How to set a default integer value in a form

Question

I have a form defined as follows:
=================================================
public static class ProjectForm extends FormData
private int idx;
private String name;
private String projectNumber;
private String description;
public void setIdx(int index)
this.idx = idx;
public int getIdx(){
return this.idx;
public void setName(String name)
this.name = name;
public String getName()
return this.name;
public void setDescription(String description)
this.description = description;
public String getDescription()
return this.description;
public void setProjectNumber(String projectNumber)
this.projectNumber = projectNumber;
public String getProjectNumber()
return this.projectNumber;
======================================================
When I add a new entry into the database, I have no issues. However, when I want to modify an entry I run into some issues with the idx entry. For some reason, I cannot set a default value into the netui:label tag. My jsp code is as follows:
===================================================
<tr valign="top">
<td>
Index:
</td>
<td>
<netui:label value="{actionForm.idx}"
defaultValue="{pageFlow.project.idx}"/>
</td>
</tr>
<tr valign="top">
<td>
Name:
</td>
<td>
<netui:textBox dataSource="{actionForm.name}"
defaultValue="{pageFlow.project.name}"/>
</td>
</tr>
<tr valign="top">
<td>
ProjectNumber:
</td>
<td>
<netui:textBox dataSource="{actionForm.projectNumber}"
defaultValue="{pageFlow.project.projNum}"/>
</td>
<tr valign="top">
<td>
Description:
</td>
<td>
<netui:textBox dataSource="{actionForm.description}"
defaultValue="{pageFlow.project.description}"/>
</td>
</tr>
======================================================
The the project class is passes into the page and has the appropriate values. The name, project number and description fields work as I would expect. However, the idx value is alway '0'. If I print out pageFlow.project.idx it has the correct value.
How do I fix this? My feeling is that it is related to the form field being an int and not a string. The default parameter indicates that is only works with null values, and ints default to zero. Do I need to use an Integer value instead in the form, or just stay away from non-string form fields.
Thank for the help!!

In the action which displays the edit page just set the form idx value before displaying the jsp.
