Tree and Table UI element with same data source (context)
Hello,
I am trying to build an application which shows an tree and an table UI which shows additional information to the selected tree node. (like Windows Explorer)
I am using an context like this:
Class - - - - - - - - -- (Mapped value Node)
- SubClass - - - - - (Recursion Node)
- id - - - - - - - - -- - -(Value attribute)
- name - - - - - - - - -(Value attribute)
For the tree I am unsing this event handler
public void onActionClassNodeSelected(com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent, de.aequitas.sap.wd.java.easyclass.wdp.IPrivateEasyClassView.IClassElement element )
wdModifyView contains this:
public static void wdDoModifyView(IPrivateEasyClassView wdThis, IPrivateEasyClassView.IContextNode wdContext, com.sap.tc.webdynpro.progmodel.api.IWDView view, boolean firstTime)
//@@begin wdDoModifyView
IWDTable pictureTable = (IWDTable) view.getElement("PictureTable");
if(firstTime)
IWDTreeNodeType node = (IWDTreeNodeType) view.getElement("TreeNodeType");
node.mappingOfOnLoadChildren().addSourceMapping("path", "element");
node.mappingOfOnAction().addSourceMapping("path", "element");
I think I could use now
pictureTable.bindDataSource()
, but do not know where to get the needed parameter.
Thank You
Bernd

Hi,
Following is the code to do this
//Your existing code
IWDTable pictureTable = (IWDTable) view.getElement("PictureTable");
//use the following code for binding
IWDNodeInfo nodeInfo = wdContext.nodeClass().getNodeInfo();// Assuming class Node is bound to table.
pictureTable.bindDataSource(nodeInfo);

ArrayCollections with same data source
Hi Everyone,
Recently I got in a project which use Tree objects to visualize and manipulate objects. The data source of this object must to be the same but with different visualizations. In some views this tree will be filtered and in other places it won't. The data source must to be kept consistently, if an object is update in a tree, it should reflect the updates in the other Trees.
My question is quite simple, does ArrayCollections are really expensive objects in terms of memory even using the same data source? Or does it have to do with the fact they are manipulating different datasources as well?
Please share your experiences.
ThanksHi,
ArrayCollection is a very useful construct.
http://blog.flexdevelopers.com/2009/03/flex-basics-arraycollection.html
Just make sure you clean the open nodes and it will perform fine.

Now my problem is, that I need for every ROW of my table UI Element a different cell editor. I know how to change it for the column. But is not my issue. I want to have images (traffic lights red and green) in some rows. The other rows should have numbers. The coding works, so that I have all the data at the right place in my table, only the images are shown as a string, because the cells of these rows have the cell editor Text_View. I tried something with cell variants (with cl_wd_table_standard_cell), but it was not possible for me to get a cell variant "image" in these cells/rows were I need it.
I hope you understand my problem and now what to do here.
Thanks a lot in advance.

Need to create a new row in table with same data as Primary key, but new PK
Hello Gurus ,
I have a table with one column as primary key, I need to create a new row in the table, but with same data as in one of the rows, but with different primary key, in short a duplicate row with diferent primary key ..
Any ideas of how it can be done without much complication?
Thanks in advance for your reply.

I have written a binary file with a specific header format in LABVIEW 8.6 and tried to Read the same Data File, Using LABVIEW 7.1.Here i Found some difficulty.Is there any way to Read the Data File(of LABVIEW 8.6), Using LABVIEW 7.1?
I can think of two possible stumbling blocks:
What are your 8.6 options for "byte order" and "prepend array or string size"?
Overall, many file IO functions have changed with LabVIEW 8.0, so there might not be an exact 1:1 code conversion. You might need to make some modifications. For example, in 7.1, you should use "write file", the "binary file VIs" are special purpose (I16 or SGL). What is your data type?

