I found the solution. I add the js files to my stack in the getJavaScriptLibraries method depending of a parameter of my request.
public List getJavaScriptLibraries() { List jsStack = new ArrayList(); if (myRequest.getMyParam) { jsStack.add(customMessages); } return jsStack; } But when the StackAssetRequestHandler service call this method, I lost this parameter, so Tapestry include any file. My final JS file is empty. I extended the StackAssetRequestHandler class. I set again my param in the handleAssetRequest method, depending of the desired Stack name. public boolean handleAssetRequest(Request request, Response response, String extraPath) throws IOException { if(extraPath.endsWith("myStack.js")) myRequest.setMyParam(true); return super.handleAssetRequest(request, response, extraPath); } Thanks Emmanuel -- View this message in context: http://tapestry.1045711.n5.nabble.com/JavaScript-Stack-aggregator-tp3403611p3407618.html Sent from the Tapestry - User mailing list archive at Nabble.com. --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tapestry.apache.org For additional commands, e-mail: users-h...@tapestry.apache.org
