For convenience, I have called the parts 'A' and 'B' to describe my issue.
I have inserted several instances of part 'B' (which has 2 configurations) into part 'A'. When 'A' is opened, I am unable to select a configuration in part 'B', UNLESS part 'B' is opened as well: right clicking on part 'B' and selecting Edit in context (which effectively opens up that part file in a second window).
The Help file says: To change the configuration of the inserted part:
1- Right-click the part and select List External Refs. 2- Select Use named configuration, select a configuration from the list, and click OK.This is true if the inserted part is also opened. If not, the options to change configurations are grayed out.
This make part 'A" very unstable, as all the instances of part 'B' revert back to their default configuration when opening 'A' on its own. When opening 'B' as a second window and switching back to part 'A', SWX rebuilds 'A' and changes 'B' to the originally selected configuration for each instance.
Is there a setting in Tools / Options that controls this behaviour, or does this mean that 'B' needs to be opened systematically when opening ?A'? Thanks.
