[TRINIDAD]Tree table does not show correct bindings.
----------------------------------------------------
Key: TRINIDAD-1165
URL: https://issues.apache.org/jira/browse/TRINIDAD-1165
Project: MyFaces Trinidad
Issue Type: Improvement
Components: Components
Affects Versions: 1.2.8-core
Environment: Apache Trinidad 1.2.8, Jboss 4.2.1-GA
Reporter: Dushyant Agarwal
Fix For: 1.2.8-core
Hi,
I have a JSF page,that contains a tree table that shows data arriving from
database via EJB.
The number columns of the tree table is dynamic. They get created at the time
the page is just about to be rendered at the After render response phase
event.
Now the <nodeStamp >facet of the tree table contains a column containing
inputText whose readInly has been st as true in the jsp. Rest of the columns
get created dynamically. These other columns contain editable inputTexts.
Their programmatically provided value binding using the setValueExpression()
method of CoreInputText class.
Now there is a radio button in the page whose auto submit is set to true. The
valueChange Listener method attached to it does the following:
1.Delete all the columns of tree table: using the following code
for(int i=0i<treeTable.getChildren.size();i++){
i=-1;
treeTable.getChildren.remove(treeTable.getChildren.size()-1;
}
2. Calls a method on the EJB to get a list of objects from the Database. Based
on this new columns are instantiated,new inputTexts are created,Their
valueBindings are provided and added to the columns. Then the columns are added
to the table.
Now on changing the value of the radio buttons I talked about earlier, the
value of the tree tables columns does get changed. But the value of the column
in the nodeStamp facet also changes. On debugging I found that the value
binding of that column's inputTexts had become equal to the last column's
inputTexts'binding that appeared in the previous view.i.e.the view that had
appeared before clicking on the radio button.
I tried removing the jsp code of node stamp and then creating it afresh from
the backing bean.This included removing the children of the node stamp column
every time.
But I just could not get the valueBinding right.
Now is there any explanation as to how the columns should be removed so that
the value bindings also get removed safely. Where can I make changes to secure
the error?
Thanks,
Dushyant
