Is it a bug in the JQuery xhr.abort() then? Debugging RequestFilter.service I found that request.request.request._connection._parser._state = -13 ( org.mortbay.jetty.HttpParser.STATE_START) when things goes wrong (Should be org.mortbay.jetty.HttpParser.STATE_CONTENT). I did not figure out how I can test on this value, so I change my JavaScript code:
owner.simplifyPolylineLastCallCnt = 0; owner.simplifyPolyline = function (tolerance) { owner.simplifyPolylineLastCallCnt++; var callId = owner.simplifyPolylineLastCallCnt; $.post("/map/client/trackdraw:DouglasPeuckerSimplifier", { }).done(function (data) { if (callId != owner.simplifyPolylineLastCallCnt) return; // DO THE WORK Now I can set onDouglasPeuckerSimplifier back to allowBlank = false and skip the == null test :-) Forgot to tell that I am running Tapestry 5.4-beta-26. *From:* Lance Java [via Apache Tapestry Mailing List Archives] [mailto: ml-node+s1045711n5730599...@n5.nabble.com] *Sent:* 7. mai 2015 11:39 *To:* Svein *Subject:* Re: Detect jqXHR.abort() The server will know about an aborted request as it's too late, the request has already been sent. Abort is a clientside concept AFAIK which stops the client from waiting for the response / processing it. ------------------------------ *If you reply to this email, your message will be added to the discussion below:* http://apache-tapestry-mailing-list-archives.1045711.n5.nabble.com/Detect-jqXHR-abort-tp5730595p5730599.html To unsubscribe from Apache Tapestry Mailing List Archives, click here <http://apache-tapestry-mailing-list-archives.1045711.n5.nabble.com/template/NamlServlet.jtp?macro=unsubscribe_by_code&node=2375124&code=c3ZlaW5AamFjaWxsYS5ub3wyMzc1MTI0fC0xNTM4NzY2ODg4> .
