[Geotools-devel] Auto-commit transaction in *ShapeFileDatastore in GT 2.2.x

[Vitali D. <vi...@ar...>]

Hello!

If an auto-commit transaction is used in ShapeFileDatastore then during any
features modification  FeatureListener[s] do not get any notifications. Only
if the transaction is non-auto-commit then DiffFeatureWriter and
TransactionStateDiff contains the code to notify listeners.

It causes UDIG, for example, not to re-render the layer where features were
modified/added/removed (in case of shapefile).

Am I right with this suspicion?  Seems the notification mechanism is spread
among classes.. Isn't implementation of FeatureStore is the right place to
have notification mechanism and way to turn on/off, batch notifications,
etc. ? No matter what is a nature of datastore, the FeatureStore
implementation may collect necessary information from datastore specific
implementation classes but send these notifications in a centralized way. 

I did not look into JIRA yet, so may be this is a known issue.
