SPEL not giving desired result

Question

Hi ALL,
SPEL
*${oa.TestPVO1.xxDisable}* on Disable Property for a button
In CO
OAApplicationModule am = (OAApplicationModule)pageContext.getApplicationModule(webBean);
am.invokeMethod("hide");
In AM
public void hide()
OAViewObject disvo = (OAViewObject)getTestPVO1();
if (!disvo.isPreparedForExecution())
disvo.executeQuery();
Row drow = disvo.createRow();//.getCurrentRow();
disvo.insertRow(drow);
drow.setAttribute("xxDisable", Boolean.FALSE);
NOT giving desired o/p to disable the button
Thanks,
Sombit.

Try assigning the SPEL value in the *VORowImpl.
First, in order to assign a value to SPEL, you'll need to create a custom VO. Here's a sample query I've used to create my VO to pull data pertainining to if an Attribute should be mandatory/rendered.
SELECT min(descriptive_flex_context_code) descriptive_flex_context_code, min(Enabled) Enabled, min(END_USER_COLUMN_NAME) END_USER_COLUMN_NAME, min(required_flag) required_flag, min(application_column_name) application_column_name,
min(xxx.LOV) LOV
from
(SELECT descriptive_flex_context_code,'Y' Enabled, END_USER_COLUMN_NAME, required_flag, application_column_name,
decode(ffvv.flex_value,null,'N','Y') LOV
FROM FND_DESCR_FLEX_COL_USAGE_VL fdfc,
fnd_flex_values_vl ffvv
WHERE (fdfc.APPLICATION_ID=20045)
and (fdfc.DESCRIPTIVE_FLEXFIELD_NAME LIKE 'SPL Account Map')
and fdfc.enabled_flag = 'Y'
and fdfc.display_flag = 'Y'
and fdfc.application_column_name = 'ATTRIBUTE5'
and ffvv.flex_value_set_id(+) = fdfc.flex_value_set_id
and rownum = 1) xxx
Once the VO is created, I created several transient "boolean" attributes in my VO. These attributes will be assigned a value based on code I place in my *VORowImpl since this is the file which controls attribute assignments.
But before that, in my *VOImpl, I've defined a custom method which is used to execute the VO from my AM.
public class Ref5PVOImpl extends OAViewObjectImpl
* This is the default constructor (do not remove)
public Ref5PVOImpl()
public void initRef5PVO()
// setWhereClause("descriptive_flex_context_code in (select vendor_name from spl_account_map where cont_cd = :1)");
setWhereClauseParams(null); //Always reset
// setWhereClauseParam(0, acct);
// System.out.println("value_selected customer>> "+acct);
executeQuery();
In my *VORowImpl, I've added custom code to my Attribute methods so that they return the proper values when invoked...
public String getMakeRequired()
if (getRequiredFlag()!= null)
if ("Y".equals(getRequiredFlag()))
//if(getMessageChoiceAttribute()==null)
System.out.println("Required returned yes");
return "yes";
else
System.out.println("Required returned no");
return "no";
else
return "no"; //poplist will be disabled - DFF is not configured
public Boolean getOptionRender()
if (getLov()!= null)
// In this method check if the Message Text Input is valid
if ("N".equals(getLov()))
System.out.println("OptionRender returned true "+ getLov());
return Boolean.TRUE; //text input will be enabled if no LOV exists
else
System.out.println("OptionRender returned false "+ getLov());
return Boolean.FALSE; //text input will be disabled if LOV exists
else
return Boolean.FALSE; //text input will be disabled - DFF is not configured
Then add your SPEL directive into your field's Property inpector...
${oa.Ref5PVO1.MakeRequired}
${oa.Ref5PVO1.OptionRender}
