First row fix in web inteface
hello,
in web interface I would maintain the heading line (first row) always fixed . What is the code JavaScript to insert?
thanks
DG
What you want is something like the freeze frame solution in Excel ..
tough boss - I have not seen it in any web template so far - would liek to know if it is possible - will be very helpful. But if it can be done through standard HTML I can definitely tell you how to do it.
One work around would be to add a frame separately - something like a sinngle column with only the first column and then another table with everything else. Set the navigation block for the second table and include the dataprovider for the first column in the affacted dataproviders list for the navigation block - you can have the same thing. But I have seen something like this inJava Applet where you can have a floating column and the rest scrolls - but no idea how to do it in BW Web Templates. Or define your table structure in BW and try the above solution of two data providers.

P.S Just thought off my hat so the unstructured response.

How to keep the first row fixed in a JTable, with sorting, and bellow the headers ?
I am trying to change the following code so then the fixed rows will stay on top(but below the headers!), but when I change getContentPane().add(fixedScroll, BorderLayout.SOUTH); to getContentPane().add(fixedScroll, BorderLayout.NORTH); it stays above the headers. How can I put the first rows on top, but below the headers ? Thanks.

Fixed first row regardless of column sort
I have a report where I need the first displayed row always be a specific row that have the input fields (like text fields and select list .. etc), all columns in report are sortable. The problem is that when user sort the report by any column, the first row that have the input fields will not be the first row anymore because of sort.
does any one have an idea how to fix the input fields row at the top of the report (first row) regardless of sort?Why include the input fields in the report and not use page items at the top of the report region?

[Solved] 27.8.4 How to Create a VO on a REF CURSOR - Missing first row
Searching the forum I found: BC4J - Get one less row from view object.
Dive into BC4J related --REF CURSOR (Resultset)
The first message did not have any answers, and the second had a follow up question - still no answers though - and I thought I would try a different title.
(This is off topic, but it would be a great help if the search results also displayed the number of replys in the thread. That way, I wouldn't have to view the messages that don't have responses.)
(This will be deployed on a server that has the ADF for JDeveloper 10.1.2 installed, so using that version of JDeveloper to develop the app.)
Okay, back to the problem ==>
I created a VO from a ref cursor, using the manual as a guide. When I run a page that displays a read only table of the view object, I am missing the first row. (Always the first row!) I don't have any order set, and if I call the ref cursor in a Java program for testing, I see all rows and the count is correct.
One other point, when I call the page, I get the following validation error:
Validation Error
You must correct the following error(s) before proceeding:
* JBO-29000: Unexpected exception caught: java.lang.ClassCastException, msg=null
* null
I still see the table, it is just missing the first row of data.
In my form I have first, previous set, next set , and last
navigation buttons. If I press last then first, the error goes away. I still don't see the missing row though.
Any guidance would be appreciated! I can post my code, but it is pretty much the same code in the AdvancedViewObjectExamples.zip in the ViewObjectOnRefCursor example. I just substituted my two package calls (getRefCursor and getRefCursorCount).
Thanks, KenWent back to a backup copy of the source. Fixed the error. Now I'm back to just not being able to see the first row of data.
Additional Note: I had removed fields in the display. Once I truncated the ps_txn table in the schema defined by the model, the data would display (Still without the first record.)
Are there any examples that are more in depth than the few pages in the developer guide?

How to ignore the first row in a csv import
Hello
This is the file we want to add to the datamodel:
https://www.mediafire.com/?a9xrwrwu79whu18
(BTW this is the csv output from a neat & free software called Jstock)
Here is an image of the problem:
As you can see they add automatically a timestamp in the A1 cell ruining the possibility of a clean import.
Can anyone help with a query to fix this and get the real headers?Hi NicoPer,
To follow your M code. You have this lines #"First Row as Header" = Table.PromoteHeaders(Source).
This mean you use first line ( the line include "timestamp=1415926728041" ) to make
table header. So you no need to use Table.Skip function. You just use one more Table.PromoteHeaders to make second line to your table header. Below is your code:
let
Source = Csv.Document(File.Contents("C:\PATH\JSTOCK.csv"),null,null,null,1252),
#"First Row as Header" = Table.PromoteHeaders(Source),
#"Changed Type" = Table.TransformColumnTypes(#"First Row as Header",{{"timestamp=1415926728041", type text}}),
FirstRowAsHeader = Table.PromoteHeaders(#"Changed Type")
in
FirstRowAsHeader

