Can't save simbiology model - java error

I am experiencing a java error that is preventing me from saving my simbiology experiment. I am running Mac OS yosemite and Matlab 2014b. I have been running 2014b on Yosemite for over a week and this is the first problem that I have encountered. There is also a java error in the command line of the main matlab window that reads:

Exception in thread "AWT-EventQueue-0" java.lang.NullPointerException at com.mathworks.toolbox.simbio.util.tablecell.BooleanCellRenderer.getTableCellRendererComponent(BooleanCellRenderer.java:44) at javax.swing.JTable$AccessibleJTable.getAccessibleChild(JTable.java:7039) at com.mathworks.mwswing.MJTable$ExtAccessibleJTable.getAccessibleChild(MJTable.java:935) at javax.swing.JTable$AccessibleJTable.getAccessibleAt(JTable.java:7426) ...along with ~100 more lines

The error code that I receive when I try to save the project is in the screenshot.

Please help! I'm worried the whole thing will crash and I'll need to rework the entire model.

Alex - you didn't attach a screenshot. Make sure that you press the Attach File button.

Sorry Geoff, the screenshot is now up.

I received a reply this morning from Vijay, a simbiology developer, with instructions on how to output and save my model from the matlab command line.

His instructions worked for me:

"As a workaround, I would suggest exporting the model to the MATLAB workspace by going to the Model Tab -> Export -> Export Model to Workspace, this typically exports the model with a default name of m1.

After your model is exported to the MATLAB workspace, you can save it by calling: sbiosaveproject('<projectname>', '<model_name>') .This should save the model in an sbproj file in your MATLAB current folder.

This will save your model, but not any tasks you might have."
