fill the array with parsed values, on parse error exception will be thrown
     for (int i = 0; i < split.length; i++) {
          Method meth = clazz.getMethod( "valueOf", new Class[]{ String.class });
          o[i] = meth.invoke( null, new Object[]{ split[i] });
     //here convert Object[] to Object of type int[] or double[] etc...
     /* and return that object*/
     //NB!!! I want to avoid the following code:
     if( o instanceof Integer[] ) {
          int[] ar = new int[o.length];
          for (int i = 0; i < o.length; i++) {
               ar[i] = (Integer)o;
          return ar;
     } else if( o instanceof Double[] ) {
     //...repeat "else if" for all primary types... :(
     return null;
Unfortunately I was unable to find any useful method in Java API (I work with 1.5).
Did I make myself clear? :)
Thanks in advance,
Pavel Grigorenko

I think I've found the answer myself ;-)
Never thought I could use something like int.class or double.class,
so the next statement holds int[] q = (int[])Array.newInstance( int.class, 2 );
and the easy solution is the following -
Object primeArray = Array.newInstance( token.getPrimeClass(), split.length );
for (int j = 0; j < split.length; j++) {
     Method meth = clazz.getMethod( "valueOf", new Class[]{ String.class });
     Object val = meth.invoke( null, new Object[]{ split[j] });
     Array.set( primeArray, j, val );
}where "token.getPrimeClass()" return appropriate Class, i.e. int.class, float.class etc.

How to handle unknown root node type when parsing?

Hello all, hoping someone knows how to accomplish this...
I'm trying to use XMLBeans to parse RIXML 2.0 documents. This schema allows for
multiple root node types, so I don't know when I'm trying to parse a file if the
root node is a Research node or a Product node, for example. If I try to invoke
parse and there is a type mismatch I get the following error:
com.bea.xml.XmlException: D:\RIXML\V2TestDoc.xml:0: error: The document is not
a Research@http://www.rixml.org/2002/6/RIXML: document element local name mismatch

So how do I generically handle parsing when I don't know what type of root node
I'm going to get?
Thanks,
Joe

Hello Joe -- You might try parsing the document as XmlObject (which your
schema-generated types extend). Then you could use an XmlCursor to discover
what the root element's local name is. Something like the following code
might be a way to do it. You could also simply re-parse the document after
discovering its root element name, but that would probably be more
expensive.
XmlObject xml = XmlObject.Factory.parse(mydoc.xml);
XmlCursor cursor = xml.newCursor();
cursor.toFirstContentToken();
if (cursor.getName().getLocalPart().equals("Research"))
// cast the XmlObject to your ResearchDocument type and use it.
else if (cursor.getName().getLocalPart().equals("Product"))
// cast the XmlObject to your ProductDocument type and use it.
cursor.dispose();

How to create an new array from dynamically discovered type

    public static Object toAdjustedArray(Object source, Object addition,
                                         int colindex, int adjust) {
        int newsize = 0;
        Class componentType = null;
        if (source.getClass().isArray()) {
            Object[] arrayIn= (Object[])source;
            componentType = arrayIn[0].getClass();
            newsize = arrayIn.length + adjust;
        else {
            System.out.println("error in ArrayUtil");
        Object[] newarray = new Object[newsize];
        copyAdjustArray(source, newarray, addition, colindex, adjust);
        return newarray;
    }This methods take an array as an input an append new value(s) to it.
I can get the component type of the array (i.e. the class of the array's member). But how can I create a new array of this component type (i.e doing something like componentType[] newarray = new componentType[newsize])?
CU Jerome

I fanally found a walkaround trick for my problem.
Their is no way to create an array of a certain type (dynamically dsicovered) in CLDC. But what you can do is to use the instanceof method to determine the type of your array and in a big if statement create the right array.
Here is the final code:
    public static Object toAdjustedArray(Object source, Object addition,
                                         int colindex, int adjust) {
        int newsize = 0;
        if (source.getClass().isArray()){
            Object[] arrayIn= (Object[])source;
            newsize = arrayIn.length + adjust;
        Object arrayElement = null;
        if (addition.getClass().isArray()){
            Object[] temp = (Object[])addition;
            arrayElement = temp[0];
        else{
            arrayElement = addition;
        Object newarray = null;
        if (arrayElement == null){
            newarray = new Object[newsize];
        if (arrayElement instanceof org.hsqldb.Index){
            newarray = new org.hsqldb.Index[newsize];
        else {
            newarray = new Object[newsize];
        copyAdjustArray(source, newarray, addition, colindex, adjust);
        return newarray;
    }

How can I define a new Search Node type?

