Hi!
I have been away from WEB development and Tapestry for a while now. Yesterday I decided to try use Tapestry to serve some web pages from our google app engine based backend. Some year ago I managed to get 5.3 to work in app engine ... I will be using jquery + bootstrap. I finally got a minimal test project to work but when I switched to jquery by adding c.add(SymbolConstants.JAVASCRIPT_INFRASTRUCTURE_PROVIDER, "jquery") The page raises following js errors Uncaught TypeError: this.element.readAttribute is not a function ElementWrapper.attr @ dom.js:137 (anonymous function) @ console.js:36 context.execCb @ require.js:1665 Module.check @ require.js:874 (anonymous function) @ require.js:1121 (anonymous function) @ require.js:132 (anonymous function) @ require.js:1171 each @ require.js:57 Module.emit @ require.js:1170 Module.check @ require.js:925 (anonymous function) @ require.js:1121 (anonymous function) @ require.js:132 (anonymous function) @ require.js:1171each @ require.js:57 Module.emit @ require.js:1170Module.check @ require.js:925 Module.enable @ require.js:1158 Module.init @ require.js:782 callGetModule @ require.js:1185 context.completeLoad @ require.js:1559 context.onScriptLoad @ require.js:1686 I am also phasing a strange problem in the full project (not in the minimal example) that the page fails to load these assets file: All these fails to be loaded: ===================== admin:20 GET http://localhost:8888/assets/meta/adfea7fc/tapestry5/bootstrap/css/bootstrap.css admin:20 GET http://localhost:8888/assets/meta/8dcee84b/tapestry5/tapestry-console.css admin:20 GET http://localhost:8888/assets/meta/74b3f9bf/tapestry5/tree.css admin:20 GET http://localhost:8888/assets/meta/c81e9337/tapestry5/exception-frame.css admin:60 GET http://localhost:8888/assets/stack/24577ff5/en/core.js admin:20 GET http://localhost:8888/assets/meta/5f95a7ec/tapestry5/tapestry.css admin:60 Uncaught TypeError: require is not a function(anonymous function) @ admin:60 Thanks in advance! /Gunnar
