Setup Xpand workflow: No Definition 'MyTemplate::main ...' found! [message #777597]

Tue, 10 January 2012 14:43

Eclipse User

Hello!

I am trying to set up an Xpand workflow but the following exception is raised instead.

0    ERROR AbstractExpressionsUsingWorkflowComponent - Error in Component  of type org.eclipse.xpand2.Generator: 
	EvaluationException : No Definition 'MyTemplate::main for pointPath::Model' found!

I reduced my setup to the following files (paths are relative from workspace root '/'), but the problem still persists.
(Assume that I am stupid and don't know anything.)

[/CodeGenerators/src/blub.mwe2]

module blub

Workflow {

	component = org.eclipse.xtext.mwe.Reader {
		path = "../LegoExamples/input"
		register = tue.glt.lego.points.PointPathStandaloneSetup {}
		load = {
			slot = "xxx"
			type = "Model"
		}
	}

	component = org.eclipse.xpand2.Generator {
		metaModel = org.eclipse.xtend.typesystem.emf.EmfMetaModel {
			metaModelPackage = "tue.glt.lego.points.pointPath.PointPathPackage"
		}
		expand = "MyTemplate::main FOREACH xxx"
		outlet = {
			path = "../LegoExamples/output"
		}
	}
}

[/CodeGenerators/src/MyTemplate.xpt]

«IMPORT tue::glt::lego::points::pointPath»

«DEFINE main FOR Model»
«ENDDEFINE»

[/DslProject/src/tue/glt/lego/points/PointPath.xtext]

grammar tue.glt.lego.points.PointPath with org.eclipse.xtext.common.Terminals

generate pointPath "h t t p ://www.glt.tue/lego/points/PointPath"  // (cannot post links)

Model:
	name = ID
;

I would really appreciate your help because I am fighting this for almost a whole day now (Google was not much help either) and getting quite desperate.

Thanks for your time!

Hi, in the workflow file you use the emf metamodel but the Imports
in the xpand file wäre javabeansmetamodel style.

hi,

lets say you created a new Xtext project with the wizard then

the imports in javabeans metamodel style are org::xtext::example::mydsl::myDsl
the imports in the emf (registry) metamodel style are myDsl

you can configure the metamodel you use in your projects Xpand/Xtend properties and in the Workflow Component e.g. the Generator.

My workflow file:

module run

import org.eclipse.emf.mwe.utils

var inputDir = "src/instances"
var targetDir = "src/output"

Workflow {
	component = org.eclipse.xtext.mwe.Reader {
		path = inputDir
		register = org.xtext.CommandsStandaloneSetup {}
		load = {
			slot = "someslot"
			type = "Model"
			name = "outputa"
		}
	}
	
	component = org.eclipse.xpand2.Generator {
		expand = "templates::commands2txtnxt::generateFile FOR someslot"
		outlet = {
			path = targetDir
		}
	}
}

and this is my template

«IMPORT org::xtext::commands»

«DEFINE generateFile FOR Model»

«ENDDEFINE»

Very basic stuff, but I have no idea how to fix this. I have exported the xtext as a plugin, so the import in the template file is ok.

Hi

there are error messages so you should follow them

first someslot contains a list so you should
(1) change the call to templates::commands2txtnxt::generateFile FOREACH someslot or
(2) change the template to DEFINE generateFile FOR List[Model]

but first of all you should take of Could not find any exported element of type 'Model' -> Slot 'someslot' is empty.
=> a forum search should help you to solve this common error

I found your answer that you have to put this somewhere

public class MyDslNameProvider extends DefaultDeclarativeQualifiedNameProvider {

    QualifiedName qualifiedName(Model m) {
        return QualifiedName.create(m.eResource().getURI().toString());
    }
}

public class MyDslRuntimeModule extends
                          org.xtext.example.mydsl.AbstractMyDslRuntimeModule {

    @Override
    public Class<? extends IQualifiedNameProvider> bindIQualifiedNameProvider() {
        return MyDslNameProvider.class;
    }   
}

It is probably a stupid question, but I just don't know where?!

I tried everything, searched for the forum and other sites and still I can't fix it.

The error is now "only":

0    WARN  SlotEntry          - Could not find any exported element of type 'Model' -> Slot 'someslot' is empty.
26   INFO  Workflow           - Done.

My workflowfile

module run

import org.eclipse.emf.mwe.utils

var inputDir = "src/instances"
var targetDir = "src/output"

Workflow {
	component = org.eclipse.xtext.mwe.Reader {
		path = inputDir
		register = org.xtext.CommandsStandaloneSetup {}
		load = {
			slot = "someslot"
			type = "Model"
			name = "outputa"
		}
	}
	
	component = org.eclipse.xpand2.Generator {
		expand = "templates::commands2txtnxt::generateFile FOREACH someslot"
		metaModel = org.eclipse.xtend.type.impl.java.JavaBeansMetaModel {}
		outlet = {
			path = targetDir
		}
	}
}

I found on stackoverflow the same question. Christian, you answered with the Java snippet of code as a solution, but I don't know where to put it.

Another solution that is presented there, which seems a little bit neater, is

Quote:

Probably the best way is inserting the text {Model} just at the beginning of the rule, to ensure the creation.

but where do I have to put this exactly? I tried adapting the rule

Model : (paths += Path)*;

into

Model : {Model} (paths += Path)*;

recompiled and exported the plugin, but with still no success.

