| 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,

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 '[<CustomerSummary name: CustomerSummary subcomponents: {0.15.13.7.1.5.0.1.3 = <er.ajax.AjaxExpansion name: er.ajax.AjaxExpansion subcomponents: null >; 0.15.13.7.1.7 = <er.ajax.AjaxModalDialog name: er.ajax.AjaxModalDialog subcomponents: null >; } > takeValueForKey()]: attempt to assign value to unknown key: 'isAgreementDetailsVisibleForBundleProductItem'.
