Af:inputText is not shown when its corresponding value in the view Object i

Question

Hello all,
I'm new to ADF and I need some help on this issue.
I've a dropdown field and series of text fields in my form. All these fields represents the corresponding ViewObject attributes. The values of text fields are dependent on the dropdown selection.
I've written a valueChangeListener which works fine.
The problem is, if the viewobject values (database values) for the corresponding text fields are null then the inputText disappears. But I wanted to show the inputText with emplty string. Any help on this issue pls.
Regards,

code in my jspx:
<af:selectOneChoice value="#{bindings.BannerTextView1PagegroupName.inputValue}"
label="#{bindings.BannerTextView1PagegroupName.label}"
binding="#{backing_BannerTextDorpDownUpdate.selectOneChoice1}"
id="selectOneChoice1" autoSubmit="false"
valuePassThru="true"
onchange="this.form.submit()" valueChangeListener="#{backing_BannerTextDorpDownUpdate.newItemCodeChanged}">
<f:selectItems value="#{bindings.BannerTextView1PagegroupName.items}"
binding="#{backing_BannerTextDorpDownUpdate.selectItems1}"
id="selectItems1"/>
</af:selectOneChoice>
<af:inputText value="#{bindings.BannerTextView1BottomHeadingLarge.inputValue}"
simple="true"
required="#{bindings.BannerTextView1BottomHeadingLarge.mandatory}"
columns="#{bindings.BannerTextView1BottomHeadingLarge.displayWidth}"
binding="#{backing_BannerTextDorpDownUpdate.inputText1}"
id="inputText1">
<af:validator binding="#{bindings.BannerTextView1BottomHeadingLarge.validator}"/>
</af:inputText>
valueChangeListner in my backing bean:
public void newItemCodeChanged(ValueChangeEvent valueChangeEvent) {
List vObject = (List)project1.backing.JSFUtils.resolveExpression(FacesContext.getCurrentInstance(),"#{bindings.BannerTextView1PagegroupName.items}");
System.out.println("JSFUtil test......"+vObject);
SelectItem vItem = (SelectItem)vObject.get(Integer.valueOf((String)valueChangeEvent.getNewValue()));
..... my business logic code
I've created association and view link for changing the values on dropdown selection. Its just the association of primary keys of the 2 tables which I use for the fields in the form.
