Hi!
I make list of players of hockey team. I divided that list in three
parts attackers, defenders and goalkeepers. I have playerss in one model.
So I simply walk through players selecting player position.
<f:for each="{players}" as="player" iteration="iterator0">
<f:if condition="{player.position} == 0"> // attackers
<f:then>
<f:if condition="{iterator0.isOdd}">
<f:then>
<tr>
</f:then>
<f:else>
<tr class="even">
</f:else>
</f:if>
<td class="r">{iterator0.cycle}</td>
<td>{player.lastName} {player.firstName}</td>
(...)
<f:for each="{players}" as="player" iteration="iterator1">
<f:if condition="{player.position} == 1"> // defenders
<f:then>
<f:if condition="{iterator1.isOdd}">
<f:then>
<tr class="odd">
</f:then>
<f:else>
<tr class="even">
</f:else>
</f:if>
<td class="r">{iterator1.cycle}</td>
<td>{player.lastName} {player.firstName}</td>
(...)
<f:for each="{players}" as="player" iteration="iterator2">
<f:if condition="{player.position} == 2"> // goalkeepers
<f:then>
<f:if condition="{iterator2.isOdd}">
<f:then>
<tr class="odd">
</f:then>
<f:else>
<tr class="even">
</f:else>
</f:if>
<td class="r">{iterator2.cycle}</td>
<td>{player.lastName} {player.firstName}</td>
(...)
The problem is that
iterator1 starts from (iterator0 + 1),
iterator2 starts from (iterator1 + 1)
but not from 1.
you run the iterators always for the whole array.
your intention to count only the selected (posiotion ==...) items could
not be realized in this way.
Either you build other select queries ( ~ WHERE position == ...) to have
three arrays only with items with current position
or you build up your own iterator you only increase inside the filtering
f:if.
How can I change it?
