[jira] Commented: (TRINIDAD-1171) A failing client-side validator while using PPR causes a page hang with hourglass in IE when clicking in a empty spot on the page

["Markus Krätzig (JIRA)" <de...@myfaces.apache.org>]

    [ https://issues.apache.org/jira/browse/TRINIDAD-1171?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12785944#action_12785944 ] 

Markus Krätzig commented on TRINIDAD-1171:
------------------------------------------

I guess the reason for the blocking is the following:

Taking off _doPprStartBlocking from the current thread via 

a0._pprTimeoutFunc=a0.setTimeout("_doPprStartBlocking(window);",1); 

in function _pprStartBlocking leads in function _submitPartialChange to the situation 
where 

_pprStartBlocking(window);
var a3=submitForm(a0,a1,a2,true);
_pprStopBlocking(window);

is not called in the order expected, instead, startBlocking is called after stopBlocking due
to the timeout. The only way to release the blocking is then via  _pprConsumeClick, for which the user 
must click outside the body area. 

The simplest  way to fix this is  to revert TRINIDAD-952. If the timeout should be kept in, then  
the threads must somehow be synchronized. But as far as I know there's not much provided by
javascript to do this.

I think fixing this issue should be prioritized, because it renders TRINIDAD pretty useless on all IE versions.

>             Project: MyFaces Trinidad
>          Issue Type: Bug
>          Components: Components
>    Affects Versions: 1.0.7-core,  1.0.8-core, 1.0.9-core
>         Environment: Windows IE6 and IE7
>            Reporter: Mark van den Boomen

>
> Code to reproduce:
> <tr:form id="testValidationForm">
>     <tr:inputDate value="#{test.myDate}" id="myDate" partialTriggers="validate">
>         <tr:convertDateTime pattern="dd-MM-yyyy" />
>     </tr:inputDate>
>     <tr:commandButton text="Validate" partialSubmit="true" id="validate" />
> </tr:form>
> Steps to reproduce:
>  1. fill in something in the date field so the (date) validation will fail (eg. "hello")
>  2. press "Validate"
>  3. Now click on a spot on the page (but within the body area)
> Now the hourglass shows in IE. The only way to get rid of it is to click outside the body of the page of on the toolbar of IE.
> I traced the problem back to bug TRINIDAD-952 whose fix is causing the problem, after reverting the change everything works ok in 1.0.8 .
