Is there a way to add another workflow the list of workflows in the right click new menu?

Please have a look at following case:

https://support.ptc.com/appserver/cs/view/solution.jsp?n=CS185927

• To add a custom create action for Change Request soft type to folder Action > New sub menu
  • Create a subtype of Change Request

​

• Copy the action model folderbrowser_toolbar_new_submenu from <WT_HOME>/codebase/config/actions/FolderManagement-actionModels.xml to <WT_HOME>/codebase/config/actions/custom-actionModels.xml

• Add the below line to the above copied model in custom-actionModels.xml<action   name="create"  type="AgendaCR" resourceBundle="ext.custom.ActionDefinitionsRB" />   <!-- New Agenda Type Change Request -->

• In <WT_HOME>/codebase/config/actions/custom-actions.xml file added new object type for the subtype of Change Request.

<objecttype name="AgendaCR" class="wt.change2.WTChangeRequest2|com.ptc.ptcnet.AgendaCR" resourceBundle="ext.BWIR.ActionDefinitionsRB">

• Create an resource bundle file to localize the created action
• For example create ActionDefinitionsRB.java under WTHOME/src/ext/custom​

package ext.custom;
import wt.util.resource.*;
@RBUUID("ext.custom.ActionDefinitionsRB")
public final class ActionDefinitionsRB extends WTListResourceBundle {
    @RBEntry("New Agenda Change Request")
     public static final String PRIVATE_CONSTANT_1 = "AgendaCR.create.description";
    @RBEntry("NEW_ICON.gif") // <WT_HOME>/codebase/netmarkets/images
    public static final String PRIVATE_CONSTANT_2 = "AgendaCR.create.icon";
  }

• Compile using the below command:

ant -f bin/tools.xml class -Dclass.includes=ext/custom/ActionDefinitionsRB.java

• Make sure ActionDefinitionsRB.class is generated under <WT_HOME>/codebase/ext/custom
• Stop Windchill Method Server
• Clear Tomcat and Info*Engine cache
• Restart Windchill Method Server
• The new action should now be under to Action -> New menu as below

• Note: the image size must be smaller than 16*16 pixel and it should be placed inside <WT_HOME>/codebase/netmarkets/images directory.
• Disclaimer : PTC recommends following best customization practices to avoid maintenance installation process overwrite. Please go through “5. Managing Customizations” chapter in Windchill Customization Guide.
