Why do I receive an error when calling certain methods of my Web Service?

When I call certain methods of my Web Service, I sometimes receive an error similar to the following:

 ??? Subscripted assignment between dissimilar structures.

 Error in ==> parseSoapResponse>convert at 77

                 s.(name)(end+1,1) = value;

 Error in ==> parseSoapResponse at 48

     result{end+1} = convert(resultChild);

 Error in ==> service1.getdata at 26

 results = parseSoapResponse(response);

This bug has been fixed in Release 14 Service Pack 2 (R14SP2). For previous releases, please read below for any possible workarounds:

This has been verified as a bug in the Web Services interface in MATLAB 7.0 (R14). A workaround exists if you can change the results returned by the Web Service.

This particular error is caused by a parent tag in the XML returned by the method that does not have the same number of children in all instances. For example:

 <parent>

    <child1/>

    <child2/>

 </parent>

 <parent>

    <child1/>

 </parent>

If each parent had two children (with the same names), the error would not occur.
