shouldnt this:
<cf_data_list query="myQuery">
<cf_column
headerText="Name"><cfoutput>#myQuery.name#</cfoutput></cf_column>
<cf_column
headerText="Date"><cfoutput>#myQuery.date#</cfoutput></cf_column>
</cf_data_list>
be this:
<cf_data_list query="myQuery">
<cf_column
headerText="Name" columnName="name"></cf_column>
<cf_column
headerText="Date" columnName="date"></cf_column>
</cf_data_list>
and therefore all the need for iteration/notation knowledge is taken away
from the user?

modify the request stream)
Yes I know the solutions, and they are easy. However they could be easier.
If I want to develop a custom tag to iterate a query object I should *first
think the code* instead of just typing. What should I think:
- First think a solution for iteration
- Hmm, users of my custom tag have to use array notation
- I need to document this: "don't use myQuery.myField notation, use array
notation"
- I should provide a variable to use with array notation: <cf_data_list
query="" rowVariable="" />
- And I and users shouldn't forget thread issues in CFCs, users should
remember to define their function local row variable while using this custom
tag in functions.
Maybe this is a little boring and unimportant topic, but all of them for
more easier solutions.
Murat.
