                 Key: TRINIDAD-1837
                 URL: https://issues.apache.org/jira/browse/TRINIDAD-1837
             Project: MyFaces Trinidad
          Issue Type: Bug
          Components: Components
    Affects Versions: 1.2.13-core ,  1.2.12-core,  1.2.11-core, 1.2.10-core, 
1.2.14-core 
         Environment: WinXP, IE 8, Firefox 3.6, Tomcat 5.5
            Reporter: Volker Malzahn


If you want to update a textarea, i.e. a tr:inputText component with rows and 
columns set, in the response of a PPR request that doesn't function.

Reason: the JavaScript file Page.js has an error in function 
TrPage._getFirstElementWithId:
in line 503 the function calls itself recursivly, but it doesn't check if that 
call returns null or not:
    return TrPage._getFirstElementWithId(childNode);
If the first childNode doesn't contain the searched element the result will be 
null because the other children aren't checked.

Changing that line to
    var recCallResult = TrPage._getFirstElementWithId(childNode);
    if (recCallResult != null) {
        return recCallResult;
    }
solves the problem.
