Mystery solved.
I found the culprit: my use of a "part" attribute on the div that contained
the tag trying to reference the attribute of the enclosing tag. And, not
having included this little detail in my original posting, that suggests
why, Ignacio, you were not able to reproduce the same issue.
So, in my full example, I should have shown my use of the part attribute:
<def tag="plans" attrs="showspecialcontrols">
<div part="special_plans"
<my-table-plus:plans fields="plan_no, plan_type" showmycontrols="
&showspecialcontrols">
...
</div
</def>
Including the "part" attribute shifted the context for my subsequent tag
my-table-plus.
Since I've just hit this very same problem with another example, I would
really love to know *why the "part" attribute shifts context*. And, how is
specifying "part" any different than simply tagging the <div> with an ID
and using the updates="#div1,#div2" syntax. *Is "part" now an antiquated
way of doing things?*
