RE: [flexcoders] Using a logical AND in property.
Perfect Gordon thanks. Never thought of that. I understand the reasoning
behind this. Even though it's not easy to read, an interaction designer can
learn this faster then vars and functions etc... for basic interaction
logic.

RE: [flexcoders] Using a logical AND in property.
Thanks for your help, but I was looking for something closer to what Gordon
posted.
i.e. amp;amp; instead of Im trying to keep interaction designers from
writing to much action script code for basic interaction logic.
Thanks again.

Jason,
I know this doesn't actually answer your question, but I ran into the same
thing recently and found that I was looking at the problem backward. I was
trying to set enabled on a Panel based on whether one or more rows were
selected in a DataGrid. I tried the same things you did, adding AS code to
the Panel's enabled property. I had all kinds of trouble and nothing seemed
to work right, until I decided to do things backwards.
Instead of adding code to the enabled property that watched or was bound
to other values or components, I added an itemClick=panelEnabler(); to the
DataGrid. The panelEnabler() function just looks like:
public function assignPanelEnabler():void {
if(dgAccts.selectedItems.length = 1)
{ assign_panel.enabled=true; }
else
{assign_panel.enabled=false; }
}
Now, the DataGrid runs the function whenever items are clicked, and the
function changes the enabled property for the Panel. Works perfectly, and
you don't need to worry about using inside the enabled property field,
you can put all your if...then logical operators in the function script.

RE: [flexcoders] Using a logical AND in property.
I get the same error. The entity name must immediately follow the '' in
the entity reference.
This should be simple, and for designers way less complicated then writing a
function, or dealing with bindable vars etc
to do the same kind of stuff.
I totally put this in the interaction designer domain space.
Thanks for your help.
