Thread application error on file upload

Hi,

In EWB 1 I have a fileupload which works fine, but since today I get an "application error acces denied" after I have selected the file. I have changed nothing in the source (except recompile).

I know there is a security issue here: you get this error when you try to write to the TPage component which is used as the FormOutput page, but I do not do write to the TPage.

Has anyone come accross this and found a solution?

Greetings,
Ronald

I was browsing through the source in the EWB framework and found a realation with HTML5 in the TFileUploadButton. That reminded me that I recently had switched on the HTML5 support for my application. When I turned this off all worked fine again.
Why do I get this error in HTML5?

The HTML5 checks in the TFileUploadButton (EWB 1.x, for readers), are for client-side IE issues with how the underlying browser element is used.

Are you getting the error when you select the file, or when you submit the form ?

Hi Tim,

I get the error directly after selecting the file.

I have found that the FileSelector in Windows when it has a file preview sometime HOLDS the file and you get the File In Use error.

Hi Walter,

I tested your suggestion, but unfortunately that did not solve the problem.
