Re: [flexcoders] **View States Problem**
Continuing Chet's line of thinking - You might want to create a state
hierarchy so that state1 is based in the base state, and state2 is based on
state1, and in each one refine the view elements per your requirements.

Hi,
I am using Flex 3
I am trying to use view states in my Flex application. My code seems
to work fine when I just have two view states, but when I have 3
states (including the base state), the screen never displays all 3 at
the same time. I am displaying these states based on the result of a
remote call, that part works fine so the remoting part of it is not
the problem.
In Flexbuilder 3 if I go into design view, I can traverse through the
states (base, state2, state3), and the visual displays look correct.
Anyone have any idea or thoughts?
Here is my code below:
mx:states
mx:State name=state2
mx:AddChild relativeTo={frm} position=lastChild
mx:FormItem label=Select Sub Area:
mx:ComboBox
id=cb2
dataProvider={subAreaAC}
labelField=state2
width=216 left=10 top=40 minWidth=150 /
/mx:FormItem
/mx:AddChild
/mx:State
mx:State name=state3 basedOn=state2
mx:AddChild relativeTo={frm} position=lastChild
mx:FormItem label=Select Sub-Sub Area:
mx:ComboBox
id=cb3
dataProvider={subSubAreaAC}
labelField=state3
minWidth=150 /
/mx:FormItem
/mx:AddChild
/mx:State
/mx:states
!-- this is basically my base state, this gets showed by default --
mx:Form id=frm x=10 y=10
mx:FormItem label=Select a Parent Category:
mx:ComboBox id=cb1
labelField=ParentCategory
width=150 left=10 top=40
dataProvider={catAC}
rowCount={catAC.length / 2}
/
/mx:FormItem
/mx:Form
Re: [flexcoders] **View States Problem**
I think it's just a case of the OPs terminology - he expects to see components
from the base state plus state2 when he switches to state3. I don't think he
means being in three states at the same time..

Hi Malik,
I have amended your code to make it runnable as an example (something you
should have done).
Basically I have added three buttons to the base state to switch state,
plus made some stub data providers.
Everything works as expected (in terms of view states anyway), so I don't
think your problem is related to view states.
