Tapestry5 - Grid with variable "row" type
Hi,
I have a page where i load a list of objects depending on some other
variables. This list of objects can be of the type of 1 of several type of
entity objects.
So I have declared it as :
private List tableData;
and
t:grid source="tableData" ...
This works, but the problem is when defining the "row" attribute, I can't
use a variable of type "Object", as I won't be able to use this as needed.
Each type of object has the same property "action", but when trying to
access it as:
private Object row;
and
${row.action}
--> Object does not have this property
I understand that this won't work, but is there anyone who has an idea how I
can solve my problem or if this even will be possible?
I just wanted to make the grid reusable so I won't have to make one for each
type of entity...
Greetings and thanks in advance!
Nathan

This is not entirely correct.

You can create a method in your page or component class to return it:
public String getAction() {
if (row instanceof Entity1) {
Entity1 entity1 = (Entity1) row;
return entity1.getAction();
}
...
}
