Here is the link you can see the problem.
I have posted this problem this morning but the answers were not fit for my issue. I created a complex layout, and in the content area, I just copy the example code of layout dialog. When I click the "Show Dialog" button, the dialog pops up, but it is under the grey mat.
Then, I changed "modal:false" to "modal:true", the dialog box is still under the shadow.
I have no idea!
Please help. :cry: :cry:
