[upgrading <du...@yahoo.com>]

Hi

I have a problem with a grid, i did a custom grid in a Form when i sort the
grid there isn't problem but i use a button in my form after sorting grid
after i have an exception :

java.lang.NullPointerException
org.apache.tapestry5.corelib.components.Grid$DefaultGridSortModel.getSortConstraints(Grid.java:346) 
org.apache.tapestry5.corelib.components.Grid.setupDataSource(Grid.java:463) 

In my .java

// List to fill the grid
	@Persist
	private List<Users> listGrid;

public Object onActivate() {	
/***** fill list for the grid ****/
          listGrid = (List<Users>) userManager.findString("select u from
Users u inner join fetch u.role inner join fetch u.shop w");
}

        // sent list to the grid
	public List<Users> getList() {		
		return  (List<Users>) listGrid; 
	}

@SetupRender
	void initializeValue() { 
		i=((grid.getCurrentPage()-1) * (grid.getRowsPerPage())+1);
		// Grid model
		this.model = beanModelSource.createDisplayModel(Users.class,messages);
		this.model.add("shop",pcSource.create(Users.class,
"shop.shoCode")).sortable(false);
		this.model.add("role",pcSource.create(Users.class,
"role.rolDesignation")).sortable(false);
		this.model.add("count",null);
		this.model.add("remove",null);
		this.model.exclude("useDateCreat","useDateModif","useId","usePassword");
this.model.reorder("count","useReference","useFirstname","useName","useLogin","useEmail","shop","role","useActive","remove");
	}

tml page :

<t:grid t:id="grid" t:source="list" rowsPerPage="10" row="user"
t:model="beanModel">
		<t:parameter name="countCell">${getCount()}</t:parameter>
		<t:parameter name="useReferenceCell">
			 ${user.useReference} 
		</t:parameter>
		<t:parameter name="removeCell">
			<t:checkbox name="remove" id="remove" value="remove" />
		</t:parameter>
		<t:parameter name="shopCell">
			<t:if test="user.shop">
				${user.shop.shoCode}
			</t:if>
		</t:parameter>
		</t:grid>

Is somebody can help me to solve this problem? I have tried lot of
