#52 Crash in CompositionView.cs on setting Get Values call

[John Barnes]

This problem seen while building a composition using .omi and .fcs files (attached) generated by Component Builder for the C# implementation of the Pond tutorial example.

To reproduce the problem:

• start Pipistrelle and add the component using the attach .omi file
• right-click on the CB_Pond component and click on the command Set as "Get Values call" ...
• select OutFlow in the Select dialog and confirm

Pipistrelle crashes at line 241 of CompositionView.cs because output.Component is null. See attached screenshot Capture.PNG for details.

As a temporary workaround so that I could make progress I changed line 241 to read:

            var componentItem = _composition.GetItem(component);

Opinions on whether that is a legitimate change would be welcome.

I can't reproduce this - when i try to select OutFlow there is nothing to select... also the CompositionView.cs lines 240-242 read:
foreach (var item in _composition.ExchangeItems)
if (item.Interface == IdentifiableItemType.IBaseOutput
&& ((IBaseOutput)item.ItemInstance).Component == null)

which seems to have little relationship to the change? The line you have used is available on line 255 of the same file?

Sorry about the typo - the line I changed was 1241 (as confirmed in capture.PNG).

I have set this up again using the files attached to to this Ticket in a fresh folder and can select OutFlow OK - see Capture2.PNG attached.

The problem described in this Ticket disappears when the fix described in Ticket #53 is applied, so I suggest we close this Ticket on that basis.

Ok – sounds good to me!