Anyone here that has any ideas? I'm busy with these problems for days.

Hi,

the reader collects only elements that have a "name" and can thus be referenced. Your model doesn't have one. A search for "xtext model slot empty" should reveal several solutions as that is a common question.

Christian already gave one explicit way. Implement a name provider (new class to be put into your project) and bind it in the runtime module (there is a pre-generated class where you add the given binding).

good evening,
I generated a model xmi after the execution of workflow engine "mydslGenerator.mwe2" but I can not open it .. I lived this problem:

"org.eclipse.xtext.mwe.SlotEntry - Could not find any element of type Exported 'BINDING' -> Slot 'BINDING' is empty."

the "BINDING" is the slot .
the code of "mydslGenerator.mwe2" was :

module workflow.LfGenerator

import org.eclipse.emf.mwe.utils.*
import org.xtext.lf
import  org.eclipse.xtend  
import  org.eclipse.xtext 

var targetDir = "src-gen"
var fileEncoding = "ISO-8859-1"
var modelPath = "src/model"

Workflow {

          bean =org.eclipse.emf.mwe.utils.StandaloneSetup{
        	platformUri=".." }
	component = org.eclipse.xtext.mwe.Reader {
		// lookup all resources on the classpath
		// useJavaClassPath = true

		// or define search scope explicitly
		path = modelPath

		// this class will be generated by the xtext generator 
		register = org.xtext.LfStandaloneSetup {}
		load = {
			slot = "BINDING"
			type = "BINDING"
		}
	}

	component = org.eclipse.xpand2.Generator {
		 metaModel = org.eclipse.xtend.type.impl.java.JavaBeansMetaModel {}
		   expand = "templates::Template::main FOREACH     BINDING"
				outlet = {
			path = targetDir
		}
		fileEncoding = fileEncoding
	}
	
	//--générer le modèle-
	component = org.eclipse.emf.mwe.utils.Writer{
       modelSlot ="BINDING"
       uri ="${targetDir}/example.xmi"}
	
	
	
}

pleaaaaaaaaaase help me !

Please help me

I'm stuck in this stage.

Hi,

seems there are no BINDINGs written to the index by your model.
please make sure you have a metatype BINDING with a name attribute. if not fix this by
(a) chaning the metamodel
(b) a custom IQualifiedNameProvider
(c) a custom IDefaultResourceDescriptionStrategy

Hi not find. create! e.g.

	}

}

public class MyDslRuntimeModule extends org.xtext.example.mydsl.AbstractMyDslRuntimeModule {

Hi,

i am confused by your question. could yoiu please explain step by step what you are actually doing in you usecase.
here is what i asumed

(1) you have a Xtext project that defines a Lf Language (please share you grammar)
(2) there Language defines a Concept "BINDING"
(3) you have some of these .yourdsl file lying arround and want to generate code from them
(4) you create the MyQNP class somewhere in yourdsls runtime project
(5) you adapt the existing runtime module class in your dsls runtime project and add the binding there

P.S: which Xtext Version do you use?

Hi,

your sample model is still missing. btw why do you want to use xtext for such xmlish stuff (maybe you should have a look at xsd2ecore

And:

i do the following

(1) create a new xtext project using the wizard
(2) paste your grammar
(3) Generate the language
(4) adapt the workflow in the generator project
(5) drop following Example.mydsl file into the src/model dir

<definitions  name="test" targetNamespace="test">
<binding name="test" type="test" >
<soap:binding style="style" transport="test"
/>
<operation name="test" >
<soap:operation soapAction="test" />
<input>
<soap:body use="test" encodingStyle="test"
 />
 </input>
 <output>
 <soap:body use="test"
 encodingStyle="test"
 />
 </output>
 </operation>
 </binding>
 </definitions>

(6) run the workflow.

an hey: it works without any complaints

hi ,
I create a new project xtext .
I pasted the grammar .
and i changed the file example with :

<definitions  name='test' targetNamespace='test'>
<binding name='test' type='test'>
<soap:binding style='style' transport='test'/>
<operation name='test' >
<soap:operation soapAction='test' />
<input>
<soap:body use='test' encodingStyle='test' />
 </input>
 <output>
 <soap:body use='test'
 encodingStyle='test'/>
 </output>
 </operation>
 </binding>
 </definitions>

but when I run the workflow . I got those errors:

<definitions  name='test' targetNamespace='test'>
<binding name='test' type='test'>
<soap:binding style='style' transport='test'/>
<operation name='test' >
<soap:operation soapAction='test' />
<input>
<soap:body use='test' encodingStyle='test' />
 </input>
 <output>
 <soap:body use='test'
 encodingStyle='test'/>
 </output>
 </operation>
 </binding>
 </definitions>

I'm doing a project on transforming " text into wsdl model" (T2M). that's why I'm doing a project on xtext to build the wsdl grammar (1). I "run" to end the workflow to generate a model consistent with the meta-xmi model wsdl.

P.S:

maybe there is some config missing to the org.eclipse.emf.mwe.utils.Writer component.
why did you add addional stuff to a workflow that was not working? why do you want to use the writer component at all? i dont know if it works with a list of models.

Hi,

this behavour is expected!!!!!!!!!!!!!!!!!!!!!!!!!!!! you HAVE to install your dsl plugins into your eclipse or start a runtime eclipse
to get it running: since the xmi uses namespaces!!!!!!!!!!!!!!! it does not know the ecore file lying arround here and there.
