Summary0020641: CodeTools fail on inserting eventhadler via doubleclick in OI with error in FindCodeToolForUsed
DescriptionEver so often when I want to create an eventhandler (in OI select event, then double-click) I get a failure from CodeTools:
The messagedialog says there is an error and prompts to look in the messages windwow.
There the message is in the form of "Class TSomeClass not found at Line=SomeValue Col=SomeValue" in PathTo\SomeUnit.pp.

Once this has happend, it becomes impossible to use the OI to create new eventhandlers.
Closing and restarting Lazarus temporarily resolves the issue.

It does not happen al the time, but I cannot determine what makes it happen and what not.

(The problem exists from at least r31810)
Steps To ReproduceOn a form have some component.
In OI select component, select Events Tab, double-click on some event to create a new event-handler.
Additional InformationThis is an excerpt form my lazarus log, the last time this happened.
I just placed an ActionList on a form which also has 1 TButton (which has an OnClick-handler).
I then opened the ActionList-editor and created 2 actions.
After that I selected the actionlist in OI and double-clicked on "OnExecute" and the error occurred.

I'm also getting this frequently. Mostly when creating a new application or re-opening an existing application after having worked quite some time on an app (debugging, etc.). Just had the problem again when creating a new application and double clicking on the form to create the OnCreate event. Message:
\lcl\forms.pp(1706,14) Error: [TFindDeclarationTool.FindCodeToolForUsedUnit] internal error: invalid UnitNameAtom

Console output (recompiled the ide with -WG-):

TDesigner.InvokeComponentEditor A Form1:TForm1
TDesigner.InvokeComponentEditor B TDefaultComponentEditor
TEventsCodeTool.PublishedMethodExists method not found FormCreate
[TEventsCodeTool.CreateMethod] A AMethodName="FormCreate" in "unit1.pas" UseType
InfoForParameters=False

1.OnCreate"
### TCodeToolManager.HandleException: "[TFindDeclarationTool.FindCodeToolForUsed
Unit] internal error: invalid UnitNameAtom" at Line=1706 Col=14 in "C:\lazarus\l
cl\forms.pp"
TMainIDE.OnPropHookCreateMethod failed adding method to source
TDesigner.InvokeComponentEditor ERROR: Unable to create new method. Please fix t
he error shown in the message window, which is normally below the source editor.

This message is coming back regularly but I have seen others, all pointing to codetools not finding something or detecting a syntax error where there isn't.
Quitting and restarting lazarus is the only way to solve this.
I'm using now trunk 33356 but this happens since several weeks now. XP Sp2.

Actually, in the last 10 minutes I reproduced the problem 3 times but haven't found a reproducible sequence of steps. Running and breaking in a reasonable big app, using code tools (find method declaration, find implementation) are necessary to create the problem.

I have also had this. In my case choosing rescan FPC sources helped, even though I have not changed any sources.

 This error popped up again (this time by double-click on Button2).
Lazarus 0.9.31 r34638 FPC 2.6.0 i386-win32-win32/win64
I'll attach screenshot and possible relevant files (env. options, current project).

I checked all places, where codetools writes 'unit not found'. Either the error is gone or you should now see which unit is missing.
