Dear List,
I tried to solve the problem of using the AjaxExpansion per row inside a
repetition and providing a unique "expanded" flag binding per row.
Since each row matches a particular product, the binding of "expanded" is set
to the visible flag of each product in the array by using a setter/getter
method.
If I use a public instance variable, such as a global "isVisible" flag, this
would work like the AjaxExample, but the global instance variable is not
suitable for each row in a repetition.
I do not understand why the binding to a setter/getter method would fail?
Thanks for any hints,
-mai
CurrentProductRepetition: WORepetition {
item = bundleProductItem;
list = currentMainBundleProducts;
index = logIndex;
}
AgreementDetailsAjaxExpansion : AjaxExpansion {
id = ~"AgreementDetailsAjaxExpansion" + logIndex;
insertion = "Effect.blind";
insertionDuration = "0.1";
string = "Agreement Details";
expanded = isAgreementDetailsVisibleForBundleProductItem;
}
In the java file, I have the following simple code:
public boolean isAgreementDetailsVisibleForBundleProductItem() {
return (bundleProductItemC.isAgreementDetailsVisible());
}
public void setIsAgreementDetailsVisibleForBundleProductItem(boolean aValue) {
bundleProductItemC.setIsAgreementDetailsVisible(aValue);
}
==
// Methods used in AjaxExpansion for bundle product
public boolean isAgreementDetailsVisibleC = false;
public boolean isAgreementDetailsVisible() {
return isAgreementDetailsVisibleC;
}
public void setIsAgreementDetailsVisible(boolean value) {
isAgreementDetailsVisibleC = value;
}
However, at runtime, I would get the following exception:
<com.webobjects.foundation.NSKeyValueCoding$UnknownKeyException message
