To Create a Dynamic Tree

Grant,
How to generate a Tree in Oracle 11g Dynamically.
Thanks & Regards,
Srikanth Reddy

What do you mean with 11g of Oracle. There is no 11g of Oracle Forms (which is the forum you posted this question in). Do you mean Oracle Forms 9 or 10?
If so have a search in this forum and in the help files. You will find examples and hints and tips on how to do it.
A general advice about using a forum like this is to show at least a little effort before you post a question. Very few people will take the time to show you from scratch how to do something that is described in the general documentation if you have not even read it and tried yourself first.

How to create a dynamic tree report

hi experts,
i have a requirement to create a dynamic tree report in OM module.
this report should show the number of people positions required in a org unit, and also the number of people available in a org unit.
There is something called as qualification catalog to which qualifications are attached, to these qualifications org units are attached, these org units will have some positions attached to it, and each of this position might have a person attached to it.
The user will enter the qualification catalog number in the selection screen for which he should be getting the result in a tree format which flows from qualification catalog to qualifications, from qualifications to org units, from orgunits to the total no of positions present in this orgunit and the no of positions occupied in the orgunit.
This is a challenging job as far as i am concerned.
Please suggest me a way to approach this,i promise to reward the answers.
thanks in advance,
santosh.

Dynamic Tree Creation using JSP, Struts framework

I urgently require tips/information/code snippet for creating a Dynamic Tree structure.
Tree is the hierarchical folder structure that we see in windows operating system.
Dynamic tree in the sense that all nodes shall be populated from database & a radio button shall be present at each node that can be selected & submitted to form.
Tree should be done using JSP (& if required Javascript).
I am using Struts framework .

after reading tutorial regarding to these 3 materials, you should be able to get your job done.

How to create dynamic tree based on BAPI

Hi
I am able to create dynamic tree based on flat file structure example given in SDN . But how to create the tree from BAPI directly.Also when I will be clicking on any leaf node of the tree some data related to the node will be passed to another view.
Regards
Ananda

What i'm trying to do is create an organizational structure.
Global>Region>Plant-->Corporation
The output from the RFC is a structure containing every possible combination for orgazational hierarchy. Basically a flat table with record for every possible combinaton of Region-Plant-Corporation. This data needs to be bound to a tree structure so that we can call BW queries based on that level. For example: Give me aged inventory for the SAP corporation within the plant Berlin that is located in the Europe region.
Now that you understand the business reason will the nodes that represent Region and Plant and corporation be non-singleton nodes or recursive? I was thinking a hierarchy of non-singleton nodes.
I can bind these nodes to the Region - Plant - Corporation elements returned from in the flat table structure. I will probably get duplicates as a specific Region will be listed multiple times for every possible combination of the data beneath it. I'm not so concerned about that right now as I want to make sure I understand how in Web Dynpro to bind the data to the tree.
Hopefully this makes some sense. Can you elaborate on how this may be constructed in context of the view?
Would i create a model node for region (0..n), model node for plant (0..n), and a model node for Corporation (0..n)?
Or does this sound totally incorrect?

We have 3 regions over 50 plants and probably around 500 corporations.

Has anyone created a dynamic two or three level tree?

Hi -
If anyone has created a dynamic two or three level tree, can you please explain and/or show a code example of how you did it? The 'dynamic tree tutorial' doesn't show the child node being created dynamically, but graphically.
I can build the first level fine, but how does the child node get associated with the parent node in the next level?
Thanks in advance.

