iReport Attribute 'uuid' is not allowed to appear in element

Some renegades still refuse to use Linux as development environment when working with Java, JasperReports, Talend etc. OSX so far looks OK but Windows one way or the other is always bringing issues.

Today I had to spend sometime with iReport Designer tool in Windows. We wanted to upgrade from version 4.1.3 to 4.7.1 so we opened the old reports perfectly in 4.7.1, compiled them, run them. Everything seemed to be perfect until the report was modified in which case version 4.7.1 would behave like version 4.1.3, basically it does not understand the new XML schema:

Error loading the report template: org.xml.sax.SAXParseException: cvc-complex-type.3.2.2: Attribute 'uuid' is not allowed to appear in element 'jasperReport'

I could not find a way to make 4.1.7 import settings from 4.1.3 without stopping from parsing correctly the JRXML which contains in newer versions the uuid attribute in multiple nodes.

So my only option was to tell the renegades to:

1. Close iReport
2. Delete the 4.1.7 settings directory. If you installed iReport in C drive here is the command to use. Otherwise locate the directory and delete it:

   rmdir /s "c:%HOMEPATH%\.ireport\4.7.1"
   

3. Start iReport canceling the import for settings from 4.1.3

Bottom line is it looks like in Windows an iReport upgrade will result in losing your previous settings.
