Hi I need help in making a tree as member of a variable: heres a
summary of my code

oo::class c {
method connect {
my variable my_tree

set html_source [ http::data $token ]
struct::tree my_tree
htmlparse::2tree $html_source tree
}
}

I get this error message

invalid command name "my_tree"

"$tree set root type root"
(procedure "htmlparse::2tree" line 17)
invoked from within
"htmlparse::2tree $html_source my_tree"


any ideas?

i was able to fix this. I just replaced
> htmlparse::2tree $html_source tree

to

> htmlparse::2tree $html_source "[self namespace]::tree"

We apparently an issue with scoping, the tree is not where you thought
it is. One possible fix:

set thetree [struct::tree my_tree]
htmlparse::2tree $html_source $thetree

The result of struct::tree is the fully qualified name of the object,
sdaved into a variable, it can then be used regardless of location
relative to your current scope.
