BUG? For nodes containing @ JSONPath Match works differently in SoapUI and SoapUI NG

We have names of the id fields starting with "@" char and each item created has existence check on that field.

JSONPath:          $.bean.@id

Expected result:  true

In Soap UI Pro 5.1.2 the "Select current value" function auto-completes with "true".

In Ready!API 1.7.0 SoapUI NG the same operation auto-completes with "false".

Also, the test steps from the test cases that are following are using the ID value. Using "Get Data" option, the @id element can be selected from a previously executed step but when executed it is resolved to null value.

For example, having a POST that has ($.bean.@id) in response, followed by a GET that uses the id:

(${POST - addItem#Response#$.bean.@id})

will result in executing the request:

GET http://localhost:6080/rest/v1/application/.... /item/null HTTP/1.1

Is there a workaround for this issue?

Thanks,

Ionut
