Re: Lookup & Search Redux

From the bulder POV all I need to do is ensure that a Resource exists
and open an input stream on it. In addition, if the Resource reps a
physical file (not jar) need to record 'problems'. Eclipse put those
red markers - I'm sure IntelliJ has an equivalent.

Eclipse is easy 'cuz both physical and jar files are represented by a
super interface (IStorage) so I can paramterize some classes to make
them generic enough for the non Eclipse case.

I guess there is always the fallback of realizing concrete instances
of those classes with an Object parameter - ugly but it would cover
anything. This is exacly what I'm dong to get unit tests (outside of
Eclipse) running.

BTW I have made it past the intial assertion checks (not nulls mostly)
and no past the "is this worth building at all?" check - I'm about to
try building the Framework library. yay.

With reference to the other thread - 4.0.3 - I just took a quick look
at Contrib.library and I see :

<meta key="org.apache.tapestry.component-class-packages"
value="org.apache.tapestry.contrib.components"/>

which is bad for me unfortunately - but there are only 4 Components in
that package.

Thing is that Framework and Contrib *used* to be very strict and
*everything* was explicitly declared. Things got loose in T4 timeframe
I guess.

component-class-package is one, of a couple, killer for T4 support. Is
4.0.3 dead for sure?

I'm hoping to get the new Spindle bulder to pass over Framework and
Contrib in the next day or so - could have a list of 'tweaks' by say
wed.
