Hi

After seeing the latest 'Builder' CSS and Kay's emails to me, I decided to go this route.

So far everything is working except the following scenario:

I have a normal main.bob file that contains my 'navigation tabs' as show above .

Then I have an 'embedded' bob file named 'my_embedded'..

I have a python script :

1    from org.csstudio.display.builder.runtime.script import PVUtil, ScriptUtil
2    from org.csstudio.display.builder.model.properties import WidgetColor

3    OUT = 48
4    IN = 22
      ####################################
5    ActVal  = PVUtil.getLong(pvs[0])   #  pv actuator $(pvname)
6    StatVal = PVUtil.getLong(pvs[1])   #  pv status

      ## just building my Label_<pv_name> as pvlabel
7    prePV = str(pvs[0])
8    newPre = prePV.split(":")
9    prex = "Label_" + newPre[0]

       ########################################################
10    st = ScriptUtil.findWidgetByName(widget, "ss")          ## this widget is in my harpsgroup.bob
11    pvlabel = ScriptUtil.findWidgetByName(widget, prex)     ## this widget is in my harpsgroup.bob
12    e = ScriptUtil.findWidgetByName(widget, "my_embedded")  ## this widget is in my harpsmain.bob

if StatVal==64:
            pvlabel.setPropertyValue("background_color", WidgetColor(26, 0, 104))     #
            pvlabel.setPropertyValue("foreground_color", WidgetColor(255, 255, 255))  #
            #e.setPropertyValue("visible", True)
            st.setPropertyValue("text", str(StatVal))
            widget.setPropertyValue("y",IN)                                     #
if StatVal>64 and StatVal<128:
            pvlabel.setPropertyValue("background_color", WidgetColor(255, 0, 0))      # Red
            pvlabel.setPropertyValue("foreground_color", WidgetColor(0, 0, 0))        # Black
            widget.setPropertyValue("y",IN)  ## OUT
            #e.setPropertyValue("visible", False)
elif StatVal==128:
            widget.setPropertyValue("y",OUT)   ## IN  
            pvlabel.setPropertyValue("background_color", WidgetColor(26, 0, 104))     #
            pvlabel.setPropertyValue("foreground_color", WidgetColor(255, 255, 255))  # White
            #embed.setPropertyValue("visible", False)
elif StatVal>128:
            widget.setPropertyValue("y",OUT)   ## IN  
            pvlabel.setPropertyValue("background_color", WidgetColor(255, 0, 0)) #
            #e.setPropertyValue("visible", True)
            pvlabel.setPropertyValue("foreground_color", WidgetColor(0, 0, 0))  # Black
#########################################################

My problem comes at line 12 where it somehow cannot get to "my_embedded" widget.

In fact only widgets in 'harpsgroup.bob' is accessible .....
