Re: T5: timeout exception when using Grid - Solved, but query
My grid data required a model. In copying this in from an example I had:
@SuppressWarnings("unchecked")
@Property
@Retain
private BeanModel _myModel;
The key here is @Retain. This works fine until there is a timeout
(default 10 mins) and the page is returned to the pool whereupon it
becomes null and thus causes Grid to fall over when it attempts to
render. Changing Retain to Persist cured the problem. That's rather a
nasty gotcha.
QUESTION
--------
Currently I am creating my model in initialisePage(). If I were to
contnue to use @Retain rather than @Persist, where should I be
initialising my model?
thanks,

Many thanks Ville.
Quite obvious when one sees how to do it!

Re: T5: timeout exception when using Grid - Solved, but query
Posted by Ville Virtanen <vi...@cerion.fi>.
This is what we use, and it works well:
@Retain
private BeanModel model;
{
model = beanModelSource.createEditModel(Organization.class,
messages);
model.add("organizationType");
model.add("parentOrganization");
}
public BeanModel getModel() { return model; }
