Unable to expand Tree in EP (e.g. Portal Content)
Dear Portal Gurus,
We are on EP 6.0,SP12.
We are unable to expand any tree structure (including stanadard Tree Structure) inside EP.
I get the following message :
Could not load or refresh node Tree creation failed on node: pcd:portal_content .
Pls let me know what needs to be done.
Thx.
when I exported a transport package I saved it on Portal conect and after doing all the transporting, when I opened the content administration and try to expand the portal content, I get the following error:
Could not load or refresh node Tree creation failed on node: pcdportal_content
<a href="http://ing.perez.googlepages.com/portal.jpg" target="_blank"><img src="http://ing.perez.googlepages.com/portal.jpg" border="0" /></a>
I get this error from the log

But I have a problem
1. I can expand the child links in tree structure when I comment the exporting parameter CALLBACK_USER_COMMAND in the function Module 'RS_TREE_LIST_DISPLAY'.
2 But when i uncomment the exporting parameter I am unable to expand the child links in output.
Please let me know if i have missed something in the code.
Useful answers will be rewarded

Need to expand tree by passing treeId thr URL not by clicking manually.
Sub: Need to expand tree by passing Id thr URL.
Hi,
Here i have Library.java and ajaxTree.jsf files (collected from Jboss richfaces)
There is having a list of artist .
If u click on a particular artistname then the respective albums(with their checkboxes) will expand and show like a treenode.
just look at d url : "http://localhost:8080/richfaces-demo-3.2.1.GA/richfaces/tree.jsf?c=tree&albumIds=1001,1002,1005,1008,1009,1010&client=0"
I m passing album Ids and clientId in url browser and receiving in d Library.java.
I need to expand the required client tree to show albums without clicking on artistname rather by passing the clientId from Url.
I thnk one EventHandling class( PostbackPhaseListener.java ) is responsible for expanding but I m unable to understand.
How can I do it.
Plz help asap.

Unable to display tree view; Error when parsing an XML document (Premature end of file.)
Hi folks,
I am using a cascaded mapping in my OM. I have a graphical mapping followed by the Java mapping. It is a flat file to IDOC mapping. Everything works fine in Dev but when I transport the same objects to QA, the Operation mapping though it doesn't fail in ESR testing tool, gives the following message and there is no output generated for the same payload which is successfully tested in DEV. Please advise on what could be the possible reasons.
Unable to display tree view; Error when parsing an XML document (Premature end of file.)kalyan,
There seems to be an invalid xml payload which causes this error in ESR not generating the tree view. Please find the similar error screenshot and rectify the payload.

Can someone help me on this.
thanks and regards,

Unable to expand drop down by index UI element
Hi,
I have got one Drop down by index in my webdynpro form and I want to bind this to backend data. For this purpose, I created one adaptive rfc model and also did all this model binding, context mapping etc.
Now my context in view looks like this :- GetDropDown_Mn (parent node) , this has got child Output_DropDown which again has two value attributes Name and Text.
This is component controller code where you bind and invalidate
__Shell__Ca_Read_Cr_Drbox_Val_Input dropdown = new __Shell__Ca_Read_Cr_Drbox_Val_Input();
wdContext.nodeGetDropDown_Mn().bind(dropdown);
wdContext.currentGetDropDown_MnElement().modelObject().execute();
wdContext.nodeOutput_DropDown().invalidate();
I then tried to bind my UI element in view with Name attribute , but when I try to run my application , the field appears as read only, kind of non editable (blocked) and I am unable to expand my dropdown.
The readonly property of UI element is false. I have hard coded one value like " Please select from drop down list " and I want the backend values to come below this. For this, I have written code to append the backend values with the hardcoded value. Now the problem is my dropdown is blocked and not able to expand ( unable to click the arrow button), and I cannot see the other values in dropdown except the hard coded value.
Can someone please help me on this.
The cardinality of context node is 1..n, selection = 0..1 and I have set Leadselection = -1.
Thanks and regards,
SaiHi Sai,
You can use the below code to add the please select in ur drop down in wdInit() method
wdContext.nodeVn_Node().currentVn_NodeElement().setVa_Attribute("-Please Select-");
please use the name of node as u have created in the context.
and after that please check if yoy are getting values from RFC call or not.
if you are getting the values then try to change the selection property of that node to 1..n and comment the lead selection line that you have written.
hope this will help.
Regards

