<font size="-1" face="Verdana">Hi, <br>
<br>
in a QGIS-plugin I need to read a template project file (*.qgs),
modify it to adapt it to the currently loaded database etc. using
xml.etree.ElementTree, write it and read it again. <br>
<br>
<br>
</font><font size="-1"><tt> ....<br>
<br>
qgsxml.write(projectfile) # writ</tt><tt>e</tt><tt>
modified project file</tt><tt><br>
</tt><tt><br>
</tt><tt> project = QgsProject.instance()</tt><tt><br>
</tt><tt> project.read(QFileInfo(projectfile)) # read
the new project file</tt></font><font size="-1" face="Verdana"><br>
<br>
</font><font size="-1"><tt> projectfile</tt></font><font
size="-1" face="Verdana"> contains the name of the new *.qgs
projectfile <br>
<br>
First attempt is successful, the second fails (groups are loaded
but there are no layers), third attempt is successful, fourth
fails and so on...<br>
<br>
Everything works fine when I use the menu "project > new"
before starting the plugin. <br>
<br>
Have i done something wrong?<br>
