Problem while saving values into variables in a Wizard Page

Hi everybody. This is my first post here.

As part of my project, I am building a plugin in Eclipse. It basically contains five Java files which extend the WizardPage class. There is another class which extends the Wizard class. I save the value of a textfield (e.g. username) in a public String variable. To save the value, I use a simple setter method(e.g setValue()) and I call it from the updatePageComplete() method. But, the problem arises when I try to access the stored value using a getter method(e.g. getValue()) . The getter method returns NULL.

Any Eclipse Plugin development guys around can help me please ?? It's urgent.

The code is kinda huge... so I didnt post it here... But, if anybody wants to take a look at the code, I could mail it. Just post your email-id if you want to take a look at the code..

Thanks.
