Summary0000362: PyGTK interface does not recognize solver_var as a variable type
DescriptionI set variable type to be solver_var in the attached model. This model works in the TclTk interface, but the PyGTK fails to recognize this as a legal type. It is a legal type. I loaded system.a4l manually first and then my model. The type solver_var is there. I then loaded my model again, and it still did not allow that type.
TagsNo tags attached.

I need to clarify this one. I have added a file models/test/solvervar.a4c. This model loads and solves fine in the PyGTK GUI. But I can't right-click and see the units dialog for the solver_var; I get a message saying that "No dimensioned types are available yet (have you loaded a model yet?)".

Then I get an error dialog which contains details as shown below.

Is this the error that you were seeing?

Traceback (most recent call last):
  File "pygtk/", line 509, units_activate(self=<modelview.ModelView instance at 0x9427fec>, *args=(<gtk.ImageMenuItem object (GtkImageMenuItem) at 0x943066c>,))
        T = self.get_selected_type()
        _un = UnitsDialog(self.browser,T)
  variables: {'self.browser': ('local', <gtkbrowser.Browser instance at 0xb7ca042c>), 'UnitsDialog': ('global', <class unitsdialog.UnitsDialog at 0x93be7ac>), '_un': (None, None), 'T': ('local', solver_var)}

Ah, OK. I looked at your vessel01.a4c file. I think that the issue is that in the PyGTK GUI, the 'Library' concept is rather different. Each time you load a new model file, the library is cleared out and only model files that are included by REQUIRE statements are ever included. So you always need to explicitly

REQUIRE "system.a4l";

somewhere in your model file.

There were also some problems with the use of the 'real' type. Changing to real_constant fixed this. Let me know what you think about the new uploaded file.

The problem with the properties dialog for wildcard variables appears to be solved. There is still a problem with the 'select units' dialog; have filed that as a new bug 0000489.
