EricVlach Best Practice Suggestions? adding multiple child objects
I need suggestions from the pros - every time I start implementing a possible solution, I run into problems.
I have License object, with License Feature child object. (A software license, on which one or more license features can be added to increase the product capabilities.)
The license feature names come from a list in my controller. Here is what I would like my form to look like: (check to toggle date box)
| Feature Name | Expiration Date |
|---|---|
| Feature A | |
| Feature B | |
| Feature C |
Upon save, the License object would be created, as well as those features which are CHECKED. I can do this very easily if I code for each license feature independently. However, being the good programmer that I am, I am looking to write the code for the quickest implementation of future additional features. All I would do is add an item to a List of features, and the rest would auto-generate. Here is my latest attempt:
<apex:dataTable columns="2" value="{!AllLicenseFeatures}" var="feature">
<apex:column>
<apex:facet name="header">Available Features</apex:facet>
<apex:inputCheckbox value="{!feature.name}" id="feature{!feature.name}" onChange="toggle('feature{!feature.name}Expiration')" />
</apex:column>
<apex:column>
<apex:facet name="header">Expiration Date</apex:facet>
<apex:InputField id="feature{!feature.name}Expiration" value="{!feature.Expiration_Date__c}" />
</apex:column>
</apex:dataTable>
Current Problem: variable from the apex:dataTable tag is not usable in the apex:InputField or apex:InputCheckbox - it is looking for a controller class called feature, instead of using the variable.
Error messages returned by the compiler:
Error Error: id="feature{!feature.name}" core.apexpages.quickfix.QuickFixException: Unknown property 'newLicenseController.feature'
Quick Fix Create Apex method 'newLicenseController.getFeature'
Error Error: Unknown property 'newLicenseController.feature'
How do I get those apex tags to refer to the dataTable variable feature, not a controller method feature!?
List<String> feature_names = new List<String>{'Feature A','Feature B','Feature C'};
License_Feature__c[] features = new License_Feature__c[feature_names.size()];
public License_Feature__c getLicenseFeature(Integer i){
if (features[i] == null) features[i] = new License_Feature__c();
return features[i];
}
public License_Feature__c[] getAllLicenseFeatures() {
integer i;
for ( i = 0; i < feature_names.size() ; i ++) {
features[i] = getLicenseFeature(i);
features[i].name = feature_names[i];
}
return features;
}
