How to avoid displaying a blank row in the table component
Hi,
I have a create insert button and a table as in a read only form.
Each time i click on a create insert button a popup appears were the person enter the corresponding values and on clicking submit button it has to show changes in the table and on clicking cancel button it has to go back to the page.
But even when i click the cancel there is still an empty row is shown in the table. Is there a way to avoid it ?
Thanks in advance.
I am using this managed bean to refresh the table.
public class popupRefreshBean
private RichTable refreshTable;
public popupRefreshBean()
public void refreshTable(ReturnEvent returnEvent)
AdfFacesContext adf=AdfFacesContext.getCurrentInstance();
adf.addPartialTarget(this.getRefreshTable());
// Add event code here...
public void setRefreshTable(RichTable refreshTable)
this.refreshTable = refreshTable;
public RichTable getRefreshTable()
return refreshTable;
}

How to avoid editing a deleted record in a Table component
Hi! Everyon,
I am building a prototype using JSC. In Page1.jsp, I have a table displaying the records. On column one there are buttons that allow the user to edit the record, including deleting it. My problem is: when somebody else deleted a record and if the current user tries to edit the same record by clicking the edit button on the corresponding row he will get the next record. Could somebody tell me how to solve this problem? Thanks in advance.
By the way, I do not access database directly from the Web part. Instead, I dropped a session bean's method on the Table compoment. In the edit button's event handler, I use
TableRowDataProvider row = (TableRowDataProvider )getBean("currentRow");However, since that record was deleted already I always get the next record.
With best regards,
DanielThank you very much for your help. And sorry for not explaining clearly.
I have a session bean that has getCities(), getCity(String code) and other methods. getCities() returns an array of CityDO objects and getCity(String) returns a CityDO object. class CityDO basically is a JavaBean containing city code, city name and other information. When I designed the web part using Java Studio Creator, I dropped a Table component to the design view first, then dropped the EJB method getCities() onto that Table component. Up to now, it is very similar to http://developers.sun.com/prodtech/javatools/jscreator/learning/tutorials/2/ejb.html and everything worked fine.
In order to edit a CityDO record, I added a column containg "edit" buttons into the Table component. If the user clicks the edit button we will show the CityDO in another page called editPage.jsp. In editPage.jsp, the user can update the city or simply delete it. Here is the major part of the event handler of the edit button in Page1,
public String editCity_action() {
TableRowDataProvider row = (TableRowDataProvider)getBean("currentRow");
String code = (String)row.getValue("code"); // "code" is a field in CityDO
CityDO city = null;
try {
city = cityClient1.getCity(code);
} catch (Exception ex) {
ex.printStackTrace();
return null;
getSessionBean1().setCity(city); // pass the city to editPage
return "editPage";
}Usually, the above logic is good. However, if somebody else deleted one city and the current user tries to edit that deleted city (it is still in his table), he gets the next city. The real problem is in editCity_action(),
row.getValue("code") returns an updated value, but I only need the old one.
You memtioned ArrayList. That could be a good solution. Suppose I have an ArryList containing the CityDO objects, if I can bind the table to my ArrayList that will solve my problem. Could you tell me how to do the binding in that case?
Thank you again.
With best regards,
Daniel
By the way, I do not access database directly from
the Web part. I do not understand what you mean by the above
statement.
Instead, I dropped a session bean's
method on the Table compoment. Can you explain further. What method did you drop on
the Table component?
In the edit button's
event handler, I use
TableRowDataProvider row =
(TableRowDataProvider
)getBean("currentRow");However, since that
record was deleted already I always get the next
record.Here is the delete code from
http://developers.sun.com/prodtech/javatools/jscreator
/learning/tutorials/2/inserts_updates_deletes.html.
As is is working on the rowkey in the page bean's
table, that should not be affected by other users in
other sessions, the rowkey should not change, even if
the underlying record has changed.
public String delete_action() {
form1.discardSubmittedValues("save");
try {
RowKey rk = tableRowGroup1.getRowKey();
if (rk != null) {
tripDataProvider.removeRow(rk);
tripDataProvider.commitChanges();
tripDataProvider.refresh();}
(Exception ex) {
log("ErrorDescription", ex);
error(ex.getMessage());
return null;
}What is the underlying structure for the table's
data. Is it a row cache from a query? Is it an
ArrayList? -
Need to add a blank row to a table when checkbox selected
Hi ALL,
I have a custom page having 2 check boxes and few fields , i am doing search operation by entering one checkbox checked and few other fields and data displaying in table region.
my requirement is when i select second check box and click one button as add new row it should create a blank row in the table, means table should availabe with a blank row so that user can insert data,
please help me on thsi
ThnaksHi there ,
If you 're working with advance table then you have an default option to create a blank row , please through topic 'add another row '
in jdev guide .
If you are working the regular table region then you might follow the below code suggested .
Create a new item of the type button ( not submit button ) and handle the event in PFR of your controller class
String addRow=pageContext.getParameter(EVENT_PARAM); // "addRow " is an event attached to table
if("addAnotherRow".equals(addRow))
am.invokeMethod("AddRow");
In AMimplementation class :
public void AddRow()
OAViewObject headerVO = (OAViewObject)getsdaPacelineWorkupHeaderUpdateVO1();
sdaPacelineWorkupHeaderUpdateVORowImpl rowh = (sdaPacelineWorkupHeaderUpdateVORowImpl)headerVO.getCurrentRow();
rowh.getPacelineHeaderId();
OAViewObject lineVO = (OAViewObject)getsdaPacelineWorkupLineUpdateVO1();
Row lineRow = lineVO.createRow();
Row lineRo = lineVO.last();
lineRow.setAttribute("PacelineHeaderId",rowh.getPacelineHeaderId());
lineRow.setNewRowState(Row.STATUS_INITIALIZED);
lineVO.last();
lineVO.next();
lineVO.insertRow(lineRow);
lineVO.setCurrentRow(lineRow);
lineVO.setCurrentRow(lineVO.last());
Note : Replace your vo name in place of sdaPacelineWorkupHeaderUpdateVO1()
Please let me know if you have any questions .

