Description Alexander Simon 2012-12-26 07:50:58 UTC 
Steps to reproduce:
- create C/C++ application
- Debug->Debug Core File
- type in field "Core File" "/net/qq"
- press Browse button
Expected behavior:
- File chooser dialog is appeared in one second.
Actual behavior:
- Dialog is appeared after 10-30 seconds. User can click browse several times and dialog will be shown several times.
Comment 1 Egor Ushakov 2013-04-30 14:17:48 UTC 
we use FileChooserBuilder and it calls file.exists on chooser create, it causes huge slowness before dialog even appears
Comment 2 Maria Tishkova 2013-05-14 13:24:55 UTC 
From what I found the problem is not only in the FileChooser. 
The first problem I see is in validation of values in DebugCorePanel
Comment 3 Maria Tishkova 2013-05-14 15:51:13 UTC 
3 fixes:

1. DebugCorePanel: validation worker introduced which will validate all values in one separate request processor and will be re-scheduled and canceled when needed

see http://hg.netbeans.org/cnd-main/rev/60aa696596c6

2. dlight.remote: FileChooserUI copied from DirectoryChooserUI (no way to re-use) to get files list in separate request processor and update UI when prepared

see http://hg.netbeans.org/cnd-main/rev/a10ba91b7bfe

3. dlight.api: RemoteFileUtil createFileChooser and createProjectChooser should both user dlight.remote.FileChooserBuilder

see http://hg.netbeans.org/cnd-main/rev/d6052ae7f57f
Comment 4 Maria Tishkova 2013-05-15 11:50:13 UTC 
additional fix: show Loading... in tree
