<div dir="ltr"><div>Otto,</div><div><br></div><div>This was a head scratcher for a minute, but then I remembered that when you encounter an undefined Global in GLASS, the reference is replaces by a Set that references all of the methods(?) that contain a reference to the class ... the Set is magically used when the new class gets defined and the referencing methods are recompiled ... so you've either got a case where WARetryHttpRequest was undefined and if it has been defined in your image, then the magical methods didn't get run correctly ... If WARetryHttpRequest is present (most likely) recompiling that method should fix the problem ... and inspecting the Set from the debugger should give you references to the rest of the methods that reference WARetryHttpRequest ...<br></div><div><br></div><div>I've run out of time and have head to dinner right now ... let me know if you were able to repair things ... there is a undefined globals test somewhere that should give you some hints about the magic ... I'm out of time ... sorry ...</div><div><br></div><div>Dale<br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Mon, Oct 3, 2022 at 11:56 PM Otto Behrens via Glass <<a href="mailto:glass@lists.gemtalksystems.com">glass@lists.gemtalksystems.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr"><div>Hi,<br></div><div><br></div><div>I'm getting an MNU error SafelyPerformBlockRequiringAbort class does not understand #'do:' when I try to process a seaside request.</div><div><br></div><div>I'm building a GemStone 3.6.5 database starting with GemStone64Bit3.6.5-x86_64.Linux/bin/extent0.seaside.dbf and then loading all our Seaside / Magritte / Zinc stuff in there.