Here's a snippet that might help. I'm sure there are more elegant ways to code it but this seems to work!
Good luck,
Keith
//1st Loop - executed once per first level of tree
for (int i = 0; i <= days; i++) {
j = i+1;
TreeNode newFirstNode = new TreeNode();
newFirstNode.setId("day" + j);
newFirstNode.setText("First " + j );
itineraryNodeChildren.add(newFirstNode);
java.util.List firstNodeChildren = newFirstNode.getChildren();
// Second Loop executed once per Second level within the First loop
for (int k=0; k<rk; k++) {
secondNumber ++;
TreeNode newSecondNode = new TreeNode();
newSecondNode.setText(secondNodeText);
firstNodeChildren.add(newSecondNode);
}

Creating a Dynamic Node for a Dynamic Graphic - Tutorial

Hi everyone,
I'm sharing my first tutorial, hope it'll be helpful for you.
In the Layout tab, it's possible to create an UI element "Business Graphic". It's a very simple tool that only requires a context node with a category attribute (that means, the values that will appear in the 'x' axis) and one or more series (each one with a color, generally a numerical value). It's possible to add a label for each series for better understanding of the Graphic.
Although it's a very powerful tool, there are some problems when we must create a graphic with N series and different labels. If the graphic use an ALV or internal table to fetch data, during runtime we can have more or less series. The definition of a static node and generic series is not enough in this case. That's why I'd like to present you this little tutorial to create a dynamic node that fetchs a dynamic graph:
In the WDDOINIT or Event Handler method that starts the application (once the data is available) we should create the dynamic node in the following way:
DATA: lr_node_info    TYPE REF TO if_wd_context_node_info,
             lt_attributes      TYPE cl_abap_structdescr=>component_table,
             attribute           LIKE LINE OF lt_attributes,
             struct_type       TYPE REF TO cl_abap_structdescr,
             lo_dyn_node    TYPE REF TO if_wd_context_node.
* Let's suppouse we can LOOP at the data table, so we can fetch the
* category data type (for example company name, month, year, ...)
* and each series with a numeric type
attribute-name = 'CATEGORY'.
attribute-type ?= cl_abap_datadescr=>describe_by_name( 'STRING' ).
INSERT attribute INTO TABLE lt_attributes.
attribute-name = 'SERIE1'.
attribute-type ?= cl_abap_datadescr=>describe_by_name( 'I' ).
INSERT attribute INTO TABLE lt_attributes.
attribute-name = 'SERIE2'.
attribute-type ?= cl_abap_datadescr=>describe_by_name( 'I' ).
INSERT attribute INTO TABLE lt_attributes.
* Once we have all the attributs for the node, we create a formal structure
struct_type = cl_abap_structdescr=>create( lt_attributes ).
* Now we can get the context information to add a new node
lr_node_info = wd_context->get_node_info( ).
* Create the node
lr_node_info = lr_node_info->add_new_child_node(
                    name = 'GRPH_DYN'
                    IS_MANDATORY = ABAP_false
                    IS_MULTIPLE = ABAP_true
                    STATIC_ELEMENT_RTTI = struct_type
                    IS_STATIC = ABAP_false ).
* Now we should populates the node, I'll create a hardcoded table,
* simulating the internal table that you should already have
TYPES: BEGIN OF tw_alv,
                    category TYPE string,
                   SERIE1    TYPE i,
                   SERIE2    TYPE i,
                END OF tw_alv.
TYPES: tt_alv TYPE STANDARD TABLE OF tw_alv.
DATA: lw_alv TYPE tw_alv,
              lt_alv   TYPE tt_alv.
lw_alv-category = 'Alfa'.
lw_alv-serie1   = 3.
lw_alv-serie2   = 8.
APPEND lw_alv TO lt_alv.
lw_alv-category = 'Beta'.
lw_alv-serie1   = 4.
lw_alv-serie2   = 4.
APPEND lw_alv TO lt_alv.
lw_alv-category = 'Gamma'.
lw_alv-serie1   = 1.
lw_alv-serie2   = 3.
APPEND lw_alv TO lt_alv.
* Now let's call the recently created node and bind the lt_alv table.
* Get node from context
lo_dyn_node = wd_context->get_child_node( name = 'GRPH_DYN' ).
* Bind table with ALV Container
CALL METHOD lo_dyn_node->bind_table
    EXPORTING
      new_items = lt_alv.
* It's always good to check if the table was succesfully binded.
* I refresh the lt_alv table and get the values from the node for controlling
REFRESH lt_alv.
lo_dyn_node->get_static_attributes_table( IMPORTING table = lt_alv ).
There are other ways of adding a node structure in the method add_new_child_node, but it works for me only with STATIC_ELEMENT_RTTI. The node is now created and has the data required for the graphic. Now, we should go to WDDOONMODIFYVIEW, or save the target view as a parameter, to create the graphic, bind the category and series and show it on the screen.
DATA: lr_graph       TYPE REF TO cl_wd_business_graphics,
              lr_cat           TYPE REF TO cl_wd_category,
              lr_series1    TYPE REF TO cl_wd_simple_series,
              lr_series2    TYPE REF TO cl_wd_simple_series,
              lr_container TYPE REF TO cl_wd_uielement_container,
              lr_flow         TYPE REF TO cl_wd_flow_data.
* Get the root element from the Layout or the specific
* container you have created for the graphic
lr_container ?= view->get_element( 'ROOTUIELEMENTCONTAINER' ).
* Creates a line busniess graph
lr_graph = cl_wd_business_graphics=>new_business_graphics(
        BIND_SERIES_SOURCE = 'GRPH_DYN'
        CHART_TYPE = cl_wd_business_graphics=>e_chart_type-lines
        HEIGHT = 340
        WIDTH = 750
        ID = 'GRAPH' ).
* Create the flow data for the new UI Element business graphic
lr_flow = cl_wd_flow_data=>new_flow_data( element = lr_graph ).
* Set graph in the root container from the Layout tab
lr_container->add_child( lr_graph ).
* Bind the category from the dynamic node to the dynamic graphic
lr_cat = cl_wd_category=>new_category(
                  view = view
                  bind_description = 'GRPH_DYN.CATEGORY'
                  tooltip = 'Company Name' ).
lr_graph->set_category( lr_cat ).
* Bind the two series from the dynamic node to the dynamic graphic
lr_series1 = cl_wd_simple_series=>new_simple_series(
                  bind_value = 'GRPH_DYN.SERIE1'
                  label = 'Sales'
                  view = view
                  tooltip = 'Average Sales' ).
lr_graph->add_series( lr_series1 ).
lr_series2 = cl_wd_simple_series=>new_simple_series(
                  bind_value = 'GRPH_DYN.SERIE2'
                  label = 'Purchases'
                  view = view
                  tooltip = 'Average Purchases' ).
lr_graph->add_series( lr_series2 ).
Finally we have created our business graphic. Test the application and you'll see something like the attached image.
Hope you'll find it useful.

