Web Interfaces: BPS-Hierarchy: Collapse/ Expand all nodes

Hello,
having a bps hierarchy in a web interface, is there any way to collapse/ expand all nodes at once (via a button)?
Cheers,
Simon

Simon
Web interface does not support the collapsing of hierarchy.
it will automatically expands hierarchy.
Thanks,

Tree table-initially expand all nodes raises error when closing a node 11g

Hello,
Frank Nimphius posted a blog entry about how to initially display all the nodes in a tree or table here:
[http://thepeninsulasedge.com/frank_nimphius/2007/12/19/adf-faces-rc-initially-expanding-all-nodes-in-a-tree-or-tree-table/|http://thepeninsulasedge.com/frank_nimphius/2007/12/19/adf-faces-rc-initially-expanding-all-nodes-in-a-tree-or-tree-table/]
This works very well. However, when the user tries to close a node, a NullPointerException is thrown.
Below is the stacktrace.
Does anyone know how to work around that issue?

OK I have tried Frank's suggestion about the 2 entries in the managed bean and it works but I cannot collapse my child node !
I have a Master-Detail-Detail setup.
In the Grandparent I have this :
RowKeySet rks = new RowKeySet(true);
table1.setDisclosureState(rks);
this.grandParentTable = table1;
and in my Parent table I have this :
RowKeySet rks = new RowKeySet(true);
table2.setDisclosureState(rks);
this.parentTable = table2;
ie the same.
In my child I have nothing just the default accessors.
The collapse works OK for the Grandparent but when I click Hide for the Parent it does not do anything - no error message either.
cheers

JTree - How to Expand all Nodes in the Tree

I have a tree that has one primary node, two sub-nodes, and multiple sub-sub-nodes under those. I want to expand (show) all these nodes in the tree when the tree first loads. I tried expandRow() but that only seems to expand one row at a time by entering a single integer for the row. Is there any way to expand all rows/nodes when loading the tree?

see
http://forum.java.sun.com/thread.jsp?forum=57&thread=148793

Expanding one structure node expands all nodes

I am running SAP 70103 in our test environment. I have a problem running an existing query (JAVA) that contains a keyfigure structure with multiple parent/child elements. The parent nodes are collapsed. When I execute the query through JAVA if you expand any of the parent nodes all the parent nodes expand rather than only the parent node you clicked on. Running the same query in BEx Excel (ABAP) the expand works fine. Is anyone aware of a Note for this issue? Thanks.

Thanks for the response. The note doesn't cover my issue exactly but the related notes will help me investigate further. Thanks again.

Expanding and Collapsing All Nodes in a TreeByNestingTableColumn

Hi Experts,
I'm using NWDS 7.0.18.
I have a table with TreeByNestingTableColumn (master column).
The child nodes are recursive nodes and are loaded at runtime with an action onLoadChildren when clicking the master column. My question is, when the hierarchy is in its initial state, only the root node is loaded into the table. But I want to add functionality for expanding all nodes in the tree. Is there a way to achieve this, I'm a little confused because the Hierarchy children havent been loaded yet.
Any suggestion will greatly help.
Regards,
Kunal.

Hi Kunal,
I got your problem.
To expand & collpase all the child nodes please modify the code as below.
Create two methods exapndAll & collapseAll and call these two methods in existing button actions.
as below.
public void expandAll( com.sap.tut.wd.treetable.wdp.IPrivateTreeTableView.ICatalogEntriesNode node )
    //@@begin expandAll()
     for (int i = 0; i < node.size(); i++) {
     node.getCatalogEntriesElementAt(i).setExpanded(true);
     if(node.getCatalogEntriesElementAt(i).getIsLeaf()==false)
          expandAll(node.getCatalogEntriesElementAt(i).nodeChildCatalogEntries());
    //@@end
public void collapseAll( com.sap.tut.wd.treetable.wdp.IPrivateTreeTableView.ICatalogEntriesNode node )
    //@@begin collapseAll()
     for (int i = 0; i < node.size(); i++) {
     node.getCatalogEntriesElementAt(i).setExpanded(false);
     if(node.getCatalogEntriesElementAt(i).getIsLeaf()==false)
          expandAll(node.getCatalogEntriesElementAt(i).nodeChildCatalogEntries());
    //@@end
public void onActionCollapseAll(com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent )
    //@@begin onActionCollapseAll(ServerEvent)
    collapseAll(wdContext.nodeCatalogEntries());
    //@@end
public void onActionExpandAll(com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent )
    //@@begin onActionExpandAll(ServerEvent)
    expandAll(wdContext.nodeCatalogEntries());
    //@@end
We are invoking the methods recursively to expand/collapse all the child nodes.
This works.

