Comment 2 shche123 2008-05-12 19:21:08 UTC 
My settings do not auto add Constructor to the the Class diagram.
When I do add it and then gen the code, I get the runtime error...
Comment 3 Peter Lam 2008-05-22 00:46:59 UTC 
still exists in 6.5 as well as in 6.1. Not sure what's happening but I do get the error when generating code.
Comment 4 Viktor Lapitski 2008-07-18 03:05:29 UTC 
The project is somehow got into incorrect state:

1. there is a method that should be constructor, yet is doens't have 
isConstructor="true"
2. it has return parameter specified with empty type ( type="" )

<UML:Operation xmi.id="DCE.5F662313-A306-DE8D-5A84-F47F16E896A2" name="Account"
owner="DCE.0DB1A5E7-8868-EDAD-8AED-4DCA686961A0"><UML:Element.ownedElement>
<UML:Parameter xmi.id="DCE.74380533-7A08-99C3-CC16-7E20D9F16619" type="" direction="result"
owner="DCE.5F662313-A306-DE8D-5A84-F47F16E896A2">

This is, for example, how a constructor is supposed to look like:

<UML:Operation xmi.id="DCE.14EB7F16-7818-912F-A03E-B5B9D72BB2E0" name="cl3" isConstructor="true"
owner="DCE.5FEDABB3-A0D0-18FB-8016-8EFCE9D9A9E0"><UML:Element.presentation>
</UML:Element.presentation></UML:Operation>


A defensive code will be added to continue work in this situation as well.
