[Pharo-users] MetaLink after on a message with argument

Hi, I'm trying to install an #after metalink to a MessageNode that has an argument, however it fails because the bytecode is missing the argument (I think). Note that #before control worked fine, so I am not sure whether this is a bug, not yet supported, or am I doing something wrong. code (tested in P6.1): ~~~~~~~~~~~~~~~~~ Something compile: 'add: aNumber ^ 1 + aNumber'. after := MetaLink new metaObject: [ self logCr: 'after' ]; selector: #value; control: #after. " after uninstall. " ast := (Something>>#add:) ast. node := ast sendNodes first. node link: after. Something new add: 3. ~~~~~~~~~~~~~~~~~~~ error: [image: image.png] Thanks! Peter
