Deployment overrides java code

When I change my java action (Project folder -> Javasource -> folder -> actions -> it seems to change back whenever I deploy my application. I have also tried changing the code in Eclipse and saving it, but still whenever I deploy my application the code changes back to the previous version. What am I missing here? Am i changing the code in the wrong location?   // This file was generated by Mendix Modeler. // // WARNING: Only the following code will be retained when actions are regenerated: // - the import list // - the code between BEGIN USER CODE and END USER CODE // - the code between BEGIN EXTRA CODE and END EXTRA CODE // Other code you write will be lost the next time you deploy the project. // Special characters, e.g., é, ö, à, etc. are supported in comments. package webservice_ntlm.actions; import; import; import; import; import; import javax.xml.parsers.DocumentBuilder; import javax.xml.parsers.DocumentBuilderFactory; import javax.xml.transform.OutputKeys; import javax.xml.transform.Transformer; import javax.xml.transform.TransformerFactory; import javax.xml.transform.dom.DOMSource; import; import; import org.apache.http.HttpEntity; import org.apache.http.HttpHost; import org.apache.http.HttpResponse; import org.apache.http.auth.AuthScope; import org.apache.http.auth.NTCredentials; import org.apache.http.client.AuthCache; import org.apache.http.client.CredentialsProvider; import org.apache.http.client.methods.HttpPost; import org.apache.http.client.protocol.HttpClientContext; import org.apache.http.entity.StringEntity; import org.apache.http.impl.auth.NTLMScheme; import org.apache.http.impl.client.BasicAuthCache; import org.apache.http.impl.client.BasicCredentialsProvider; import org.apache.http.impl.client.CloseableHttpClient; import org.apache.http.impl.client.HttpClientBuilder; import org.apache.http.util.EntityUtils; import org.w3c.dom.Document; import org.w3c.dom.Node; import org.w3c.dom.NodeList; import org.xml.sax.InputSource; import com.mendix.core.Core; import com.mendix.systemwideinterfaces.core.IContext; import com.mendix.webui.CustomJavaAction; import com.mendix.systemwideinterfaces.core.IMendixObject; public class NTLM_WebService extends CustomJavaAction<Boolean> { private IMendixObject __Request; private system.proxies.FileDocument Request; private IMendixObject __Response; private system.proxies.FileDocument Response; private String SoapUrl; private String SoapAction; private IMendixObject __Config; private webservice_ntlm.proxies.NTLM_Config Config; public NTLM_WebService(IContext context, IMendixObject Request, IMendixObject Response, String SoapUrl, String SoapAction, IMendixObject Config) { super(context); this.__Request = Request; this.__Response = Response; this.SoapUrl = SoapUrl; this.SoapAction = SoapAction; this.__Config = Config; } @Override public Boolean executeAction() throws Exception { this.Request = __Request == null ?

EDIT 1:  That is a more complex scenario. This happens when you import/create an entity with the same name as a Parameter. Mendix will rename the parameter by adding 'parameter1' to it. Please rename the parameter before importing or creating the entity by starting with a lowercase character ('response' instead of 'Response) and change use of the parameter in the java-action. Check for syntax errors. After that import the module again.

In my project entities start with a capital, java-action parameters start with a lowercase character.

I mentioned lowercase but you can use any naming convention to prevent renaming.

IMHO Mendix would be helpful by raising a warning on using parameters with an entityname.
