Is there a limit to XPath complexity in SOATest?

I have the following json response from a call that I am looking to evaluate certain fields on before making the second call, but when I build out the xpath with more than 3 conditional checks, the viewer for that databank bank entry fails to evalute or open again, once closed

{
    "txnId" : "90f2ef78-3223-4069-b26d-bd9c496290a9",

        }
    }
}

Xpath in Databank that works fine

boolean(/root/device[deviceState/text()="CONNECTED_UNPAUSED"][connectionType/text()="WIFI"][wifiRadioFrequency/text()!="2.4"])

Adding 4th clause for evaluation cause the viewer to not open or evaluate

boolean(/root/device[deviceState/text()="CONNECTED_UNPAUSED"][connectionType/text()="WIFI"][wifiRadioFrequency/text()!="2.4"][radioFrequenciesSupported/radio24=true])

Is this a known issue or new found bug? Is there a work around?

Is this a known issue or new found bug?

It looks like an issue in the Saxon library which is throwing a runtime exception when trying to parse that particular XPath.

Is there a work around?

Please correct the last clause to [radioFrequenciesSupported/radio24/text()="true"]

Is there a limit to XPath complexity in SOATest?
