Compiled FV 3.1 needs reload to appear properly

RyanCoghlin

When loading my flex viewer 3.1 compiled version, it will sometimes stop loading halfway through and become unresponsive (map will load, but not all header elements/widgets in widget container appear). If I reload the page, it comes up as expected and functions normally.

When the problem occurs, content debugger reveals this:

TypeError: Error #1009: Cannot access a property or method of a null object reference.  at com.esri.viewer.components.toc.tocClasses::TocMapLayerItem/createChildren()  at com.esri.viewer.components.toc.tocClasses::TocMapLayerItem()  at com.esri.viewer.components.toc::TOC/registerMapLayer()  at MethodInfo-389()  at com.esri.viewer.components.toc.utils::MapUtil$/forEachMapLayer()  at com.esri.viewer.components.toc::TOC/registerAllMapLayers()  at com.esri.viewer.components.toc::TOC/commitProperties()  at mx.core::UIComponent/validateProperties()  at mx.managers::LayoutManager/validateProperties()  at mx.managers::LayoutManager/doPhasedInstantiation()  at mx.managers::LayoutManager/doPhasedInstantiationCallback()

Has anyone experienced this problem? Know of a solution? The fact that everything works fine after reloading confuses me. Thanks for the help!

Hi Robert,

Is there any solution for this? I am using the flex viewer 3.1 source to create the build and the problem occures only when the application is compiled and deployed.

Thanks for your help,
Sreehari

Sreehari,

The fix for this is in Beta but you can find it here because you are compiling the source code:
