Add the ability to the show* components to always get their disclosed property
from EL
--------------------------------------------------------------------------------------
Key: TRINIDAD-886
URL: https://issues.apache.org/jira/browse/TRINIDAD-886
Project: MyFaces Trinidad
Issue Type: New Feature
Components: Components
Affects Versions: 1.0.5-core, 1.2.5-core
Reporter: Andrew Robinson
Assignee: Andrew Robinson
Priority: Minor
The disclosed property of showDetail components are updated by the renderers.
It would be extremely helpful to stop this behavior so that EL is always used.
Example of someone wanting to disclose only one item:
public class Bean {
private int disclosedIndex = -1;
public void handleDisclose(DisclosureEvent event) {
// manually update the index
}
...
}
<tr:iterator var="_item" value="#{bean.items}" varStatus="_varStatus">
<tr:showDetail disclosedText="#{_item.title}"
undisclosedText="#{_item.title}":
disclosed="#{bean.disclosedItem eq _varStatus.index}"
disclosureListener="#{bean.handleDisclose}">
<af:outputFormatted value="#{_item.desc}"/>
</af:showDetail>
</af:iterator>
Proposal:
A new attribute to be added to showDetial* components:
public boolean isDisclosedTransient() {}
This should default to false. If set, the renderer should never set the
disclosed property locally, or the faces bean property value should ignore
sets. This way the disclosed property set in the UI would always be used to
determine disclosed state.
