Commanbutton submit issue...

Question

I am new to ADF, using ADF (Jdev) 11g
I am working on a jsff page which is embedded in a taskflow, this shows up in a dynamic region... based on a command button action call, a method is invoked in the backing bean.
The problem i am facing here is when i click the command button, the action call invokes some method in the backing bean where i print all the values entered in the inputtext box. But when i print out those in the method, i get null printed.. Can anyone please let me know what am i missing here, please find the code as mentioned below???
Please refer the code as mentioned below
<af:panelFormLayout labelWidth="150px" fieldWidth="200px">
<af:inputText label="one" id="p_one" value="#{upgradeMaster.jdbcDriver}" />
<af:inputText label="two" id="p_two" value="#{upgradeMaster.jdbcUrl}" />
<af:inputText label="three" id="p_three" value="#{upgradeMaster.jdbcLogin}"/>
<af:inputText label="four" secret="true" id="p_four" value="#{upgradeMaster.jdbcPassword}"/>

UpgradeMasterBean.java  ( this has all the getter and setter methods of different variables like jdbcDriver.. etc. )
private String jdbcDriver;

this.jdbcDriver = jdbcDriver;
public String getJdbcDriver() {
return jdbcDriver;
public void upgradeMasterRepository()
System.out.println("jdbcDriver " + jdbcDriver);
System.out.println("jdbcUrl " + jdbcUrl);

System.out.println("jdbcDriver " + jdbcDriver);
System.out.println("jdbcUrl " + jdbcUrl);
System.out.println("jdbcLogin " + jdbcLogin);
System.out.println("jdbcPassword " + jdbcPassword );
this.outputMessage = "failure";
}

Hi,
if you have a dynamic region, try setting the scope of the managed bean to view scope so its larger than request. For this however the managed bean must be defined in the Task Flow definition since view scope is not an option for faces-config.xml
Note that beans that perform JDBC access should not be in request scope if you expect your application to scale
