I am finding that in case of multiple controls (ControlWrapper) being
bound to a single chart (ChartWrapper) for a dashboard, the
getTableRowIndex does not return the correct row number from the
original DataTable when used to get the row number of selected row
(getSelection).
If there is only a single control, then it works fine, however if
there are multiple controls, either specified together (using an
array) or separately (by chaining bind function) then the row index
returns incorrectly for the 1st control.
e.g. based on the Google Playground example
______________________
Ex1.) the ChartWrapper - barChart is bound to only 1 control -
cityPicker
new
google.visualization.Dashboard(document.getElementById('dashboard')).
bind(countryPicker, regionPicker).
bind(regionPicker, cityPicker).
bind(cityPicker, barChart).
draw(data);
}
If a value is selected in countryPicker or regionPicker then the row
index returned on selected a raw is as per the 'visible' row index and
NOT the original row index in the DataTable.
If a value is selected in cityPicker then it selecting a row returns
the correct row index.
______________________
Ex2.) the ChartWrapper - barChart is bound to multiple controls
new
google.visualization.Dashboard(document.getElementById('dashboard')).
bind([countryPicker, regionPicker, cityPicker], barChart).
draw(data);
}
If a value is selected in countryPicker then getTableRowIndex returns
INCORRECT row index.
However, if regionPicker or cityPicker are used, then it returns
correct row index.
______________________
Ex3.) the ChartWrapper - barChart is bound to multiple controls and
order is changed
new
google.visualization.Dashboard(document.getElementById('dashboard')).
bind([regionPicker, countryPicker, cityPicker], barChart).
draw(data);
}
If a value is selected in regionPicker then getTableRowIndex returns
INCORRECT row index.
However, if countryPicker or cityPicker are used, then it returns
correct row index.
Any ideas or suggestions are welcome..
