Hi connect2vishal,
I don’t know whether we can do this in UML1 or not, I’ll escalate the issue to the dev team, but you can try this in UML2.
The steps are given below to create a Sample Class and define a property in interface.
1) Create a Web project
2) Create a UML2 model
3) Select MyEclipse UML perspective
4) In the uml model, you’ll have a left panel with Objects, Connections and Comments
5) Now, Select “Interfcae” from the “Objects” section, drag and drop into the model area.
6) Right click on the Interface and select “Add Property”
Thanks,
Chakri.
