Problems with Javascript in Tapestry 4.1.5
Hi all,
We moved from tapestry 4.0.2 to 4.1.5
we were using a script file and in had used the
<initialization></initialization> tag to initialize the values used in
script functions.
The variables defined in this tag were working as global variable and we
used to get the value of these variables in any script function.
After shifting to 4.1.5 the initialization is treated as a different
function and so the variables defined there are local to it, these variables
loose there values as we try to access them in different script functions.
the code is as follows
<initialization>
var thArray = new Array();
<foreach key="th" expression="ths">
thArray[t++] = new Th("${th.thId}", ${th.position});
</foreach>
swapThArray();
</initialization>
function swapThArray() {
var tswap = thArray.length;
for (var k = t; k < t + (thArray.length - t - 1)/2; k++) {
var tempth = thArray[--tswap];
thArray[tswap] = thArray[k];
thArray[k] = tempth;
}
}
getting a javascript error in swapThArray that thArray has no properties
thanks in advance,
regards,

In 4.0.2 the initialization code was being placed in open on the page. But
in 4.1.5 the initialization code is placed into a function and hence the
variable looses its reference. Hope that helps.
Srini.

You need to do something like:
document.thArray = new Array();
