[rules-users] DSL: concatenating DSLs using "and" and "or"

Hi, We are currently using Drools to enable conditional routing for our application. We are using DSLs to make it more user friendly. Using Eclipse DSL editor, I noticed that there is an error (Duplicate Declaration of variable) if I use "and" to concatenate 2 DSL statements using the same variable name but this error does not appear if I use "or" For example, DSL Statement [when]there is an "{id}"=$node: Node(nodeId=="{id}") Using "and" (there is an "{id}") and (there is an "{id}") Using "or" (there is an "{id}") or (there is an "{id}") With the brackets, each DSL statement should be isolated right? But it is kinda tricky as if we need to use 2 or more DSL statements together using the same variable name. Also, is there any means to create unique variables for use in DSL, especially when joining for 2 or more DSL statements is required. Best regards Eric
