After finally figuring out my goofy mistake earlier I made some
progress. I have a functioning solution now, but I am puzzled by
some strange behavior I am seeing although I am sure there is a
perfectly reasonable explanation for it. I just can't see it.
I have the following method that creates a name for a checkbox.
tableIndex is bound to the repetition of the table row that
contains the checkboxes.
lastTableIndex is a variable I use to help keep track of when
the column index needs to be reset
colIndex is the column index that I am using for naming purposes.
<...>
<td width="175" align="left" class="black10"
style="padding:3px 0px 3px 2px;">Dog 2</td>
<td align="center"></td>
<td align="center"><input type="checkbox" name="r1c1"
value="0.37.10.18.1.5.0"></td>
<td align="center"><input type="checkbox" name="r1c3"
value="0.37.10.18.1.7.0"> </td>
<td align="center"><input type="checkbox" name="r1c5"
value="0.37.10.18.1.9.0"></td>
<td align="center"></td>
</tr>
Notice how the columns count by two? Anyone have any idea why
that might be?
Yes, you are incrementing a variable that is already being
incremented by WORepetition. So it's doubly incremented per item.
How would colIndex be incremented by the WORepetition. It's not
bound to anything. I actually tested the method after removing the
colIndex++ line and nothing is incremented. I get results like
r1c1, r1c1, r1c1, r2c1, r2c1, r2c1. It's almost like the method is
reentrant or something.
It is definitely getting called more than once. Is that method used
in some other binding (a test one you have forgotten about?) in the
WOD? You can also try adding this to the method:
NSLog.out.appendln(new RuntimeException("backtrace"));
To get a back trace from when it gets called.
