    <p>This is a pretty odd situation I have here. I have used a piece of code to interact with a backend SOAP service for several months - it works fine. I tried it out in a different project (first as an swc library and then just by cutting and pasting) and it just doesnt work.</p> <p>If I try the exact same code in the original flex project, connecting to the same backend service, everything works fine. In the new project, I can call operations that take simple document-literal wrappers as params (they have no real parameters) - but if the operation has a complex parameter inside the document literal wrapper - fail on this new project. Here is a sample that would fail:</p> <pre><code>var service:WebService = new WebService(); service.wsdl = wsdlURL; var operation:AbstractOperation = service.getOperation( "addNewUser" ); var param:XML = &lt;AddNewUserRequest/&gt; param.setNamespace( myNameSpace ); param.user.username( username ); param.user.email( email ); operation.send( param ); </code></pre> <p>And here is a sample that would work in the new project:</p> <pre><code>var service:WebService = new WebService(); service.wsdl = wsdlURL; var operation:AbstractOperation = service.getOperation( "getUsers" ); var param:XML = &lt;GetUsersRequest/&gt; param.setNamespace( myNameSpace ); operation.send( param ); </code></pre> <p>Here are some things that I have done to try an track this one down:</p> <p>-Examined the posts in firebug from both projects and can not see a difference (meaning that the code appears to generate the exact same SOAP request in both projects (as one expects) -I have verified that the requests should work using SOAPui to directly query the web service</p> <p>The back end service is an Apache CXF webservice and here is a sample of the error it generates:</p> <blockquote> <p>org.apache.cxf.interceptor.Fault: Found element {<a href="http://www.w3.org/2001/XMLSchema" rel="nofollow noreferrer">http://www.w3.org/2001/XMLSchema</a>}user but could not find matching RPC/Literal part</p> </blockquote> <p>Everything I know leads me to believe that user should be in the <a href="http://www.w3.org/2001/XMLSchema" rel="nofollow noreferrer">http://www.w3.org/2001/XMLSchema</a> namespace - and honestly - I believe the key here is that the code works in one project but not in the other. Could it be an XML setting? One of the static ones like ignoreWhitespace? I have played with changing those around - with no luck.</p> <p>Any ideas at all? This is driving me crazy!!!</p> <p>UPDATE:</p> <p>I have narrowed it down to this: the new project creates a header like this:</p> <pre><code>&lt;SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"&gt; </code></pre> <p>and the one that works creates this:</p> <pre><code>&lt;SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"&gt; </code></pre> <p>Why the difference on the exact same version of flex &amp; flex builder? The one that works is obviously correct (xmlns:xsd="http://www.w3.org/2001/XMLSchema") - the web service is correct to reject a request that puts everything in the request in the xsd namespace.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
