Map() in the .drl file is bound to be interpreted as Map<Object,Object> so that a Map.get() returns an Object. To be able to call method getSomeMethod() you'd have to cast this result, according to<br><br> ((SomeClass)$map.get("x")).getSomeMethod()<br>
<br>I fail to understand how this could ever be avoided - strict or no strict, MVEL or not MVEL.<br><br>-W <br><br><div class="gmail_quote">2009/10/2 Vladimir Perlov <span dir="ltr"><<a href="mailto:vladperl@hotmail.com">vladperl@hotmail.com</a>></span><br>

Hi Wolfgang,<br>Thank you very much for quick response!<br><br>I tried your suggestion and still getting the following error:<br><br><h3>Unable to build expression for 'consequence': Failed to compile: 1
compilation error(s): - (1,29) unable to resolve method using
strict-mode: java.lang.Object.getSomeMethod() '
System.out.println($map.get("x").getSomeMethod());
' : [Rule name='TEST']
</h3>At least now I have only 1 compilation error comparing to the previous variant.<br><br>modified rule:<br><font face="Courier New"><br></font><font face="Courier New">rule "TEST"</font><font face="Courier New"><br>
</font><font face="Courier New"> dialect "mvel"</font><font face="Courier New"><br></font><font face="Courier New"> when</font><font face="Courier New"><br></font><font face="Courier New"> $map : Map()</font><font face="Courier New"><br>

<br>I believe that problem is related to strict-mode that somehow enforced on Linux but not on Windows.<br>I tried to remove the strict mode using the the following approach but it seems don't have any effect.<br>We have web application with many drools rules and it's working on Windows but when we deployed the same application to Linux we are getting failed compile errors ;) <br>
<br><font face="Courier New">KnowledgeBuilderConfiguration config = KnowledgeBuilderFactory.newKnowledgeBuilderConfiguration(); </font><font face="Courier New"><br></font><font face="Courier New">config.setProperty("drools.dialect.mvel.strict", "false");</font><font face="Courier New"><br>
</font><font face="Courier New">kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder(config);</font><br><br>Please advise me.<br><br>By the way I'm using drools 5.0.1<br><br><br><hr>Date: Fri, 2 Oct 2009 18:30:25 +0200<br>