Charan

Expand All for Hierarchy in Layout

Hi all
Has anyone developed an 'Expand All Nodes' function for a BPS Web application? I have a layout which contains a hierarchy and I would like to be able to provide two buttons which perform an 'Expand All' and 'Collapse All'.
Cheers
Dimitri

If you want expand all levels in hierarchy then you could choose the appropriate level in the 'Expand to Level' option in layout cutomization in Web Interface Builder.
In our case i have set it to 5 so that when the layout opens all the cost elements appear.But it takes time if the layout is going to read lot of data.
There is also another option for layout customization called 'Collapse Lead Columns'.If you want both these options in the form of button then you may have to write BSP codes for this task.

Integrate WAD 7.0 Template into BPS Web Interface

Dear all,
We recently migrated to BW 7.01. We have an existing planning application running as a BPS Web Interface.
I now want to integrate a query output (data and chart) by using a web template designed with WAD 7.0 into the existing BPS web interface. I know how to do this with a web template designed with WAD 3.5. There is also a How-to paper available that explains it for 3.5. I'm struggling now to do the same with WAD 7.0. The syntax for the URL generation changed, that's one problem. There maybe more when actually calling the web template from the web interface(?).
I found some threads here in the forum dealing with this issue but no clear solution. Some posts even mentioned that integration of 7.0 web templates into BPS web interfaces is not possible at all. I would appreciate any information on this issue.
Thanks in advance!
Regards,
Ulrich Meier

Hello Ulrich,
the 7.0 web templates run on your BI Java server which has a different host name (and port) than you BW ABAP server which run the BPS web interface. The servers are different in Dev/QA/Prod so you need to generate the URL dynamically.
One way is to hardcode it in JavaScript. Something like: if CurrentDomain = ABAPDevDomain. Domain = JavaDevDomain. if CurrentDomain = ABAPQADomain. Domain = JavaQADomain. etc
A fancy alternative would be to put the Java domain and port into an exit variable which you could include in the BPS web interface (in a hidden DIV tag for example). Fill the exit variable using function RSWR_GET_DEPLOY_PORTAL_INFO. Then your JavaScript can pick up this value to generate the proper URL for the web template.

UIX Tree: "Expand All" Functionality

Hello,
I have a question about the Tree in UIX. We are using the Tree component in a UIX Page (JDeveloper 10.1.2). With the tree we also make use of the ClientStateTreeDataProxy class.
It is possible to expand and collapse the tree, but I want to have 1 button to be able to expand all nodes on the first level of the tree or if this isn't possible to expand all the nodes.
I have try to simulate this using struts actions, but I'm unable to simulate the state request-parameter. I also try to look if something is possible with the ClientStateTreeDataProxy class. Which possibilities are there to manipulate the tree component?
Thanks, Dennis

Thanx Jeanne,
You brought me on a idea with the UIX Developer's Guide and EXPANDABLE_EXPANDED value.
I couldn't figure out how the expand property was filled, because it wasn't done in the ADF BC ViewObject. We have a Utility class that creates a DataObject from the ViewObject Data and here the expand property was set.
Now it was easy to build a ExpandAll option. It is possible to access the HttpServletRequest object were the DataObject is created. By setting a attribute in the request I could react on that and give the expand property indeed the value EXPANDABLE_EXPANDED.

