Hi2All:
I met a strange problem when used FileUpload widget.I have created a
ViewPart, added some codes in createParentCOntrol method.In ViewPart,the
parent compsite(not scrolledComposite) only includes fileUpload widget
which has no listener be implemented.It works fine when the viewpart has no
scrolledComposite. in order to add more than one fileupload widget, I have
to use scrolledCompoiste,so I add fileUpload widget in it. also it works
fine when i started the Rap. but After I closed the ViewPart, then open it
again,it shows "Could not evaluate javascript response:" on web page. there
are only a scrolledComposite difference in createParentControl method. is
my code with problem? or FileUpload widget has problem. I am confusing.
my codes as Attachment
UploadViewTest1.java has problems.
UploadViewTest2.java works fine.
reproduce step:
1.open UploadViewTest1
2.close UploadViewTest1
3.open UploadviewTest1 again ("It will show Could not evaluate javascript
response")
can anyone tell me what's wrong with it ?
thanks in adavance

Hi,
which code base do you use? Not long ago, client side widget pooling was
enabled for the ScrolledComposite which caused stranged JS-errors.
Please check, if the method ScrolledCompositeLCA#getTypePoolId returns
NULL. If not you may want to change this temporarily and see if the
problem persists.
Regards,
Stefan.
