setting posrel pos

[Paul van Beukering]

Hi,   Can not find a bridge example of setting pos in a posrel relation. And so I tried:   RelationManager category2category = cloud.getRelationManager( "categories" , "categories" , "posrel" ); category2category.createRelation( superNode , node ); category2category.setIntValue( "pos" , nextPos ); category2category.commit(); but that gives me:  org.mmbase.bridge.NotFoundException: Field 'pos' does not exist in NodeManager 'typerel'. Do I need another RelationManager?   tia, Paul van Beukering
