Possible to default the value displayed in a dropdown?

My form has several drop down list boxes which I prefill in WDA with values - specifically, Project Manager name.
When I go in to my form, I can select any one and Submit back to the backend. the data is saved appropriately.
When I go in Change Mode, I select the data from the backend to display in my form, but those names do not populate in my drop down fields.
I know this is possible, because there are a few other drop down boxes that do come back pre-filled.
The only difference between the dropdown boxes that do work and those that don't is that the ones that do work have static values defined in the form while the others have values populated dynamically from the web dynpro and passed in to the form.
any ideas?
thanks,
rp.

EDIT.. I fixed this by passing the drop down VALUE to the form instead of the actual TEXT.
for instance, my manager's id was 12345 but I passed John Doe.
passing 12345 chose the correct TEXT to display.

Hi
Use the link below and download the documentation
http://www.oracle.com/technology/documentation/bi_ee.html
I think you will find what you are looking for in the Answers, Delivers, and Interactive Dashboards User Guide, but in short the syntax to display a variable value is as follows:
As shown above the syntax for using a presentation variable is:
@{variablename}{defaultvalue}
For Session variables use:
@{biServer.variables['NQ_SESSION.variablename']}
For repository variables use:
@{biServer.variables['variablename']}

Is it possible to use the value of a string to reference a component in the

I'm fairly new to Java so this may be a stupid question!
Is it possible to use the value of a string to reference a component in the code? For example in the code below, Wall is a class holding 3 different arrays. The Robot class has an array called finishBricks. When the buildWall method is run it receives the integers width and height which are used to construct the dimensions string. I want to use this string to then load the appropriate Wall array into the finishBricks array.
I hope this makes sense! Any help would be greatly appreciated!
class Robot {
public double[][] finishBricks;
public void buildWall(int width, int height) {
Wall w = new Wall();
String dimensions = "Wall" width "x" +height;
this.finishBricks = w.xxxx; // where xxxx is replaced by whatever the String dimensions is
class Wall {
     public double[][] Wall4x2 = {
          {-30.00,-01.60,27.45},
          {-30.00,-06.75,27.45},

How do I default the value in an LOV?

Dear experts,
What I am trying to achieve is changing the default value in an LOV, based on the value of another field. I have an LOV that lists employee names. There is another field, an account number, which when selected is used to determine the default employee set against this account. This employee I want to use to add into the LOV as a default the value, before the user selects a value in the LOV. The user can still invoke the LOV and search for a different employee, but the functionality I am concered with is setting this default employee.
I have modified the ProcessForm in the associated controller class. I have obtained the account number and using an SQL query I have obtained the default employer, but I can not seem to set this value in the LOV as a default. Does any one have any ideas?
For the LOV there are two criteria values in the LOV mapping, the org id and the code combination id, both used in the query to get the default employee.
Many thanks for your assistance in advance.
Mark

Hi,
IF want use dependent lov ..then refer below link..
http://oracleanil.blogspot.com/2010/12/dependent-lov-in-oaf.html

&& ("lovUpdate".equals(pageConext.getParameter(EVENT_PARAM))
|| "lovValidate".equals(pageConext.getParameter(EVENT_PARAM))))

I want system to be defaulted the value that I keyed in the parameter. How to do that ?

Lim

Hi Lim
Are you using Discoverer Plus?
If so, there is a preference in pref.txt that controls whether the parameter values are saved with the workbook. It is called SaveLastUsedParamValue. This has two settings as follows:
0 - Use the default value as set by the report writer
1 - Save the value the user just entered and use that as the default the next time
Best wishes

Is it possible to change the value of "maxdatafiles" after creating a db??

Hi Chris,
Thanks for updating that but here's what in Oracle Doc:
From Oracle Documentation (Oracle® Database New Features Guide 10g Release 2 (10.2))
Eliminate Control File Re-Creation
With the control file enhancements, there is no longer a requirement to re-create the control file when changes in the configuration parameters are made. These include the MAXLOGFILE, MAXLOGMEMBERS, MAXLOGHISTORY, MAXDATAFILES, and MAXINSTANCES parameters.
This feature eliminates database downtime when a configuration parameter change is made in the control file

When the combobox is rendered all the values displayed look like [object Object].

