JS Transformation stopped working after upgrade to 2.5.6 snapshot #131

Ran snapshot #111 (v2.5.5) and JS transformation within a sitemap item label. Worked always fine. After upgrading to 2.5.6, snapshot #131, this stopped working. A sitemap failure is not shown. But if i choose the group with the irem label containing the JS transformation, this Group doesn’t open. Openhab log file shows some errors with “JS Transformation helper” Has anybody an idea what i could do? Best regards, Willi
