How to copy a Business Process

prioux · March 27, 2019, 3:14pm

Hi,

I have a Business Process defined in the modeler. How I can copy this Business Process to another model using the REST call or Java methods directly?

I have look at /models/{modelId}/editor/json GET and POST method but not quite sure if this is possible using those methods.

The use case is:

I have a Business Process A (template)
I am creating BPM B
Want to perform a copy A into B

Hi prioux.

flowable-ui-modeler-rest module (and flowable-modeler app) has rest point to clone model.

github.com

flowable/flowable-engine/blob/5c0162b790120f1773bb0d15589867d7ee9279ea/modules/flowable-ui-modeler/flowable-ui-modeler-rest/src/main/java/org/flowable/ui/modeler/rest/app/ModelsResource.java#L143


}


protected void checkForDuplicateKey(ModelRepresentation modelRepresentation) {
    ModelKeyRepresentation modelKeyInfo = modelService.validateModelKey(null, modelRepresentation.getModelType(), modelRepresentation.getKey());
    if (modelKeyInfo.isKeyAlreadyExists()) {
        throw new ConflictingRequestException("Provided model key already exists: " + modelRepresentation.getKey());
    }
}


@RequestMapping(value = "/rest/models/{modelId}/clone", method = RequestMethod.POST, produces = "application/json")
public ModelRepresentation duplicateModel(@PathVariable String modelId, @RequestBody ModelRepresentation modelRepresentation) {


    String json = null;
    Model model = null;
    if (modelId != null) {
        model = modelService.getModel(modelId);
        json = model.getModelEditorJson();
    }


    if (model == null) {
        throw new InternalServerErrorException("Error duplicating model : Unknown original model");

That’s the one of the ways how to copy model.

Regards
Martin
