[flexcoders] Re: RTE when setting spark gridcolumn visible property (f
Yes agreed. In our newer applications we do that.
Just curious, if a column is defined as visible=false in mxml. That wouldn't be
a memory consumption would it?

Halo datagrid doesnt have this problem.
In our scenario, some columns have no relevance to certain customers.
Instead of removing the column from the mxml, we store the column info (in
this case make invisible) in the database.
During the datagrid initialze we make it invisible. The creationcomplete
event would be too late because by then the column would have rendered (for
a split second).
Preinitialize would be ok...but other parts of my code (unrelated to this

[flexcoders] Re: using a coldfusion proxy to show twitter feed in flex app
Sorry, I am out of my depth here. I don't use ColdFusion.
All I can suggest is creating a debug file on the server and dump to the file
to see if you are getting the desired response. After that, use Charles to see
if the server is sending the correct response.

You will need flex-iframe from
https://github.com/flex-users/flex-iframe/ to embed the HTML.
Note that this is a quick and dirty example with no error checking etc.
You should use this to further your understanding rather than as a basis
for production code.
