Unexpected PushServerException ("Wrong Item Number")

PowerUser

Hi!
I've got a strange issue with the Lightstreamer .Net Client after migration from SimpleTableInfoto ExtendedTableInfo .
When I'm trying to get data from streamer using an ExtendedTableInfoobject Lightstreamer .Net Client throws a PushServerException (with "Wrong Item Number" as message):

2015-08-17 11:57:11,175: Read data: 1,2|402668921|-1|400615766|2441.550000000|0.000000000|2447.450000000|0.000000000|50.0000|6|1|1|\u005C/Date(1439801830000)\u005C/|$|30|true|7|400250261

   at Lightstreamer.DotNet.Client.FullTableManager.DoUpdate(ServerUpdateEvent values)
   at Lightstreamer.DotNet.Client.MyServerListener.OnUpdate(ITableManager table, ServerUpdateEvent values)

When I've used SimpleTableInfo object everything worked fine.
What I'm doing wrong?

Hi,

That's probably because there was an issue moving from SimpleTableInfo to ExtendedTableInfo as while the former expects a group id the latter expects a list of item names. The list of item names is then composed into a group id to be sent to the server by joining all the item names separating them with a white space. Note that for ExtendedTableInfo to be used the Metadata adapter on the server must be able to correctly interpret the group id as composed by the ExtendedTableInfo.

Hope this information will help you solve your issue,