Unable to expand table (or 'any' object) node - permissions issue?
I am the dba for a database and hence have access to the system user. When I connect to the db through SQL Developer, I can expand the table node under any user and list tables. As I can with any object node.
I now want to create an admin user that has restricted capabilities, one of which will be to view objects, such as tables etc..
(I will ultimately do this via a role to allow multiple users to have the admin capabilities, but for now have just created an admin_user userid).
However, when I connect to the database using this admin_user userid, I am unable to expand any object node.
I have played with different permissions, granting 'select any dictionary', 'select_catalog_role', 'select on dba_tables' but the user still can not view any objects via the appropriate node. eg. attempting to go to Other Users - username - Tables just shows nothing. (There are no filters).
However the admin_user can run a SQL command to view the tables. eg. Select * from dba_tables, will list all tables for all users within the database. So they DO appear to have the appropriate access.
So why can't they see the tables in the tables node?
Is there some piece of configuration within SQL Developer itself that I have overlooked?

Unable to expand permanent memory Error
Hi everyone,
When running the MIDlet I'm coding I get a java.lang.OutOfMemoryError with the fellowing message: "Unable to expand permanent memory".
I tried to raise the heap size of the WTK emulator but no change. And what is more annoying is that the debugger won't step into the offending method.
Do you have an idea on how to solve this problem.
CU JeromeThe runtime tells me that on a total of 512kb of memory 467kb are free.
The offending method is initializing some arrays and populating them.

hi,
i've just installed sqldeveloper 1.2.1-32.13 on mac os x 10.4.11.
it's the first install for me, first install on this machine.
when connected to a database, in the left column of the main window i'm unable to expand virtually all of those nodes (tables, views, ...):
click on the triangle next to "tables", it opens a dialog "loading tables..." which then instantly disappears. no tables are being listed, and the triangle i just clicked on also diappears. no more clicking on that node possible. same is for views, indexes, ...
the db connection appears to be fine, since i can type a sql select command (on the right) and get a valid result.
i have the J2SE 5.0 set as primary java application runtime version. i have 1.5.0_07 which appears to be the latest release for os x (?).
any idea what's wrong?
thanks for your feedback.i get no messages in the system console, but launching from terminal shows a java exception:

JavaMapping in PI 7.1 Error:Unable to display tree view; Error when parsing
hi,
i get by testing in PI 7.1 (operation mapping) this ERROR:
"Unable to display tree view; Error when parsing an XML document (Content is not allowed in prolog.)"
this is my java-programm-code:
import java.io.FileInputStream;
import java.io.FileOutputStream;
import com.sap.aii.mapping.api.StreamTransformation;
import java.io.*;
import java.util.Map;
import javax.xml.parsers.*;
import org.xml.sax.*;
import org.xml.sax.helpers.*;
/*IMPORT statement imports the specified classes and its methods into the program */
/Every Java mapping program must implement the interface StreamTransformation and its methods execute() and setParameter() and extend the class DefaultHandler./
public class Mapping extends DefaultHandler implements StreamTransformation {
Below is the declaration for all the variables we are going to use in the
subsequent methods.
private Map map;
private OutputStream out;
private boolean input1 = false;
private boolean input2 = false;
private int number1;
private int number2;
private int addvalue;
private int mulvalue;
private int subvalue;
String lineEnd = System.getProperty("line.separator");
setParamater() method is used to store the mapping object in the variable
"map"
public void setParameter(Map param) {
map = param;
public void execute(InputStream in, OutputStream out)
throws com.sap.aii.mapping.api.StreamTransformationException {

