[richfaces-issues] [JBoss JIRA] (RF-12158) Autocomplete component re-renders panels with ajaxRendered=true at each character being typed in into the autocomplete box

[Lukáš Fryč (JIRA)]

    [ https://issues.jboss.org/browse/RF-12158?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12686978#comment-12686978 ] 

Lukáš Fryč commented on RF-12158:
---------------------------------

As Cristian said, {{rich:autocomplete}} was designed in RF4 to do not produce any side-effects with completion.

Any processing should be done using attached behaviors.

---

But...

[{{Autocomplete.js}}|https://github.com/richfaces/components/blob/develop/input/ui/src/main/resources/META-INF/resources/org.richfaces/Autocomplete.js#L189] shows that it is using {{RichFaces.ajax(...)}} to do the request, which causes the regular JSF AJAX request.

Then autocomplete's [{{RendereBase}}|https://github.com/richfaces/components/blob/develop/input/ui/src/main/java/org/richfaces/renderkit/AutocompleteRendererBase.java#L264] causes to hang this AJAX request prematurely when it identifies suggestion request.

But it isn't complete, since the ExtendedPartialViewContext will cause to add any {{ajaxRenderer}} components to the response.

The solution would be to instruct ExtendedPartialViewContext to do "{{limitRender}}" programatically.

This issue is similar to RF-9567.

> I tried to remove this: onkeypress="return submitOnEnter(event, '#{rich:clientId('qsPayorSupcdCmdBtnId')}')"
