Activity Diagram

[ayman]

hello,
using EA v10 i need to add a constraint for an action as follows:
1- to be pre condition and seen visually
2- the constraint about the required data needed to execute the action e.g to execute action1 as a precondition these objects should exist obj1,obj2 ,etc...

Actions don't have pre-conditions. They are reached via a Control Flow that has a Guard. I don't understand your 2nd point but think you mean Object Flow. Create an ActionPin an let the objects flow into that as desired.

hello,
according to help guide:
"Actions can be further defined with pre-condition and post-condition notes, which constrain an Action's entry and exit."

For point 2: what i need to do is define the mandatory input and output data objects needed for action as i explained

[qwerty]

What they mean is to attach a Context Menu/Common/Constraint which allows to define pre-/post-condition.

don't get the point?

[qwerty]

In the diagram open the context menu (right click).Then choose Common/Constraint. This creates a special note where you can select pre-post condition and which lets you enter some text. Now you can link the to anything - like an Action.
