Does the <ObjectName> refer to a variable which contains the name of the object? Or should I replace it manually with a suitable name?
The IDE generated #XTIT: Table view title worklistTableTitle=<ObjectName> in i18n.
When you use SAP WebIDE to create a template/application, it may create i18n files with placeholders for you to replace them with your own application specific texts. In your case, in the code below <ObjectName> represents a placeholder for your own text.
#XTIT: Table view title
worklistTableTitle=<ObjectName>
It does not refer to any variable, you simple have to add you own text in that field. Something similar to this :
#XTIT: Table view title
worklistTableTitle=My Products List
