Delay ajax request from rich toolTip

[six-p4ck]

Hello all.

I have a little question for a specific problem with a richfaces component.

I have a overflow of sql request when i do this:



i use this code:

<rich:column>
 <f:facet name="header">
 <h:outputText value="#{messages['user.header.preview']}" />
 </f:facet>
 <a4j:mediaOutput element="img" rendered="#{_user.userImage != null ? 'true' : 'false'}" style="width:20px; height:20px;" mimeType="#{_user.userImage.contentType}" createContent="#{userPaint.paint}" value="#{_user.userImage.id}" cacheable="false">
 <f:param value="#{userList.timeStamp}" name="time" />
 <rich:toolTip showDelay="500" mode="ajax">
 <span style="white-space: nowrap">
 <a4j:mediaOutput element="img" rendered="#{_user.userImage != null ? 'true' : 'false'}" mimeType="#{_user.userImage.contentType}" createContent="#{userPaint.paint}" value="#{_user.userImage.id}" cacheable="false">
 <f:param value="#{userList.timeStamp}" name="time" />
 </a4j:mediaOutput>
 </span>
 </rich:toolTip>
 </a4j:mediaOutput>
 <h:graphicImage rendered="#{_user.userImage != null ? 'false' : 'true'}" style="width:20px; height:20px;" alt="no preview" url="/img/no_preview.gif" />
</rich:column>

I have delay for show the image, thats good but not for the ajax-request

Then when i do fast up and down many time on the image list i have a lot of useless ajax request who generated SQL request.

If i have a few user who make this in same time, my DB come very slow... too much request

is it possible to make a delay for the ajax request? My delay work only for the show actually. And i can make a onclick because next step is show in a modal when you click on the picture

thx all.

Hello,

showDelay affects AJAX requests too. I see difference in behavior with showDelay="0" and showDelay="500". In fact, AJAX request is fired only when tooltip is first shown.

Ok it's another problem:

when i add

mode="ajax"

delay stop working...

Then this work fine, i have delay but page is slow because he preload all picture

<rich:toolTip showDelay="2000">
 <span style="white-space: nowrap">
 <a4j:mediaOutput element="img" rendered="#{_annex.image != null ? 'true' : 'false'}" mimeType="#{_annex.image.contentType}" createContent="#{annexPaint.paint}" value="#{_annex.image.id}" cacheable="false">
 <f:param value="#{annexPaint.timeStamp}" name="time" />
 </a4j:mediaOutput>
 </span>
</rich:toolTip>

And the same with :

<rich:toolTip showDelay="2000" mode="ajax">

I have ajax request, the load of the page is faster, but i lose the delay for display the tooltip...

Any idea?

thx

showDelay works for me either with "ajax" (delaying request) or "client" modes. I've tried with RF 3.3.0.GA version.

Ok i have change the richfaces library from SEAM 2.1.1.GA who use richfaces 3.2.2.SR1 to 3.3.0GA and now it's work fine.

Thx

in Richfaces4 the ajax request is sent instantly and the toolTip is showed only afterwards. How can i change this?

Thanks.
