Different versions of Docapp Builder and Docapp Installer
I was recently in a situation where one developer was developing on D6 sp1 with a Docapp Installer version 6 and another was developing using 5.3 sp5 update1. The D6 developer was creating docapp archives for Forms and Process Builder which when installed using the 5.3 sp5 update1 installer left out certain form properties and functionality. It was a real waste of time trouble shooting these issues.
Creating a workflow docapp with auto activities for lifecycle promotion
If you create a workflow and have an auto activity for promoting a lifecycle state regardless of whether the lifecycle is added to the Docapp, the lifecycle will get added to the Docapp archive and installed on the target docbase.
ACLs with non dm_dbo domains
If you have set up ACLs with an owner that is not the dm_dbo (docbase user account) then these permission sets will not show up in the Docapp’s Lifecycle, Action, Add permission set drop down list.
If you are splitting the docapp work between a few developers, get ready to deal with a lot of versions of the docapp and all of the workflows, lifecycles, activities, etc.
ACL inheritance from Folder
If your docbase is set up with ACL inheritance from folders be sure to set the “System/Applications” folder ACLs. If you don’t do this, everytime you deploy a docapp its components, such as a lifecycle will inherit the ACLs of the docapp folder and may or may not work in the application.
Scoping of Display configurations
This is very strange when it happens. Let’s say you start out with a small object model of two levels and configure the display. Then you need to add a new parent level and redo the display. Sometimes the scope remains with the original model and object type. The only way I found to fix this was to dissect the database scope config and cut out the disease.
Mandatory attribute changes with old references
If you ever decide to change an object type’s attribute from required to not required, sometimes this change is held in a reference or cache somewhere. The only way I’ve been able to clear it is to delete the attribute using DAB, closing DAB, clearing the cache and inserting the attribute again.
Importance of having one source for docapp creation
I can’t stress it enough that Docapps should be created and control from one source, with the same versions of the Docapp Builder and Installer on the source and target machines. Configure the object type’s display only when the attributes and object model are final. Add workflows in with lifecycles. Try not to version docapps or its objects unless absolutely necessary. Finally, beware of the permissions that are inherited by the docapp installation.

Damned if you demo, damned if you don’t, especially if your client is new to Documentum. You can talk about functionality, show the vanilla installation of Webtop, and still get surprised looks when you show the final solution. On the flip side, you can demo the solution when it’s not fully tested and have to dance around errors and incomplete development.
Demos of a client’s project are essential if the client reads the Functional Requirements Spec and the Tech Design without too many comments. This means they don’t understand and/or don’t have enough time to review it. This can be frustrating, but if you demo the solution in front of those same future users, you’ll get invaluable feedback and will eventually have a more successful launch of the solution.
Steps to successfully demonstrate your solution:
- Test the part of the solution that will be demo’d
- Plan talking around any part of the solution that is not completed
- Have an agenda of what will be shown during the demo
- Repeat to the clients/users that this is not a finished solution, that there will be bugs
- Try to have fun with your audience, this should not be too serious
- Have other technical resources there to take notes and comment on questions that pertain to their customizations
- Listen you your client’s comments and take their feedback seriously
- Make notes of comments that could form future opportunities, like “does this mean we have to sign on to another application each time we want to access it?”. This could mean that single sign on is in the future. Or, “I already fill out this information in the database, why do I need to do this twice?” This could mean an integration possibility to ease the transition to using Documentum, not to mention make finding content easier with more integrated attributes.
- Schedule a few demos to reduce the risk of disillusionment after an error causes one demo to fall short of expectations.
- Try to impress the client each time by showing something extra in the product that they might not have seen.
- Whatever you do, do not take screenshots and dummy up the solution. This will lead to more questions and anxiety over the progress of the overall solution.
