Hi there,
I’m trying to extend modeler so a new task type could be added whether using context pad or by adding a task then using popup-menu or whatever other approach possible.
I’ve read all the documents and examples which BPMN-IO amazing developers have provided.
But after spending a couple or more weeks on trying all these examples, I couldn’t find my way towards my goal.
IS there anyone who could give me a hint what am I missing? or it could be a lot more helpful if a simple (step by step like for dummies ) walk-through for this was possible?
Regards
ps: I wasn’t sure if it’s possible to extend moddle by adding new task type till I read some topics and figured others have done such
ps: sorry for the long description
Hi @Niklas_Kiefer,
In the way of completing my thesis work, I have to add a new task type for analysts in order to give them the possibility of querying and inserting into some sort of a knowledge base (a knowledge graph).
What I have tried so far is I was able to create a new icon according to bpmn-font guidelines and added that to a context pad.
but when I click on the new item in the context pad it shows errors.
then I figured there should be something I’ve been missing so tried examples related to element factory but that come to a dead-end.
now I think I should have some sort of create function and for example in the context pad code have something like this:
first is this right? second, how do I do that?
I thought I could do that in a custom element factory but now I’m not sure.
By the way thank you for your quick response; that’s really promising and I really appreciate it.
ps: sorry if I didn’t use the CodeSandBox link that you sent. actually I didn’t know how to work with it (please don’t be disappointed of me )
ps: again sorry for this long message

How does your custom task look like?
Do you have any moddle descriptors defined for it?
but when I click on the new item in the context pad it shows errors.
What kind of errors?
Again, these questions would be easier to solve for you and for us if you could provide the stuff inside a CodeSandbox. You can also post the code here, but a Sandbox would make our lives much easier. So maybe worth it to try it out
if you mean the extension I must define in json format yes I have.
ok I give it a try.
this is what I ended up with: CodeSandBox
@Niklas_Kiefer I made it like the way it is shown in the Sandbox and when I click on the custom icon a triangle appends to my diagram. and now I have some more questions.
first of all how can I change that so it could be like the icon for my task that I designed formerly?
secondly I couldn’t figure out how to do it with popup-menu instead of context pad. Is there a way to do that?
I wanna append an appropriate icon instead of a triangle. I’ve read BpmnRenderer.js and apparently I have a short knowledge of svg so I’m currently spending time on that.
thank you @Niklas_Kiefer. you really helped me out of my situation.
