Rails spinoffs - Aug 2007 - Error when updating to prototype 1.5.1.1 and scriptaculous 1.7.1 beta3 with page.replace

I need a little help please.  A newbie on rails, not much experience
with java.  My rails app worked fine and I upgraded to the latest
prototype and scriptaculous for a plugin only to break another part of
the app.

I''m using rjs to replace a partial on my page.  It used to work fine,
but now when it replaces it, it shows up on the web page as

try {

Element.update("close_goal", "\n");

} catch (e) { alert(''RJS error:\n\n'' + e.toString());
alert(''Element.update(\"close_goal\", \"\\n\")

;''); throw e }

in place of the html that should be there.

here''s the partial


<%unless @pending_close_goals.nil? %>
 <div class="pending_close_goal">
   The last scheduled task was completed.  Would you like to mark the
goal complete?<br>

  <%#for pending in @pending_close_goals
  %>
    <%=@pending_close_goals.summary %> &nbsp - &nbsp
    <%=link_to_remote "Mark Complete", :url=>{:controller=>
''schedule'',
                                :action=> ''mark_complete'',
                                :id=>@pending_close_goals.id},
                                :update=>''close_goal''
                                   %>
     &nbsp
        <%=link_to_remote "NO", :url=>{:controller=>
''schedule'',
                         :action=> ''not_mark_complete'',
                         :method=> :post},
                         :update=> ''close_goal'' %>
<br>
  <%#end
  %>
</div>
<%end%>

there''s some sortable lists with checkboxes that, when checked, will
change the count of the @pending_close_goals variable.  When one is
checked, this part of the page gets reloaded as well as the sortable
list.  That part works ok.  When you click on one of the links in the
partial, it will complete the action, but, when it replaces the
partial , it throws in that funky java text instead of rendering it.
(I rolled back all the changes I made and got to the last working
version, which worked fine, then updated those .js files and then it
broke!)

here''s the mark_complete.rjs

   page.replace_html ''close_goal'', :partial =>
''close_goal''

and the not_mark_compete.rjs looks like:

  page.replace_html ''close_goal'', :partial =>
''close_goal''

I''m including the standard js libraries using the
   <%= javascript_include_tag :defaults %>
statement.

If anyone could shed some light on what''s going wrong, that would be
greatly appreciated.  Again, it worked fine on the old versions of
those libraries (whatever came with rails 1.2.3)

Thank you in advance :)

This is what was posted when using prototype 1.5.0rc2: (which rendered
fine)

try {

Element.update("close_goal", "\n\n");

} catch (e) { alert(''RJS error:\n\n'' + e.toString());
alert(''Element.update(\"close_goal\", \"\\n\\n

\");''); throw e }

Notice that it was passing "\n\n" instead of just one \n.  Is that
part of the reason it is being shown as text, and not just rendered?

Any insight would be greatly appreciated.

Ok, I finally figured it out.

Two things were conflicting it seems (at least removing one fixed it!)

removing the :update=> ''close_goal''  fixed it.  It now
renders the
javascript generated via the .rjs file which is page.replace_html
''close_goal'', :partial => ''close_goal''

So, prototype 1.5.0rc2 let this go, but the 1.5.1.1 won''t ignore it
and gets all tripped up!  I guess its just making me a better coder!

I hope someone can benefit from this too!

Consider this discussion closed
Thanks
