Lotus Outline BUG

Found interesting bug in Lotus Notes, when outline is embedded in form and in some cases disappears from UI.
Simple experiment to reproduce the problem.
1) Create form
2) Create outline
3) Add button to form with code like @SetField("SomeField";"12345") or call ws.currentdocument.document.replaceitemvalue ("SomeField","1111")
4) Add outline to form
5) Save form.

Close Lotus Notes and delete cache.ndk from data directory.
Run Lotus Notes. Open created form in Lotus Notes client. Push the button - voila! Outline disappears!
Next time You open same form and push the button - it works fine (outline is in place).

The main problem is that, this only happens with non-cached outlines in cache.ndk. If You have 2 replicas on multiple servers, then opening each replica and pushing then button reproduces the problem again and again (possible recache for each replica?).

Workaround for this issue is, that You could use some form with all outlines included and loaded before main form - "cache" init form - it should load first, then the working form.

P.S. notes 7.0.3 has this bug I haven't found any workaround for it, but in 7.0.4 and 8+ works fine with cache form.
