Re: Class cast exception

[Christoph Reck <Ch...@dlr.de>]

Please send questions explicetely dealing to the Velocity 
features to that list.

The simple answer is that Vel does not support accessing
the fields of an object (instance). When trying to get
data via the Bean-Like interface you need to keep the
initial capital to the Method. So your second snippet 
should have looke like:
#foreach ($cd in $CDs)
<TR>
    <TD>$cd.Artist</TD>
    <TD>$cd.Title</TD>
<TD>$myLink</TD>
</TR>
#end

I have proposed to the Vel team to do automatic uppercasing
of the first letter when searching for the appropiate get 
method - to be more bean-conform, but had no luck. 

The reason for a class cast exception needs to be further
traced.