Hi experts!
I'm trying to modify PPOME transaction, but I can't create a new Search Node type. Can anybody give me the necessary steps I have to do? Other question, Is it possible to create a new Search Node for a Organizational unit? Or this only could be possible for new objects types?
Thanks a lot,
Regards,
Rebeca

Hi Rebeca,
You need to create a Search node only if you create a new object type (e.g. ZP).
For org unit, you don't need to create one (unless you wanna change search details)
Otherwise, you can use existing search nodes for standard object types.
What you can do is, you can add a search node to an existing scenario in order to make it visible in the object manager part (left-hand side of the screen).
To create a new search node :
Goto SPRO Personnel management - Organizational Management - Hierarchy Framework - Object manager - define your own search node -
> Define search node : Add new entries here.
To add a search node to a scenario (e.g. to make a new search node visible on the left-hand side of PPOME)
Goto SPRO Personnel management - Organizational Management - Hierarchy Framework - Object manager - define your own search node -
> Scenario Definition (Object manager) : Select the scenario (for PPOME it is OME000), double click the "Search nodes" and create new entries to add the search node here. Then double click the "Search tool", copy the lines of a similar search node and change search node field to the new one.
Best regards,
Dilek

How do I fix "Invalid node type: selectionbox" error?

Ok I've got my document all made and nice and pretty, I use it to enter information and use the selection box to make visible the fields I need for each card. Then I save it and try to open it and get the following error popup message.
Invalid node type: selectionbox
Invalid node type: selectionbox
Invalid node type: selectionbox
Invalid node type: selectionbox
Invalid node type: selectionbox
Invalid node type: selectionbox
Invalid node type: selectionbox
Message limit exceeded. Remaining 10 errors not reported.
So I click ok on the error box. It opens the file with adobe reader like it's supposed to and then immediately I get the "Adobe reader has stopped working, windows can check online for a solution to the problem" and I get the two choices that both involve closing the program.
I got this once before and after about a half hour of fiddling with the original livecycle file it stopped doing it. I have no idea what I did to make it start or stop doing it and I'm not sure I even did do anything to cause it.
Has anyone else come across this problem? Does anyone know what I need to do to fix it?
I've included the file I'm having issues with.
Thanks,
Aaron

Hi Aaron,
I cant replicate your problem. What I did notice though, is when I make a selection on almost every selection box, I get the following error:
'cardtwo.TextField1 has no properties'. The error is coming from the following piece of code in the change event: 'cardtwo.TextField1.caption.text.value = (this.rawValue);'
I dont see a TextField1 in the cardtwo subform so I suspect that this field has been renamed and / or moved since that bit of code was added. Perhaps that would be a good place to start and could very possibly be the cause of your problem.

SOM expression - resolved to an incompatible node type of 'dataValue'

Hi experts,
i am working on wd abap interactive forms, i have taken a table on pdf and provided binding.. like data node is with data[*] and rest of the fields are maped preperly.
by default on initialization i fill some data this popup message is not coming..
if there is no data this message appears, when i fill some data manually and try to fetch i am not getting the records.
please let me know how to get rid of this message.
The SOM expression '$record.Z_TY_SFLIGHT_LIGHTS' for the dataRef specified
on field 'Table1', resolved to an incompatible node type of 'dataValue'.

If i maintain the cardinality of the table node 1..n it is not giving me the SOM popup.
instead of 0..n.

Assignment of node type in DRP

Hi,
       I f I define a Plant in R/3 and didnot define a node type in R/3 SPRO>DRP> Assign node types.
But when I Cifed the material to APO, it is transferred automatically as 1001.
1. How does the system know that it is a Location type 1001? or is it the default?
2. Are there any other settings that help the system decide the location type?
I noticed the R/3 SPRO> Enterprise Structure>Definition>Logistics - General>Define Location.
Thanks.

a plant is usually defaulted as 1001
unless you change the associated entry in the customizing table in the basic settings of DRP customizing
(customizing step Node Type Assignment --> Maintain Plant )
you can assign the following nodes here and they get mapped to the location types when they are CIFed into APO
A     Store
B     Distribution center
CD     Customer warehouse
DC     Distribution center
EW     Central warehouse
PL     Production plant
TS     Stock transfer point

How I pass a cluster with array of various data type (double, I32, string)

