Mermaid Classdiagrams are not working

[vikram-rawat]

The example mentioned on the mermaid git page is not working properly in Diagrammer

classDiagram
Class01 <|-- AveryLongClass : Cool
Class03 -- Class04
Class05 o-- Class06
Class07 .. Class08
Class09 --> C2 : Where am i?
Class09 -- C3
Class09 --|> Class07
Class07 : equals()
Class07 : Object[] elementData
Class01 : size()
Class01 : int chimp
Class01 : int gorilla
Class08 <--> C2: Cool label

Mermaid has just updated some code. Now the class diagram are working perfectly on mermaid editor but they are still not working on Diagrammer.

Please update.

@vikram-rawat I'll take a look into this and see if I can update mermaid within this package. Thanks!

Hi Rich,

looks like I'm experiencing the same issue as mentioned above. Can it be that there is some update at mermaid that is not yet incorporated in Diagrammer?
