Hi all,

Unable able to open "RECENT LIST OF PROJECTS" in TIBCO Designer

When we open an empty project in TIBCO designer, you may get the below error:

In Error Stack you can see this:

 With this error you cannot create an empty project and also you can't browse the recently opened projects in TIBCO Designer startup window.

Solution: The solution for this type of error is to delete Designer preferences file and refresh. Now restart the tibco designer. The issue will be solved.

Designer preference file location: C:\Documents and Settings\<user>\.TIBCO\Designer5.prefs
