Setting Initial PoliticalRelationship with Trigger Attachment

RogerCooper

I am trying to use a foreach loop to set the initial relationship for each nation. When I try this loop, I get an error "Unexpected Exception while setting values for attachment."

  <attachment foreach="$TriggerPlayer$^$TriggerPlayer2$" name="triggerAttachment@TriggerPlayer@@TriggerPlayer2@ToNeutrality" attachTo="@TriggerPlayer@" javaClass="games.strategy.triplea.attachments.TriggerAttachment" type="player">
      <option name="conditions" value="conditionAttachmentTurn1"/>
      <option name="relationshipChange" value="@TriggerPlayer@:@TriggerPlayer2:any:Neutrality"/>
      <option name="uses" value="1"/>
      <option name="when"  value="before:ABidPlace"/>
	</attachment>

When I try testing a single value, I get no error but no change in relationship

  <attachment name="triggerAttachmentEnglandFranceToNeutrality" attachTo="England" javaClass="games.strategy.triplea.attachments.TriggerAttachment" type="player">
      <option name="conditions" value="conditionAttachmentTurn1"/>
      <option name="relationshipChange" value="England:France:any:Neutrality"/>
      <option name="uses" value="1"/>
      <option name="when"  value="before:ABidPlace"/>
	</attachment>

Do I have an error in my code or is there a problem with the way TripleA handles TriggerAttachments when the relationship is "DefaultWarRelation"?

I know I could use Excel and paste text to relationshipInitialize but I am trying to create a generic set of code elements to allow any scenario to have random initial alliances and I would like to avoid using Excel.

If you have the same country in both variableList then you are ending up with a relationship like:

<attachment name="triggerAttachmentEnglandEnglandToNeutrality" attachTo="England" javaClass="games.strategy.triplea.attachments.TriggerAttachment" type="player">
   <option name="conditions" value="conditionAttachmentTurn1"/>
   <option name="relationshipChange" value="England:England:any:Neutrality"/>
   <option name="uses" value="1"/>
   <option name="when"  value="before:ABidPlace"/>
</attachment>

Which may be the cause of your problem with this type of arrangement.

Something to look at.

@wc_sumpton I cut back the variable list so the first list is only England, and the second list is only France and I still get the error.

I suspect that problem is that "defaultWarRelation" is probably just a null value and I can't change a null relationship value with a trigger. Technically this is a bug, but the better solution is the ability to set an explicit default value for politicalrelationship. I will submit a request.

Are you saying that you don't have a '<relationshipInitialize>' section? It relationship are not initialize then there is nothing to set. That is why the trigger is falling. I have tried to set a tank unit to transport infantry, but if I didn't set "isLandTransport" then the trigger would fire but nothing would happen. But if I set "isLandTransport" to false then the trigger would change it to true.

Hope this is helpful.
