Trying to bind request parameters to nested object with spring controller using the dot notation and I keep getting a bad request error

Question

I have searched and everything seems to say as long as you use spring 4+ I should be able to use dot notation to bind request parameters to a pojo.

This is what my request looks like:

And this is what my controller looks like:

And my dto:

I even tried adding @RequestParam("p.page") int page in the controller to make sure my endpoint was getting hit and it does. Am I missing something obvious or am I not allowed to use dot notation to populate a pojo with a spring controller?

And the parent class:

public class JhmPageableDto
{
    private String query;
    private int page;
    private int size;
    private String sort;
    private boolean sortAsc;
    
    public String getQuery()
    {
        return query;
    }
    
    public void setQuery(String query)
    {
        this.query = query;
    }
    
    public int getPage()
    {
        return page;
    }
    
    public void setPage(int page)
    {
        this.page = page;
    }
    
    public int getSize()
    {
        return size;
    }
    
    public void setSize(int size)
    {
        this.size = size;
    }
    
    public String getSort()
    {
        return sort;
    }
    
    public void setSort(String sort)
    {
        this.sort = sort;
    }
    
    public boolean isSortAsc()
    {
        return sortAsc;
    }
    
    public void setSortAsc(boolean sortAsc)
    {
        this.sortAsc = sortAsc;
    }
    
}
