Hi Godwin,
You can try below-mentioned way to pass the null value correctly to the
data service. IMO, We need to fix this issue. It's not correct to evaluate
JSON null value as String "null"
<filter xpath="string(get-property('Id')) != 'null'">
<then>
<payloadFactory media-type="xml">
<format>
<m1:updateForOperation xmlns:m1="http://www.test.com.";>
<m1:iId>$1</m1:iId>
<m1:iBitrixDealId>$2</m1:iBitrixDealId>
<m1:iBitrixContractId>$3</m1:iBitrixContractId>
</m1:egateUpdateForBitrixOperation>
</format>
<args>
<arg evaluator="xml" expression="get-property('Id')"/>
<arg evaluator="xml" expression="get-property('DealId')"/>
<arg evaluator="xml"
expression="get-property('ContractId')"/>
</args>
</payloadFactory>
</then>
<else>
<payloadFactory media-type="xml">
<format>
<m1:updateForOperation xmlns:m1="http://www.test.com.";>
*<m1:iId
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance
<http://www.w3.org/2001/XMLSchema-instance>" xsi:nil="true"/>*
<m1:iBitrixDealId>$1</m1:iBitrixDealId>
<m1:iBitrixContractId>$2</m1:iBitrixContractId>
</m1:egateUpdateForBitrixOperation>
</format>
<args>
<arg evaluator="xml" expression="get-property('DealId')"/>
<arg evaluator="xml"
expression="get-property('ContractId')"/>
</args>
</payloadFactory>
</else>
</filter>
Thanks,
Madhawa
