#6133-FI: Gantt diagram inside flex 4 container generates errors

[StanislavZ]

When chart located inside mx:Box container everything works fine, however if we remove mx:Box it doesn't.

Hello,

Any details about the errors you obtain?
Do you work on flex 4 or on flex 3?

Luiza,

As you see from attached project, I'm working on Flex 4, when you run the application you will see 2 charts, one is populated with data and another is not.

Thanks,

[Luiza]

Hello,

I'll investigate this problem.
From backward experience, when working with flex 4, it is better to place your gantt in a flex 3 container (Box, Panel etc).
Also printing will generate errors if you don't do that.

Luiza,

Thanks for answer! I gues this is a bug?

Do the team plan to fix it?

[Luiza]

Yes,

But this is not a high priority issue.

Hello,

I am currently working on fixing this bug but I can't reproduce your problem because the link that you have given us (http://dl.dropbox.com/u/16113866/gantt_test.fxp) is not active anymore. Can you please give us another location for your project ?

Thank you in advance and I will wait for your answer,
Dana.

Hi there.

We are experiencing the same problem. Our app used TabNavigators so the gantt chart is in a tab. I tried wrapping the gantt in an mx:Box as suggested above but am getting an error.

Help would be very appreciated here as we intend to release soon!

Code from MXML...

<s:NavigatorContent   xmlns:local="*" ... removed for ease of post>

<s:VGroup width="100%" height="100%">   
      <s:HGroup width="100%" height="100%">

Hi Luiza

That is good news, I saw on another post that Cristian gave a prerelease to someone, is that possible? / When is the next release? To fix this issue, I've temporarily switched the WindowedApplication to mx, but that plays havoc with our application in terms of styling.

All the best