Web Analysis : populate the same table with multiple data sources
Hi folks,
I would like to know if it is possible to populate a table with multiple data sources.
For instance, I'd like to create a table with 3 columns : Entity, Customer and AvgCostPerCust.
Entity and Customer come from one Essbase, AvgCostPerCust comes from HFM.
The objective is to get a calculated member which is Customer * AvgCostPerCust.
Any ideas ?
Once again, thanks for your help.I would like to have the following output:
File 1 - Store 2 - Query A + Store 2 - Query B
File 2 - Store 4 - Query A + Store 4 - Query B
File 3 - Store 5 - Query A + Store 5 - Query B
the bursting level should be give at
File 1 - Store 2 - Query A + Store 2 - Query B
so the tag in the xml has to be split by common to these three rows.
since the data is coming from the diff query, and the data is not going to be under single tag.
you cannot burst it using concatenated data source.
But you can do it, using the datatemplate, and link the query and get the data for each file under a single query,
select distinct store_name from all-stores
select * from query1 where store name = :store_name === 1st query
select * from query2 where store name = :store_name === 2nd query
define the datastructure the way you wanted,
the xml will contain something like this
<stores>
<store> </store> - for store 2
<store> </store> - for store 3
<store> </store> - for store 4
<store> </store> - for store 5
<stores>
now you can burst it at store level. -
MRP split purchase requisition with same date
Hi guru
When I run MRP, if there are more requirements for the same material with same date, the system creates one purchase requisition grouping requirements.
So, if I have two requirements of 3 and 2 pieces for material A, with date 18042015, the system creates one purchase requisition of 5 pieces
I tried to use a BADI in order to split purchase requistion and have in this case a purchase requisition of 3 pieces and another one of 2 pieces but maybe I wrong something because MRP works wrong.
Is there anyone that could give some tips about this request? Is there anyone that had same problem?
Thanks
Regards
RaffaeleHi,
Hope your BAdI is working now.
MD51 is used for project. It creates replenishment orders against a WBS element. After this, you can run MD01 which will create replenishment order by material/plant level.

Can i have xml elements with same name but one is having attrbt..?
Hi all,
I am suppose to take input from one system into BPEL.That system is auto gererating xml file. But that file is strange. It has two xml element with
same name but with completely different sequence. First one is having two comlexTypes while second is having 5 simple types.
Now the difference is First element is having attribute while second is not.
So is that file is correct.?
thanks a lot.
/mishitcan you post the file? or load the file into JDeveloper and check the syntax or use XMLSpy for validation of the XML.

What i use to develop complex tree and table in my web application?
hi guys
simply most of my work in my web application will be depend on:
1-tree
2-table
i need this tree and table deal with database table (or even tables) must be able to do every thing like add node/row/column, delete, update, drag-n-drop, various object nodes/cells like check-box, list, images...etc
i used JTree and JTable then stoped because i faced problems in dealing with applet/database, and i really didnt see this is perfect way to do that even i agree that JTree and JTable are excellent objects. i also start using ajax tree but i didnt see it robust to have all this complicated work with database.
by the way i need also master-detail UI table, but its easy to get this if i have good and flexable table object.
my rest pages developed by jsp, servlet, javascript, html...etc
so any suggestion to how i build this tree and table? i also heared about JSF, is it serve me?
thanksso if the only way to use JTree and JTable,There are other ways, but they're not Java and might be more complicated.
are there
any links you have discussing dealing database with
applet by keep applet away from direct connection to
my database?I'm not aware of links, but it's common sense. You don't want to expose the DB server to the internet, and instead contact a server for authentication that then forwards the request to the DB. -
Let all channels(with same data structure)run one program
Hello,
I want to let all channels with same data structure run one program,how can i program it?
Thanks!Hi charleen,
You're going to need to provide more details for us to help you. In general "channels" do not "run" programs. You can, however, run a program which loops over channels, checks their properties, and decides whether to include them in the overall analysis. What do you mean by "data structure"?
What do you want to actually happen in the "program"?

Connect an 1-D array of cluster of 3 elements with dynamic data
hi everybody.
I am trying to wire an 1-D array which consists of a cluster of 3 elements with dynamic data. The error that appears says that I'm trying to "connect two terminals of different types". Actually, what I want to do is write to a file the FFT data produced by the Spectral Measurements vi. In order to write to a file, I am using the Write to Measurement File vi, but I don't know if this is the right way to do this. Has anyone any idea about this problem, because I'm out of ideas....
Thanks a lot!!ok! This works really good! thanks a lot! now i'm facing an other problem...The output file does not contain the right data. I want to collect the FFT (frequency vs. amplitude) of a time signal and it gives me the record length and the sampling rate instead.
For example, if I use a sampling rate of 300 ksamples/sec and a record length of 1000 sampling points, the file to be created has one column containing the record length e.g.
0
1
2
3
498
499
and on more column containing almost zero values and the value of the sample rate. Do you have any idea why this is happening?
Thank you!! -
Is there any other table like BSEG with same fields.
Hi Abapers,
I want to use BSEG table.But due to some promblem BSEG table is not supporting.So is there any other table like BSEG with same fields.
can any one help me.
with regardsSince performance may be an issue when hitting BSEG table
Any of the below accounting tables can be used.
1.BSAD
2.BSAK
3.BSAS
4.BSID
5.BSIK
6.BSIS
These are normal database tables, not clusters. Normally every record from BSEG can be found in one of these 6 tables. The program which selects data
From these tables runs faster than from BSEG.
Plz reward if helpful.
Thanks.
