Sequence diag, conditions and attribute access?

[Roggan]

What is the correct way to draw conditions in EA?
ive seen some online samples of uml in general where they placed some box around the operatons inside a certain contidion.
eg a box for a contidion and antoer for a "else" statement.

also , how do i draw that one class access attribs on another class?

Use Fragments from the Interaction Toolbox. You can add several conditions.

For the attribute question I don't know of a solution. Only messages can be displayed. Maybe you can draw an anonymous message and add a note that some attribute is being accessed?

For me, multiple inline fragments can get annoying to work with.  Things get messy when you have to start moving messages around.  So, for simple if type logic, I prefer just setting a condition on the message.
