Design mode error

Hi,
I'm creating a Flex application in which I use several
extended components I created in a separate lib.
In my root application, only for some of the extended
components, I get the following warning:
"Design mode: Error creating item com.foo.bar in parent
Application. Please choose Design > Refresh to refresh design
mode."
The refresh doesn't work, and those components don't appear
in the design mode.
I couldn't find the cause for some of the components to
behave differently.
All the components work as expected when running the app -
the problem is only in the design mode.
Did someone encounter this problem and know how to resolve
it?
Thanks,
Y.

It is related to the non-visual components. Sorry I didn't
see this thread earlier.
There is a flag you can use in your code to prevent
instantiating these pieces when you are in design view.
First, import the internal name space and UIComponentGlobals
import mx.core.mx_internal;
import mx.core.UIComponentGlobals;
Inside of your source, you can do the following:
if ( UIComponentGlobals.mx_internal::designTime ) {
//Things to do in design view
} else {
//things to do at runtime
I prevent any validators or rpc services from instantiating
in design view. This has made a world of difference.

Design mode: Error during component layout. Choose Design Refresh to refresh design mode.

Description Resource Path Location Type
Design mode: Error during component layout. Choose Design > Refresh to refresh design mode. etPlayer.mxml /etPlayer/src Unknown Problem
Refreshing wont work..
any ideas?

Some elements can cause the design view to break, it recently happened to me and this was my solution.
I began by commenting out most of the visual elements from code and going back and forth to design view to try and get it working.
Finally I narrowed it down to the "ToggleButtonBar" component. After I commented this line out the design view was up and running.
This might not be the solution but it will get you back up and running.

Designer mode error.. VS2013

Hi,
Something has changed in my PC. I can drag and drop NI controls into forms but those are not visible anymore when the form is reopened. Please see the following picture:
I can compile the software and everything works OK in the compiled program.. Just the designer mode has the problem..
I have VS2013 and MS3013. The environment has been configured to work together and it has been OK one year or something. Maybe something happened when I tried to update Measurement Sudio.. there were some new option for VS2013 but I never could install that.

Solved!
Go to Solution.

Hi, Ilkka
This issue is being caused because the Visual Studio designer is loading NationalInstruments.Common from the program files directory instead of from the GAC. This seems to be happening because the Visual Studio designer is loading assemblies in a way that ignores configuration files.
The solution is to copy the latest version of Common and its dependencies to the program files directory where all the current Measurement Studio assemblies are. To fix the issue:
Copy NationalInstruments.Common.dll from C:\Windows\Microsoft.NET\assembly\GAC_MSIL\NationalInstruments.Common\<latest version>\ to C:\Program Files (x86)\National Instruments\MeasurementStudio<version>\DotNET\Assemblies\Current.
Copy NationalInstruments.NiLmClientDLL.dll fromC:\Windows\Microsoft.NET\assembly\GAC_MSIL\NationalInstruments.NiLmClientDLL\<latest version>\ to C:\Program Files (x86)\National Instruments\MeasurementStudio<version>\DotNET\Assemblies\Current.
Copy NationalInstruments.MStudioCLM.dll from C:\Windows\Microsoft.NET\assembly\GAC_MSIL\NationalInstruments.MStudioCLM\<latest version>\ to C:\Program Files (x86)\National Instruments\MeasurementStudio<version>\DotNET\Assemblies\Current.
I use a few placeholders in the steps. <version> is the version of Visual Studio support you have installed (e.g., VS2012). <latest version> is the latest version of the assembly which exists in the GAC folder (e.g., v4.0_15.0.40.32769__dc6ad606294fc298).
This issue does not appear to happen in Visual Studio 2010 and earlier. At this point, it seems like a bug in the Visual Studio 2012 and later design view. I will update this page when we uncover more in our investigation.
Would you mind posting a picture of the contents of C:\Windows\Microsoft.NET\assembly\GAC_MSIL\NationalInstruments.Common\ here?

Design mode troubles - "Error during component layout."

