Hi,
this post is yet another great example why community works

I had the same issue, walking through the comments I found Brooks Hollar comment and yes, when you concat a String and have linebreaks in your src, this compiler error occurs.
example:
SQLString += “VALUES (” + row.PersonId + “,”
+ row.expenseAllowance + “,”
+ row.probableCustomer;
I’m using Flex Builder 3.0.2.214194 and Flex SDK 3.4.0.9271

on my way to Jira

Thanks for taking the time to document all this.

I just have to vent and say: what a pathetic excuse for a compiler! So “Internal build error” could mean that somewhere, anywhere, lurks a missing semicolon or some such, and it’s up to the poor human to search every line of the source code for the offending line?

I am seriously ready to give up on Adobe products and just do C# & Silverlight. I don’t care if Flex pays better, this kind of aggravation is just not worth it.

Adobe had better get this right with the next release, or I’m out the door.

In my case a bindable variable created this problem.

[Bindable]
private var ddArrColl:ArrayCollection;

and used somewhere as a dataprovider for a list;

then i changed to

[Bindable]
private var ddArrColl:ArrayCollection = new ArrayCollection();

Bingo..!!!

[...] new bug by any account and from my research seemed to be particularly prominent in Flex Builder 2. This article which lists a few of the reasons which this may happen is very useful and I’ve just noticed [...]

I had a free floating variable like this declared in an ActionScript file

public var xmlAttrList:XMLList = loadedXml.books.book.authors.author.(@first == “Monica”);

I was including this .as file in a .mxml file. The compiler didn’t like the E4X filtering (although other more basic E4X features seemed to work)

The fix was to do such E4X operationswithin a function that is explicitly called as part of handling some event.. in this case I put it in an mx:Application initialize event handler function.

I just started learning Flex and am still trying to figure out scoping, the order of processing of declarations, compilation etc… Hopefully I’ll understand this better in a few days/weeks.

We isolated the issue to be with shape tween in a swc.

I had the same error too. In my case problem occurred while I was trying to define two methods with different namespaces in my class. After different manipulations to fix this I was tired and confused. Last thing I did was the cleaning project and error has gone For now I don’t know why this error occurred to me… Maybe, someone has the same situation?

Spent a long time trying to track this down. For me it came down to: UPDATE THE COMPILER VERSION from within FlexBuilder. There was code that wasn’t running properly in the older version.

In my case (and from what i have read here this might be true for others) it was a COMBINATION of +2 problems:

1. i had errors in my code (i dont think it matters which errors, for what its worth, they were in a file of the same package as in 2.)
2. i had an .as file in my structure with a wrong package name

when i removed the file it showed me the other errors.
so for me it comes down to a copy-file-mishap..
