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.

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...:-)

Htmlb:tree: Expand All

I tried to implement an "Expand All" functionality for my htmlb:tree. Strangely, I can change the nodes in the tree table, but they are still displayed as closed on the screen.
LOOP AT me->t_tree ASSIGNING <fs> WHERE status = cl_htmlb_treenode=>c_treenode_closed
                                         OR toggle = cl_bdv_co=>c_true.
      <fs>-status = cl_htmlb_treenode=>c_treenode_open.
      <fs>-toggle = cl_bdv_co=>c_false.
ENDLOOP.
Why is this? Has this anything to do with the TOGGLE functionality of the tree (which loads certain subtrees with a new server event) ?

>Has anybody an explanation for this
Delta-Handling is half Black Magic Voodoo anyway. I assume that the DH server side cache doesn't see any change in those fields (since you have removed them) and therefore doesn't resend them to the client (it only sends changed values).
The Client side cache still has the old values in memory and didn't get an update from the server. Therefore it still renders the old values.
You might try placing a delta handler block around your tree coding:
<bsp:deltaHandlerBlock id="protectionR2" >
    <htmlb:tree ... />
</bsp:deltaHandlerBlock>
You can try playing with the attributes of the DHBlock. Try attribute clientCacheClear when you want force a change to the tree.

[UIX] Tree - expanded state problem

Hi,
I'm experiencing problemswith my UIX Tree.
In my tree I expanded some nodes (so I can view its contents :))
Normally when I browse to some other pages and come back to the page containing the tree, it remembered the state in which I left it (same nodes still expanded). When I decide to insert new data (through a form page)to the database of which the tree 'feeds' itself, I get errors when browsing back to the page containing the tree, because it remembers its last state (which is nolonger valid, because of new records).
What I want is that I can go back to the page containing my tree, with the tree refreshed (containing my newly inserted data) and still leave those nodes expanded that expanded earlier.
Is this possible? (And is my problem clear? ;) )
Gr.
Philip

I'm afraid our proxy does not support mutable trees. The only way to have it work at all is to create a new proxy when you mutate the tree data, which means you will not be able to save the expanded/collapsed state.
This won't help you now, but ADF UIX is being migrated to ADF Faces which is based on JSF. In that realease mutable trees will be supported. There are early access releases of ADF Faces available here if you're interested:

UIX Tree for all who needs help!!!

Hi guys!!!
Uix team can`t write any examples of this subject, we decided to create it :-)...
There is an example of working tree with proxy for JDev 9.03!!!
All data takes from the DataBase. We use a ViewObject for DataBinding with hierarhical querry
(start with...
connect by prior... )! Dont forget to write this querry!
For using this querry U must use primary key (but not the rowID Item!!!!).
Don`t forget to change the name of your package, appmodule in UIX and Java!!!
There are Java & Uix files here!
If U have any questions ask us for e-mail: [email protected] !
With best regards,
Diamond Developer Team (Stukotiy Luda (advancd support), Chindakov Alex, Druppov Serge).
From Russia!
P.S. We will be glad to see the working example of hGrid with the same DataBinding!

Don't forget, you can make code easier to read by enclosing it in [code ] tags (without the space in the first tag), so it looks like this:
<provider>
     <data name="bundle">
          <bundle class="strings" />
     </data>
</provider> instead of this:
<provider>
     <data name="bundle">
          <bundle class="strings" />
     </data>
</provider>

Query regarding Expand all functionality in hier seq list.

              when i am trying to refresh the list, its displaying me the list with updated data in it
             properly BUT the only problem is the items are closed by default after refresh.
             so every time user needs to click the Expand option to view item records after refresh.
             Here I would like to have the items records expanded as well by default after Refresh.
             how to acheive this?
            Any suggestions to use any more methods or so..

Or if anyone knows the coding of Expand all pls refer to me,

Accordion creationPolicy="all" effect on tree expand

facing very strange problem
i have placed 2-3 tree component inside Accordion container.
On each tree's creationComplete i called function to expand first level.
when I set creationPolicy of Accordion to "all", tree expand is not working.
and if I removed creationPolicy from Accordion, all trees are expand to first level at creationComplete but only tree will not expanded.
and idea why this happen?

Your trees' creationComplete routines are being called at an earlier time than they were before. So maybe something isn't set up yet that they depend on.

'Expand All' icon in a tree structure?

Hi experts,
If we create a tree UI element in ABAP WD, we automatically get a 'Collapse All' icon.Is it possible to have a 'Expand All' icon as well?
thanks in advance,
Pras

Hello Pras,
You will not get any Collapse All icon when you create a tree UI Element .
You can expand or collapse the tree by clicking on the Parent Elements in the tree.
If you want to explicitly handle the Expand All and Collapse All functionality you need to put a button in the toolbar with name Expand ALL and handle it explicitly by setting attribute EXPANDED to abap_true for each and every element in the tree for Expand All action and vice versa for Collapse All.
Hope this is of some help.
Regards,
Ismail.

How to make the APEX tree in the "Expand All" shape by default?

Could anybody please enlighten me on how to make the APEX tree in the "Expand All" shape by default please? I created an APEX tree and by default it's in the "Collapse All" shape. I am using APEX 4.1.0.00.21

Hi,
you can check the view source of html and check the onclick code written on that plus sign(Expand All), just copy that onclick javascript code and put it on page javascript event.

DHTML Tree Expand-Collapse ALL buttons

Hi
I am using at DHTML Tree (in APEX 3.0.1) as a menu. I am wondering if it is possible to add buttons (or link) to the region which a user can click to expand all or collapse all nodes in the tree.
I don not want the tree to be expanded or collapsed all the time (as when using the Tree List template)
Thanks

Anyone?

How to remove Expand All in view menu of tree table

Hi,
I want to remove Expand All in view menu of tree table. How to do that?
Regards,
Raghu.

I am having the exact same problem.
However, I believe that displaying large amount of data via a tree table is fine as the user is able to quickly drill in to the data of interest.
It is just that the 'Expand All' option (as implemented) does not make sense in my case.
Given that I cannot hide it, is there an easy way to change it's behavior so that it does nothing (or provide an 'No implemented' alert).
I don't have the time/experience to implement custom menu items.
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

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?
Regards,
Denise
