</p>
<p>Hello,</p>
<p>Oh, that's not good. I'm still learning Squeak so I don't know
much about internals so I can't help much here, but I will try my
best.<br>
</p>
<p>I did some tests it seems like it's working in 5.3 but not in
6.0. Since I badly need some features of 6.0 (new functionality of
FFI), I'd like to help fix it ASAP. So, here are the steps how to
reproduce it:</p>
<p>On both 5.3 and 6.0 (20582) do the following:</p>
<ol>
<li>Load OMeta2Preload version 14</li>
<li>Load (attached to this email) changeset that makes
OMeta2Compiler methods compatible with current Compiler
interface + reverts change made to
CompiledMethod>>methodNode<br>
</li>
<li>Do it (or print i) the following in a workspace: <b>OMeta2
match: 555 with: #number </b>, or just any other example</li>
</ol>
<p>Result: on 5.3 should've succeeded (or signal "match failed")
with an output. On 6.0 will result in<i>
UndefinedObject>>findNextHandlerContextStarting.</i></p>
<p>Hope this somehow helps.<i><br>
</i></p>
PS. I also tried to change superclass of OM2Fail to Error instead of
Exception, to no avail<i>.</i>

<div style="font-family:Arial,Helvetica,sans-serif">Hello,<br>
<br>
I'd like to load OMeta2 package into Squeak 6.0 alpha
(version 20582. 64 <br>
bit) but I'm having issue with that.<br>
<br>
Attempting to load OMeta2.mcm results in <br>
UndefinedObject>>findNextHandlerContextStarting (As
result of <br>
#OMeta2Fail). It seems like exception handling mechanism
attempts to <br>
access sender but the sender is nil. I tried also to load
manually <br>
OMeta2-Preload-hmm.14.mcz (which works), then
OMeta2-Postload-hmm12.mcz <br>
but the same error happens.<br>
<br>
I recall, in Squeak5.3, this wasn't happening but further
errors were <br>
related with Compiler interface. I managed to fix that, by
adding <br>
Parser's method to #OMeta2Compiler. Unfortunalely there were
even more <br>
of these, which I could not fix.<br>
<br>
Is there any way to make it work? The package works fine in
Squeak 4.3 <br>
but I want to work in newer versions...<br>
<br>
PS. The image is fresh, I didn't even use Preference Wizard.
My OS is <br>
Windows 8.1 64 bit.<br>