I wasn't sure where to post this so please forgive me.
I am trying to populate a combobox with a series of values
returned from a Coldfusion method that retrives a resault froma
database. Basically all the data from a table of staff.
<cffunction name="getUsers" access="remote"
returntype="array">
<cfquery name="q" datasource="#datasource#">
SELECT *
FROM STAFF_CHARTS_STAFF_TEMP
</cfquery>
<cfset aRecordset= querytoarray(q)>
<cfset flash.result=aRecordset>
<cfreturn flash.result>
</cffunction>
<cffunction name="querytoarray" returntype="array"
output="No">
<cfargument name="q" required="Yes" type="query">
<cfset var aTmp = arraynew(1)>
<cfif q.recordcount>
<cfloop query="q">
<cfset stTmp = structNew()>
<cfloop list="#lcase(q.columnlist)#" index="col">
<cfset stTmp[col] = q[col][currentRow]>
</cfloop>
<cfset arrayAppend(aTmp,stTmp)>
</cfloop>
<cfelse>
<cfset stTmp = structNew()>
<cfloop list="#lcase(q.columnlist)#" index="col">
<cfset stTmp[col] = "">
</cfloop>
<cfset arrayAppend(aTmp,stTmp)>
</cfif>
<cfreturn aTmp>
</cffunction>
The result from a call of CF method getUsers is set as the
data provider to ComboBox with id = "cb"
<mx:RemoteObject
id="myService"
destination="ColdFusion"
source="staff_ratings.staff_Ratings-debug.staff"
showBusyCursor="true">
<mx:method name="getUsers" result="handleResult(event)"
fault="Alert.show(event.fault.message)"/>
</mx:RemoteObject>
<mx:Script>
<![CDATA[
import mx.rpc.events.ResultEvent;
import mx.controls.Alert;
[Bindable]
public var sResult:Array;
public function handleResult(event:ResultEvent):void{
sResult=event.result as Array;
cb.dataProvider=sResult;
]]>
</mx:Script>
However when the combobox is rendered all the values
displayed look like [object Object].
I think the problem is that the result is a array of arrays
so I need to find away to ectract a particular colun of data into
the combobox
How do I fix this?

This is what I did for a single field.
If you were wanting the to have muliple fields in the
dropdown, I would concatenate them in the query.
something like
select fname + ' ' + lname + ' ' + anotherfield as tech from
dbo.table
<cffunction name="getTech" output="no" access="remote"
returntype="query">
<cfset var qTech="">
<cfquery name="qTech" datasource="datasource">
select tech
from dbo.table
group by tech
order by tech
</cfquery>
<cfreturn qTech>
</cffunction>
<mx:RemoteObject
id="dataManager"
showBusyCursor="true"
destination="ColdFusion"
source="cust.components.cfgenerated.Records">
<mx:method name="getMasterQuery"
result="getMasterQuery_result(event)" fault="server_fault(event)"
/>
<mx:method name="deleteItem"
result="deleteItem_result(event)" fault="server_fault(event)" />
</mx:RemoteObject>
<mx:ComboBox id="TECH"
dataProvider="{dataManager.getTech.lastResult}" labelField="tech"
/>

Customer pricing procedure is picklist(dropdown). I could not default the value in drop down.
please suggest me step by step how to default customer pricing procedure in Account section web ui 2007.
Thanks

Dear Smita,
Thanks for your reply. The fact is that if I could default it in the screen text box then it would autometically goes to the corresponding table at save event.
So could you help me to identify the event by which one can keep default values in screen.
May be ISDAT or ISSTA event to default the valuesfor BP.
I have done to some extent for the fields belonging to BUT000 with the help of FM BUP_BUPA_FIELDVALUES_SET. I have placed a Z FM in ISDAT event. But the problem lies with the fields belonging to other tables.
Waiting for your update.

By using personalization can we default the values as null in oaf

Hi All,
Can we change the default values to null....
Actually i have from and to date fields....when ever page opens the vales are geting defaulting in that fields...
I need to make this as null....by using personalization is it possible( if yes...need help) or i need to extend the co..
Regards
Harry

Hi Harry,
If the values are defaulting from the "initial value" property it can be set to null by removing those values from personalization, but I feel it will be defaulting from code if it is so, same can not be achieved by personalization.

Where it is possible to change the value separator in Custom Field?

Hello,
This is a question around the "Custom Fields" and "Lookup Table"
I linked a "Custom Field" to a "Lookup Table".
I select the option "Allow multiple values to be selected from lookup table"
When I used this "Custom Field" in a view, the selected values are separated by a comma ",".
Where it is possible to change this value?
I saw another project server where the character is a semi-column ";" and I would like to test with ";".
Thank you in advance

Hi,
This will be triggered by your regional settings.
Hope this helps,
Guillaume Rouyre, MBA, MVP, P-Seller |
Hello,
Thank you for the answer.
Do you mean the "local regional settings"?
Because, depending on the PWA site I'm connected to I don't have the same values. I'm obviously using the same workstation.

Is it possible to change the values of fields In Me21n tansaction?

I Have to put in some logic to change the values of already existing Shipping condition field in the SHIPPING subscreen at the Line item level in ME21n transaction.
I searched for the user exit to do soo. Did not find anything to do this. I would like to know if it is possible through some other way.
thanks
shubha

Hi Shubha!
You might use BAPI_PO_CHANGE. Even if there would be a user exit / BADI, then execution is not sure.
You said: 'already existing shipping field' -> exits of a transaction are only executed during maintenance, not afterwards.
So maybe you have to make your changes completely outside of PO.
Still have a look at BADI ME_PROCESS_PO_CUST, there are a lot of methods and one might help you.

Christian