Dynamic Table in PDF - only first row passed to the WD Java
Hi Experts,
I'm working with Web Dynpro for Java on WAS 2004s SP13, ADS for SP13 and LiveCycle Designer 7.1
I am facing a problem related to PDF-dynamic table generation.
I am creating the PDF form with a dynamic table, an empty row will be added, when ADD button is clicked, the row will be deleted when DELETE button is clicked. After form submit, only first row of the table is passed to the Web Dynpro. I'v tried to use different dataSource Context node structure without results. The structure diescribed in the thread [Dynamic Table - same data repeating in all rows; doesnt works for me. The same happend if i try to folow the advise from Wiki https://wiki.sdn.sap.com/wiki/display/WDJava/Creating%20Table%20in%20Interacting%20form%20using%20Web%20Dynpro.
Beside this, my DropDown list in the table column is not populated. I know how to populate the DropDown list outside of table. That's working fine. But the DropDown in the table just not respond on the click (is not going open). I'm pretty sure that this is a result of a Context node structure/binding issue.
Please suggest me how can i implement dynamic table and populate the data in table dropdown column.
Edited by: A. Mustacevic on Sep 7, 2009 12:18 AMHi Prabhakar,
You describe exactly my situation. The node which is bound to the table row has cardinality 1..n. Exactly Context structure is:
node dataSource (cardinality 1..1/ Singleton true) ======> dataSource of the Interactive Form
subnode TableList (cardinality 1..1/ Singleton true) ======> bound to the table in the Interactive Form
subnode TableWrapper (cardinality 1..n/ Singleton true) ======> bound to the table row in the Interactive Form
subnode TableData (cardinality 0..1/ Singleton false) ======> table data
attribute 1 ====> Context nodeattribute bound to the table row field
attribute 2
This structure is recommanded in the post that I found on the Forum (see the firs hyperlink in my firs post).
Is this structure correct? Why is not working?
Your link is not working. Can you post the correct one.
Thanks in advance.
Regards
Adnan

Iterator moves to first row on Timeout
I've been finally able to reproduce an issue that has randomly popped up in my application where some of the datapoints in my page seem to point to the 'first' row and not to the 'current' row.
Please consider the following test scenario:
- My taskflow consists on 2 pages: the first one automatically runs a query and shows a bunch or clickable results (Parent1, Parent2, etc). Upon clicking on any of the results page #2 displays the details.
- Page #2 is organized such that the top section shows datapoints coming from a Parent record and the bottom section render a bunch of tabs(showDetailItem) components where the children's datapoints reside.
- Now this is the issue I'm facing: If I go to the details page for let's say row #10 I can see as expected the datapoints for Parent10 as well as its correspondent child records. So far so good but if I leave the page unattended for about an hour and then try to switch to a different tab to my surprise what I see are the children of Parent1. The end result is that the top section is pointing to Parent10 but the bottom section which is the one that was refreshed after an hour now points to Parent1 in the previous screen.
It seems to me that I'm having a timeout issue that's causing the current ViewState to get lost.
My web.xml session timeout setting is set for 3 hours so I don't think this is the issue. Where else should I set this value?
Another alternative would be that regardless of the timeout setting I would like to catch this timeout event and automatically redirect the user to the login page but I'm not sure how to do this in ADF.
Any pointers are greatly appreciated.
Thanks,
MVHi MV,
There are 2 places were you can set the timeout one is the web.xml and the other one is the weblogic.xml. The former takes precedence over the latter, however I think your current timeout might be cause by weblogic.xml given that your web.xml already has 3 hours. In any case if you would like to redirect to another page after timeout, you need to create a PagePhaseListener, see this blog post for an example:
http://www.baigzeeshan.com/2011/07/how-to-automatically-redirect-to.html
Let us know how it goes,

