I have a mouse over event that collects all the system history tags and fills a drop down with the found history tag names. I used the example in the docs for this. It works well, however, if I add historical tags, these new tags do not show up in the tag list until the gateway is restarted.  
These new tags appear in the history database if I do a query with the Database Query Browser tool.

Is there any way to refresh the available history tags without restarting the gateway?

Copy of script below:  
devices = [self.getSibling(“RadioGroup\_PLC”).props.value]  
tList = []  
labels = []  
outPut = []  
for device in devices:  
path=‘histprov:Historian:/drv:Ignition-nri-gw:default:/tag:’+device  
browse = system.tag.browseHistoricalTags(path) #We call the function and place the BrowseResults  
#that get returned into a variable called browse.  
results = browse.getResults() #We can then call getResults() on the BrowseResults variable, and store that in a variable called results.  
for result in results: #We can now loop through the results in a for loop.

```
	theTag = result.getPath() #We then call .getPath() on the individual objects to get the Tag Path.
	#create list of tags
	tList.append(theTag)

#split off just the tag name for the label
for i in tList:
	justTag = str(i).split("tag:")
	labels.append(justTag[1])
	
#populate the selector with tags
#theTag is the entire path
#labels is the label
headers = ['value','label']
outPut = zip(tList,labels)
outPut.sort()	
	
options2 = system.dataset.toDataSet(headers, outPut)
sortedOptions = system.dataset.sort(options2,"value")

#load the list into the TagSelector
self.getSibling("TagSelect").props.options= sortedOptions
```

I’m running into the same problem. Gateway restart was required to update the list. Were you able to find a refresh function?

No, I haven’t found a solution.
