Hi!


My questions are:
1) How do I disable the sorting functionality of the grid.


Matheus answered that. :)


2) If I would like to suppport sorting and paging then I need some way to
first submit what's been checked.


I guess you can use some JavaScript in the paging links to do that.

   Hi, Gunnar!

   I think I know how to answer your first question. I assume your are using
Tapestry 5.2.4 as I am. :-) You need to create an explicit BeanModel,
customize its sorting funcionality and provide it to your Grid component.

*Page class*

@Inject
private BeanModelSource beanModelSource;

@Inject
private Messages messages;

public BeanModel getUnsortableBeanModel() {
   BeanModel model = beanModelSource.createDisplayModel(YourModel.class,
messages);
   for (String propName : model.getPropertyNames()) {
  PropertyModel propModel = model.get(propName);
  propModel.sortable(false);
   }
}

*Page template*



   You can add a checkbox column using BeanModel.add("propertyName", null).
It will be necessary to provide a render block for it in the template
(...).

   Atenciosamente,