Hi all.
Since this is getting pretty annoying, I thought someone might know the right solution to this. Whenever I try to open Design mode on my AIR app (Spark + MX), I get:
Design mode: Error during component layout. Choose Design > Refresh to refresh design mode.    MyTestApp.mxml    /MyTestApp/src    Unknown    Problem
The MXML code for it is as simple as it can get:
<?xml version="1.0" encoding="utf-8"?>
<s:WindowedApplication xmlns:fx="http://ns.adobe.com/mxml/2009"
                            xmlns:s="library://ns.adobe.com/flex/spark"
                            xmlns:mx="library://ns.adobe.com/flex/mx"
                            skinClass="spark.skins.spark.SparkChromeWindowedApplicationSkin"
                            >
</s:WindowedApplication>
And app descriptor XML only contains transparent set to true and systemChrome to none, even tho it shouldn't make any difference in the Design view anyway. Refresh doesn't solve the error, and sometimes the Design view itself goes into infinite loop of refreshing.
However, if I remove the skinClass, it all works fine and Design view loads (but then I don't get the window chrome on run-time). Same goes if I declare the skin within <fx:Style /> tag, it only breaks when using skinClass attribute in the WindowedApplication declaration. And the same thing happens if I try to edit some of the Spark skins in the Design view.
I've tried creating a new project, switching workspaces, building a blank workspace, switching from Flex SDK 4.1 to 4.0 - all to no avail, the same error always occurs and it never goes away.
Any ideas?

Instead of declaring the skin within the WindowedApplication tag, you have to call the Skin class from a Style tag right after you close your window tag:
<?xml version="1.0" encoding="utf-8"?>
<s:WindowedApplication xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark"
Xmlns:mx="library://ns.adobe.com/flex/mx"
title="YOUR APP">
<fx:Style>
@namespace s "library://ns.adobe.com/flex/spark";
s|WindowedApplication
skinClass:ClassReference("spark.skins.spark.SparkChromeWindowedApplicationSkin");
background-color:#999999;
background-alpha:"0.7";
</fx:Style>

Report opens in "Design" mode and throws error

Hi All,
One of my user gets an attached error when he opens a report. I noticed that, this happens because his report always open in "Design" mode. Now when we click on "Reading" mode, it works fine.
Also, this behavior is happening only for one report. What can be the issue ? Is there a way in settings that I can do, so that the report always opens in "Reading" mode.

Check this KB:
2016483 - error: "while trying to
invoke the method java.util.List.iterator() of null object loaded from
local variable 'nodes' (Error: INF)”

Compiling code throws undeclared errors when trying to view form in design mode.

Let me start this off by admitting that I've committed sacrilege - I edited code inside of a windows forms InitializeComponent() function. I changed this (located in the beginning of the InitializeComponent() function where all UI elements are declared):
this->image = gcnew OpenTK::GLControl();
To this:
OpenTK::Graphics::GraphicsMode^ temp = gcnew OpenTK::Graphics::GraphicsMode(ColorFormat(16, 16, 16, 16), 16, 0, 0, ColorFormat(16, 16, 16, 16), 3 , false);
this->image = gcnew OpenTK::GLControl(temp)
The result is that the code still compiles, but it gives the following errors when I try to view the code in design mode:
The variable 'image' is either undeclared or was never assigned.
"The variable 'temp' is either undeclared or was never assigned."
The former can get eliminated by using two constructors, one with no parameters, followed by an immediate override of the image object with my actual constructor. But I can't seem to get rid of the second problem. Declaring the variable temp outside of the
function didn't help, so I'm not sure if or how I can make this work. Any suggestions on how I can make the design mode parser accept my intrusions? I understand that I've done some evil things to make this happen, but I'd like to keep it more or less like
this since the result is that I have a vsynced windows form.

Hi MHoll4,
It seems that it is not the correct forum for this issue.
Since this issue is related to the WinForms app, I suggest you post this issue to the WinForm forums here:

Gui error: Unable to initialize New Visual Design Mode

SAP Frontend Server
Unable to initialize New Visual Design Mode.
Please use Classic Mode.
What can i do with this error? Thanks

Hi,
Do you see this error only in 1 system. If yes, perform the following:
1. Install the updated display drivers.
2. Check the operating system (some old operating systems such as Windows 98, NT doesn't support Visual designs.)
3. Check that you have the latest version of SAP GUI patches installed.
If the problem persists, run sapsweep.exe and install the GUI again.

