Save Failed Position.point when saving a scala file

Hello,

I'm using Helios and Scala IDE version 1.0.0.201008182333.

While saving a scala file I recieved an error stating "Save Failed Position.point". This problem seems to only affect one of my files, the rest are able to be saved normally.

The stack trace from the eclipse log file is:

!ENTRY org.scala-ide.sdt.core 4 4 2010-08-20 20:16:34.148

It would be really great if you could give us a minimal version of that file so we can reproduce it.

Below is the code. To reproduce I
1. Delete the quote at line 9 character position 18.
2. Save the file
3. Add a space so the file is modified.
4. Attempt to save should produce the error.
Note: To remove the error Replace With -> Previous from Local History

package test

import scala.xml._

object SaveErrorTest {
def writeXml(foos :Array[String], goos :Array[String], hoos :Array[String]):Elem = {
<xml>
{ for (foo <- foos) yield
<foo att1={"" + "test"+ "" } att2={"" + foo + ""} att3={"" + foo + ""}>
</foo>
}
{ for (goo <- goos) yield
<goo>
</goo>
}
{ for (hoo <- hoos) yield
<hoo>
</hoo>
}
</xml>
}
}

I got exactly the same error. Wanted to check out if it is worth using Eclipse for Scala. The first File I create can't even be saved after writing 4 Lines. So : Evidently not. Back to IntelliJ then.

Status changed from New to Invalid

Closing as invalid.

I cannot reproduce the problem with the first test case on both 2.0.0-2.9 and master-2.10. The second test case doesn't seem to be valid Scala.
This has likely been fixed during 2.0 development.

Please reopen with additional information if you still see the problem.
