t:columns and findComponent
---------------------------
Key: TOMAHAWK-1105
URL: https://issues.apache.org/jira/browse/TOMAHAWK-1105
Project: MyFaces Tomahawk
Issue Type: Bug
Affects Versions: 1.1.6
Reporter: Daniel Herb
Hi,
i've written a phaseListener to replace the validation-errors with
custom-errors. To do this I've used "viewRoot.findComponent" to get the right
component for a clientId. It all worked fine till I've used it on a page with
the t:columns-tag. After some debugging I found out the following:
Assume that the id which we are searching looks like this:
mainBody:mainForm:mainTable:0:columns:0_0:componentId
The findComponent-method is called recursive:
mainBody:mainForm:mainTable:0:columns:0_0:componentId
- Search for Id "mainBody" => found
mainForm:mainTable:0:columns:0_0:componentId
- Search for Id "mainForm" => found
mainTable:0:columns:0_0:componentId
- Search for Id "mainTable" => found
- The following "0" is the rowindex of the component so the
findComponent-Method was overwritten by the HtmlDataTable to remove this also
from the id and use it as index.
- Returned is an object from the type "UIComponentPerspective" which points at
the correct row and delegate all methods to the child-component
columns:0_0:componentId
- Search for Id "columns" => found
- The following "0_0" is the row and column information which should be
replaced by an overwritten version of findComponent from HtmlColumns but there
is' no overwritten method.
0_0:componentId
- Search for Id "0_0" => not found!
- Because the columns-tag didn't removed the row and column information the
next recursive call is to find an id "0_0" which can't exists.
I think the findComponent-Method of HtmlColumns should work like that one from
dataTable and return an UIComponentPerspective-object
