error appears when i add anything in my controller

[S Shehab]

Hi all ,

i'm using Grails 2.5.1 on Windows 7 64 bit , After generating the controllers and the views using Grails command

generate-all "*"

When i add any new lines in my controllers i get the below error :

Compilation error: startup failed:
E:\Development\eclipse\SherifProjects\TekDays\grails-app\controllers\com\tekdays\TekEventController.groovy: 47: Ambiguous expression could be a parameterless closure expression, an isolated open code block, or it may continue a previous statement;
   solution: Add an explicit parameter list, e.g. {it -> ...}, or force it to be treated as an open block by giving it a label, e.g. L:{...}, and also either remove the previous newline, or add an explicit semicolon ';' @ line 47, column 4.
   			{
      ^
1 error

here is my controller :

package com.tekdays

import static org.springframework.http.HttpStatus.*

@Transactional(readOnly = true)
class TekEventController
{
	def taskService // this what i added
	static allowedMethods = [save: "POST", update: "PUT", delete: "DELETE"]

	def index(Integer max)
	{
		params.max = Math.min(max ?: 10, 100)
		respond TekEvent.list(params), model:[tekEventInstanceCount: TekEvent.count()]
	}

	def show(TekEvent tekEventInstance)
	{
		respond tekEventInstance
	}

	def create()
	{
		respond new TekEvent(params)
	}

	@Transactional
	def save(TekEvent tekEventInstance)
	{
		if (tekEventInstance == null)
		{
			notFound()
			return
		}

		if (tekEventInstance.hasErrors())
		{
			respond tekEventInstance.errors, view:'create'
			return
		}

		tekEventInstance.save flush:true
		taskService.addDefaultTasks(tekEventInstance) // this what i added
		request.withFormat
		{
			form multipartForm
			{
				flash.message = message(code: 'default.created.message', args: [message(code: 'tekEvent.label', default: 'TekEvent'), tekEventInstance.id])
				redirect tekEventInstance
			}
			'*' { respond tekEventInstance, [status: CREATED] }
		}
	}

	def edit(TekEvent tekEventInstance)
	{
		respond tekEventInstance
	}

	@Transactional
	def update(TekEvent tekEventInstance)
	{
		if (tekEventInstance == null)
		{
			notFound()
			return
		}

		if (tekEventInstance.hasErrors())
		{
			respond tekEventInstance.errors, view:'edit'
			return
		}

		tekEventInstance.save flush:true

		request.withFormat
		{
			form multipartForm
			{
				flash.message = message(code: 'default.updated.message', args: [message(code: 'TekEvent.label', default: 'TekEvent'), tekEventInstance.id])
				redirect tekEventInstance
			}
			'*'
			{
				respond tekEventInstance, [status: OK]
			}
		}
	}

	@Transactional
	def delete(TekEvent tekEventInstance)
	{

		if (tekEventInstance == null)
		{
			notFound()
			return
		}

		tekEventInstance.delete flush:true

		request.withFormat
		{
			form multipartForm
			{
				flash.message = message(code: 'default.deleted.message', args: [message(code: 'TekEvent.label', default: 'TekEvent'), tekEventInstance.id])
				redirect action:"index", method:"GET"
			}
			'*'
			{
				render status: NO_CONTENT
			}
		}
	}

	protected void notFound()
	{
		request.withFormat
		{
			form multipartForm
			{
				flash.message = message(code: 'default.not.found.message', args: [message(code: 'tekEvent.label', default: 'TekEvent'), params.id])
				redirect action: "index", method: "GET"
			}
			'*'
			{
				render status: NOT_FOUND
			}
		}
	}
}

Any advice to solve this error ?
