CSS-Boy : trigger not firing for $(pv_name) at runtime

[Amien Crombie <acrombie@tlabs.ac.za>]

Hi

I have some python code that runs fine except for one issue.

######################################################################
pv_xRange[i]      = PVUtil.getDouble(pvs[4])  # xrange

if (pv_byteStatus[i]==isIN):
     wdg[i].setPropertyValue("y",widIN)
     wdg[i].setPropertyValue("border_color",    ColorFontUtil.BLACK)
     wdp[i].setPropertyValue("background_color",ColorFontUtil.BLACK)
     wdg[i].setPropertyValue("border_width",1)
     if (hTOP.getPropertyValue("visible")==False):  ##
        hTOP.setPropertyValue("visible",     True)
        hTOP.setPropertyValue("tooltip",     str(i))
        xgT.setPropertyValue("trace_0_y_pv", pv_xtrace[i])
        xgT.setPropertyValue("title",        pv_xname[i] )
        xgT.setPropertyValue("trace_0_x_pv", sp_x[i] )        ## set the X-axis spacing i.c.w. Harp
        ygT.setPropertyValue("trace_0_y_pv", pv_ytrace[i])
        ygT.setPropertyValue("title",        pv_yname[i] )
        xrT.setPropertyValue("pv_name",      pv_xRange[i])    ### NB - here I pass the 'pv' to my Wheel-widget via $(pv_name)
        yrT.setPropertyValue("pv_name",      pv_yRange[i])
######################################################################

Now the above script code receives some pv_names from another widget-group and everything works as follows:

xgT and ygT are xy-plot widgets and xrT and yrT are Wheel widgets

As an example, my '$(pv_name)' for widget xrT is displayed correctly and I can change the pv as normal...but my python script I wrote on this widget does not fire..

somehow the '$(pv_name)' in my script windows that I pass does not fire in the script.

So I'm thinking that somehow the macro '$(pv_name)' is not updated at the time of the script execution although the CSS gui has the correct pv for '$(pv_name)' when I run CSS.

I'm using CSS-4.5 (64-bit) running on Ubuntu 18.04

Thanks

Amien
