[jira] [Commented] (TRINIDAD-2431) trh:script with partialSubmit doesn't work correctly

["Maciej Jarkowski (JIRA)" <de...@myfaces.apache.org>]

    [ https://issues.apache.org/jira/browse/TRINIDAD-2431?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13835266#comment-13835266 ] 

Maciej Jarkowski commented on TRINIDAD-2431:
--------------------------------------------

Actually I did the workaround in my local jsf.js file: in the replaceHtmlItem, just before call to _Dom.outerHTML() I inserted:

			/* MJ */
			if( item.tagName=="SCRIPT" && markup=="") {
				//markup = item.outerHTML;
				markup = "<SCRIPT id=\"" + itemIdToReplace + "\">/*do nothing*/</SCRIPT>";
			}
			/* MJ */

So in fact, emptying the script element (described above, as the update element provided empty string) caused the next partialTrigger event to fail, as there were no item to update. So as a workaround I set markup to script element with any, no harming value.
Please note, this is only local workaround, not the final solution.

>             Project: MyFaces Trinidad
>          Issue Type: Bug
>          Components: Components
>    Affects Versions: 2.0.1-core
>         Environment: WebSphere Application Server 8.5 64bit on Windows 7, with MyFaces 2.0 support, trinidad-api-2.0.1.jar, trinidad-impl-2.0.1.jar, Internet Explorer 9, Quirks mode.
> The problem can be seen in Production or Development stage.
>            Reporter: Maciej Jarkowski
>            Priority: Critical
>   Original Estimate: 24h
>  Remaining Estimate: 24h
>
> On the JSF page we defined 
> xmlns:trh="http://myfaces.apache.org/trinidad/html"
> The page includes the following part:
> <trh:script partialTriggers="amountByClient " text="...some script here..."/>
> when partialTriggers occures I can see in the network monitor the following comes back to the browser:
> <?xml version="1.0"?>
> <partial-response>
>   <changes>
> 	<!-- some data here -->
> <!-- this is the data for my trh:script component - the ID matches with that on the IE HTML page ->
> <update id="j_id1850516215_5d7c425d">
>       <![CDATA[]]>
> </update>
>     <eval>
>       <![CDATA[...some script here - the same, as defined in the trh:script text attribute...]]>
> </eval>
>   </changes>
> </partial-response>
> So, I believe what JavaScript on the page is trying to do is replace the script with id 
> j_id1850516215_5d7c425d with empty string (that's not very good indeed, but shouldn't harm).
> Then it would "call" the part in <eval> tag. That's would be great - this is what we need.
> However, while the partial-response XML is processed it finaly comes to javax-faces/jsf.js, function outerHTML, which:
> 1. checks if the final markup is not empty/null -> which in fact is: see update element above.
> (actually it checks !markup, which evaluates to true if markup is empty string).
> 2. If it is null, it throws an exception, so no other processing is performed. Especially the eval part.
> 3. What's strange, if you check the outerHTML function code, if it passes step 1, it then replaces the original markup, but if and only if the final markup is not empty string.
> So I believe step 1 above is not really required, as it doesn't harm the method itself.
> Or maybe we should check if markup is not null, instead of !markup?
> We are just migrating from JSF 1.2 and can't finalize the migration because of this error.
> The scenario works correctly with the same JSF page on the older environment (JSF 1.2, trinidad 1.2), but reagarding partial submit I believe it is completely different story then.
