Hi,
We have 2 common subflows for logging and exception handling in our project and we planned to do a small update on these 2.
Note :- exeception handling flow inturn uses the logging subflow.
We planned to make a configurable property for the validation as some users dont want to validate their messgae under some logging circumstances.
I tried to use the UDP(External Variable) concept to update the logger subflow. It worked fine after i promoted the value to the mainflow so that i could change it in the bar file.
But since the same subflow is used in the exceptionhandling subflow, when i promote the property 2 levels up, it puts 1 besides the propertyname.
for example my UDP is validate. I have the validate option for logger flow and validate1 for the exception handling flow.
Since its validate1, the flow is always saying , "User defined attribute must specify an initial value expression"in the exception subflow while getting deployed
Probably if i bring that logger subflow to the mainflow, it will be work fine, but i dont want to change the exisitng flow too much. |

Yes true, this will happen because UPD with same name is not allowed, just like when you use the same subflow in your main flow twice (1 is appended at the end for the duplicate).

NO, there should not be any error. This error is not because of validate1. Is this attribute mandatory and if so have you specified a value? When you have same UDP twice, a 1 suffix occurs for one of the value but this error does not occur while deploying.
Ideally what will happen is, if you have two UDP's os same subflow, say validate and validate1, the value of validate alone will be taken in the flows. So a better approach is to have two different UDP's to handle this scenario and handle the UDP value inside your subflows. |

your subflows. |
The solution is really easy:
If you want to set a unique value to the UDP on the bar file, and get propagated to all sublows, when you promote it from different places, drag&drop onto the firs promoted.
For example: if you have an UDP called System, and you promote it from the first subflow, it will appear with the name System. When you promote it from the second sublow into the same, drag it over the first promoted one.
It will solve your problem. |
