Changes not showing

Whenever I make a small change to my application using the config file I have to do a delete browser history. Really annoying. Do you know a way that I can keep from having to do this? I imagine from time to time after I roll this out I will have some updates for this or at least for the layers.

Thoughts, suggestions or ideas?

It is quite frustrating that this is an issue, and the only fix I know of involves making some changes to the flexviewer source. To me this is a huge issue so I had to learn how to do this.

See these threads to get you started:

This time around, for 3.6, I had to compare the Configmanager.as to the edited one found in that thread and edit accordingly.

It's a big PITA so hopefully something like this will get worked into a future version!

Here is my ConfigManager.as for 3.6. Replace the one in the source and compile and you'll be all set.

I also made the changes to the index.html found in the links above. With these two adjustments all changes are seen immediately on page reload.

Thanks for this 3.6 file Eric. I've never touched source code or Flash Builder, but I seriously need these maps to not be cached! Going to go muck around in a trial version of FB hopefully, again thanks for these tips.

I think it worked. I'm using the compiled version of ArcGIS Viewer for Flex 3.6, so in case another newb hits this problem, here is exactly what I did. Sorry for the verbose response but I wanted to post this on the off-chance that someone needs a very very simple and obvious step-by-step as a non-developer.

1. Downloaded trial version of Flash Builder 4.7 from Adobe website onto the server where I use ArcGIS Viewer for Flex normally
2. Downloaded Adobe Flex SDK 4.6 from Adobe, which I think was unnecessary because Flash Builder already seemed to have it. Unzipped in C:/Documents.
3. Downloaded Flex API 4.6 library from ESRI and unzipped in C:/Documents
4. Downloaded and DID NOT UNZIP the MASTER source code (see next step) for ArcGIS Viewer for Flex 3.6 from GitHub as a zip file to C:/Documents
5. Backtracked and followed these instructions carefully: http://resources.arcgis.com/en/help/flex-viewer/concepts/
6. Once the FlexViewer project was imported to Flash Builder (see step 5) I ran it with the green Play button and it launched successfully in a browse.
7. From here, in the FlexViewer project folder created by FB (C:\Users\[me]\Adobe Flash Builder 4.7\FlexViewer) I found the index file that needed editing (C:\Users\[me]\Adobe Flash Builder 4.7\FlexViewer\html-template\index.template) as well as MapManager.mxml (C:\Users\[me]\Adobe Flash Builder 4.7\FlexViewer\src\com\esri\viewer\managers\MapManager.mxml) and edited it in Notepad++. I took the changes from the Forum post listed above: http://forums.arcgis.com/threads/57121-browser-cache. Finally I copied in Eric's 3.6 ConfigManager.as to overwrite the one in there (C:\Users\[me]\Adobe Flash Builder 4.7\FlexViewer\src\com\esri\viewer\managers\ConfigManager.as).
8. I refreshed the FlexViewer project in Flash Builder (I had no idea what I was doing but I had changed files so I figured I should) and then I hit the green play button. A dialog ran saying it was performing a build and mentioned compiling, so I waited.
9. When it was done I went to the output folder for the project to copy what I hoped were the compiled files (C:\Users\[me]\Adobe Flash Builder 4.7\FlexViewer\bin-debug), where bin-debug is that default output folder. I was slightly disturbed that the files' last updated times were from earlier and not since the latest project build...but I moved on, partly because earlier I had also manually changed the index.html file in this folder in addition to the index template.
10. I coped the index Shockwave Flash Object file, and all of the .swz extension files, from the FlexViewer project folder. I then went to my app folder for the web map I had already created using the compiled ArcGIS Viewer for Flex (C:\inetpub\wwwroot\Apps\exampleMap) and overwrote its files with these ones. I tested it in Chrome and after hitting refresh the map was updated with a change I had made in the logo.
