This is still an issue but not one I consider a high priority.  
DynamicViewEntity is mostly used for querying and not for updating,  
though in theory it should work fine for updating in certain  
circumstances, but I'm guessing that for real updates there would be  
more issues like this one because a DynamicViewEntity isn't real  
entity like a normal entity or a view-entity is because they aren't  
tied into certain other things.

For the display code I wouldn't recommend trying to modify any entity  
in-line, it can make the code confusing and you are restricted to the  
field names in the entity, so it often ends up becoming somewhat of a  
hack. It is better to create a more generic Map to put the data in,  
or just do getRelateds or whatever right inside the FTL template or  
form definition.

Of course another thing to keep in mind is that if you do prepare  
data in advance of the FTL/form/whatever then you need to make sure  
to do it on partial results to avoid running out of memory. If there  
is no chance of running out of memory it makes things easier, and you  
might even be able to simplify the query and such.
