[rules-dev] rest api - new asset file extension in guvnor

Hi guys, I have a question about creating new assets in Guvnor via rest api, specifically on how to set the file extension of the new asset. My code is simple: URL createURL = new URL(packageAssetsURL); // example url: http://localhost:8080/drools-guvnor/rest/packages/defaultPackage/assets/M... HttpURLConnection createConnection = (HttpURLConnection) createURL.openConnection(); applyAuth(profile, createConnection); createConnection.setRequestMethod("POST"); createConnection.setRequestProperty("Content-Type", "application/octet-stream"); createConnection.setRequestProperty("Accept", "application/atom+xml"); createConnection.setRequestProperty("Slug", assetName); // assetName is for example MyImage createConnection.setDoOutput(true); // apache batik streams the png image data PNGTranscoder t = new PNGTranscoder(); TranscoderInput input = new TranscoderInput(new StringReader(svg)); TranscoderOutput output = new TranscoderOutput(createConnection.getOutputStream()); t.transcode(input, output); The MyImage asset gets created fine in Guvnor under defaultPackage, but the file extension is .txt and not .png If I specify the file extension in the "Slug" request property the file created is for example MyImage.png.txt. Is there any request property or anything else I need to set on the connection to tell guvnor the actual file extension of the new asset?? Any input is much welcome. Thanks.
