How to assign a value of the bean to a js variable.

Hi,
Im getting some values from the DB which is stored in a list , Now the list is sent across to the jsp through the bean.
I need to get the length of the list
I tried something like this.
<script>
var size = <% rmaLicenseTransferForm.slfextUiElements.size(); %>
</script>rmaLicenseTransferForm is the name of the formBean and slfextUiElements is the name of the list.
I guess this wont work....by the way i using struts framework.....
Thanks

Use the JSTL fn:length tag.

How to assign a value to the viewcriteria attribute from backing bean ?

Hi,
I have a readonly VO with the following query
select attr1,attr2, attr3, attr4
from sometable
I have a view criteria in the above VO something like
attr1=
and attr2=
I have dragged and dropped this criteria on a Status.jsff page as query panel with table. So the user can search the records by manually entering the values in the query panel. Also, there is another page Main.jsff where, if the user clicks on a button, it redirects him to Status.jsff page carrying a numeric value from the Main.jsff page. Now I have to assign this numeric value to "attr1" of the view criteria and execute this VO and show the updated results in the Status.jsff page.
I used the below code :
ViewObject vo = appModule.findViewObject("VOName");
ViewCriteria criteria = vo.getViewCriteriaManager().getViewCriteria("CriteriaName");
criteria.getVariableManager().setVariableValue("attr1", numericValue);
vo.applyViewCriteria(criteria);
vo.executeQuery();
For the above code, i got an error saying that Variable "attr1" not defined in "VOName"
Then i tried setting simple where clause
vo.setWhereClause("attr1="+numericValue);
vo.executeQuery();
For this code, i got an error saying that SQL error during statement preparation.Statement: SELECT * FROM (select attr1 ,attr2,attr3,attr4,from VOName) QRSLT WHERE (attr1=1234)
Please let me know the solution to this problem.

Thank you all for the suggestions.
The idea of Bind Variable works to query the criteria. But I have a Status.jsff page where User can even manually enter the attr1 value and query the results. When I added a bind variable to my VO, one extra input text field with the Bind variable name got added to the query panel in Status.jsff page. Also the table in the page did not show any results even after performing the executeQuery() on the VO(as per the steps explained in the Andrejus blog link that Navneeth has provided)
Please suggest

How to assign a value to the page variable to enable partial page rendering

This is part of my code:
<bc4j:rootAppModuleScope name="App1"
rendered="on@ctrl:page">
Now, I want to change the value of "on@ctrl:page" to "true" after user click a button so that part of the page will be displayed. But how do I assign the value to "on@ctrl:page". I tried to put the followings in my even handler:
<bc4j:setPageProperty name="on" value="true">
<bc4j:parameter name="on" />
</bc4j:setPageProperty>
But it doesn't work. Could someone pls tell me how I should do it.
Thanks a lot!
Ling

You should do is:
in your event handle codes,you add the list:
public static EventResult eventname(
BajaContext context,
Page page,
PageEvent event) throws Throwable
EventResult result = new EventResult(page);
result.setProperty("on","true");//or "false"
return result;
then,
change
rendered="on@ctrl:page" -> data:rendered="on@ctrl:eventResult"
also ,you should see the 5th part of 'UIX Developer's Help'

How to map AM method return values in the bean

Hello -
I have this requirement to map AM method return values in the bean as explained below. Please suggest a solution.
Scenario: I am calling an AM method, which returns a String object on page load.
AMImpl Method-
public String getProfileName (){
return "Profile";
I wish to catch this retun value in the Bean Variable on page Load. I have created a methodAction biding on page and invokeAction to call this method on Page Load, but I don't know how to catch this value in the bean. Please suggest how to achieve this. Also, I need to achieve this in jsp page. I can't use TaskFlow for this.
I am using ADF 11g.

Rohit

Hi, I think there are two ways, from the data control drag n drop the methods return value to the page. This way a binding for that will be created at the page definition eg retVal.
and in the backing bean you can access it by calling resolveExpression("#{bindings.retVal.inputValue}")
You can also call your method directly from the backbean
((YourAppModuleImpl) getBindings().getDataControl().getApplicationModule()).yourMethod();
public DCBindingContainer getBindings() {
return (DCBindingContainer) resolveExpression("#{bindings}");
I dont know if the second method suits you

I want to do this to print two documents(values) with a single command (parameter)
Anybody please help quickly,
Now, I have 2 tables from different queries. I have a print (HTML written) option in my WEB Template

Please help.
THANX A LOT,

Hi,
Try assigning two values seperated by a delimiter ( say '|') to the same parameter.
In the function get the parameter value and seperate the values using the same delimiter.
<param name="QUERY" value="REPORT_TEST1|REPORT_TEST2"/>

How do you assign a value to the APEX field APP_USER

Application Express 4.0.2.00.07
Hi
Is there a special function/procedure to assign a value to the APP_USER field
or a simple APP_USER := :P1_LOGIN_NAME would do
Z

Hello Zac,
>> or a simple APP_USER := :P1_LOGIN_NAME would do
The APEX engine is already doing it for you after a successful login – setting the value of APP_USER as the user login name. You can use it as a substitution string or with the bind variable notation (:APP_USER).

