Re: 5.4-rc-1 - problem when *add* a column to a *grid*, but it is working OK in 5.4-beta-26

First of all, I have made a mistake in the subject - it was supposed to 
be 5.4-rc-1

The added property is not a member of this class properties, so I see no 
real reason why including the other properties should matter. But, I do 
get why you are suggesting that.


On the other hand, I would prefer not to use the "include" since it 
polutes the (H)THML with with internal (read: database) details. On the 
other hand, "add" is just a view layer thing, since you add an 
interaction element to the (H)TML.


But, this debate is fruitless, because it does not matter.
I tried using "include", the problem remains.

I guess the real reason for this happening is some incompatibility, 
between some of the libraries, but I have spent many hours to find the 
problem and tried many combinations  without luck. So any ideas towards 
finding a solution would be great.

I don't know what you mean by having tried many library combinations. But
Tapestry related libs should all be the same version and without duplicates
in your runtime.

The error you are getting happens because the BeanModel for your grid
already contains a property called "delete".

So if you actually tried using  and got the error, something is really off...

You can try to attach a debugger to either Grid, BeanModelUtils or
BeanModelImpl to see what your generated model contains... or create / bind
a bean model explicitly and debug using that.

If I replace
  add="delete"
with
  add="deleteHVUHDVIUDHVS"

I will get a message that the Model already contains "deleteHVUHDVIUDHVS"


So if you actually tried using  and got the error, something is really off...

As I said, I did try that and still get the error.

Will try.

So in the tml I know have a random property name:



Calling:
 model = bms.createDisplayModel(Degree.class, messages);
 System.out.println(model.getPropertyNames());
Printout:
 [degreeId, code, title, titleEn, terms, note]

As you see there is no property "deleteuh9uhco9qh98ehv" in the model.

But, the error occurs again:
*Bean editor model for mk.ukim.finki.isis.dossier.entities.Degree 
already contains a property model for property 'deleteuh9uhco9qh98ehv'.*