SWC Load Error - Design Mode Problem

Hi,
I'm loading custom .swcs into my Flash Builder (4.5 Burrito) project and I get these errors. These will only appear in design mode (not in source mode) and will not be labelled under the Problems tab, rather the Design Mode Problems tab:
SWC Load Error
SWC file failed to load. Any component dependent on this SWC file will not be displayed in the Design Mode.
The SWC may have failed to load because of:
* Incompatible definitions caused by usage of a different SDK version
* Missing referred class definitions
I don't think this problem is caused by an SDK incompatibility, as all these swcs have been created under flex 4 and I'm pretty sure under the 4.5 SDK.
Loading the components contained in these swcs onto my canvas (at design time) will work fine. I'm able to build and run the application without any errors caught by flash builder.
Any idea how to fix this problem, or what it means?

SWC Load error indicates that the swc used does not match with the definitions present in design view or with what is present in already loaded other lirbaries. The issue is reported by the flash loader. It looks like that, your swc is compiled with a previous version of the sdk and the design view and the related definition correpsonds to another version.
The incompatability logic is not in DV. When DV tries to load all the swc details available in the project, the loading fails as the loader reports the issue. There is hardly anything, we can do here from DV. If the player reports the incompatability issue, the loader is corrupted and all further loading is ignored. So to avoid such issue, DV ignores the failed swc's and tries to proceed.
If you pass me the swc , I can give the details of the incompatability. Ideally between 4.5 and 4.5.1 there should not have been any incompatability. However your case shows there is. You can contact me at [email protected]

mx:Image no image preview in Design Mode

Inside my Flash Builder (4.01) AIR project, the image preview in design mode for the mx:Image component does not show the image set with the source attribute.
This seems to be a project specific problem. When I create a new project , insert mx:image and set the source to an image, the image is previewed just fine. I also get a possible related error saying : "Design mode could not load swiz-framework-1.0.0-RC1.swc. It may be incompatible with this SDK, or invalid. (DesignAssetLoader.CompleteTimeout)"
This error pops up in several google searches and is by some regarded as an sdk bug, so I dont know the relevance here.
This happens in various flavours of the Flex SDK (4.0/4.1 latest versions).
Thanks in advance

Ok, I found out it has definitively something to do with the "Design mode could not load swiz-framework-1.0.0-RC1.swc. It may be incompatible with this SDK, or invalid. (DesignAssetLoader.CompleteTimeout)" warning. This somehow affects the loading of the mx:Image.
Recompiling the SWC might work with the swiz swc, but there are more swc's giving this error like the google maps swc which does not have the source avalable freely.
This is a real pain as I like to use a mockup image in Design Mode to place components exactly as provided by the design team.

Unable to open jsp file in Design mode

Hi,
I am unable to open jsp files in design mode, I am using eclipse Version: 3.6.1.
Please help.
Regards,
Ale Hasan

Hi Ale,
Thank you for the additional information. Unfortunately, there does not seem to be anything unusual about your project based on your description. I'm surprised you don't see any processes listed in the process view while waiting for the page to open. I thought you might see something related to a queue manager job to "Manage Resource Event Jobs".
Are there any messages in the error.log? You can open a view to the error log from the menu option, "Window -> Show View -> Error Log". I'm curious if there are any messages about a process timing out, unable to reset some object within a certain time, or any exceptions logged.
If you change to another workspace with just a single JSF web project containing a smaller number of JSP, do you experience the same behavior?
Can you also try using a more recent release of OEPE to see if that helps? The 11.1.1.6.1 release is about a year old.

Pie Charts causing Design mode to give warning and not preview the app

I am using the final release. I have pie charts in my app. I
also have column charts. Both are fed data the same way. Both work
as expected when i build the app, and there are zero errors in the
app. however, i was experiencing an issue in flexbuilder where in
design mode, a vague warning was issued and the preview could not
be displayed (blank except for very gernal 'outlines' of the layout
and controls)
I narrowed the problem down to the pie charts. Is anybody
experiencing this problem? The application worked as expected, and
previewed as expected in Design mode when previewd/built in Beta
3.

