Hi Guy,
I am Raja Krishnan from sydney and i am trying to work with the new JSP designer .I am getting this exception when i try to open the same JSP again with 2 designer windows.
I hope these JSP designer bugs will be fixed in the release version.I am using Win2000 and IE 6 with Eclipse 3.1 + MyEclipse IDE 4M3 .Exception is below from .log file.

Raja,
This restriction is by design, due to the complex synchronization issues that need to be performed between the file, the DOM model and the View we enforce only opening a single JSPs once with our new designer.

Can you explain your use case such that you need to open this in two separate editors?

[Raja krishnan]

Hi All,
If this is a Design issue then Message shown to User should convey that and not the exception…Anyway i don’t need to open the same jsp again but this can happen in eclipse ide often..
Thanks anyway for quick response.

[Riyad Kalla]

Raja I agree, I will file the issue.
