Using the PowerChart, I am able to hard-code the tagBrowserStartPath property and have the Tag Browser populate with the appropriate results. However, when this property is built from an expression, script, or really any other way than hard-coding, the Tag Browser will only display the appropriate results after a manual refresh (clicking the control refresh button). Here is the format I’m using for the tagBrowserStartPath: histprov:[history provider]:/drv:[system name]:[tag provider]. This seems to be correct, and works fine - as long as it’s hard-coded. Am I missing something?
