Getting result of stored functions in UCM components

Question

Hi,
I have to create UCM component that executes function stored in DB and somehow "inject" it's return value to iDoc.
How can I get return value of DB stored function?
I managed to run the function, but I can not get it's return value.
The only documentation I found is inside "documentation" folder from HowToComponents bundle, but there is no even javadoc for executeCallable that returns CallableResults.
The queries I used are:
{ ? = call package.func(?) }
or
BEGIN ? := package.func(?); END;
I added 2 parameters to these queries ( in queries html file)
In both cases the function gets executed (I see changes in DB)
after the execution I try to getInteger("param1_name") on returned CallableResults and recieve NullPointerException:
Runtime error: java.lang.NullPointerException
at oracle.jdbc.driver.OracleCallableStatement.getInt(OracleCallableStatement.java:1119)
at intradoc.jdbc.JdbcCallableResults.getData(JdbcCallableResults.java:203)
at intradoc.jdbc.JdbcCallableResults.getInteger(JdbcCallableResults.java:98)
at DatabaseProvider.DatabaseProviderHandler.executeReservation(DatabaseProviderHandler.java:224) <------ calling getInteger("param1_name")
the param1_name is not changed in iDoc.
Thanks.

Hi,
you can do this with just one script object.
For example the "MyTexts" script object with the string variables and a function to return the values.
var infotext1 = "Lorem ipsum dolor sit amet"
var infotext2 = "Non eram nescius Brute cum"
function getText(FieldNumber) {
          return eval("infotext" + FieldNumber);
To populate a field you can call the function in the script object with an argument, which is the alias for the varaible number you want to return.
You don't need to enter the full somExpression to your script object, the name is enough.
Textfeld1.rawValue = MyTexts.getText(1);
