Mixing parameters from component and page

[o1550762 <o1...@rtrtr.com>]

I have one component named PartofAddition.java and in it I have the following

public class PartOfAddition{
@Property
private int number;

@Property
private int picture;

public int getNumber()
{
 return number;
}

public int getPicture()
{
 return picture;
}
}
//PartOfAddition.tml

<div class="section">
<div class="post_number><label>${message:number}: </label><input
t:type="int" t:id="number" t:validate="required" size="4"></input></div>

<div class="post_number><label>${message:picture}: </label><input
t:type="TextField" t:id="picture" t:validate="required"
size="4"></input></div>


and page in which I try to call this component and along with some of the
fields declared in it and in PartOfAddition file, to compute some method.

public class ComputeAddition.java

@InjectComponent
private PartOfAddition partOfAddition;

@Parameter
private int number2;

public int computeIt(){
*//return addition of the two numbers, one from this page, and another from
the component PartOfAddition*
}


I have no idea how to implement this bolded. Any help is greatly
appreciated. Thanks in advance.
}

In Tapestry, components and pages are supposed to be a black box, so doing  
something that involves a field from one page and a field from one  
component is bad practice. I would put the calculation inside the  
component.
