Hi, I tried to pass a parameter from within a JS-Framework to DSS 2.5.0. Use Case: when pressing a button, a product with the specific "productCode=RTS_003" is to be be deleted. In the framework the parameter is generated as : /serviceURL/resource_path/?productCode=RTS_003 DSS throws an exception: ... Default Namespace: http://ws.wso2.org/dataservice Current Request Name: _deleteproductrem_productcode Current Params: {productCode={productCode,RTS_003}} Nested Exception:- Scalar type expected Current Params: {productCode={,RTS_003}} Field Name: productCode Field Value: {,RTS_003} ... Instead of "RTS_003" the parameter value is interpreted as {,RTS_003}. Here a piece of the DSS Data Service definition file: delete Products where productCode=? What is my error ? Does'nt DSS understand the Parameter notation: /serviceURL/resource_path[/?parameter1=parameter_value1[&parameter2=parameter_value2][&...]] and must have ?: /serviceURL/resource_path[/parameter_value1[/parameter_value2][/...]] Regards -------------------- Because my "piece of the DSS Data Service definition file:" (see above) has been "swallowed" by the Drupal-CMS I have attached the whole DSS-Definition as a file. Regards

Check the parameter notations

Submitted by kalpanie on August 2, 2010 - 21:06.
Hi, Could you pls check this, by passing the parameters as follows. Eg: /serviceURL/resource_path/parameter_value1/parameter_value2 You don't need to use '?' mark. Since you have mentioned the parameter order in the data service, when you creating the resource (), you just have to pass the parameter values by separating them by the slashes. (parametervalue1/parameterValue2). Thanks. Kalpanie

URI-template syntax ... tryit bug

Submitted by manfred.herrman... on August 11, 2010 - 07:00.
@Kalpanie Ralf talks about a "javascript-framework". This requires the not so RESTful URL-parameter syntax. What I tried with configuring dataservices, it is possible to define resources with "?parameter=value". And of course the ideal RESTful "resource-path syntax" is working too. The "?" is a URI-template pattern and this is supported by WSO2-DSS, right? I defined resources with "?parameter=value"-syntax. The http-methods (get/put/post/delete) are doing o.k. but the tryit-client is broken. best regards manfred
