Working with collections
by Marcin Krol
Hello everyone,
I'm a beginner in Drools, so please account for that. :-)
How do I use memberOf operator when working with collections? Depending
on a day of week, I want to check if a day is a working day or weekend day.
I tried this:
package com.sample
dialect "mvel"
import com.sample.ThermostatTimeData;
import com.sample.Thermostat.WorkDay;
import com.sample.Thermostat.WorkDays;
rule "Rule 1"
when
$wd : WorkDays()
$ttd : ThermostatTimeData( day memberOf $wd.daylist )
//$ttd: ThermostatTimeData ( day == "Monday" || day == "Tuesday" || day
== "Wednesday" || day == "Thursday" || day == "Friday" )
then
insert( new WorkDay() );
System.out.println("inserting new workday");
end
with this in my Thermostat class:
public static class WorkDays {
private String[] dl = {"Monday", "Tuesday", "Wednesday", "Thursday",
"Friday"};
public WorkDays() {
}
public String[] getDaylist() {
return this.dl;
}
}
Now the above rule works fine when I select days using the regular fact
field selection in Drools:
$ttd: ThermostatTimeData ( day == "Monday" || day == "Tuesday" || day ==
"Wednesday" || day == "Thursday" || day == "Friday"
However, when I try to access WorkDays.dl or WorkDays.daylist(), the
rule doesn't fire (the program output is empty).

to have some hierarchical control over rules in the same package
by hongyu lu
Hi,
I have a use case where I would like to group rules by package(each package would be one experiment in my app). There are a couple attributes at the package level, which will enable/disable all rules of that package(not being fired). What would be the best way to achieve this? I am new to Drools and it looks like the rule definition is kinda flat. I would like to avoid defining package level conditions within each rule.
thanks

RE: Category Tree Display Overlaps the box area in Guvnor in Internet Explorer
by Vikrant Yagnick
Actually, this is pretty much a blocker bug for Internet Explorer as I am unable to add a name to a new rule, if my category is in the lower half of the list.
Anybody, have any ideas on how this can be worked around or solved?

Hi All,
I am not sure, if this has been raised before(could not find an existing JIRA) for it.
The display of categories in IE 7 seems to overlap the box area(See attached).
This works correctly with Safari and FireFox. Sounds like a problem with Z-Indexes in IE.
Cheers,
