stitches, my grails-based project has an example client that uses the groovyws to connect to the soap services that stitches exposes.  I have tests that invoke, "push, pull, prod" the web services to do all kinds of things.   However, on a very regular basis, I was getting the following perplexing error:

What was perplexing was that I was able to create a class with this same proxy in another test.  While I don't understand why this error is generated, I figured out a workaround.  Do not create multiple proxy objects.  That is, if you create a proxy in your Integration Test, don't create another one in your controller, pass the proxy to the controller from your test, and things will work.  I am guessing that the classes that are generated by a Thread or classloader are private to that Thread/classloader.

Here is an example of my integration test, I am passing my groovyws proxy:

		void testSaveExistingTag() {
		Long tagId = helper.getTagId(name:"testSaveExistingTag")
		def controller = new TagsController()	
		controller.helper = helper
		controller.request.parameters = ['name':"testSaveExistingTag2",id:tagId.toString()]
		controller.saveTag()  
		//let's verify it worked
		def tagHolder = helper.findTagById(tagId)
		assertTrue tagHolder.name == 'testSaveExistingTag2'
			
	}




Here is my controller:




	
	def helper = null
	
	def getHelper() {
		if (helper == null) {
			helper = new Helper()
		}
		return helper
	}

	def saveTag = { 
			def proxy = getHelper().getProxy()
		def tagRequest = proxy.create("org.authsum.stitches.external.TagRequest")
		
		def tagHolder = proxy.create("org.authsum.stitches.external.TagHolder")
		
		if (!tagRequest.tagHolders) {
			def tagHolders = proxy.create("org.authsum.stitches.external.ArrayOfTagHolder")
			tagRequest.tagHolders = tagHolders
			tagRequest.tagHolders.tagHolder.add(tagHolder)
		}		 
		bindData(tagHolder, params)
						//TEMP, need to set the id manually
				if (params['id']) {
				tagHolder.id = params['id'].toLong()
				}
				
				
		def response =proxy.saveTag(tagRequest)
		
		assert response.responseCode == '200'
		flash.message = 'tag saved'
		
		chain(action:index)
		
		
		
	}
