<br> Felipe,<br><br> The NPE is a bug that was fixed already.<br> I can't think in another way of doing without using a return value restriction as you are doing... <br><br> []s<br> Edson<br><br><div><span class="gmail_quote">

<div style="">Hi,<div><br></div><div> Im trying to compare a field to a Class type but when parsing I get NPE and when I debug,</div><div>the constraint is a ReturnValueConstraint but the <font color="#0000c0" face="Monaco" size="3">
<span style="font-size: 11px;">restriction</span></font><font face="Monaco" size="3"><span style="font-size: 11px;">.getRequiredDeclarations()</span></font> </div><div>return a Declaration[] array initializated, but empty, so I can't get the declaration evaluated...
</div><div>I needed because I'm working on a kind of parser for the rules for analisys and testing... but using </div><div>the already parsed package.</div><div><br></div><div>Here is a pseudo rule for test...</div><div>
<br></div><div style="margin: 0px;"><font color="#960000" face="Monaco" size="3"><span style="font-size: 11px;">rule</span></font><font face="Monaco" size="3"><span style="font-size: 11px;"> </span></font><font color="#008000" face="Monaco" size="3">
<span style="font-size: 11px;">"Test A"</span></font></div><div style="margin: 0px;"><span style="white-space: pre;"> </span><font color="#960000" face="Monaco" size="3"><span style="font-size: 11px;">when</span>
</font></div><div style="margin: 0px;"><span style="white-space: pre;"> </span><span style="white-space: pre;"> </span><font face="Monaco" size="3"><span style="font-size: 11px;">$mf: MyFact(clazz == (SomeClass.class))</span>
</font></div><div style="margin: 0px;"><span style="white-space: pre;"> </span><font color="#960000" face="Monaco" size="3"><span style="font-size: 11px;">then</span></font></div><div style="margin: 0px;"><span style="white-space: pre;">
</span><span style="white-space: pre;"> </span><font face="Monaco" size="3"><span style="font-size: 11px;">System.out.println(</span></font><font color="#008000" face="Monaco" size="3"><span style="font-size: 11px;">"Test A: OK"
</span></font><font face="Monaco" size="3"><span style="font-size: 11px;">);</span></font></div><div style="margin: 0px;"><font color="#960000" face="Monaco" size="3"><span style="font-size: 11px;">end</span></font></div>
<div><br></div><div>Actualy, the rule compiles (with the NPE output, not stackTrace, just the <font color="#000080" face="Monaco" size="3"><span style="font-size: 11px; text-decoration: underline;">java.lang.NullPointerException
</span></font>, </div><div>and it works fine.. I mean I get "Test A: OK" as output, but cant get the SomeClass.class reference when I</div><div>look into the debugger.</div><div><br></div><div>Is this the right way to compare clases? if not, whats the right way? (Im trying to not do == "SomeClass")
