DRL Dumper Not Printing the content of ConditionalBranch

While trying to use conditionalbranch api for handling multiple if-then blocks, the DRL dumper is not printing the content we have used for conditionalbranch. Please find the sample code below and the restuls

Code

PackageDescr pkg = DescrFactory.newPackage()
.name( "org.drools.compiler" )
.newRule().name( "test" )
.lhs()
.pattern("Cheese").constraint( "type == \"stilton\"" ).end()
.conditionalBranch()
.condition().constraint("price < 10").end()
.consequence().name("c1").end()
.end()
.pattern("Cheese").constraint( "type == \"cheddar\"" ).end()
.conditionalBranch()
.condition().constraint("price > 10").end()
.consequence().name("c2").end()
.end()
.end()
.rhs( "// do something" )
.namedRhs( "c1", "// do something else\n" )
.end()
.getDescr();

return new DrlDumper().dump( pkg );

Output

package org.drools.compiler

rule "test"
when
Cheese( type == "stilton" )

Cheese( type == "cheddar" )

then
// do something
then[c1]
// do something else
end

In the above example the content "price < 10" and "price > 10" which we have used for conditionalBranch is not getting printed. On further investigation we found the drl.mvel template does not have the import org.drools.compiler.lang.descr.ConditionalBranchDescr.
