Subject: about CSS BOY

      I meet some problem while using CSS. The problem is when I use PVUtil.getDouble() to get the value of some PV, there will be ERROR in BOY console if the PV is disconnected. An example ERROR information is "2014-05-04 17:12:48 ERROR: Error exists in script/CSS/_javascript_/ECR_Print.js Wrapped java.lang.RuntimeException: PV SSC-LINAC:ECR:AGL-BEAM has no value. (script#23)". How can I check the connecting state in _javascript_ code before I use PVUtil.getDouble()?
