Forum OpenACS Q&A: Response to Why is ad_parameter deprecated?
don: i was planning on announcing this but was waiting because i want to rename one of the procs, parameter::set_value, to parameter::set, but i can't yet because there is a bug in the aolserver namespace code that does not let me do that.Whoa... hang on. I imagine that rather than a bug in AOLserver's namespace code, the bug is in the "redefinition" of the Tcl command set, at least within the scope of code executing in the parameter namespace.
i submitted a patch to the aolserver folks but they have not applied it yet.
When code runs inside the scope of a namespace commands (which are not themselves qualified with a namespace) are searched for in the current namespace, and, if nothing is found, in the global scope.
So if you define a namespace::set proc, then you need to explicity qualify all instances of set in your code (that runs in the same namespace) to use the global set, i.e. ::set.
