Code Error on refreshBinding for a tag with a dataset

Ignition
1

Hi Everyone!
So, I am in the middle of a project where I am now using tags instead of queries. So long story short, I created a tag with a dataset that allows the user to update the cell value in the table, great. Now I am at the part where I am attempting to refresh the dataset in the tag binding with the new input value. My code currently looks like this:

def runAction(self, event):
	row = event.row
	col = event.column
	value = event.value
	dsTagName = '[MorningMeetings]Dash/QualityTag'
	updatedDataset = system.dataset.setValue(self.props.data, row, col, value)
	system.tag.writeBlocking(dsTagName, [updatedDataset])
	component = self.getSibling('Quality_Table)
	component.refreshBinding('[MorningMeetings]Dash/QualityTag')

However, the problem occurs on the last line. There is a red squiggle under the final ")" and I'm not sure if it is possible to update a tag like this. When I run the code, the error message doesn't compile. More specifically it looks like this:

16:06:03.776 [AWT-EventQueue-0] ERROR com.inductiveautomation.ignition.client.util.gui.ErrorUtil - Unable to run action 'component.onEditCellCommit' on White_Board/DashBoard@D/root/Three/Quality/Quality Table: code could not be compiled.

I am still looking into the problem, but any help would be great!
Thank you!

Tag bindings auto-update when something changes the tag value. No refresh required.

3

oh ok then. So I would just need to update the table, correct?

4

If the table is bound to the tag, it will auto-update.

5

My current window still does not auto update the values. For example. if I type 5 in any of the cells, my own personal screen will update but not for another session. That is the end goal.

6

Should be:

system.tag.writeBlocking([dsTagName], [updatedDataset])
7

oh wait. I was on the wrong window with a similar project name. never mind. Thank you for the help!

For future reference, your code was failing to compile because of this line:

component = self.getSibling('Quality_Table)

See how the last paren is red? You didn't close the string contained within.
