[development] check_markup() and flexinode

Hi, I'm using the 4.7 beta4 and the latest flexinode HEAD. When I try to apply the filters on the fields with this method $node->flexinode_97=check_markup($node->flexinode_97,$node->flexinode_97_format,FALSE); the filters aren't applied . In the body and teaser, everything is OK. What am I do wrong? -- Aries
