I understood that with this version some problems with this routine would be fixed. However,

I just installed 2.1.3.007 and I'm still getting with this code:

<cfoutput>

<cfif true>is true<br></cfif>

<cfif false>is not true<br></cfif>

    #Now()#
    <cfset getPageContext().forward("/graphics/logo.png")>

</cfoutput>

This output:
is true
is not true
#Now()#

Tom,

I still have issues with the getPageContext().forward() routine on 3.1.2.007.  When trying to forward to another CFML page I get a stackoverflowerror.  Error message below.

Please create issues in JIRA with these reproducible test cases!

Thanx,
Sean

Thanx Tom!

That'll make sure it gets addressed.

BTW, this is also why the dev branch is bleeding edge and not suitable
for production - so bugs like this can be found early and fixed.

Assuming we do find a bug, and don't see anything in the group nor any
jira ticket on it, does Railo prefer that we bring it up on the group
first, or just submit a ticket?

Both.

Hi Andrew

can you please post the complete stacktrace, this part shows me only a loop inside jetty
from org.eclipse.jetty.server.Dispatcher$ForwardAttributes.removeAttribute to org.eclipse.jetty.server.Dispatcher$ForwardAttributes.setAttribute and back,
looks more like a issue in jetty

we have solved the Problem for railo 3.1.2.008, it was only a issue with Jetty.
we have tested it with Jetty,Tomcat and Resin.

But there is a problem with forwarding to a image like you do in the example below, this does not work like expected, the respone has the wrong content type and the browser display the image as text output.
because this happens outside railo, we cannot  "fix" this.

Michael,

I saw your response after this one.  So I will not send a stack trace but I wanted to relay some more information and ask one question.  I have multiple installs of Jetty & Railo.  Some on client's equipment and some on my own servers.  On one of my dev installs the .007 release worked when I ran my forward test.  I am really perplexed now.  So I reran the test on the same hardware as yesterday to reproduce the stack trace.  I got a different error message this time around. Do I need to reboot the box to get an accurate test?  Seems like the results should be the same on each test.

It depends on the nature of the bug.

If the bug causes uninitialized memory to be referenced, the behavior could be different every time.

(this sort of thing is no longer obvious to programmers who don't have a low-level comp sci background - one of the big problems with the increasing level of abstraction in both programming languages and how they're taught - sorry, a bugbear of mine as an old-school comp sci guy... a *very* old-school, grey-haired guy :)

I'm glad I'm not the only grey-haired guy around, what little's left is
grey anyway. Guess you could call me punch card old. Problems not
withstanding, I just love increased level of abstraction (and not having
to worry about dropping that stack of cards).

Thank you for working on this issue. Once I again I am very impressed
with the level of support from the Railo Team. I recommend Railo to
anyone that will listen.

Ah, now that was real computing! I had several projects early on in my
career where you wrote code out on special graph-like paper and sent
it down to the data entry folks to type in... and we did backups on
punched tape (not very reliable). And multi-user machines had just 4MB
RAM :)

True, the abstraction has been a boon - and OO and Functional
Programming styles have moved us a long way forward from procedural
style in terms of expressiveness and maintainability.

When I was at Macromedia, I was one of the oldest guys on the team.
That changed once Adobe bought Macromedia, of course...

I think I'm the oldest guy at Railo... I like being the old curmudgeon! :)

What's funny is my Grandpa was telling me stories about his old job back in the day. What was it? He "took these cards and had to punch holes in them then stick them in the computer for it to process them" to which I responded "you were a programmer?" haha

I guess I was destined to join the dev ranks. :-D

my high school had card that you marked with pencil - one card per line.
Not so bad when you program is only 20 lines long.

At the same time my Dad built his own computer from an Electronics Australia magazine.
It had a key board and monitor (read black and white tv).

I am guessing my hair would be grey if it hadn't all fallen out first :-(
