1. Page instantiation. Page instance 1 {manipulating target data 1},
formComponent instance 1->target data instance 1.
2. Ajax request or similar onto page.
3. Page refresh (deserialized from diskstore). Page instance 2
{manipulating target data instance 2}, reused formComponent instance
1->target data instance 1.
So in stage 3 the page is manipulating target data instance 2 while
the reused form components still manipulate target data instance 1.
What this means? It means that for example if you Submit form, the
values will be updated onto target data 1. The mistake is that if your
Page instance 2 handles saving procedure, it will save the target data
{2} which does not receive the form submit.
This might work differently with detached models. I do not bother with
detached models on lightweight models.
