hibernate - No value for key bound to thread (Grails) -


i'm developing web application grails. environment specs are:

  • groovy grails tool suite (ggts) 3.6.0.m1-e4.4-win32-x86_64
  • hibernate 4.3.5.3
  • groovy 2.3
  • grails 2.4.0
  • windows 8.1 pro n

i start application, , on grails start page choose controller:

class uploadcontroller {      def index() { }      def upload() {     forward(controller: "parser", action: "takeuploadedfiles")     } }

with controller there not happen anything. corresponding .gsp upload form. use upload multiple files @ once. 

<%@ page contenttype="text/html;charset=utf-8" %> <html> <head> <meta http-equiv="content-type" content="text/html; charset=iso-8859-1"/> <meta name="layout" content="main"/> <title>inhalte einlesen</title> </head> <body>   <div class="body">     <g:uploadform controller="upload" action="upload" autocomplete="off">      <label for="files">bitte alle html-dateien einer kategorie ausw&auml;hlen:</label>     <input type="file" id="files" name="files" multiple="multiple" />     <input type="hidden" id="max_file_size" name="max_file_size" value="30000" />     <g:submitbutton name="add" class="save button medium" value="hochladen" /> </g:uploadform>   </div> </body> </html>

the uploadcontroller forwards parsercontroller. parsercontroller:

import org.springframework.web.multipart.commons.commonsmultipartfile  class parsercontroller {     def multiparttofileservice     def parserservice      def index() { }      def takeuploadedfiles() {        list filelist = request.getfiles('files') // 'files' name of input        filelist.each { file -> multiparttofileservice.convert(file) }         redirect(action: "parse")     }      def parse() {         parserservice.parse()     } }

so upload 1 .html. @ point exception:

2014-06-02 23:04:33,127 [tomcat-http--9] error servlet.grailsdispatcherservlet  - handlerinterceptor.aftercompletion threw exception java.lang.illegalstateexception: no value key [org.hibernate.internal.sessionfactoryimpl@6398813a] bound thread [tomcat-http--9]     @ grails.plugin.cache.web.filter.pagefragmentcachingfilter.dofilter(pagefragmentcachingfilter.java:198)     @ grails.plugin.cache.web.filter.abstractfilter.dofilter(abstractfilter.java:63)     @ java.util.concurrent.threadpoolexecutor.runworker(threadpoolexecutor.java:1145)     @ java.util.concurrent.threadpoolexecutor$worker.run(threadpoolexecutor.java:615)     @ java.lang.thread.run(thread.java:745)

this exception doesn't stop application, parsing done perfectly. don't understand exception, , found out might have transactional services i'm injecting in pasercontroller. whithout service injection, don't exception (instead missingpropertyexception, of course):

import org.springframework.web.multipart.commons.commonsmultipartfile  class parsercontroller { //  def multiparttofileservice //  def parserservice      def index() { }      def takeuploadedfiles() {     list filelist = request.getfiles('files') // 'files' name of input         filelist.each { file -> multiparttofileservice.convert(file) }          redirect(action: "parse")     }      def parse() {         parserservice.parse()     } }

any ideas how avoid illegalstateexception?

this seems problem: https://github.com/grails/grails-core/issues/2105

commonjs - How to write a typescript definition file for a node module that exports a function? -

consider, toml node module can use: // toml.d.ts declare module toml { export function parse(value:string):any; } declare module "toml" { export = toml; } then: /// <reference path="../../../../../defs/toml/toml.d.ts"/> import toml = require('toml'); toml.parse(...); however, node module export single function, such 'glob' ( https://github.com/isaacs/node-glob ). the node usage of module be: var glob = require("glob") glob("*.js", {}, callback(err, files) { ... }); you'd naively expect this: // glob.d.ts declare function globs(paths:string, options:any, callback:{(err:any, files:string[]):void; ...but because typescripts 'import' semantics bit strange, seems can use 'import .. = require()' statement alias modules . trying call: /// <reference path="../../../../../defs/glob/glob.d.ts"/> import blog = require('glob'); results in: error ts2072: mod...