How to assigne multiple value in key of read table

Hi gurus,
I want read table xxxx with key field1 = ' xxx' or field1 = 'yyy'.
how to assign multiple value as key for the same field while reading internal table.
Regards
sagar

Hi ,
You can loop the internal table like
loop at <table xxxx> where field1 = ' xxx' or field1 = 'yyy'
or you can write two read statements to read the internal table in wrk area.
read table <table xxxx> with key field1 = ' xxx'.
if sy-subrc <>0
read table <table xxxx> with key field1 = 'yyy'.
if sy-subrc = 0
endif.
else.
do your data processing.

Thanks,
I have added scope="application". It still show "null" indicating that the bean is not initialized with the properties. I would like a quicker way to initialize a bean property than invoking the setProperty tag for each property.
Here is a simple example that demonstrates the problem:
<%@ page language="java" %>
<%@ page import="com.tests.*" %>
<jsp:useBean id="monBean" class="com.tests.MonBean" scope="application"/>
<%
MonBean mb = new MonBean();
mb.setName("toto");
monBean= mb;
%>
<html>
<head>
<title>Lomboz JSP</title>
</head>
<body bgcolor="#FFFFFF">
<jsp:getProperty name="monBean" property="name"/>
</body>
</html>And the bean
package com.tests;
public class MonBean {
private String name;
public String getName() {
     return name;
public void setName(String name) {
     this.name = name;
}This show "null".
Any other idea why this is not working?
Thanks,

How to assign a value for Unit of measure (like PC, KG...) in ABAP program?

Hi,
    How to assign a value for Unit of measure (like PC, KG...) in ABAP program?
    I want to assign PC in a field to execute the program, like wa-ENTRY_UOM = 'pc'.
    But the system returen a message that "Unit of measure is not convertible to stockkeeping unit PC"
    Could anyone tell me how to assign the value??
    Thanks!

hi,
first convert the quantity in the same unit ( like in you case ST to PC ) by using FM :    MD_CONVERT_MATERIAL_UNIT
CALL FUNCTION 'MD_CONVERT_MATERIAL_UNIT'
    EXPORTING
      i_matnr                    = matnr
      i_in_me                    = entry_uom
      i_out_me                   = out_uom
      i_menge                    = quantity
   IMPORTING
     E_MENGE                     = fp_l_v_quant
   EXCEPTIONS
     ERROR_IN_APPLICATION       = 1
     ERROR                      = 2
     OTHERS                     = 3.
IF sy-subrc <> 0.
          give error message here
   ENDIF.
bcoz in ur program somewhere the quantities etc are compared and there units may be different... so that is why it is showing such error. so just convert convert the quantity in the same unit .

How to assign a value to a parameter {?MyParam} dynamically?

How to assign a value to a parameter {?MyParam} dynamically?
Example:
{?One_Or_Two} <- my first parameter
{?MyParam}       <- My second parameter
The Code:
If ( {?One_Or_Two} = 'One' then
    {?MyParam} = 'One' ;
else
    {?MyParam} = 'Two' ;
(THIS IS NOT WORKING FOR ME! ANYONE KNOW WHY?)
IT NEVER ASSIGN THE VALUE?
My Command query looks like:
SELECT * FROM MyTable
    WHERE MyTable.MyColumn = {?MyParam}
THANKS

Hi Joseph,
I'm a bit unclear as to what you are doing and from what I see you're running in circles.
Your Command query is looking for a field that is equal to {?MyParam}.
Now you want to take {?MyParam} in the report and change the value after you've set it.
Parameters cannot be set from the Command, you can format it and manipulate it but they cannot be set except from the parameters window or from a front-end.
Thanks,
Brian

and also I am able to handle multiple values the in the query by using IN :Parameter, but seems when we select more than one value from the parameter drop down i think the Bi Publisher is sending the values in concatenated form something ilke
ex: "'ACCOUNT','HR','SALES'" ,and when trying to display the parameters values in the output, its throwing the error as 'missing right paranthesis' ....on the whole do you have any solution which would handle
1.Single selection.
2.Multiple selection.
3.'ALL' Values.
4.Separating the concatenated string into individual strings and dispaly them on the output of the report..etc..in case of Mulitple selection.
Ex:
Concatenated String from BI Publisher:"'ACCOUNT','HR','SALES'"
Expected Output on the report:ACCOUNT,HR,SALES
reply to this would be much appreciated....
thanks,
manoj
