error on ListGrid.getCurrentCheckboxField

[itb]

I'm using smartGWT LGPL 2.2. During startup of our application I see the following stacktrace in the GWT console:

XRP2:WARN:Log:TypeError: _1 is undefined

    RPCManager._performTransactionReply(3)
    [c]RPCManager.performTransactionReply(_1=>3,  _2=>"<response>\n  <status>0</status>\n  <st..."[ 134],  _3=>undef)
    anonymous(3, [object XMLHttpRequest])
    [c]Class.fireCallback(_1=>"isc.RPCManager.performTransactionReply(..."[ 67],  _2=>"transactionNum,results,wd",  _3=>[object Array])
    [c]Comm.performXmlTransactionReply(_1=>3,  _2=>[object XMLHttpRequest])
    anonymous([object XMLHttpRequest])
    [c]Class.fireCallback(_1=>"isc.Comm.performXmlTransactionReply(3, ..."[ 56],  _2=>"xmlHttpRequest",  _3=>[object Array],  _4=>[object XPCCrossOriginWrapper],  _5=>true)
    Comm._fireXMLCallback([object XMLHttpRequest], "isc.Comm.performXmlTransactionReply(3, ..."[ 56])

Many things happen during startup and I'm not sure which callback exactly causes this, but I think this is on a TreeGrid and the server response contains no records. I've been unable to pinpoint it because it never reaches my own code.

how can I prevent this?

thanks,
