Force execution of a rule...

[netsrac69]

Hey Guys,

this is something that has happened to me a thousand times and I try to understand it.

I do have a rule which is running fine - just as an example:

  <rule id="DummyTest">
    <condition type="object" id="DummySwitch" value="on" trigger="true" />
    <actionlist>
      <action type="set-value" id="DummyLamp" value="on"  />
    </actionlist>
  </rule>

This works fine for the first "on" I got on the bus. But if I press "on" a second time, all I got in the log is the following:

1320393107 INFO Object : New value on for object DummySwitch (type: 1.001)
1320393107 INFO Rule : Evaluate rule DummyTest
1320393107 INFO ObjectValue : SwitchingObjectValue: Compare value_m='1' to value='1'
1320393107 INFO Condition : ObjectCondition (id='DummySwitch') evaluated as '1'
1320393107 INFO Rule : Rule DummyTest evaluated as 1, prev value was 1
1320393107 INFO FilePersistentStorage : Writing log'on' for object 'DummySwitch'

Because of the of "evaluated as 1, previous value was 1", the rule behind here is not executed.

I understand the problem, because this could create infinite loops, but is there a was to for the execution of the Rule "DummyTest" whenever I receive a "on" signal?

For several reasons I can not set the DummySwitch to off after the evaluation of the rule.

Thanks….Netsrac

hi,

there is 2 type of <actionlist>
1) the default <actionlist type="if-true">
2) and <actionlist type="on-true">

the first is execute when the condition change in false to true
the second is execute when the condition is true (don't look the previous value)

i think for you, you have to use :

<rule id="DummyTest">
 <condition type="object" id="DummySwitch" value="on" trigger="true" />
 <actionlist type="on-true" >
  <action type="set-value" id="DummyLamp" value="on" />
 </actionlist>
 </rule>

hi,
following analysis I made a mistake it's the opposite:
1) <actionlist type="if-true"> =>  is execute when the condition is true (don't look the previous value)
2) the default  <actionlist type="on-true"> => is execute when the condition change in false to true the second

you have to use <actionlist type="if-true">

sorry ;-)
bye,
Anthony.

Perfect…thanks, this works fine…

I love all those undocumented features…I should better read the code itself :-)

I have added this to documentation. Also re-arranged the section regarding rules for this and other things to be more explanatory.
