That was indeed a caching issue and when I removed the cached files I no longer get the PointName error. However, I have another error which I came accross on Firefox and tested it on two sytems.
When I click on PointDetails Icon and go to the details pages I get a window with the message "Error". This error occurs only when the statistics is empty. (This does not happen for Binary points and for binary points the statitics are present.
<img border="0" onclick="getStatsChart()" class="ptr" title="Get statistics" alt="Get statistics" src="images/control_play_blue.png" id="statsChartImg" style="opacity: 0.4;"/>
HTML code for Analog points and error occurs
<img border="0" onclick="getStatsChart()" class="ptr" title="Get statistics" alt="Get statistics" src="images/control_play_blue.png" id="statsChartImg" style="opacity: 0.4;"/>
Note: The Opacity value goes into a loop for above
HTML Code for Binary points and there are no errors
<img border="0" onclick="getStatsChart()" class="ptr" title="Get statistics" alt="Get statistics" src="images/control_play_blue.png" id="statsChartImg" style="opacity: 0.999999;"/>
