<div>Hi Felipe,</div><div><br></div><div>thank you for bearing with me.</div><div><br></div><div>actually I put an eval() there just to have something as simple as possible(but couldn't be sure it it worked). </div><div>
<br></div><div>I actually found a hello world example which works fine without being template and which I will now try to transform it into template form. I suspect I'm not passing parameter correctly, somehow.</div><div>
<br></div><div>I will unfortunately be away for the next 10 days, so will revert only later and hopefully on a better example than my original.</div><div><br></div><div>Thanks. Stefan</div><div><br></div><div class="gmail_quote">

Im not sure if you can find a complete standalone example for this, but I think your problem now is with eval().<br><br>Can you copy your stackTrace here?<br><br>I think you can not do eval( literal == literal),<br>but you could make a function to test that if you wanna use eval and give the function the value of @{symbol}<br>

Hi Felipe,<div><br></div><div>thank you for your reply. I have now added the extra quotes but to no avail. I still get the same errors.</div><div><br></div><div>Is there somewhere a stand-alone example with the compile instructions to check that everything works? I have the impression that I'm having troubles with the whole eclipse config and plugin.</div>

if you have a value in the example will be replaced as text in the rule and you will have something like this:<br>
<br>if @{symbol} == "THE_SYMBOL"<br><br>==><br><br><div>rule "A stand alone rule THE_SYMBOL"</div><div><span style="white-space:pre"> </span>dialect "mvel"</div><div><span style="white-space:pre"> </span>when</div>

<div>end</div>----------<br><br>So as you can see, the variable is no more a variable in the generated rule, just text, so if you wanna use it as a string, you should add double-quote<br>(")<br><br>your rule template should be something like this:<div>
