Java NullPointer Exception on Windchill MPMLink

[RL_10799214]

I am using Windchill MPMLink Release 12.0 and Datecode with CPS 12.0.0.2

Any time we use the function'Assemble As New Branch' of XBOM Transform we obtain an error on screen: java.lang.nullpointerexception.

I would look at the MS logs and find where the exception is written. Posting that section of the MS log would help people see what this is related to.

Hi @RL_10799214 

You should provide full log error, several rows up and down around the error message from a server method log. 

Usually the information around is interesting, not just the error line.

Hi @RL_10799214 

Error while populating down stream part is path : java.lang.StringIndexOutOfBoundsException: String index out of range: -1

this error shows that some string value is empty or null, and that's why the error is thrown

Check OIR rules, there can be trouble with some conditions or some attribute is not shown in the wizard and it needs a value - check type and attribute layouts

Hi @RL_10799214 

Check the method server log, there is more information why there is null point exception as avillanueva mentioned

Anyway first think what came up in my mind is if you've correctly set the lifecycle, does the design object have a revise transition in the current state of design? it can case similar behavior.
