I'd like to ask whether using a xacro parameter value in xacro macros is allowed, because it is not clear from the docs [http://www.ros.org/wiki/xacro]. Consider a simplified version of my file, which fails on ros-latest from binary packages:
<xacro:parameter name="the_param" value="1" />
<xacro:macro
name="macro1" >
<foo>${the_param}</foo>
</xacro:macro>
<xacro:macro name="macro2" params="macro2_param" >
<mechanicalReduction>${macro2_param}</mechanicalReduction>
</xacro:macro>
<xacro:macro1 /> <!-- Fails
-->
<xacro:macro2 macro2_param ="${the_param}" /> <!-- Fails
-->
The two above lines raise a XacroException that states " Property wasn't defined: u'the_param' " when xacro is run. Is this expected behavior?.
TIA,
Adolfo
