How to iterate to create select box.
Hi,
I am trying to iterate through a vector to populate a select box.
I have a class CategoryList in application scope that holds a list of
Categories. Each category has a CategoryGroup name and a vector of
CategoryValues.
At run time I am trying to create a page that dynamically creates the above
select boxes not knowing how many elements will be in the list.
I can iterate through the CategoryGroupName via:
<logic:iterate id="category" name="CategoryList" property="categoryList"
scope="application">
<bean:write name="category" property="categoryGroup" filter="true"/>
<!--need to figure out how to create select box -->
</logic:iterate>
Any help in figuring this out is appreciated.
My category class is as follows:
public class pwCategory
{
private String categoryGroup;
private String categoryName;
private String categoryAbrv;
private int categoryNumber;
private String categoryValue;
java.util.Vector categoryValues;
public pwCategory()
{
}
public String getCategoryGroup()
{
return categoryGroup;
}
public void setCategoryGroup(String newCategoryGroup)
{
categoryGroup = newCategoryGroup;
}
public void setCategoryAbrv(String newCategoryAbrv)
{
categoryAbrv = newCategoryAbrv;
}
public String getCategoryAbrv()
{
return categoryAbrv;
}
public void setCategoryNumber(int newCategoryNumber)
{
categoryNumber = newCategoryNumber;
}
public int getCategoryNumber()
{
return categoryNumber;
}
public void setCategoryValue(String newCategoryValues)
{
categoryValue = newCategoryValues;
}
public String getCategoryValue()
{
return categoryValue;
}
public void setCategoryValues(java.util.Vector newCategoryValues)
{
categoryValues = newCategoryValues;
}
public java.util.Vector getCategoryValues()
{
return categoryValues;
}
}
My categoryList class is as follows:
import java.util.*;
import com.popware.avantis.*;
public class pwCategoryList
{
private List categoryList=new Vector();
public pwCategoryList()
{
}
public List getCategoryList()
{
return categoryList;
}
public void setCategoryList(List categoryList)
{
this.categoryList = categoryList;
}
public void addCategoryList(pwCategory newCategory)
{
categoryList.add(newCategory);
}
}
Regards
Alex

How is scope valid, the documentation says that scope is a valid tag
attribute, but looking at the IterateTag.java I could not find such an
attribute. Am I missing something?
