Edited by: user12171025 on Nov 4, 2009 11:11 PM
Hi,
I think that its necessaries to use AJaX.
I am implemeting something like that.
I have a input text that works like a filter and depends on what my user types in input text I populate my table with some information.
In order to do that, I put in my JSP a div with an Id and I used ajax, like that:
function ajaxFunction()
var xmlhttp;
if (window.XMLHttpRequest)
xmlhttp=new XMLHttpRequest();
else if (window.ActiveXObject)
// code for IE6, IE5
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
else
alert("Your browser does not support XMLHTTP!");
xmlhttp.onreadystatechange=function()
if( xmlhttp.readyState==4 )
document.getElementById("tabelaResponsaveis").innerHTML = xmlhttp.responseText;
var resp = "<f:invokeUrl var='solicitacao' methodName='getResponsaveis'/>";
xmlhttp.open("POST",resp,true);
xmlhttp.send(null);
getResponsaveis is a method inside my BPM that returns a HTML code (the table HTML code with all the information that I need to show.
I Hope to help
Thanks Marcos

How to display negative values in a screen field of a screen
Hi All,
Please let me know how to display negative values in a screen field of a screen.
thanksHi Kishore,
You can do this method. In the screen , create a text field of CHAR instead fo creating an INT4 field.
I have created a field of CHAR of name say TEXT.
In the main program,
declare a variable of the same name ie. TEXT.
data: TEXT(5) TYPE C.
In PBO, just assign the negative values.
It will work.Since there is automatic conversion between character and integer data types, it will work for positive values as well.

Sylendra. -
Display Key Values only on filter screen
Hello all,
I have one specific requirement. When user runes any query (based on an infoset) , data is displayed. After which if user presses right clicks on data filed -> Select filter value. Then one Filter screen is displayed. Values from this filter screen are displayed as text values.
I want it to display as key value. This particular infoobject is in coumpounding.
I have already tried changing Bex properties at infoobject level and RSD1, it does not have any effect.
can anyone suggest any option.
Edited by: priyanka s on Sep 15, 2008 10:41 AMHi Priyanka,
In BI 7.0, these options are available in the definition of InfoProvider itself.
For DSO:
Right Click on Key/Data Fields --> Provider Specific Properties of the InfoObject --> Display (Column)
For Cube:
Right click on Dimensions --> Provider Specific Properties of the InfoObject --> Display (Column)
Set the required properties here and you will get the required results.
Hope this time you get it right

How do I display array values in a text field?
Hi there-
I have a small Flash movie I'm trying to complete, it's my
first go around with Flash 8 so I appreciate your patience:
I built an array with some actionscript which seems to work
fine (I can trace it and all is well in the trace window). Now I'm
simply trying to display it to my Flash movie screen and I've built
a dynamic text window which is working, except that I only ever get
the last array element to appear in the dynamic text window. I've
traced the code and see all of my array values, but when I use
"myResults_txt.text=picker_array;" I only see the last position's
value in my array. I tried playing with the "multiline" attribute
for the text field, it didn't seem to make any difference.
I'm sure it's probably something silly that I've missed, but
how do you display an array, with all of it's values to a dynamic
text field (I even tried using the textArea component but ran into
the same problem).
Thanks in advance for any help-
richThanks for your input. I tried just about everything but
ended up re-writing the contents of the array to a var and looping
through the var. Not my first choice but it got me to done.
Thanks again,

Is there any templates, or code, that could guide me as to how to transfer the table to jsp.
thanks,
sunilHi Sunil,
The code from bean class is here,
public void listDetails(String releaseGroup,String releaseCode)
throws Exception
try
if (mRepository == null )
System.out.println("NuLL");
try
IFunctionTemplate ft=mRepository.getFunctionTemplate("BAPI_REQUISITION_GETITEMSREL");
myFunction=ft.getFunction();
catch (Exception ex)
throw new Exception(ex + "Problem retrieving JCO.Function object.");
if (myFunction == null)
System.exit(1);
mConnection.execute(myFunction);
JCO.ParameterList input = myFunction.getImportParameterList();
input.setValue(releaseGroup,"REL_GROUP");
input.setValue(releaseCode,"REL_CODE");
input.setValue(releaseFlag,"ITEMS_FOR_RELEASE");
System.out.println("Imported");
catch (Exception ex)
ex.printStackTrace();
System.exit(1);
mConnection.execute(myFunction);
JCO.Table codes = null;
codes =myFunction.getTableParameterList().getTable("REQUISITION_ITEMS");
size =codes.getNumRows();
if (size == 0)
System.out.println("No value matches the selection cretaria");
purchaseRequisitionNo = new String[size];
item = new String[size];
requestorName = new String[size];
description = new String[size];
creatorName = new String[size];
purchaseRequisitionDate = new String[size];
plant = new String[size];
// getter methods
public int getSize() { return size; }
public String getPurchaseRequisitionNo(int i){return purchaseRequisitionNo<i>; }
public String getItem(int i) { return item<i>; }
public String getDescription(int i) { return description<i>; }
public String getCreatorName(int i) { return creatorName<i>; }
public String getPurchaseRequisitionDate(int i)
{return purchaseRequisitionDate<i>; }
public String getplant(int i) { return plant<i>; }
Now in the JSP page get the number of entries in the table and try to get row by row from the bean class using the row number.
<%
int count = PR.getSize() ; // This method will return the number of
rows in the table.
for ( int i = 0; i < count ; i++ ) {
%>
<TR><TD ALIGN = "center"><%= PR.getPurchaseRequisitionNo(i) %> </TD>
<TD ALIGN = "center"><%= PR.getItem(i) %> </TD>
<TD ALIGN = "center"><%= PR.getDescription(i) %></TD>
<TD ALIGN = "center"><%= PR.getCreatorName(i)%> </TD>
<TD ALIGN = "center"><%= PR.getPurchaseRequisitionDate(i)%> </TD>
<TD ALIGN = "center"><%= PR.getplant(i)%> </TD>
<% } %>
Hope this is a simple way to get your requirement.
Let me know if this does not help you.

My guess is this bit here:
if(rsq.next()){
for (int i=0;i<name.length;i++) {
name = rsq.getString("name1");
rsq.next();
}I don't think your name array has been initialised in this file. Plus it assumes that the name array has exactly the same number of items as the query returns. To me thats rather dubious...
I would suggest this instead
while (rsq.next()){
name = rsq.getString("name");
}I'm still not entirely certain what you are trying to accomplish, but thats probably the cause of the null pointer.
good luck,