I have to pass from a VI to a Microsoft Visual C++ DLL, a cluster with some arrays of various data type. The problem is with Double array, that during Visual C debug is incorrect:the dimension is correct passed, but not array data. In the DLL I have inserted the C code genereted by LabVIEW. I tried to pass a cluster of only one array of double, and the results is the same. Then, I tried to pass a cluster with scalar number and the result is correct in only one case. If the double data is the first in the cluster, the result is correct; if the first is another data type, such as integer or boolean, the double data is incorrect during the debug of the DLL.
This is the code of my DLL:
// LabViewP
aram.cpp : Defines the entry point for the DLL application.
#include "stdafx.h"
#include "LabViewParam.h"
#include "extcode.h"
BOOL APIENTRY DllMain( HANDLE hModule,
DWORD ul_reason_for_call,
LPVOID lpReserved
switch (ul_reason_for_call)
case DLL_PROCESS_ATTACH:
case DLL_THREAD_ATTACH:
case DLL_THREAD_DETACH:
case DLL_PROCESS_DETACH:
break;
return TRUE;
typedef struct {
long dimSize;
double elt[1];
} TD2;
typedef TD2 **TD2Hdl;
typedef struct {
TD2Hdl elt1;
} TD1;
// This is an example of an exported variable
LABVIEWPARAM_API int nLabViewParamPass=0;
// This is an example of an exported function.
LABVIEWPARAM_API int LabViewParamPass(TD1 *pparam)
double parametro;
int i;
for (i=0;i<(**(*pparam).elt1).dimSize;i++)
parametro=(**(*pparam).elt1).elt[i];
return 42;
// This is the constructor of a class that has been exp
orted.
// see LabViewParam.h for the class definition
CLabViewParam::CLabViewParam()
return;
I use LabVIEW 7.0 and Windows XP.
Sorry for my english.
Thanks to every one for your suggestions.

It is hard tell for sure, but you might have alignment problems. The
key symptom
is that you can pass a cluster of big and small fine, but
small big doesn't pass correctly. You might also test this by seeing
what the size of your struct is. For Boolean and Double, sizeof()
should return nine bytes no matter what order the array is in. If you
are getting different sizes, you have two options. You can either order
them such that the sizes work, or you can build the EXE or a wrapper DLL
so that the alignment matches LV's native alignment.

How to create the query with multiple node types

Hi,
I am having an issue in creating a query to search multiple node types.
The requirement is to query documents/pages of the type dam:Asset and cq:Page present under a path.
I tried the following code snippet with no luck .
path=/content
1_type=cq:Page
2_type=dam:Asset
property=jcr:content/metadata/@cq:tags
property.1_value=<tag Name>
I was able to write a query with single type. However i could not find any documents/ materials with multipe types as shown above.
Thanks in advance.
Regards
Sudhi

I don't think multiple type is possible. Instead use super type like nt:base that will cover both page and asset.

Maintain values for node type supply chain

Hi,
Where can I update node type supply chain field of a plant? (t001w-nodetype)
Regards.

Alberto,
That's a good question. I have always assumed that this was part of the old DRP tool, and would be populated when you created your DRP network. Unfortunately, I have never seen DRP actually used, so I can't say for sure. Maybe some of the other readers will have an idea...

String array into formula node

Hello,
I am taking data from SQL, I am getting multiple rows of data for many different devices. I would like to wire the data into a formula node so I can sepearate and sort via script. However, I am getting an error for "Polymorphic terminal cannot accept this data type". Is there a work around? Can I not wire in a string array to a formula node.
/r
Travo

There are lots of basic string VIs that you can use to parse the string and separate out the individual fields. I would recommend "programming" your application using script nodes. Use the native language. LabVIEW is a fully functional and capable programming language.

Shift Register while Indexing Arrays in Formula Node

Hello,
I am having trouble using the formula node while indexing my two arrays. I keep getting "NaN" for my output array. I believe the problem lies within my shift register. My guess is that for the first calculation there is not a PreviousAngle so that is why it is giving me "NaN." For the first index I would like the value of the PreviousAngle to be 0. I am new to LabView and unsure what to do.
Thanks!

The shift register should contain 0 by default since you are using a double [if uninitalized, the shfit register takes the default value of the data type. In this case, the default Double is 0], but you should explicitly initalize the shift register to a default value in most cases.
To do so, right click on the "previous angle" shift register and select "Create constant". This will create a Double value of 0 to fill in the register for the first calculation.
If you need a number other than 0 to start, you can just change this constant.
**Note: This is a good habit to have. Shift registers retain value as long as the VI is in memory. So if you run this more than once, it will have the value from the last execution automatically! This is usually unintended behavior for new LabVIEW users -- however you can sometimes take advantage of this feature in some applications and make it intended behavior
