Dear experts,
I'm facing an issue in downloading a file using the <af:fileDownloadActionListener/>. I intend to have a simple content management system. I have the following project setup:
- Two database tables, FOLDERS and FILES.
- In my ADF application, I created the corresponing business components.
- I have setup my taskflow such that I can get the folder directory, and the files contained.
- Note that the files are stored as BLOB in table FILES. I click on a file name, and then I click on the download button above.
- The download button is simple and af:button with the af:fileDownloadListener component:
- The download listener method is:
- When I click on download, the file is successfully downloaded. However If I expand a treetable node, and then click on the same button, everything on the page freezes (cannot click any component on the screen) and the download method isn't even triggered.
- On the log there are no errors, but sometime I get in the log: Circular dependency detected in style af|dvt-timeline. I have searched the documentation and did not understand a thing about this, or whether this is the actual cause of the issue.
Any help / advice is greatly appreciated
Thankful and appreciative,
Best Regards,
JDeveloper 12.2.1.2
