I agree, +1 for a form-based approach. Being able to make changes there and observe the output BPEL would help users learn the format and structure. Thanks, Colin Roy-Ehri Software Engineer *WSO2, Inc. : wso2.com http://wso2.com/* *Mobile* : 812-219-6517 On Sat, Apr 25, 2015 at 6:07

Dear Pulasthi, having a way to define simple BPEL processes in a form-based manner would be great! Do you have some details on this? Best regards, Frank 2015-04-20 8:42 GMT+02:00 Pulasthi Mahawithana pulast...@wso2.com: Hi Frank, We thought of having a simple form based approach at user

Hi Frank, We thought of having a simple form based approach at user end. We will use some BPELs as templates and get the inputs from a form to customize it. On Sat, Apr 11, 2015 at 8:02 PM, Frank Leymann fr...@wso2.com wrote: Hi Pulasthi, when you have users without BPEL knowledge in mind,

Hi Pulasthi, when you have users without BPEL knowledge in mind, you assume that these users have programming skills, correct? I.e. that they provide the workflow process in JavaScript, for example, correct? Or do you work on a new very easy-to-use workflow language? Best regards, Frank

Hi Manfred, The workflow support is not coupled to WSO2 BPS (except the tool for creation and deployment of simple workflows which I mentioned in the previous mail), it can be used with any external BPEL engine. So, In the case of an external BPEL engine we cannot share the data at DB level. That

Hi Pulasthi, thank you for info about BPMN implementation. Is the workflow executor database a datastore for workflow-data at product-level? The called workflow engine stores the workflow-data for execution in BPS, right? This leads to redundant workflow-data. Why should/can I not install

Hi Manfred, The executor can be used with both. BPEL only support is for the tool we plan to provide for creation and deployment of simple workflows. We will consider extending it to support BPMN also when the next WSO2 BPS version is released with BPMN support. On Mon, Apr 6, 2015 at 12:11 AM,

Hi Frank, I sent a separate mail[1] with the architecture. Our main objective was to provide the workflow support for the events in IS and [1] was designed to address that. Furthermore we plan to provide a way to easily configure a workflow process and deploy it at BPS (for the users without BPEL

Hi Johann and all, As per the offline chat with Pulasthi, the executor serialize the workflow info and save in the database before calling the bpel service. (see the diagram below) ​So in our case if we are to use this component, we will have to do a network call with all the information for
