NewLisp Ide : problems with Ie 6.0

Maurizio · Post by **Maurizio** » Mon Sep 10, 2007 10:37 am

I've installed newLisp Ide in c:\programmi\newlisp
(that is, I have a directory c:\programmi\newlisp\ide containing
index.html, editor-frame.html, etc...

I made a desktop link to start the server as the following :
C:\Programmi\newlisp\newlisp.exe -httpd -d 8080 -w C:\Programmi\newlisp\ide

I made a c:\tmp directory.

If I start the server, I open a browser (IE 6.0) and then ask for:
http://127.0.0.1:8080

the main editor page appears correctly.
from this page I can navigate using the left directory tree and I can inspect the distribuition files.

However, As I click on a button (even NEW):
the editor page does not change,
the browser shows on the status line:
Apertura pagina http://127.0.0.1:8080/content-frame.cgi,
it keeps running the upper right icon , but it is not really waiting.

If now I click on another file name, it is correctly displayed in the edit window.
If I manually clear the edit window and I enter a simple expression
like (println "hello") and I click on the eval button, the above behaviour
repeats exactly as described.

This happens only using IE 6.0.
Using Mozilla Firefox all works perfectly
Any suggestion ?

Regards
Maurizio

I have seen this behaviour only on IE 7. IE-6 is fine on the WinXP machine and another WinXP Laptop I can use.

This problem has been reported before for IE-7 and on IE-6 when running with a http-conf.lsp file. A fix for this is high on my list, unfortunately I need a machine where I can reproduce it and do development at the same time ;-(

A debugging help may be to inspect the file
which are generated by newlisp in the tmp/ directory. This file contains the page sent to the browser after the CGI operation.

Unfortunately this file gets deleted immedately after the CGI operation took place by newLISP.

In nl-web.c in line 1206 there is a unlink(tempfile) statement which could be commented out to suppress deleting.

If you have a home network, you could try to access the machine from a client browser on a different machine, to check if that works. If it does work it tells us that the output id probably gnerated fine, but that there is something wrong with the I/O interaction of the newlisp-server and browser-client part on the same machine

I tried this on WinXP home on 2 machines, but could not repeat the error your are reporting. It works reliably (about a 100 page accesses) with IE-6 and Firefox with newLISP 9.2 and newlisp-ide 4.0.

This is my shortcut/properties to start newLISP in httpd mode:

Code: Select all

"C:\Program Files\newlisp\newlisp.exe" -http -d 8080 -w "C:\Program Files\newlisp\ide\

I don't know if it is a related problem, but I've just noticed the following :

I start the newlisp server, clicking on the desktop link,
then I open Ie 6.0 and I call the initial page :
http://127.0.0.1:8080
The first page appears, but IE shows a warning icon on the status bar.
Double clicking on that icon shows an error box with the following text:

riga: 38
carattere: 1
Errore: 'parent.frames.1.document.forms.0.dir' è nullo o non è un oggetto
codice: 0
url: http://127.0.0.1:8080/file-frame.cgi

The error seems to be JavaScript related. Row 38 is the end of a JavaScript section and the DOM ptr to the left frame returns 0. Is JavaScript enabled in that browser?

(sorry for the delay)
sure, Javascript is enabled.