Default value for first row in table after row has rendered
I have a master-detail type page where the first row in the detail table appears with no values when the page first renders. After the user enters some data in the master area, the default value is available. I then use something like this to set the default in one column of the first row:
MyVOImpl vo = (MyVOImpl)am.getMyVO1();
MyRowImpl voRow = (MyRowImpl)vo.first();
voRow.setMyAttribute("some value");
When I do this and run the code in the debugger, I can see that the default value is stored somewhere in the row object. However, the value is not displayed in the screen.
What must I do to get the default value to display after the user has tabbed out of the master data area, and before the user attempts to enter data in the row?Hi. Thanks again.
Here is more detail of the code:
if (pageContext.isLovEvent())
* Form was submitted because the user selected
* a value from the LOV modal window,
* or because the user tabbed out of the LOV input.
* This code executes when the event is either
* LOV_UPDATE or LOV_VALIDATE
String lovInputSourceId = pageContext.getParameter(SOURCE_PARAM)
// Find out the result values of the LOV.
Hashtable lovResults =
pageContext.getLovResultsFromSession(lovInputSourceId);
// Find out which LOV input triggered the event.
if (lovInputSourceId.equals("myLovItemId"))
String myDefaultVar = null;
if (lovResults != null)
myDefaultVar = "some stuff " + (String)lovResults.get("myResultItemId")
if (myDefaultVar != null && myDefaultVar != "") // yes, this is always true in this case
// now set the default for the first line.
// Added lines will be defaulted by the
// EO.create() method.
MyVOImpl myVo = (MyVOImpl)am.getMyVO1();
MyVORowImpl myVoRow = (MyVORowImpl)myVo.first();
myVoRow.setAttribute("myRowItemId", myDefaultVar); // THIS LINE DOES NOT CAUSE DISPLAY TO CHANGE
The problem, as noted in the code, is that setAtrribute() does not cause the default value to display in the field.
What can cause this, and what can fix it?

However, when I run a 64-bit build of the application, running on a 64-bit computer (Windows Server 2008 x64), using the 64-bit Oracle client and driver, a SELECT operation returns only the first row of the table.
Note that this is only happening with the ActiveX ADO components. ADO.NET is not having a problem.
In both cases I am connecting to the same database, which is Oracle 10.2 (32-bit) running on a different server. I have tested with Oracle client 10.2.0.4 and 11.1.0.7 and got the same result in both cases.
I have reproduced the issue with a simple table (one column, NVARCHAR2(255)) and simple code.
In the code, I execute "select count(*) from tablename" and get the correct record count (more than one record). But when I then open the recordset ("select columnname from tablename"), ADO reports EndOfFile after I have read the first row and called MoveNext on the recordset.
My Oracle knowledge is limited so I don't know if there are driver properties I should be checking.
Anyone have ideas?
Thanks in advance.For 10.2 it's fixed in 10204 Patch 21 and higher.
For 11.1 it's fixed in 11107 Patch 12 and higher.
Cheers,

Only first row of a mysql table is updated
Hi,
I'm using Netbeans 5.5 with Visual Web Pack and trying to update data, stored in a mysql table.
I use a dropdown list to select a row and show the data in various textfields. This works fine. The problem, that it's not possible to save changes, I enter in the textfields. Everytime only the first row of the table will be (over)written. This happens also with the derby database. I checked the tutorial about inserting, updatting and deleting, it works fine. But they use a table to make changes to the data, so the case is different from mine.
Can anybody give me a hint? I'm going crazy ...
Thanx in advance
Markusyes this sounds crazy. i encountered similar problem with textfields. if they are numerous type, don't forget to add integerConverter to the textfield. it helped me out in my case. hope this helps