A dynamic tree question

i have found some example about how to create dynamic trees... and also found and example wich is similiar to my case on how to Building a hierarchical tree from recursive tables(Frank Nimphius' Blogbuster)....
i have a answer.... i want for the same example to hve on the right of the tree a form in wich i can add the eleemtn in the tree.... so i need a form to add element , and three buttons to add , delet, and save elements from the forms, in the moment they are deleted from forms are also deleted from tree....
can anyone pls give me and idea how to do this :):) or there is any similiar example with this case..
thanks in advance !

Creating a dynamic jtree using datas retrieved by dom in xml parsing

help me with code to create a dynamic jtree using data retrieved as nodes by xml parsing using dom

Ok, so you want to make a tree. To determine the data that appears in a tree, you have to make a custom tree model. The API for this is at :
http://java.sun.com/j2se/1.4.2/docs/api/
A tutorial for using trees is at :
http://java.sun.com/docs/books/tutorial/uiswing/components/tree.html
I assume you are going to be using Nodes, since you are using XML. For this I might start with something like
class NodeTreeModel implements TreeModelI would then implement the 'getChildCount()' as the number of subnodes a node has, and the value of a tree node to the nodes value.
Hope that starts you off.

Create a dynamic form where selected text boxes appears, based on options chosen in a drop-down box

HELP!!! Can anyone please provide some guidance on how to create a dynamic form where selected text boxes appears, based on options chosen in a drop-down box.
I have a form which – based on the department that's selected from a drop-down box – will have different form fields/text boxes, etc, made available.
Is this possible in LiveCycle, if so, can you please provide the script/info - as needed.
Thanks,

In the preOpen event of the second dropdown list you put something like (in formCalc):
if (dropdown1 == 1) then
$.clearItems()
$.setItems("Year, 2 Year, 3 Year")
elseif (dropdown1 == 2) then
$.clearItems()
$.setItems("3 Year, 4 Year")
endif

How to create a dynamic RTF report which creates dynamic columns based on dynamic column selection from a table?

