malformed URI sequence problem

Hey,

Why would this "id=137&tags=com%E9dia%2C%20lala" spawn a
"malformed
URI sequence" error on both Firefox and Safari when using
InPlaceEditor?

All I''m doing is:

//<![CDATA[
        new Ajax.InPlaceEditor(''tags'',
''add_tags/'', {rows:1,
callback:function(form, value) { return ''id='' +
escape(''137'') +
''&tags='' + escape(value) }})
//]]>

When I remove the escape from the tags value the problem goes away (at
least for the utf8 encoded strings, which seems to be the source of
the problem), but if any special URI char is entered in tags (such as
&, = or ?) it spoils the whole query...

Firefox fails at this line of prototype:

 237 var value = pair[1] ? decodeURIComponent(pair[1]) : undefined;

Thanks,

fabio.

Re: malformed URI sequence problem

What version of Prototype are you using? The 1.5.1_x versions convert 
the parameters property into a hash using String#toQueryParams and then 
back to a string using Hash.toQueryString so you might want to test your 
callback string with these functions.. i.e.

callback:function(form, value) {
  var paramString = ''id='' + escape(''137'') +
''&tags='' + escape(value);
  var paramHash = paramString.toQueryParams();
  if(paramString != Hash.toQueryString(paramHash)){
    alert(''not equal!'');
  }
  console.debug(paramString); //firebug
  console.debug(Hash.toQueryString(paramHash));
  return paramString;
}

If you get the "not equal!" alert or the same "malformed URI
sequence"
error, let us know and report the problem on the Prototype:Core google 
group.

Re: malformed URI sequence problem

I''m using 1.5.1_rc1, since it''s the last one with a
Scriptaculous
release as well.

I''ve tried your snipped only it never gets passed
> var paramHash = paramString.toQueryParams();
since it''s the toQueryParams() call (with following decodeURIComponent
call) that seems to be the problem.

I''ve tried a couple of things, yelled "This is Sparta!!!!" a
couple of
times to my macbook and finally realized it could be that Prototype is
using decodeURIComponent instead of unescape and the two functions
might handle those special latin chars differently in a pure utf8 env.
I''ve started using encodeURIComponent in the callback and things
started working.

I''m guessing this might come in handy to a lot of people, since
escape() is what''s widely used in callback function examples for both
Prototype and Scriptaculous.

Cheers,

fabio.

Re: malformed URI sequence problem

Well, it''s a GET request in the end so it''s supposed to pull
the trick.

Come to think of it, I''ve had to use it instead of escape() in the
past while passing vars to Flash Movies (which use utf8 by default).

If Prototype''s supposed to work with a callback function that
escape()''s the query string it returns, then be warned that up to
1.5.1_rc1 it doesn''t work with utf8 encoded pages/forms.

Regards,

Fabio.
