Use System Variable when referring to Resources
by srikanthmalli
Hi,
Is it possible to use System variable when referring to Resources in
Drools-Spring integration?
<drools:kagent id="kAgent" kbase="kBase" new-instance="false">
<drools:resources>
<drools:resource type="PKG"
source="file:/C:/Guvnor-Repository/Sample_v1.PKG">
</drools:resource>
</drools:resources>
</drools:kagent>
<drools:kagent id="kAgent" kbase="kBase" new-instance="false">
<drools:resources>
<drools:resource type="PKG"
source="file:${SYS_VAR_RULE_PKG_DIR}/Sample_v1.PKG">
</drools:resource>
</drools:resources>
</drools:kagent>
Thanks,
-Sri

Guvnor 5.5.0.Final Web decision table's advanced enum is not working.
by Soumya.plavaga
Hi,
We are trying to use the advanced enumeration with guvnor 5.5.0.Final. But
seems not working for us. We are doing this -
Having model cascadedModel. CascadedModel has following fields -
1. categoryField (Type Text)
2. departmentField. (Type Text)
Cascaded model has a fact called -
cascadedFact.
Created an enum called cascadedEnum having following -
Fact => 'cascadedFact'
Field => 'categoryField'
Context => '(new
com.ugamsolutions.projectname.guvnorhelper.CategoryListing()).getAttributeListByName("categoryName")'
Fact => 'cascadedFact'
Field => departmentField[categoryField]
Context => '(new
com.ugamsolutions.projectname.guvnorhelper.DepartmentListing()).getAttributeListByNameAndCategoryIdString("departmentName","@{categoryField}")'
And using these two enums in a web decision table's drop down. First drop
down suppose to display all the categories returned for 'categoryField' and
second dropdown will return the departments based upon category dropdown
selection.
Here my case Category drop down is listing properly, no issues. But upon
category selection department dropdown is not loading at all. Actually I can
see '{@categoryField} in enum is not replacing the primary drop down's
selected value. Can you please take a look and let me know if there is any
issue with the advanced dropdown with web decision table in guvnor
5.5.0.Final war?
Any help will be really appriciated.
Many Thanks,
Soumya

Synchronization issue in Guvnor Cluster Setup
by kulpreet_singh
Hi,
I am trying to setup a cluster for two guvnor 5.3.0 instances. I deployed
two different guvnor wars instances (different context roots) on WAS CE
2.1.1.4 server. Then, configured common/shared file based journal for both
guvnor repositories (added cluster node in repository.xml file of both
guvnor instances). But, when working on one Guvnor instance, the
corresponding updates are not reflected on other guvnor’s repository.
However, the journal log is updated with activities in both the Guvnor
repositories. I also tried by adding <distributable/> element as a child
element of the web-app element to the both Guvnors' web.xml file, but still
the synchronization issue is not resolved. Please let me know if I am
missing any configuration for cluster setup.
Thanks & Regards,
Kulpreet Singh

Issue with simple accumulate sum rule
by stelomax
I am having an issue with a very (VERY) simple rule.
This is being called from a rule flow. There are 2 "Testval" facts, both
have an "xval" of 300. When the flow is executed i get the following output
Total xval: 0.0
300
Total xval: 0.0
300
This shows me a few things
1) The rule is firing
2) My facts are populated correctly with values
However the Sum is not working and always has a result of 0.0.
------------------------------------------------------------------------------------
dialect "java"
ruleflow-group "TestSum"
when
Testval($xval2:xval)
$total:Number() from accumulate(
Testval($xval:xval),
sum($xval)
)
then
System.out.println("Total xval: " + $total);
System.out.println($xval2);
-----------------------------------
I simplified the rule to see if i was loosing my mind. With the below rule
the sum works correctly (as it is summing the static value (1). And i get
the following output:
Total xval: 2.0
------------------------------------------------------------------------------------
dialect "java"
ruleflow-group "TestSum"
when
$total:Number() from accumulate(
Testval($xval:xval),
sum(1)
)
then
System.out.println("Total xval: " + $total);
-----------------------------------
I have been racking my brain for a full day now..any pointers would be
great!
Thanks gurus
Steve
