Hello guys,

I have multiple MWE2 workflow files inside the same project, and I am trying to introduce a central MWE2 workflow file (just like main class in java) which is invoking other workflow files.

After reading documentation, I found that using below convention, modules from other workflow files can be invoked: Quote:

@<modulename>

Central MWE2 workflow file content:

module mainModule

Workflow {
   component=@moduleOne {}
}

In this case moduleOne is defined in other MWE2 file

Unfortunately this doesn't seem to work and following exception is thrown :

0    [main] WARN  pes.access.impl.DeclaredTypeFactory  - --- xtext.common.types ---------------------------------------------------
1    [main] WARN  pes.access.impl.DeclaredTypeFactory  - ASM library is not available. Falling back to java.lang.reflect API.

I will be glad if someone can provide me a solution/hints to solve this issue.

For reference : I have attached the sample project which contains this scenario

you should put workflows into a source folder or use other means (e.g. use workflow as class folder) to have the second workflow on the classpath of the first one
