    <p>I am looking if there is an "easy" or simple way to make an array of something, Lets say Icecreams.. this would be a class of icecream with various Attributes (ID, flavour, Size, scoops), i would like to run an array that gathers every ice cream ordered and then searches through this list for any duplicate values (2+ same size)</p> <p>First idea i had was a for loop that creates the array than grabs the ice cream ID for the first instance, and checks its "flavour" against the array, if no duplicate is found the ID is increased by 1 (ID++) and then that Ice creams flavour is ran in the array, if a match is found i would set a Boolean to true.</p> <p>Every approach i seem to take appears to be rather long winded and i haven't got one working as of yet. hoping some fresh/more experienced eyes would help on this.</p> <p>In answer to below; The XML would hold something like below</p> <pre><code>&lt;iceCream id=1&gt; &lt;flavour&gt;chocolate&lt;/flavour&gt; &lt;scoops&gt;5&lt;/scoops&gt; &lt;/iceCream&gt; &lt;iceCream id=2&gt; &lt;flavour&gt;banana&lt;/flavour&gt; &lt;scoops&gt;2&lt;/scoops&gt; &lt;/iceCream&gt; </code></pre> <p>I would want to use drools (probably an array list?) to gather each icecream tag and allow me to check if any of the icecreams have the same flavour and output something (set a boolean to true) if a match is found, My understand was to make an array then run each icecream though the array by using its ID to identify it and inside each loop do ID +1 (int ID = 1) then in the lopp ID++. Aswell as search through the flavour childtag.</p> <pre><code>int ID = 0; boolean match = false; ArrayList iceCreams = new ArrayList($cont.getIceCreams()); for(iceCream $Flavour: (ArrayList&lt;iceCream&gt;)iceCreams) { ID++ if($Flavour.getFlavour().equals(icecream with id of (ID variable).getFlavour) { match = true; } } if(match) {etc etc etc} </code></pre> <p>Something along these lines if this helps?</p>

    1. CONot entirely sure what you are asking. Do you mean something like if `ice_cream[flavor_0] == chocolate` or something like `ice_cream[flavor_0] == ice_cream[flavor_1]`?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
