I've done a bunch of experimenting to try and solve my own problem and I have been left very confused.
When I create the template for displaying the tab like this:
!{{<<currentTab>>!!title}}
<$button action="action-sendmessage" message="tm-edit-tiddler" param=<<currentTab>> tooltip="Edit this Tab">Edit Tab</$button>
I get the button at the bottom and the title of the tiddler, as expected.
When I create the template like this:
{{<<currentTab>>!!text}}
<$button action="action-sendmessage" message="tm-edit-tiddler" param=<<currentTab>> tooltip="Edit this Tab">Edit Tab</$button>
{{<<currentTab>>}}
<$button action="action-sendmessage" message="tm-edit-tiddler" param=<<currentTab>> tooltip="Edit this Tab">Edit Tab</$button>
I don't get the tiddler content, just the button.
I don't understand why the {{ }} works for some fields but not all?