How to identify one specific row in the table STPO?
Hi!
How can I identify one specific row in the table STOP? As an input for my ABAP function I have MatNr, Plant, Alternative, BomUsage and Bom Position (0010, 0020...).

How to display more than 200 rows in the table?
Hi Experts,
Is that possible to display more than 200 rows in a Table.
when i query from table, it has 1000 rows, i want to display all the 1000 rows in the Table.
when i query, the values are displaying up to 201 rows only,
when i click next on 200 - 201 it throws Exception says
*"Query has exceeded 200 rows. Potentially more rows exist, please restrict your query."*
let me know how to display all the 1000 rows in a table without Exception.
Any idea will be highly appreciated.
Thanks
AswathThe number of rows retrieved is controlled by profile option "FND: View Object Max Fetch Size". I believe 200 is the default value. Pl see these MOS Docs

Excel export contains a blank row for the Report Header
Hi,
I am getting a blank row as the first row in my SSRS report when exported to excel. I have already taken care of following things,
1. I have hidden all of the Page Header items using Globals
2. The position of Report Body Tablix is 0, that means there is no space between report header and Report Body.
I have developed this Report in SSRS 2012, please let me know if any more details are required. I think even after hiding Header Items, excel creates a placeholder for page header. I can't remove header from my reports as it is needed to be published in
pdf.
Regards
MohitHi Mohit,
According to your description, you are getting a blank row as the first row in your excel report when you export the report to excel, you have hidden all the items in the Page Header by using the Globals, right?
This blank row is for the page header, although you have hidden all the items in it, but it will still display when export report to excel. Because we can’t hidden the page Header directly. Normally, we can hidden all the items in the page Header, So in
the design phase we can also see the blank area above the report body when preview.
We have an alternative way by add the “SimplePageHeaders” setting in “RSReportserver.config” file, after configuration the page Header will not display in the first row of the worksheet but is rendered to the Excel page header. In Reporting Services, the
“SimplePageHeaders” default value is “FALSE” and it indicates that the page header is rendered to the first row of the worksheet. In order to display the page header in the Header/Footer section of Excel, we need to set the “SimplePageHeaders” setting value
to “TRUE”. I did a test on my local machine and here are my steps:
Navigate to RSReportserver.config file: <drive:> Program Files\Microsoft SQL Server\MSRS10.MSSQLSERVER\Reporting Services\ReportServer\RSReportserver.config.
Backup the RSReportserver.config file before modify it, open the RSReportserver.config file with Notepad format.
Set the Excel rendering extension code like this:
<Render>
<Extension Name="EXCELOPENXML" Type="Microsoft.ReportingServices.Rendering.ExcelOpenXmlRenderer.ExcelOpenXmlRenderer,Microsoft.ReportingServices.ExcelRendering">
<Configuration>
<DeviceInfo>
<SimplePageHeaders>TRUE</SimplePageHeaders>
</DeviceInfo>
</Configuration>
</Extension>
</Render>
4. Save the RSReportserver.config file.
Note: Changing the rendering extension parameters only affects rendering operations on the Report Server.
When I access to Report Manager and export the report(includes a page header) to Excel format, the blank row will disappear now.

