LrDevelopController.revealAdjustedControls opens Lens Corrections panel instead of the new Transform panel when controls in the Transform panel are adjusted by a plugin. Please fix ASAP! It kills the usability of plugins that manipulate develop adjustments!
As a workaround while waiting for Adobe to fix the bug, the plugin could call LrDevelopController.revealPanel ("transformPanel") whenever it adjusts a Transform setting. That would ensure the Transform panel is open (though the Lens Correction panel will also open).
