+************************************************************************** + +From this wsdl I've created a client stub with Mono "wsdl" tools. When +using this stub class a System.InvalidCastException is raised when the stub +remote function getTagIdList is called. Note that all other remote +functions work without a glitch. + +The transfered object in the getTagIdList fuction is a "dynamic array of +struct" ("TagIdList" in the wsdl file). This kind of object seems to be +poorly supportded in SOAP implementations other than gSOAP. + +I've also generated the stub with MS.Net tools. The MS.Net generated class +was simmilar but raised no exception. On the other hand MS.Net generated +stub did not receive the array correctly either, it always receive a null +array but the "scanning" parameter is received correctly. + +I've sniffed the HTTP packets during the array transfert and I've seen that +the array seems to be correcty serialised and is not empty : +************************************************************************** +0000 00 0e a6 9e 8a 6a 00 14 fb 00 00 33 08 00 45 00 .....j.. ...3..E. +0010 03 e0 4a 6b 40 00 40 06 68 28 c0 a8 01 ea c0 a8 [EMAIL PROTECTED]@. h(...... +0020 01 4a 1f 90 e1 e0 78 9e d1 5a ed 97 c4 f2 80 18 .J....x. .Z...... +0030 0f 80 56 0f 00 00 01 01 08 0a 00 7e 9b 24 05 3c ..V..... ...~.$.< +0040 06 57 48 54 54 50 2f 31 2e 31 20 32 30 30 20 4f .WHTTP/1 .1 200 O +0050 4b 0d 0a 53 65 72 76 65 72 3a 20 67 53 4f 41 50 K..Serve r: gSOAP +0060 2f 32 2e 37 0d 0a 43 6f 6e 74 65 6e 74 2d 54 79 /2.7..Co ntent-Ty +0070 70 65 3a 20 74 65 78 74 2f 78 6d 6c 3b 20 63 68 pe: text /xml;
