I'm wondering how I can do this little trick (sp_info is a globaly
devide var, it's a dictionary obj):
<option tal:repeat="group groups/existing/high"
tal:content="group"
tal:attributes="onmouseover string:doTooltip(event,
'${sp_info/${group}/common_name}')"
onmouseout="hideTip()">
</option>
So based on my the value of 'group' from my repeat, I want to use the
value to look up another value in a different dictionary. It works if
I do this: (event, '${sp_info/whatever/common_name}') but does not
like me using the embedded ${group}.
The ${var} syntax is only for inserting a value in a string expression.
Path expressions only take known names. If you want to look up a value
based on a variable, you must use Python. Look at the first half of this:
