Hello,

I recognized some strange behavior while calling a conditional target
with <antcall/>. The goal was a switch between different build modes.
Here's the code:

<project name="test" default="generate" basedir=".">
	<property name="build_mode" value="foo"/>
	<!--  -->
	<target name="init">
		<condition property="build_bar">
			<equals arg1="${build_mode}" arg2="bar" casesensitive="yes" trim="yes"/>
		</condition>
		<echo message="...  property build_bar: ${build_bar}"/>
		<condition property="build_foo">
			<isfalse value="${build_bar}"/>
		</condition>
		<echo message="...  property build_foo: ${build_foo}"/>
	</target>
	<!--  -->
	<target name="generate" depends="init">
		<echo>generate ...</echo>
		<antcall target="generate_foo"/>
		<antcall target="generate_bar"/>
		<echo>finished.</echo>
	</target>
	<!--  -->
	<target name="generate_foo" if="${build_foo}" depends="init">
		<echo>generate foo ...</echo>
	</target>
	<!--  -->
	<target name="generate_bar" if="${build_bar}" depends="init">
		<echo>generate bar ...</echo>
	</target>
</project>

The target "generate_foo" is skipped, with the verbose option I get the
follwing lines:

...
     [echo] ...  property build_foo: true

generate_foo:
Skipped because property 'true' not set.
...

Is this a bug or a feature?

(I can solve my problem by rearranging the tasks, but I'm interested in
 an explanation.)

Stefan
