What does "Signal:1" mean?

I am testing my Seaside development - Instantiations VAST 9.0 - and I am getting "Signal: 1" as an error. The problem is that the stack doesn't tell me where the error is, or at least not that I can understand. I attach a screen shot and the stack trace. Can anyone help me understand this please?

I guess you should take a closer look at this part of the Stack:

OrderedCollection(SequenceableCollection)>>#first self=OrderedCollection()

OrderedCollection>>#first self=OrderedCollection() TM470User>>#carCardForRoadNumber: self=a TM470User id='BM:33549'

[] in TM470CurrentTrain>>#constructCarsUsing: self=a TM470CurrentTrain aUser=a TM470User carArray=OrderedCollection('BM:33549' 'BAR:6724' 'CP:240000'

Seems like you try to use the first element in an empty Collection. Not related to Seaside, afaik.

Oh, shucks. Didn't open the stack up far enough! Back to the drawing board (or keyboard!).Thanks Joachim. Note to self: check the obvious first! (I wouldn't mind but I have been writing Smalltalk for 27 years so I should know this).David
