Dear Orlenys López Pintado,

I installed Caterpillar on Linux Mint with versions of node, gulp and npm equal to:
^Cdanga@danga-mint ~/ProgramFiles/Caterpillar-master/caterpillar-core $ node -v
v8.5.0
danga@danga-mint ~/ProgramFiles/Caterpillar-master/caterpillar-core $ gulp -v

danga@danga-mint ~/ProgramFiles/Caterpillar-master/caterpillar-core $

When I start gulp in the folder caterpillar-core I get an error:
filterCreationErrorCallback is not a function
See output below - can you help me out with this?

Hi,

I try to run a process including a XOR gateway. However, it chooses by default the sequence flow that listed first in the BPMN file. When I set the bool to false, that is used by the gateway, according to the format in the papers, it results in a compilation error of smart contracts. I use version 1. What is going wrong? Is version 1 outdated? How do I solve it? I already inspected the code thoroughly, without positive result.

I am running caterpillar-core v2.0. Stuck with "name2Ids is not defined error".

Further analysis.

Filename: Caterpillar-master\v2.0\caterpillar-core\templates\bpmn2sol.ejs
line number: 308
Variable "name2Ids" is not defined in the file.

Whilst I look in the issue for more details - if there is anything missing from my end. Kindly let me know.

When gateways are added in a model, it returns a compilation error. I think the compiling process works after modification since smart contracts are printed, however, the error remains. How can this be solved? Help would be appreciated.

Execution - Panel in this project requires Nodev12.14 or V14.15, but Caterpillar - Core requires Nodev11.10.1. How to solve this problem?

If I want to use all the features of v1 correctly, what should my environment configuration be, for example: which version of nodejs to use

The project's README and scripts are not consistent on whether one should use legacy TestRPC or Ganache CLI.
I will add a PR that updates docs and scripts to only refer to the latter. I'm not sure if this is how it should be; but if it actually makes sense to use legacy TestRPC in a specific context (e.g. for Caterpillar version 1.0), I would expect that the docs explain this.

@orlenyslp @Benedikt1992 @TimKam
Hello! We completed all of the steps for the implementation of caterpillar that are stated in the documentation. First, we created a registry and we added a Process Model from the folder "DynamicBindingExample". We added the given binding policy from the folder "models" and deployed the Task Role Map with the two required IDs. We tried to create an instance from the process model - however, we are having troubles filling out the case creator role and the case creator address. For the case creator role, we selected "Customer", for the case creator address we tried every single address we found in the terminal and the database. We are getting the error "Task Role Contract Not Found" with every single one of them. Which address is the case creator address, where do we find it?

We already spent a lot of time with this and did every step until now successfully - however, help concerning our issue would be very appreaciated.
Thank you so much in advance!

When running the Docker image as specified in the README, I get the following error:

hello
I installed CATERPILLAR V2.1 and I am facing some issues when I am trying to create a new instance of a process.

I passed by those steps:
first, I created registry then I added the BPMN model after the compilation of smart contract
I did the binding policy static configuration and I deployed taskRolemap.
Finally, when I tried to create A new instance of a process I didn't find the case creator Role and case creator address.
Please could you help me to solve these issues and to understand more your solution
Thanks in advance
