MessageNotUnderstood: MaMalformedRequestError>>repositoryController:

[Hilaire Fernandes]

Thanks for your advices, it is helpful.

In this place of the application I am not using read strategy.
In other place of the application where I am suing read strategy I don't
have the problem, so may be it is a problem underneath.

In the Magma client I only have the modification to
StrikeFont>>maAsStorageObject so TextMorph are persisted correctly. I
apply this change both to client and server : 

StrikeFont>>maAsStorageObject
^ DiskProxy
   global: #StrikeFont selector: #familyName:pointSize:emphasized:
   args: { self familyName.  self pointSize.  self emphasis }


Chris, I went until the MaTcp...>>submit: method, but I don't really
understand where to look. 

From the MaCommitPackage, the MagmaCollectionChanges looks like:

collectionOid: 	4112481
changes: 	a Dictionary(#added->an IdentityDictionary(66543->an
OrderedCollection(#(250776336) #(0) #(10625597) an IFILevelCollection()
#(1)) ) #removed->an IdentityDictionary() )
isNewCollection: false
collection: 	a MagmaCollection 


The problem happens when I add an object to a MagmaCollection

IFIDbSession commit: [pedagogicalMoments add: moment]

In this commit, TextMorph persitency occurs.
I repeat this code is working when Magma is in local mode.


In the client, MagmaRepositoryController basicNew protocol
returns, where only IFICompetencyCollection is new (the server has the
same protocol size):
