Hi Guys,

We are using WTX node and it needs two inputs. Earlier we planned to use collector node. But Environment Tree was not passed after the collector node.
So, we thought of creating collector like structure using compute node and pass it to WTX node.

Below is my esql code

Quote:

CREATE
Nextsibling of OutputRoot.Properties DOMAIN 'BLOB' Name 'Collection';
SET
OutputRoot.Collection.CollectionName = '';
SET OutputRoot.Collection.IN1 = InputRoot;
SET OutputRoot.Collection.IN2 = Environment.GetReply;

But, I am getting exceptions in WTX node. Below is the output of user trace.

Quote:

UserTrace BIP6068W: A request was made to serialize a bitstream from element ''BLOB'' using parser ''COLLECTION''. The result was zero bytes long.
The node or ESQL ASBITSTREAM function requested that an element serialize its bitstream and this resulted in no bytes being written.
If the output bitstream should not have been zero bytes long, ensure that the correct element was specified.
If the parser name is blank or set to a root parser, associate an owning parser with the element:
If created in ESQL, the DOMAIN clause of the CREATE statement can be used.
If created using the user-defined extension API use a method that allows a parser to be specified.
2010-09-29 16:39:11.577168 6128 UserTrace BIP4150E: User-defined extension input parameter failed debug validation check.
Input parameter 3 passed into function ''cniElementAsBitstream'' does not have a valid value.
Correct user-defined extension implementation accordingly.
2010-09-29 16:39:11.577264 6128 UserTrace BIP2231E: Error detected whilst processing a message in node 'Test_collection.WTX Map'.
The message broker detected an error whilst processing a message in node 'Test_collection.WTX Map'. The message has been augmented with an exception list and has been propagated to the node's failure terminal for further processing.
See the following messages for details of the error.
2010-09-29 16:39:11.577275 6128 RecoverableException DTXMB1004E: WTX for WMB exception {1}:
'cniElementAsBitstream'

Can you guys let me know where I am going wrong.

Thanks
Sam
