<div dir="ltr"><div class="gmail_default" style="font-size:small">I created a map in my Print Composer window. Three weeks later, I decided to update that map. I added 3 new layers to the main QGIS window. Each layer contained a circular building, each with a different radius. The layers pointed to shapefiles named roundbldgs1, roundbldgs2, and roundbldgs3, respectively. I then combined all of those layers into one layer that pointed to only the roundbldgs3 shapefile. I then used my file manager to change the name of that shapefile to roundbldgs. I changed the name to roundbldgs for all 5 extensions used by the shapefile (.shp, .shx, .dbf, .prj and .qpj). The layer containing the 3 round buildings now points to the roundbldgs shapefile.<br></div><div class="gmail_default" style="font-size:small"><br>However, even though the 3 new buildings show up in the main QGIS window,
they do not appear in the Print Composer. I unlocked all of the items
in the map that I created in my Print Composer window (even though I didn't think that was really necessary), and then clicked
on the Refresh icon; but the map did not change. In the past, when I
updated something in the main QGIS window, I would only need to click on
Refresh to have those changes reflected in my Print Composer window. I
then tried creating a duplicate Print Composer map, and then clicking
on Refresh; but the duplicate Print Composer map did not change either</div></div>
