Forum OpenACS Q&A: Which is the best way to update acs-lang?

Hi all,

I installed openACS 4.6.3, but now I need to use the new acs-lang package. I would like to know which is the best strategy to follow knowing that the only package that I need to use, apart from the acs-core, is the edit-this-page package.

If I get the HEAD acs-lang version from cvs and just overwrite my old acs-lang folder and run the sql scripts I get this error:

unknown command "locale":  should be authpassword, authuser, close, content, contentlength, driver, flags, form, headers, host, isconnected, location, method, outputheaders, peeraddr, peerport, port, protocol, url, query, server, sock, start, status, urlc, urlv, or version
    while executing
"ns_conn $var"
    ("-get" arm line 20)
    invoked from within
"switch -- $flag {
    -connected_p {
      return [info exists ad_conn(request)]
    }

    -set {
      set ad_conn($var) [lindex $args 2]
    }

   ..."
    (procedure "ad_conn" line 12)
    invoked from within
"ad_conn locale"
    invoked from within
"set locale_user [ad_conn locale]"

And if I get all the openACS core from the HEAD, after fixing some bugs (problems with acs-lang sql creation script, with the calling to the 'lang::message::register' function inside the '/packages/acs-lang/tcl/lang-catalog-procs.tcl' file and with the absence of the 'locale' column in the user_preferences table), I get errors in the two versions of the edit-this-page package.

With the 1.1d version the file '/package/edit-this-page/www/etp' I get this error:

And with the 1.5d version the file '/package/edit-this-page/www/etp-setup-2' I get this error:

I know the HEAD version is not stable, but I have read some post of Lars saying that acs-lang would work well from the HEAD untill the next openACS 4.7 version.
Should I wait till the 4.7 (when is the release scheduled?), or can you help me with these errors?

Thanx in advance,
