Cannot cast TriggerAttachment to RulesAttachment

[Jason Green-Lowe]

I'm getting a new (to me) error message for one of my custom triggers, and I don't understand what it means or how to fix it.

The error message is:
Could not parse:file:///C:/Users/jason/triplea/downloadedMaps/bbr5/games/bbr5.xml, map name: 'file:///C:/Users/jason/triplea/downloadedMaps/bbr5/games/bbr5.xml', Unexpected Exception while setting values for attachment: TriggerAttachment attached to: PlayerId named:Germans with name: triggerAttachment_Germans_AttemptMatureTech_0, Cannot cast games.strategy.triplea.attachments.TriggerAttachment to games.strategy.triplea.attachments.RulesAttachment java.lang.ClassCastException: Cannot cast games.strategy.triplea.attachments.TriggerAttachment to games.strategy.triplea.attachments.RulesAttachment

The code triggering this error is:

    <attachment foreach="$MatureTechDice$:$MatureTechOdds$^$AllTechPlayers$" name="triggerAttachment_@AllTechPlayers@_AttemptMatureTech_@MatureTechDice@" attachTo="@AllTechPlayers@" javaClass="games.strategy.triplea.attachments.TriggerAttachment" type="player">
      <option name="chance" value="@MatureTechOdds@:100"/>
      <option name="trigger" value="triggerAttachment_@AllTechPlayers@_DiscoverTech"/>
      <option name="trigger" value="triggerAttachment_@AllTechPlayers@_ClearTech"/>
    </attachment>

Note that MatureTechDice and MatureTechOdds are each a <variableList> containing 11 variables, each of which is a string containing a positive integer, and AllTechPlayers is a <variableList> containing 8 variables, each of which is a string containing the name of a player.

This is a relatively complicated trigger, with double-nesting, but I have not had any problems with this type of nesting elsewhere in my code, and I don't understand what's going wrong here.

Does anyone have any advice?

Try swapping these around so AllTechPlayers is first. IIRC it matters that the paired variables lists must be the second set.

"$AllTechPlayers$^$MatureTechDice$:$MatureTechOdds$"

@thedog Thanks, but I tried that already -- got the same error message.

It doesn't seem to be a problem with the foreach mapping at all -- I get the same error message when I remove all the variables:

    <attachment name="triggerAttachment_Germans_AttemptMatureTech_2" attachTo="Germans" javaClass="games.strategy.triplea.attachments.TriggerAttachment" type="player">
      <option name="chance" value="2:100"/>
      <option name="trigger" value="triggerAttachment_Germans_DiscoverTech"/>
      <option name="trigger" value="triggerAttachment_Germans_ClearTech"/>
    </attachment>

The immediate problem was that I can't use "trigger" inside a triggerAttachment; the correct syntax is "activateTrigger."

However, I'm still getting an error message, although now it's a new error message. Here's the relevant code:

 <attachment foreach="$AllTechPlayers$^$Technologies$" name="triggerAttachment_@AllTechPlayers@_DiscoverTech" attachTo="@AllTechPlayers@" javaClass="games.strategy.triplea.attachments.TriggerAttachment" type="player">
          <option name="conditions" value="conditionAttachment_@AllTechPlayers@_IsDeveloping_@Technologies@"/>
          <option name="playerAttachmentName" value="RulesAttachment" count="conditionAttachment_@AllTechPlayers@_HasDeveloped_@Technologies@"/>
          <option name="playerProperty" value="switch" count="true"/>
    </attachment>

<attachment foreach="$AllTechPlayers$^$Technologies$" name="triggerAttachment_@AllTechPlayers@_ClearTech" attachTo="@AllTechPlayers@" javaClass="games.strategy.triplea.attachments.TriggerAttachment" type="player">
          <option name="playerAttachmentName" value="RulesAttachment" count="conditionAttachment_@AllTechPlayers@_IsDeveloping_@Technologies@"/>
          <option name="playerProperty" value="switch" count="false"/>
          <option name="removeUnits" value="all:tech_token" count="50"/>
    </attachment>

<attachment foreach="$AllTechPlayers$^$Technologies$" name="triggerAttachment_@AllTechPlayers@_AttemptMatureTech" attachTo="@AllTechPlayers@" javaClass="games.strategy.triplea.attachments.TriggerAttachment" type="player">
          <option name="playerAttachmentName" value="RulesAttachment" count="conditionAttachment_@AllTechPlayers@_HasDeveloped_@Technologies@"/>
          <option name="playerProperty" value="switch" count="true"/>
    </attachment>
    
    <attachment foreach="$AllTechPlayers$^$MatureTechDice$:$MatureTechOdds$" name="triggerAttachment_@AllTechPlayers@_AttemptMatureTech_@MatureTechDice@" attachTo="@AllTechPlayers@" javaClass="games.strategy.triplea.attachments.TriggerAttachment" type="player">
      <option name="chance" value="@MatureTechOdds@:100"/>    
      <option name="activateTrigger" value="triggerAttachment_@AllTechPlayers@_DiscoverTech"/>
      <option name="activateTrigger" value="triggerAttachment_@AllTechPlayers@_ClearTech"/>
      
    </attachment>
    
    <attachment foreach="$AllTechPlayers$^$MatureTechDice$:$MatureTechOdds$" name="userActionAttachment_@AllTechPlayers@_Choose_Mature_Tech_Effort_@MatureTechDice@" attachTo="Germans" javaClass="games.strategy.triplea.attachments.UserActionAttachment" type="player">
      <option name="conditions" value="conditionAttachment_@AllTechPlayers@_HasFourTechTokens:conditionAttachment_@AllTechPlayers@_TechActionNotYetUsedThisTurn"/>
      <option name="activateTrigger" value="triggerAttachment_@AllTechPlayers@_AttemptMatureTech_@MatureTechDice@:1:false:false:false:false"/>
      <option name="activateTrigger" value="triggerAttachment_@AllTechPlayers@_TechActionUsed:1:false:false:false:false"/>
      <option name="text" value="BUY_TECH_@MatureTechDice@"/>
      <option name="attemptsPerTurn" value="1"/>
      <option name="costPU" value="@MatureTechDice@"/>
    </attachment>

And here's the error message:

Could not parse:file:///C:/Users/jason/triplea/downloadedMaps/bbr5/games/bbr5.xml, map name: 'file:///C:/Users/jason/triplea/downloadedMaps/bbr5/games/bbr5.xml', Unexpected Exception while setting values for attachment: TriggerAttachment attached to: PlayerId named:Germans with name: triggerAttachment_Germans_AttemptMatureTech_0, failed to set string property value to 'triggerAttachment_Germans_DiscoverTech' games.strategy.engine.data.MutableProperty$InvalidValueException: failed to set string property value to 'triggerAttachment_Germans_DiscoverTech'

Try completing "activateTrigger":

<attachment foreach="$AllTechPlayers$^$MatureTechDice$:$MatureTechOdds$" name="triggerAttachment_@AllTechPlayers@_AttemptMatureTech_@MatureTechDice@" attachTo="@AllTechPlayers@" javaClass="games.strategy.triplea.attachments.TriggerAttachment" type="player">
      <option name="chance" value="@MatureTechOdds@:100"/>    
      <option name="activateTrigger" value="triggerAttachment_@AllTechPlayers@_DiscoverTech:1:false:false:false:false"/>
      <option name="activateTrigger" value="triggerAttachment_@AllTechPlayers@_ClearTech:1:false:false:false:false"/>
</attachment>

Cheers...

Eeey, there we go, that works. Thank you!
