  I was afraid you were going to say that. It'll take a while to 
obfuscate the parts that I don't want to make public. I'll send it along 
tomorrow.

The AntForm contains some checkboxes that are supposed to make me keep or omit three particular paragraphs in a document I am writing later in the script. Basically, I use the AntForm to set specific booleans, one for each of the three paragraphs, in a Java source file to true or false. Then, I generate the document with a program that I've written and that program either writes the specified paragraphs or omits them based on the values of the booleans. At least, that's what's SUPPOSED to happen.

For instance, I can set the three booleans to false, true and false respectively via the AntForm and that's exactly how they appear in the Java source file just before I generate the document.  (Then I reset the values to their defaults (all three true) then display them to myself and they are all true.) However, when I write the values of the booleans within the program that is generating the document, they are invariably all true, even if they have been set to different values.

When I add the -verbose and -debug parameters to the Ant Build, I see something that the task that displays the AntForm is done in its proper sequence, namely first within the script. However, the tasks that are to be executed to change the values of the booleans are NOT executed immediately after the AntForm is displayed but after the compile of the Java code. The script is displaying the AntForm and letting me check the checkboxes as I like, then compiling the code and ONLY THEN actually editing the source file to set some of the booleans to false. I think this explains why the switches are always seen as true by the document-generating program: the generator is simply not getting the edited version of the source file.

If I'm on the right track, what is it that I'm not understanding about the execution sequences of tasks within targets? I had assumed that each task within a target would be executed before tasks in other targets were started....
