[rules-users] java.util.NoSuchElementException in buildAsset
Hi,
I have installed BRMS (Drools 5) and create a repository for BRMS. When
I create a simple rule, like:
when
$object: Object()
then
System.out.println("ok");
end
all works fine, but... When I create a complex rule, using my own complex
classes and click in the validate button, the following error is reported
:
Error
An error occurred executing the action.

Subject: [rules-users] problems with desicion tables
Hi,
I am working with decition tables, I have differents xls files with
rules and I want to add multiple xls files to the same rulebase and
they will be merged into a single package.
I do the following:
private static RuleBase readTablaDecision() throws Exception {
//read in the source
final SpreadsheetCompiler converter = new SpreadsheetCompiler();
final String drl = converter.compile( "/reglaPrincipal.xls",
InputType.XLS );
PackageBuilder builder = new PackageBuilder();
builder.addPackageFromDrl( new StringReader( drl ) );
final String drl2, drl3;
if((dj.getVersion()!=null)&&(dj.getVersion().compareTo("Version
1")==0)){
drl2 = converter.compile( "/reglaVersion1.xls",
InputType.XLS );
builder.addPackageFromDrl( new StringReader( drl2
) );
}
Package pkg = builder.getPackage();
RuleBase ruleBase = RuleBaseFactory.newRuleBase();
ruleBase.addPackage( pkg );
return ruleBase;
}
When I run the program, the following error message appear:
org.drools.compiler.PackageBuilder$PackageMergeException: Can't merge
packages with different names. This package: com.ReglaPrincipal - New
package: com.reglaVersion1

Re: [rules-users] generic properties
Hi,
you can try using "eval"
when
$io:InputObject()
eval($io.getStringPropertyValue("propertyname")=="something")
then

Re: [rules-users] How to check for a variable number of "conditions" ina rule?
Ron, if your global is set before ***asserting facts to the working memory and not changed anymore, you can use it. Also, make sure your array or whatever is an attribute of a class, and so has some semantic to it. You can do things like this: when MyArrayContainer( $flags : flags ) Number( intValue >= SOME_GLOBAL_THRESHOLD ) from accumulate( $f : Flag( value == SOME_GLOBAL_VALUE ) from $flags, count( $f ) ) then // threshold met end Another options is just create a holder class for your globals and assert it as a fact instead of using globals: when MyParameters( $threshold : threshold, $value : value ) MyArrayContainer( $flags : flags ) Number( intValue >= $threshold ) from accumulate( $f : Flag( value == $flags ) from $flags, count( $f ) ) then // threshold met end Hope it helps, Edson 2008/7/23 Ron Kneusel <[EMAIL PROTECTED]>: > > Mike, > > I think the collect will work, I'll have to look at it more closely because > the ordering of elements in the array is significant so I'm not sure I can > just break the elements up into facts and let collect group them however it > will. > > As a follow up, while my solution of using a global in the LHS works, is > the problem with changing the global simply that the engine will not see the > changes?

Re: [rules-users] generic properties
If you make your map available through a get, you can use simplified Map
syntax like this:
public Map getStringParameters() {
return stringParameter;
}
io: InputObject ( stringParameters["propertyname"] == "something")

RE: [rules-users] How to check for a variable number of "conditions" ina rule?
Mike, I think the collect will work, I'll have to look at it more closely because the ordering of elements in the array is significant so I'm not sure I can just break the elements up into facts and let collect group them however it will. As a follow up, while my solution of using a global in the LHS works, is the problem with changing the global simply that the engine will not see the changes? For my case, the global is set before the rules engine is called and it will not change while the engine runs.

I want to use a generic Input-Object for drools which can i.g. access String