Binding on an iterator always return the first row of the Children VO...
I have 3 pages:
A -- tree table bound to VO A; B is used to view the detail of a row selected inside the table; Inside B there is another table that contains the childrens VO of B. Select a row in the table will launch C to view the details of the children.
They are all in unbounded task flow.
From A to B, it works fine: Details of selected row inside the Table of A is showing correctly.
However, From B to C, selecting a row inside B, When C is launched, it always shows the content of the first row of the B's Children VO.
Any idea how this can be fixed? I want C page to show the details of the row selected in B's Table.
B's table is defined like this:
<af:table value="#{bindings.C.collectionModel}"
var="row"
rows="#{bindings.C.rangeSize}"
fetchSize="#{bindings.C.rangeSize}"
rowBandingInterval="1"
selectedRowKeys="#{bindings.C.collectionModel.selectedRow}"
selectionListener="#{bindings.C.collectionModel.makeCurrent}"
rowSelection="single"
id="rTable"
styleClass="AFStretchWidth"
columnStretching="column:c1"
autoHeightRows="20"
contentDelivery="immediate">
</af:table>
How can I fix this to correctly show the details of seleted row for C?
Edited by: user735345 on Oct 3, 2010 9:24 PMHi,
Is this code you provided for B table or for C table??
Do you have your partial triggers set correctly?

af:table, only the first row of the table is effect
Hi experts,
I have an issue about using the <af:table, needs your help:
1.The default selected line is the first line of the table(This should be ok).
2.Only the first line can react to my manipulate, such as select one line and click delete button.
3.While choosing the other line-->click the command button, the page will be refreshed and the selected one will turned to the first line. (Now the selected row, will be the first row). And will do nothing ,and has no action with the command button.
I have an page OVS_Server.jspx, parts of it is :
<af:table value="#{backVS.serverList}"
var="row" rows="20"
emptyText="#{globalRes['ovs.site.noRows']}"
binding="#{backing_app_broker_OVS_Server.serverListTable}"
id="serverListTable" width="100%"
partialTriggers="poll1 commandButton_refresh commandButton_searchServer"
selectionListener="#{backing_app_broker_OVS_Server.onSelect}">
<f:facet name="selection">
<af:tableSelectOne text="#{globalRes['ovs.site.selectAnd']}" autoSubmit="true"
id="tableSelectOne" required="false">
<af:commandButton text="#{globalRes['ovs.site.server.poweroff']}"
id="commandButton_powerOff"
action="#{backing_app_broker_OVS_Server.powerOffAction}"
partialTriggers="tableSelectOne"
disabled="#{backing_app_broker_OVS_Server.unreachableServer}"
/>
<af:commandButton text="#{globalRes['ovs.site.edit']}"
id="commandButton_edit"
action="#{backing_app_broker_OVS_Server.editAction}"
/>
<af:commandButton text="#{globalRes['ovs.site.delete']}"
id="commandButton_delete"
action="#{backing_app_broker_OVS_Server.deleteAction}"
/>
</f:facet>
<af:column sortProperty="ip" sortable="true"
headerText="#{globalRes['ovs.site.serverHost2']}"
id="column_ip">
<af:commandLink text="#{row.ip}"
id="commandLink_ip"
shortDesc="#{globalRes['ovs.site.viewUpdateDetails']}"
action="#{backing_app_broker_OVS_Server.viewAction}"
immediate="true"/>
</af:column>
<af:column sortProperty="serverName" sortable="true"
headerText="#{globalRes['ovs.site.serverName']}"
id="column_serverName">
<af:outputText value="#{row.serverName}"/>
</af:column>
</af:table>
One JavaBean OVS_Server.java,and part of it is :
public class OVS_Server {
private CoreTable serverListTable;
private VirtualServer selectedServer;
public void onSelect(SelectionEvent selectionEvent) {
selectedServer = (VirtualServer)serverListTable.getSelectedRowData();
public String deleteAction(){
if (selectedServer!=null) {
deleteServerOper.execute();
return "deleteServer";
Would anyone show some lights on it?
Thank you very much.Thank you for your reply!
But the example you mentioned also has the issue like one of the comments :
"Hi, on selecting the first row it displays the correct value, when navigating to another row still it displays the old value and not fetching the new selected row, actually I can see this on your sample screen shots... is there any way we can fix??"
Is there any resolution? -
Header and first column fixed in the table
Hi,
Our requirement is that we want to fix header and first column of the table.
It means that when we will move right or down through scroll bar then header and first column should be fixed.
Thanks,
AnumitHi,
To fix header, the approach followed can be as following:
a) Create dedicated table for header with no rows visible
b) Set the property to FIXED (I do not rememeber proprty)
c) Create another table with header visiblity to NONE and all data rows visible
For First Column fix: the following approach could be tried:
a) New Transparent container: Matrix layout
b) 2 tables A and B adjacent to each other : B in scroll container[only horizontal scroll enabled] and both associated with same node.
c) A will have only one column and B will have remaining columns
regrads,