Pie Chart Only Displays the Data of the First Row of the Table
Hi Experts,
I have a problem that the pie chart will not change when click on a second row or other rows on the table. It only displays the data of the first row of the table. How can I set up to make it reflect on any rows when I click the table? Please help, and I would very appreciate that.
Thanks,
-DonThanks a lot for your response. I have realized that the pie chart behaves that way, so I just use the filter to see the specific data that I want. Also, you can drag the row and drop it right at the first row to see the data in the pie chart.

INSERTing a blank row in the result set
Hi friends,
SELECT * FROM EMPLOYEES ORDER BY DEPARTMENT_ID;
In the result of the above, I need to INSERT a blank row in the result for each DEPARTMENT_ID. i.e., the result should look like the following:
EMP_ID - NAME - SALARY - DEPARTMENT_ID
101 - Albert - 10,000 - 10
102 - Benjamin - 8,000 - 10
103 - Chitra - 10,500 - 20
104 - David - 4,500 - 20
105 - Elango - 6,000 - 20
106 - Fathima - 6,000 - 30
107 - Ganga - 9,000 - 30
etc.
I don't want to insert into the table. Just in display I need a blank row.
Thanks in advance.

How to set max. number of rows in a table?
Hi,
I'm working on a SCADA interface. In this application there are different tables with vertical scroll bar.
I prefer to make visible only the initialized rows (I've initialized 40 blank rows of a table with a string array). Since the window not contain all 40 rows but only 20 rows, I set the rows number of "table properties window" to 20; so I added a vertical scroll bar.
Now, when a user scroll the scroll-bar, he can view not only the 40 rows initializated, but an undefined number of rows.
There's a way to visualize only a limited number of rows?
Thanks in advance!duplicate

Korean characters are displayed as blank box on the TextField in Galaxy Note 3/Android 4.4/AIR 4.0
The AIR SDK we used is 1/14/2014 Release - AIR 4.
The device we have tested on is Samsung Galaxy Note 3/Android 4.4.
We found that it's quite similar with Bug 3681788 which has been fixed in Beta version 4.0.0.1619.
We checked the issue again with this beta version, and the result is Chinese characters are shown correctly, but Korean's are still not.
Bug 3681788: The CCJ languages characters are displayed as blank box on the TextField.
Hope it can be fixed as soon as possible.Japanese Characteres have same issue.
We tested on ASUS Nexus 7/Android 4.4.2/AIR 4.0 and Japanese characters are displayed as blank box in the TextField.
The AIR SDK we used is February 20th 2014 Release - AIR 4.
The device we have tested on is ASUS Nexus 7/Android 4.4.2.
AIR SDK 3.6 worked fine.
AIR SDK 3.9 has same issue.
We tested Chinese on ASUS Nexus 7/Android 4.4.2/AIR 4.0, and Chinese Characters are displayed as blank box in the TextField.
I doubt that Korean Characters will also displayed as blank box.( Sorry we cannot read or write Korean so we couldn't test it)
I am guessing GalaxyNote 3(4.4) may also have same issue with Japanese.
Hope this helps
