I got hit with a segfault again; started debugging again. This time, though,
I know the exact line causing the segfault!
In PropBinding.java, line 58:
public Object get()
{
try
{
return conduit.get(root); /** LINE 58 */
}
catch (Exception ex)
{
throw new TapestryException(ex.getMessage(), getLocation(), ex);
}
}
It's at that line that the segfault occurs. In checking the values of
everything in the debugger, everything seemed ok. In other words, the
conduit represented a string getter on my component. The only thing odd
(and it's not that odd, because I've done it before), is that the page and
the component have the same name: 'browse'.
Is there something else in the works here, such as Javaassist, that might be
the cause for the seg fault?

Seth
