Override an existing properties panel component behaviour

[Ichigo85]

Is your feature request related to a problem? Please describe

I am working on upgrading my plugins to Camunda Modeler 5.0 and I am a bit stuck on a thing. I have to edit the behaviour of an existing field on properties panel (in my case, the MessageRef field) because I need to call one of my specific events on setValue. Is there a simple way to do it without re-writing the component and replacing it on the propertiesProvider#getGroups call?

Describe the solution you'd like

Support to override a field component, possibly without completely rewriting it, but only parts of it (getter, setter, validate, ...).

Describe alternatives you've considered

The only way I considered, as I said, is to re-write the existing behaviour of the field, overriding the setValue and adding my code.

I think this should rather be a feature request in the properties panel project: https://github.com/bpmn-io/bpmn-js-properties-panel/issues/new/choose

I transferred the issue accordingly, thanks for the request 👍

I think that would be an interesting slack time topic.

Idea(s):

• Fire event via eventBus on setter, getter, validate so others can hook into (cf. https://github.com/bpmn-io/properties-panel/blob/main/src/components/entries/TextField.js#L102).
• Make properties panel components extensible (replace setter, getter, validate)
• Make setter, getter and validate configurable via something like DescriptionProvider
