I am trying to connect to a simple webservice, however getting an error when trying to connect to it. The webservice will give back a conversion rate from one currency to another, and is located at: http://www.webservicex.net/CurrencyConvertor.asmx?WSDL The stack trace error i'm getting is : An error has occurred while handling the request. [User 'Cedric' with roles 'SuperRequester'] com.mendix.core.CoreException: Exception occurred in action 'Microflow [MyFirstModule.UpdateCurrencies]', all database changes executed by this action were rolled back at com.mendix.core.actionmanagement.CoreAction.d(SourceFile:553) Caused by: com.mendix.core.CoreException: Exception occurred in microflow 'MyFirstModule.UpdateCurrencies' for activity 'NestedLoopedMicroflow', all database changes executed by this microflow were rolled back at kP.b(SourceFile:251) Caused by: com.mendix.core.CoreException: Exception occurred in microflow 'MyFirstModule.UpdateCurrencies.nested.60304' for activity 'Call web service 'ConversionRate'', all database changes executed by this microflow were rolled back at kP.b(SourceFile:251) Caused by: org.apache.axiom.om.OMException: localname can not be null or empty at org.apache.axiom.om.impl.llom.OMElementImpl.<init>(OMElementImpl.java:122) at org.apache.axiom.om.impl.llom.OMElementImpl.<init>(OMElementImpl.java:138) at org.apache.axiom.om.impl.llom.factory.OMLinkedListImplFactory.createOMElement(OMLinkedListImplFactory.java:95) at hv.a(SourceFile:64) at ki.a(SourceFile:32) at lJ.a(SourceFile:170) at lJ.a(SourceFile:69) at com.mendix.modules.webservices.WebserviceModule.callWebservice etc. etc. Does someone have an idea of what this could mean?

Hi Erdal,
Can you provide us with some more information on the exact actions you are performing in your microflow?
As I tried the following for the mentioned webservice:
Created an entity Currencies with overview and new edit forms.
Attributes: 2 currency type attributes: From and To
2 string attributes: Fromtype and to type
On the edit form added MF-button calling a convert MF.
Imported the webservice.
Created a MF that calls the webservice using the 2 string attributes as the parameters. From the webservice call I get the conversion rate back as a float. Then in a second action I change the to field by setting it to $Currencies/From*$ConversionRate.
This works like a charm.
Is this what you tried or did you try something different?
