Auto-trim leading whitespaces when pasting into property fields

[christian-konrad]

Is your feature request related to a problem? Please describe.

When you copy things like URLs and paste them into the properties panel, it can happen that you accidently copy leading white spaces. They will be copied into the property field, and you might not spot that easily. This can lead to problems such as regex validation failing (in the URL example), and the user does not understand why.

Auto-trim leading whitespaces when pasting into property fields.

Describe alternatives you've considered

We need to confirm that there is no valid use case of pasting leading white spaces that we will break with such a feature.

What we need to consider is that sometimes you actually want to paste the leading space in case you append content to existing value. Still, I think the requested feature would absolutely make sense for empty fields.

This may be a quick fix for the bigger issue reported once in a while by our users: camunda/camunda-modeler#2385.

Often times (in technical configuration) whitespace is bad. More general trimming is what we considered in the past, but did not follow up on.

Any chances we can pick this up? We had another support case where a customer created an invalid Connector config by having a whitespace character in their properties which lead to a long running incident process.

We can take this to the next iteration planning given that it's such a pain for the users. Can you please link the support case in the top comment? We could then label the issue as channel:support.

@barmac I dont have the permissions to do so. Here is the support ticket: https://jira.camunda.com/browse/SUPPORT-25217?focusedCommentId=390503&page=com.atlassian.jira.plugin.system.issuetabpanels%3Acomment-tabpanel#comment-390503
