editor.{fields|tabs[].fields}[].control

← Back to the parameter index

Replaces the input with a file picker in a runMethod editor; on submit the panel uploads the file as a temporary file and sends its token in params[attribute]. Requires an explicit type String and no defaultValue; any other control value, or scratchFile in another editor, is a configuration error that blocks submission.

This is a compact property lookup. Use the contextual guide below for the complete feature model, configuration sequence, interactions, examples, and limitations.
