…ue} }' when the PSAlignAssignmentStatement setting CheckHashtable was turned on. The reason for it was because the previous implementation expected the key in a hashtable to not contain more than 1 token expression.

is there a test for this? |

@JamesWTruher Although the issue occured only in a very special scenario and enviroment, I added a test for it. But the underlying problem in the code was just that a function was returning null to something that was |

thanks - even though it's an unlikely error, I would rather have an additional test, just from a process perspective. |
