Enabling Discussions in PTC FlexPLM
To enable the Discussions feature in PTC FlexPLM, set the following properties on your Windchill server:
1. Add the following entry to custom.lcs.properties:
jsp.discussionforum.discussionforum.enabled=true
2. To configure the following properties, add them to wt.properties.xconf, and then run xconfmanager -p:
To control posting delete operations, set the following property:
wt.workflow.forum.posting.delete.ownerOnly=true
To control the topic delete and close operations, set the following properties:
wt.workflow.forum.topic.close.ownerOnly=true
wt.workflow.forum.topic.delete.ownerOnly=true
To control topic creation, set the following property:
wt.workflow.forum.CreateDefaultTopics.enabled
This property controls the creation of default topics. This property must be added to the wt.properties file. By default this property is set to true, which means that when an object discussion tab is visited, default topics are created as defined in the DiscussionForumTemplate. If this property is set to false, the forum does not have any default topics created in it.
To control tree view and posting replies, set the following property:
wt.workflow.forum.TreeViewAndReplyPosting.enabled
By default, this property is set to false. To allow tree view and replies to posted comments, set the property to true.
