Subject [jira] [Updated] (FLEX-35237) DataGridLayout is broken when used inside <js:beads/>
Date Thu, 05 Jan 2017 13:02:58 GMT

     [ https://issues.apache.org/jira/browse/FLEX-35237?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Pan Li updated FLEX-35237:
--------------------------
    Description: 
DataGridLayout doesn't work if it is added to <js:beads> of controls, but it does work
if the datagrid doesn't use any layout (thus it uses default one in css). 

To reproduce the problem:
Take the SDK's datagrid sample, change
DataGridPercentageLayout to
<js:DataGridLayout />


running the updated code in js mode, the application fails with javascript error:
{code}
