Summary	0020641: CodeTools fail on inserting eventhadler via doubleclick in OI with error in FindCodeToolForUsed
Description	Ever 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 Reproduce	On a form have some component. In OI select component, select Events Tab, double-click on some event to create a new event-handler.
Additional Information	This 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. ### TCodeToolManager.HandleException: "Class TFORM1 not found" at Line=1 Col=1 in "F:\LazarusProjecten\u_test.pp" ### TCodeToolManager.HandleException: "Class TFORM1 not found" at Line=1 Col=1 in "F:\LazarusProjecten\u_test.pp" #################### TOICustomPropertyGrid.DoCallEdit for TStringsPropertyEditor Edit=True ### TCodeToolManager.HandleException: "Class TFORM1 not found" at Line=1 Col=1 in "F:\LazarusProjecten\u_test.pp" ### TCodeToolManager.HandleException: "Class TForm1 not found" at Line=1 Col=1 in "F:\LazarusProjecten\u_test.pp" #################### TOICustomPropertyGrid.DoCallEdit for TMethodPropertyEditor Edit=True ### TCodeToolManager.HandleException: "Class TForm1 not found" at Line=1 Col=1 in "F:\LazarusProjecten\u_test.pp"

Ludo Brands 2011-11-07 15:04 developer ~0053891	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 TFindDeclarationTool.FindDeclarationOfPropertyPath unit1.pas PropertyPath="TForm 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.

Mattias Gaertner 2012-01-09 14:25 manager ~0055617	I checked all places, where codetools writes 'unit not found'. Either the error is gone or you should now see which unit is missing.
