I need some assistance

[Mario Jorge Nunes Filipe]

Hi

I'm creating an applet to show an outline in the form of a Jtree.

I created a class outline that supposedly parses a string and creates
the outline in memory, allowing me to write it out as string, or as a
tree.

The Outline class is in the attached file. I call this outline in the
following way :

out1 = new Outline("(No1,body1,(No2,Body2,(No3,Body3)),(No4,Body4))(No5,
Body5)(No6, Body6)");

DefaultMutableTreeNode root1 = out1.toTree();
DefaultMutableTreeNode root2 = out1.toTree();

When i run the above i only get

No6
No6

and i was expecting to get

No1
No5
No6

What am i doing wrong ?

I should add that i'm extremely newbie on this java thing and as such
the code is horrible, uggly, probablu not very much OO, etc

Thanks
