1) Standardised error codes

We discussed the idea of implementing standard error codes throughout 
all Seam modules.  These error codes would be unique, and allow Seam 
developers to reference a central database (such as Seam University) 
describing each error and possible workarounds.  The error codes 
themselves will be prefixed with a 2 or 3 letter code (that represents 
the module), followed by a number.  For example:

[SEC-1234] Invalid credentials supplied

The SEC prefix represents an exception in the Seam Security module.  
Other modules would have different codes, for example CAT = Seam Catch, 
VAL = Seam Validation, SVL = Seam Servlet, and so forth.  The number 
part of the error code will start at 0000 for each module.  The error 
message itself should support internationalisation, which will be a 
bonus to our non-english speaking users.  Each module will define its 
own internationalised message resources.  Ken is going to work on 
creating a new API in Solder which we can use to perform the logging of 
these errors.

2) Inter-module dependencies

The second topic we discussed was how we manage dependencies between 
modules.  It was agreed that wherever possible, dependencies should be 
optional.  An example of this is the dependency that seam-faces has on 
seam-catch.  In some cases it may be necessary for a module to have a 
hard dependency on another module, however if this becomes an issue in 
the future we may look at alternatives such as creating sub-modules that 
separate the integration from the rest of the module.

If anyone has any questions, feel free to ask.  We will be holding the 
DWG meeting in TeamSpeak once per month, on the first tuesday of the 
month - details can be found in the seam-dev calendar.

Thanks,
Shane
