I faced this exception while trying to generate a xml document programmatically in C# using XmlDocument and XmlElement.
I didn’t know what was going on, and then I figured out that I was adding multiple elements to the XmlDocument. To solve this, add a “root” element to XmlDocument and then add multiple child elements within the root. The XmlDocument is supposed to only contain 1 child element as expected in XML.

To fix Intellisense suddenly stops working in SQL Management Studio, refresh the local cache by pressing Ctrl-Shift-R or by going to Edit -> Intellisense -> Refresh Local Cache.
Try sencha app refresh, if still doesn’t work, try sencha app build development.
Make sure that in views, for spacer, use at least a space and not an empty string. It’s an Ext Js 6.2 bug.

In Android Studio go to File -> Settings -> Build, Execution, Deployment -> Build Tools -> Gradle
Check the ‘Offline work’ under ‘Global Gradle settings’
However, if it Gradle needs to get libraries from the Internet, turn off ‘Offline work’ and run it for first time, then turn the option on to speed up build process.
Avoid using notepad to edit configuration or copy/paste things, use notepad++ where possible.
It seems that notepad sometimes can make changes to your data and make them not working.
I spent quite a lot of time experimenting to be able to do this.
Say you have a table like so
KPI Value Date
Temp 34 …
Press 12 …
And you would like to have 2 lines in the line graph, one for temperature, one for pressure, the series for pressure may use the secondary y axis. The series for pressure may use a totally different chart type(column).
To do this, don’t add KPI as a series group, add Date as a category group and add Value twice as values.
for the first Value, use IIf(Fields!KPI.Value = “Temp”, sum(Fields!Value.Value, Nothing).
for the second Value, use IIf(Fields!KPI.Value = “Temp”, sum(Fields!Value.Value, Nothing).
Configure the second value to use secondary y axis and you’re done.