Expand all on tree when dataprovider is an object.

When I first start the application I would like to have the
tree and all nodes fully expanded. My RemoteService returns an
object that looks like the snippet below.
I have seen a lot of code on how to expand all nodes of a
tree, but I do not have a tree.selectedItem yet as I have just
created the app. I would like to add an expand all to the
creationComplete on the tree but I an not sure what to pass the
tree.expandItem. I have tried to pass tree.firstVisibleItem. I have
tried to iterate over the children of the root object of my
dataprovider. I can do it with xml but can't seem to figure it out
using an object. Any ideas?

I tested with your data structure and the following worked
for me. I called expandAll(myTree,true) on creationComplete and all
nodes were open on load.

Correct password doesn't work with Mail interface, but works with web interface.

Mail claims "The POP server “mail.nykayak.com” rejected the password for user “valerie”, yet when I log in through the web interface the password works. All other accounts work. Has anyone experienced this and found a solution?

Mackie, Welcome to the discussion area!
On your iMac G3, go to the AirPort menu and select the network name. It will prompt you automatically for the correct type of wireless encryption password.
I wouldn't trust selecting an option from Internet Connect.
In AirPort Admin Utility, what type of wireless encryption have you enabled? If it is WPA2 the iMac G3 won't be able to connect.
Also ensure that your AirPort Extreme base station (AEBS) is configured to work in an 802.11b compatible mode. The iMac G3 is only 802.11b.

Tree error, after Expand All, then collapsing any node, ORA-6502/6512

Has anyone seen this problem with the Tree?
Normal Tree mode works great, can expand and collapse nodes with no problem.
I can Expand All, Collapse All, and Reset Tree without problems.
However, if I select Expand All, and then try to collapse any node, I get this error.
Unexpected error ORA-06502: PL/SQL: numeric or value error: character string buffer too small ORA-06512: at line 1
My database is 9.2.0.4, and there are 1,138 records in my tree table, with id NUMBER(8), pid NUMBER(8), and name VARCHAR2(100).
my tree query is:
select "ID" id,
"PID" pid,
"NAME" name,
'f?p=150:2:&SESSION.::NO::P2_PARAM_ID:'||"ID" link,
null a1,
null a2
from "#OWNER#"."PARAM_TREE"
order by 3
My root tree query is:select "ID" id, "PID" pid, "NAME" name, null link, null a1, null a2 from "#OWNER#"."PARAM_TREE" where id=0
I checked the link to collapse, it was the same in normal mode or Expand All:http://umbriel.xxx.com:7777/pls/EDIWS_GUI_DEV/f?p=150:1:9757663040679228582:CONTRACT,69
Any ideas, I searched in the forum, saw something on 9.2.0.6 that sounded similar, but it was specific to 9.2.0.6, not 9.2.0.4..
Thanks, Joe

Hi all,
I have created a tree with over 20000 entries but I dont know how many nodes there are. I am using APEX 3.0.1.
Whenever EXPAND ALL ist pressed I am getting this error:
Unexpected error ORA-06502: PL/SQL: numeric or value error: character string buffer too small.
I am also using DIV together with javascript in the tree region so that the selected node is always on top of the page.
like you mentioned. Does this seem like a bug too you?

How to disable "Expand All" and "Collapse All" when no node in a tree

I have a <af:tree> inside <af:panelCollection>.
All items under viewMenu like "Expand", "Expand All Below", "Collapse All Below", "Expand All" , "Collapse All", "Scroll to First" and "Scroll to Last" are implemented by default.
When there is no node in a tree, "Expand", "Expand All Below", and "Collapse All Below" are grey out.
However, "Expand All" , "Collapse All", "Scroll to First" and "Scroll to Last" are still enabled to be clicked.
Is there any way we can diable them when no node?

When I highlight last node in the tree and all nodes are collapsed, I see "Expand All Below" enabled but "Collapse All Below" disabled. Which is expected. Expand All Below will expand all the child nodes under a node.
QA filed a bug said that "Expand All Below" should be disabled since no node below it. However, I don't find any place to control them. Can you confirm this? Or you know some way to do this?It it not a bug then. You don't have to control it and framework takes care of enabling and disabling it accordingly.
If you need to expand all the nodes programatically, check this out.

