#44 DataSelector.getAllTagFieldNames bug

[Wang Yun]

create TagField named "tf1"
create TagField named "tf2"
create DataSelector named "ds1"
add tf1 and tf2 to ds1
Call DataSelector.getAllTagFieldNames, the expected value is 2, but actual get 0

xml request sequences are as follows:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<ns2:command xmlns:ns2="urn:epcglobal:rp:xsd:1">
<id>18</id>
<targetName></targetName>
<tagField>
<create>
<name>tf1</name>
</create>
</tagField>
</ns2:command>

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<ns2:command xmlns:ns2="urn:epcglobal:rp:xsd:1">
<id>18</id>
<targetName></targetName>
<tagField>
<create>
<name>tf2</name>
</create>
</tagField>
</ns2:command>

<ns2:command xmlns:ns2="urn:epcglobal:rp:xsd:1">
<id>20</id>
<targetName></targetName>
<dataSelector>
<create>
<name>ds1</name>
</create>
</dataSelector>
</ns2:command>

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<ns2:command xmlns:ns2="urn:epcglobal:rp:xsd:1">
<id>22</id>
<targetName>ds1</targetName>
<dataSelector>
<addTagFieldNames>
<fieldNames>
<list>
<value>tf1</value>
<value>tf2</value>
</list>
</fieldNames>
</addTagFieldNames>
</dataSelector>
</ns2:command>

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<ns2:command xmlns:ns2="urn:epcglobal:rp:xsd:1">
<id>24</id>
<targetName>ds1</targetName>
<dataSelector>
<getAllTagFieldNames/>
</dataSelector>
</ns2:command>

at last we get the wrong response:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<ns2:reply xmlns:ns2="urn:epcglobal:rp:xsd:1">
<id>24</id>
<resultCode>0</resultCode>
<dataSelector/>
</ns2:reply>
