Activity Diagram - How to merge different else conditions

0 votes
asked Apr 5, 2022 in Question / help by Bini

Hi

New user to PlantUML. I have a few IF/ELSE scattered about where the main chunk I have defaulted the 'happy path' with no action but it merges to a final action below. The else part of all of these I have had to duplicate an action + stop. I am sure there must be a way to merge them as well but not able to figure it out. 

Below is the text, the entries in red are the ones I feel I shouldn't have to duplicate and also I am not sure I want to 'stop' either as I have not done the analysis but feel if they can be merged to another action will continue to another path with further actions.

thanks

Bini

Hello B.,

See similar request here, and on the forum:

But, without `swimlane`, you can use experimental `goto`, (with some overlapping...) as:

If that can help,
Regards.

Thank you for the prompt reply. So "goto" is one option, the lines will start to look messy i guess but makes sense.

If I were to draw it manually I would somehow merge them to one.

Much appreciated

Goto does not work whether direct in online server or via the confluence macro for plantuml.

I have revised below to be complete but am struggling on 2 points.

1) I want to join "Store XVA for reporting" to connect to "Send Price To Client"

2) Under "Pricing" group I want to avoid duplicating "Apply MU to TraderPrice" if I can merge into 1

3) Under "Pricing" group I have an extra condition on the right that could never be met as 1st 3 conditions will not allow, so how do I remove?

Any help on this will be appreciated.

thanks
