False error message appears in Echoview window when adding lines

[scottclowe]

When importing an EVL file into Echoview, an error message appears in the Echoview window

However, the error message is (for the purposes of echofilter) erroneous, since the lines import correctly.

I believe the error is caused by the step

line = lines.FindByName(variable.Name)

which runs before importing the EVL file. This checks to see if a line already exists in the EV file with the name we will use for the new file.

This issue does not occur if echofilter has previously been run on the Echoview file and there is already a line with that name present.

Error reported by Louise McGarry using echofilter v1.1.0, Echoview v13.
