Hi,

I've started using the latest interim release, and now I'm having
problems creating new launch configurations for evl files. The creation
itself works, but I cannot add any model file(s) without getting the
following error:

java.lang.NullPointerException
at
org.eclipse.epsilon.common.dt.launching.dialogs.ModelTypeSel ectionDialog.findModelTypes(ModelTypeSelectionDialog.java:17 9)
at
org.eclipse.epsilon.common.dt.launching.dialogs.ModelTypeSel ectionDialog.createDialogArea(ModelTypeSelectionDialog.java: 88)
at
org.eclipse.jface.dialogs.TitleAreaDialog.createContents(Tit leAreaDialog.java:155)
at org.eclipse.jface.window.Window.create(Window.java:431)
at org.eclipse.jface.dialogs.Dialog.create(Dialog.java:1089)
at org.eclipse.jface.window.Window.open(Window.java:790)
at
org.eclipse.epsilon.common.dt.launching.tabs.ModelsConfigura tionTab$AddModelListener.handleEvent(ModelsConfigurationTab. java:171)

It is possible to (duplicate and) edit an existing one, but this is only
a solution if you have one already.

It worked, thanks!

My students are working on their first assignment, where they must use
Emfatic and HUTN for creating a model and sample data, and eol/evl for
constraints. They're very grateful for the quick response :-)

A quick comment on creating launch configurations for evl files: I would
guess the usual case is validating a single model. Hence, a slightly
different design, where the source and model are chosen on the main tab,
and the other tab used for adding additional models, would make sense.
What do you think?

Hi Hallvard,

Is this just a UI issue (given that EVL already supports access to
multiple models)?

Yes, it's a simplification for the case where there is only one model,
based on the observation that my students find the current design a bit
confusing.

The existing Models tab can be kept as is, while the Source tab is
augmented (and renamed) with fields for setting/editing one (the first)
model, so the typical case becomes a bit simpler.