Unable to refresh page when insert the first row in viewobject
I am using JDeveloper 10g to develop a JSP page, DataAction, AppModule and ViewObject. But when I am trying to use the following code to insert the first row, the page is not getting refresh. The quite weird thing is when I insert the second row, it returns me the first row as well as the second row. And it works well when I am trying to insert the third row, forth row....
//code in AppModule
ViewObject vo= this.getSampleView();
vo.insertRow(newRow);
vo.setNewRowState(Row.STATUS_INITIALIZED);
vo.setAttribute("STR1", str1);
vo.setAttribute("NUMBER1",new NUMBER(1));
vo.setAttribute("STR2", str2);
getTransaction().postChanges();
getTransaction().commit();
//Note: SampleView is a simply view created from a EnityObject mapping to a single table.
Anybody could help me? Thanks very much!//The following code is the method in AppModule, which is invoked when clicks on the Add Remarks button on web page.
public void addRemarks(String strCustCode,String strRemarks,String strUserID)
ViewObject voRemarks1 = this.getCrmCustomerRemarksView();
ViewObject voRemarks2 = this.getCrmCustomerRemarksView();
NUMBER newSeq = new NUMBER();
try
voRemarks1.setWhereClause(" CRM_CUST_CODE ='" + strCustCode + "'");
voRemarks1.setOrderByClause(" CRM_SEQ_NO DESC");
voRemarks1.executeQuery();
if (voRemarks1.getEstimatedRowCount()<1)
newSeq = new NUMBER(1);
else
Row row = voRemarks1.first();
NUMBER seq = (NUMBER)row.getAttribute("CrmSeqNo");
newSeq = seq.add(new NUMBER(1));
SimpleDateFormat tmpLocalFormat = new SimpleDateFormat();
Date tmpDate = new Date();
tmpDate = Calendar.getInstance().getTime();
tmpLocalFormat.applyPattern("yyyy-MM-dd");
System.out.println("NGNCM003 add Remarks with " + strCustCode + "," strRemarks "," + strUserID);
Row newRow = voRemarks2.createRow();
voRemarks2.insertRow(newRow);
newRow.setNewRowState(Row.STATUS_INITIALIZED);
newRow.setAttribute("CrmCustCode", strCustCode);
newRow.setAttribute("CrmSeqNo",newSeq);
newRow.setAttribute("CrmCreatedBy", strUserID);
newRow.setAttribute("CrmRemarks", strRemarks);
newRow.setAttribute("CrmLastModifiedBy", strUserID);
newRow.setAttribute("CrmCreationTimestamp",tmpLocalFormat.format(tmpDate));
newRow.setAttribute("CrmLastModificationTime",tmpLocalFormat.format(tmpDate));
getTransaction().postChanges();
getTransaction().commit();
catch (Exception ex)
throw new RuntimeException("Invalid Sequence No.");
