Hi All,

I am trying to create a document using groovy script. Below is the code. when i tried executing the script, it throws constraint violation exception. Could you please suggest me what went wrong ?

**Error details:**  
Failed to save session - javax.jcr.nodetype.ConstraintViolationException: /content/documents/riversource/experience-pages/onecolumn/xpage/xpage[2]: mandatory property {[http://www.onehippo.org/jcr/hippostdpubwf/nt/1.0](http://www.onehippo.org/jcr/hippostdpubwf/nt/1.0)}lastModificationDate does not exist

**Groovy Script**  
package org.hippoecm.frontend.plugins.cms.admin.updater

import org.onehippo.repository.update.BaseNodeUpdateVisitor  
import javax.jcr.Node  
import javax.jcr.RepositoryException  
import javax.jcr.Session

class UpdaterTemplate extends BaseNodeUpdateVisitor {

boolean logSkippedNodePaths() {  
return false // don’t log skipped node paths  
}

boolean skipCheckoutNodes() {  
return false // return true for readonly visitors and/or updates unrelated to versioned content  
}

Node firstNode(final Session session) throws RepositoryException {  
return null // implement when using custom node selection/navigation  
}

Node nextNode() throws RepositoryException {  
return null // implement when using custom node selection/navigation  
}

boolean doUpdate(Node node) {

```
log.debug "Updating node ${node.path}"   

Node draft = node.addNode("xpage","riversource:SimpleDocument")

```

if(hasMixin(draft, “hippostd:publishableSummary”)) {  
log.debug “hippostd:publishableSummary Already added”

}

}

boolean hasMixin(Node node, String type) throws RepositoryException {

```
if (!node.hasProperty("jcr:mixinTypes")) {
  return false;
}
 NodeTypeManager ntMgr = node.getSession().getWorkspace().getNodeTypeManager();

for (Value value : node.getProperty("jcr:mixinTypes").getValues()) {
NodeType nt = ntMgr.getNodeType(value.getString());
if (nt.isNodeType(type)) {
  return true;
}
}
return false;
}

```

I don’t think this will work, it should be a Calendar type and not a string…
