What it does

Reports a Button (ia.input.button) that has enabled actions on both events.dom.onClick and events.component.onActionPerformed.

Why is this bad?

A mouse click on a button fires both events, so the work runs twice (two writes, two popups, two navigations), in an order that is not guaranteed. onActionPerformed also fires for keyboard activation, so it is the one to keep.

Example

"events": {
  "dom": {"onClick": {"type": "script", "scope": "G", "config": {"script": "\tsave()"}}},
  "component": {"onActionPerformed": {"type": "script", "scope": "G", "config": {"script": "\tsave()"}}}
}

Use instead:

"events": {
  "component": {"onActionPerformed": {"type": "script", "scope": "G", "config": {"script": "\tsave()"}}}
}