SAXParserFactory factory = SAXParserFactory.newInstance();
try {
SAXParser saxParser = factory.newSAXParser();
this.out = out;
saxParser.parse(in, handler);
} catch (Throwable t) {
t.printStackTrace();
As seen above execute() method has two parameters "in" of type
InputStream and "out" of type OutputStream. First we get a new instance
of SAXParserFactory and from this one we create a new Instance of
SAXParser. To the Parse Method of SaxParser, we pass two parameters,
inputstream "in" and the class variable "handler".
Method "write" is a user defined method, which is used to write the
string "s" to the outpurstream "out".
private void write(String s) throws SAXException {
try {
out.write(s.getBytes());
out.flush();
} catch (IOException e) {
throw new SAXException("I/O error", e);
public void startDocument() throws SAXException {
write("");
write(lineEnd);
write("");
write(lineEnd);
public void endDocument() throws SAXException {
write("");
try {
out.flush();
} catch (IOException e) {
throw new SAXException("I/O error", e);
public void startElement(String namespaceURI, String sName, String qName,
Attributes attrs) throws SAXException {

throws SAXException {
String eName = sName;
if ("".equals(eName))
eName = qName;
if (eName.equals("NUMBER1"))
input1 = false;
if (eName.equals("NUMBER2"))
input2 = false;
public void characters(char[] chars, int startIndex, int endIndex)
throws SAXException {
String dataString = new String(chars, startIndex, endIndex).trim();
if (input1) {
try {

} catch (NumberFormatException nfe) {

Expand tree in WebDynpro ABAP application
Hi,
Currently I am working on a WDA application which contains a UI ELEMENT TREE. The tree is generated dynamically at runtime.
I was guided by the example of SAP "WDT_TREE". After generating the tree looks like this:
TREE
| __ NODE1
| __ LEAF1
| __ LEAF2
| __ NODE2
| __ LEAF3
| __ Node3
| __ LEAF4
| __ LEAF5
| __ LEAF6
Now I have bound the "expanded" property of the node to a context element and execute the following action in the WDDOINIT:
* Fill tables with the structure of the tree
fill_foldertable( ).
fill_filetable( ).
lr_current_node = wd_context->get_child_node( 'FOLDER' ).
lr_current_element = lr_current_node->create_element( ).
lr_current_node->bind_element( lr_current_element ).
lr_current_node->set_lead_selection( lr_current_element ).
lr_current_element->set_attribute( name = 'TEXT' value = 'Products' ).
lr_current_element->set_attribute( name = 'IS_EXPANDED' value = 'X' ).
* Create the root node
create_node(
EXPORTING
cur_element = lr_current_element
parent_key = 'Categories' ).
Now the tree is expanded, but i can't see EAF1 and LEAF2. I get them only by clicking again on node1.
Any ideas?
Regards.Hi All,
I found the solution for my question. Expand tree in Webdynpro application
Soultion
In the context node i.e used as a source for tree, you create a attribute
Attribute Name: IS_BOOLEAN
Attribute type : WDY_BOOLEAN
Default Value : X
And in Context node Un check the Initialization lead selection.
Now bind the Expand property of TreeNodeType with 'IS_EXPAND' which you have created just now.
This way the whole tree will be expanded.

Download error: Unable to expand "___" into "Downloads". (Error 2 - No such file or directory).
I keep on getting the message "Download error: Unable to expand "___" into "Downloads". (Error 2 - No such file or directory)" when I try to unarchive zip files that I have just downloaded. Can anyone walk me through how to fix this?
Possible solution if dealling with MobileMe gallery.
I ran into this problem while downloading my mobileme gallery albums and videos. I can't tell if that is where you ran into your problem or not, but if it is, this is what worked for me. Most of my albums downloaded and expanded successfully, however about 5 downloaded and would not expland giving the error you got. After several retries, I selected one of the albums, clicked the settings icon, changed the name (added "-2" to the name). This time the downloaded zip file expanded successfully. This worked for all of the albums that I had problems with. -

You need to read and follow the Boot Camp instructions. Boot Camp Assistant is already on your computer in the utilities forderf. You run Boot Camp Assistant. Part of the process is to to then download the Windows Support software. This download is then installed from within Windows.
There is no Boot Camp download that needs to be installed or unzipped from within OSx which you seem to be doing.