Hi masavran,
For this issue, it's related to the render environment (browser/application). On Reporting Services side, we don't have any properties to change the resolution for chart to make it smoothly. We suggest you post this thread on Visual Studio forum
http://social.msdn.microsoft.com/Forums/vstudio/en-US/home?forum=visualstudiogeneral&filter=alltypes&sort=lastpostdesc
Or the forum of corresponding browser.

How to edit text in design mode - i.e get an I cursor instead of arrow

DW CS6 This is a very basic unclear on concept question. I normally work in code view and have no problems. Sometimes there is a large block of text within a paragraph which is in a div.
I would like to correct a simple typo or insert some more text directly from the design mode display. However, almost all the time, when I click on the spot I want to modify, the cursor remains an arrow and the entire div gets a yellow border. I still have the select arrow, not the vertical bar I need to edit.
Sometimes I seem to stumble onto the right set of clicks and get the edit bar.
Thanks for any suggestions.

Design View can get pretty cranky when your code has errors.
Check the validator at http://validator.w3.org and make sure you're working with clean code before resorting to wiping preferences, config folders or reinstalling.
If your code is clean and it's still not allowing you to click your text in Design View, you may have a z-indexing issue. I notice on pages that use a lot of positioning (APDivs) you can accidentally cover up your text boxes with blank/transparent areas of other elements and cause problems when trying to access that text at a later date.
It's all guesswork though without seeing your actual page.
Could you post a link?

Design Mode Preloading alert when upgrading from SDK 3.6 to 4.5.1

I am getting an alert in Flash Builder while I am in the process of upgrading my application from 3.6 to 4.5.1. The alert is titled "Design Mode Preloading" and includes the following text:
"Preparing the design mode for this MXML is taking longer than usual, likely due to the complexity of the layout..." Then I am asked whether I want to continue the preloading.
I did not get this alert in the same Flash Builder instance when building my application with SDK 3.6. As such, I am uncertain if this issue is a product of Flash Builder or the SDK.
Has anyone faced this same issue? If so, were you able to resolve it, and how?
Thanks as always!
Lee
**Origininally posted in FlashBuilder AForum**

I continue to get this error. Could an employee please comment?
My application is data-centric and contains over 100 DataGrids. I do not know if this matters. In Flex 3.6 this error does not occur. Only once the app is converted to 4.5.1.
Thanks,
Lee

Design mode could not load ... It may be incompatible...:FB4 Beta 2 and Flex SDK 4.1

Hello,
ever since I upgraded to the latest nightly builds about two weeks ago (SDK 4.1) I get the error mentioned above, and the design mode of Flash Builder 4 Beta 2 doesn't work any more:
Design mode could not load he.enwipe.core.swc. It may be incompatible with this SDK, or invalid. (DesignAssetLoader.CompleteTimeout)
Design mode could not load PureMVC_AS3_MultiCore_1_0_5.swc. It may be incompatible with this SDK, or invalid. (DesignAssetLoader.CompleteTimeout)
and also all other "swc" inside my project that do not come directly from the SDK or Flash Builder.
Any ideas what could be the cause?

Hi,
Did you switch your projects build option to merge into code rather than have runtime libraries generated.
David.
[edit'] I really should sleep a bit more- I miss read the question, but you will probably need to break down your project to see what the issue is mxml by mxml, one thing is that any mxml headers need to halo name space renamed to mx.

sss999sss, Dezoris, ypeng, GJam564: Can you guys reproduce the issue still?
When you can, please comment on this bug http://bugs.adobe.com/jira/browse/FB-25594 and attach your error log from your workspace
Win: C:\users\you\Adobe Flash Builder 4 Plug-in\.metadata\.log
Mac: /Users/you/Documents/Adobe Flash Builder 4 Plug-in/.metadata/.log
It would be helpful to know if this is limited to a particular MXML file or if it also reproduces in an empty Application.
Also, just to be sure, try to reproduce this bug a new workspace:
1) File > Switch Workspace > Other...
2) Specify a new folder
We'll continue to follow up on FB-25594. Again, please post your log and platform (mac/win, memory, etc.) information on the bug.