Hi All,
Suppose I have table, whose structure changes frequently on daily basis.
For eg. desc my_table gives you following column name on Day 1
SQL > desc my_table;
Output
Name
Age
Phone
On Day 2, two more columns are added, viz, Address and Salary.
SQL > desc my_table;
Output
Name
Age
Phone
Address
Salary
Now I want to create an Dynnamic RTF report which would fetch data from ALL columns from my_table on daily basis. For that I have defined a concurrent program with XML as output type and have attached a data template/data definition to it which takes in XML as input and gives final output of conc program in EXCEL layout. I am able to do this for constant number of columns, but dont know how to do it when the number of columns to be displayed changes dynamically.
For Day 1 my XML file should be like this.
<?xml version="1.0" encoding="UTF-8"?>
<dataTemplate name="XYZ" description="iExpenses Report" Version="1.0">
<dataQuery>
<sqlStatement name="Q2">
<![CDATA[
SELECT Name
,Age
,Phone
FROM my_table
]]>
</sqlStatement>
</dataQuery>
<dataStructure>
<group name="G_my_table" source="Q2">
<element name="Name" value="Name" />
<element name="Age" value="Age" />
<element name="Phone" value="Phone" />
</group>
</dataStructure>
</dataTemplate>
And my Day 1, EXCEL output from RTF template should be like this.
Name     Age     Phone
Swapnill     23     12345
For Day 2 my XML file should be like this. With 2 new columns selected in SELECT clause.
<?xml version="1.0" encoding="UTF-8"?>
<dataTemplate name="XYZ" description="iExpenses Report" Version="1.0">
<dataQuery>
<sqlStatement name="Q2">
<![CDATA[
SELECT Name
,Age
,Phone
,Address
,Salary
FROM my_table
]]>
</sqlStatement>
</dataQuery>
<dataStructure>
<group name="G_my_table" source="Q2">
<element name="Name" value="Name" />
<element name="Age" value="Age" />
<element name="Phone" value="Phone" />
<element name="Address" value="Address" />
<element name="Salary" value="Salary" />
</group>
</dataStructure>
</dataTemplate>
And my Day 2, EXCEL output from RTF template should be like this.
Name     Age     Phone     Address     Salary
Swapnill     23     12345         Madrid     100000
Now, I dont know below things.
Make the XML dynamic as in on Day 1 there must be 3 columns in the SELECT statement and on Day 2, 5 columns. I want to create one dynamic XML which should not be required to be changed if new columns are added in my_table. I dont know how to create this query and also create their corresponding elements below.
Make the RTF template dyanamic as in Day1 there must 3 columns in EXCEL output and on Day 2, 5 columns. I want to create a Dynamic RTF template which would show all the columns selected in Dynamic XML.I dont know how the RTF will create new XML tags and how it will know where to place it in the report. Means, I can create RTF template on Day 1, by loading XML data for 3 columns and placing 3 XML tags in template. But how will it create and place tags for new columns on Day 2?
Hope, you got my requirement, its a challenging one. Please let me know how I can implement the required solution using RTF dynamically without any manual intervention.
Regards,
Swapnil K.

Hi All,
I am able to fulfil above requirement. Now I am stuck at below point. Need your help!
Is there any way to UPDATE the XML file attached to a Data Definition (XML Publisher > Data Definition) using a standard package or procedure call or may be an API from backend? I am creating an XML dynamically and I want to attach it to its Data Definition programmatically using SQL.
Please let me know if there is any oracle functionality to do this.
If not, please let me know the standard directories on application/database server where the XML files attached to Data Definitions are stored.
For eg, /$APPL_TOP/ar/1.0/sql or something.
Regards,
Swapnil K.
