Hey Kevin:
Good idea, but that just produces:
undefined method `showspecialcontrols' for nil:NilClass
Hey Ignacio:
How odd that you can't reproduce it. I'm currently using Hobo 2.0.1 - is
there anything in a later version that would have altered this behaviour?
So, evidently when calling my-table-plus:plans there is no "parent" (which
I guess makes sense).
Deeper in my own definition of my-table-plus, I pass an attribute on as a
value to another custom tag with no problem (as do many other Hobo tags). This
difference here, is that the call to <my-table> doesn't shift the context.
<def tag="my-table-plus" attrs="sort-field, sort-direction, sort-columns,
showspecialcontrols" >
...
<my-table showspecialcontrols="&showspecialcontrols" ....>
<field-heading-row:>
But, I'm curious why you can't replicate the behaviour....!