SEM-BPS 6.0 BPS_WB generate Web Interface BSP

Hi all,
We recently had a redirect of the portal connected to our NW04S BW development system and had worked thorugh the issues on the portal side so existing Iviews works (SEM-BPS 6.0).
We are now creating some new iview for a new applications but I cannot generate the BSP page. BPS_WB say that the BSP was generated correctly but when I try to test it, it says that http entry is missing and would I like to add it and when I say I do, it fails since I cannot generate a node under SICF since I do not have the authorization. I did an SU53 check and asked for 01 create on S_ICF_ADM but getting a lot of questions since 01 on S_ICF_ADM is reserved for Basis only on this project.
Another thing we are also concerned with is that some system settings that need to be done on the BW side might now have been done although Basis said all entries are changed..
I have to admit that the last time I worked with someone to set up portal connection to BPS was back in 2003 so I have to dig pretty deep into my memory and had been doing some quick searches but have not found anything obvious yet that would solve the regeneration issue except for the authorization addition which they are very hesitant about.
Any information or thoughts on this issue / problem would be appreciated.
Thansk,
Mary

Hello Mary,
I still work on BCS, so dont have BPS here. What I can do is to give you a summary of those things I had done in the past. Maybe it helps?
I gues you know that there are 2 diffren types of nodes: System nodes to enable connection to the web and the node for each web interface.
The required system nodes are describes in OSS 517484. I guess you have released them? Since BW Release 3.5 the web interface works with HTMLB. I guess you have activated thise too?`So the last possibility is from my point of view the web interface itself.
The node for the web interface existis already?
/default_host/sap/bc/bsp/sap/<your_web_interface>
In develop system the web interfaces will be activated manually normally. But in Prod automaticall because of not allowed customising. If the web interface has created such an entry already I think the only chance is to give the web interface another name in Development system - or to delete the existing node in the prod system (dangerous).
If this is not your problem, maybe another consultant has an idea?

Eckhard Lewin

Collapse All and Expand All functionality in Tree

Hi All,
I am using TreeByNestingTableColumn element to display the tree hierarchy .
Does anyone knows how to implement Collapse All and Expand All functionality for this tree (if someone have sample code for these functionality then it will be great for me) ?
Thanks in advance.
Ravi.

Hello Ravindra Sahu,
Code for EXPAND ALL button:
*step 1:Access node
lo_nd_tree_hierarchy = wd_context->get_child_node( name = wd_this->wdctx_tree_hierarchy ).
*step2: Extract all the table entries from node which is binded to table
lo_nd_tree_hierarchy->get_static_attributes_table(
    IMPORTING
      table = lt_tree_hierarchy ).
*step3:set element attribute Expanded to abap_true
    loop at lt_tree_hierarchy ASSIGNING <ls_tree_hierarchy>.
      <ls_tree_hierarchy>-expanded = abap_true.
    endloop.
*step4: Finally the updated data needs to be binded.
lo_nd_tree_hierarchy->bind_table( lt_tree_hierarchy ).
Code for COLLAPSE ALL button:
*step 1:Access node
lo_nd_tree_hierarchy = wd_context->get_child_node( name = wd_this->wdctx_tree_hierarchy ).
*step2: Extract all the table entries from node which is binded to table
lo_nd_tree_hierarchy->get_static_attributes_table(
    IMPORTING
      table = lt_tree_hierarchy ).
*step3:set element attribute Expanded to abap_true
    loop at lt_tree_hierarchy ASSIGNING <ls_tree_hierarchy>.
      <ls_tree_hierarchy>-expanded = abap_false.
    endloop.
*step4: Finally the updated data needs to be binded.
lo_nd_tree_hierarchy->bind_table( lt_tree_hierarchy ).
Please don't forget giving REWARD points...:-)
