Re-opened.

We seem to be going in circles on this issue...

Due to the inherent complexities of this component we will drop support for using the clientValidator* "validateOn" attribute with it. It will continue to function with client validators using the default submit events as it has previously.

Well, I gave it another shot and I believe I got it right this time. In order to make the client validation work as expected I had to enhance client validation to respect the scope of the 'execute' attribute of a partial submit.

So, for (2) where validation is triggered by the partial submit we need to define which components are executed (client validation will now respect that):

<ace:autoCompleteEntry id="autoCompleteEntry1" value="#{autoCompleteEntryClientVal.value1}"
                                        rows="10" label="ace:autoCompleteEntry 1" labelPosition="top">             
                 <ace:clientValidateRequired  />      
                 <ace:ajax execute="@this" render="@this messageGrid1" event="blur"/>         
                <f:selectItems value="#{autoCompleteEntryBean.cities}"/>
</ace:autoCompleteEntry>

The event "blur" needs to be defined on the ace:ajax facet since the default behviour for required validation is to enforce it only when the form is submitted. See https://jqueryvalidation.org/required-method/ .

Here there are 3 autoCompleteEntries in a form, set up as suggested in your last comment in ICE-11132.

<ace:autoCompleteEntry id="autoCompleteEntry1" value="#{autoCompleteEntryClientVal.value1}"
                                        rows="10" label="ace:autoCompleteEntry 1" labelPosition="top">             
                 <ace:clientValidateRequired  />      
                 <ace:ajax execute="@this" render="@this messageGrid1" event="blur"/>         
                <f:selectItems value="#{autoCompleteEntryBean.cities}"/>
</ace:autoCompleteEntry>

The first autoCompleteEntry validates as expected but the other two do not. No messages are shown for autoCompleteEntries 2 and 3 unless a submit via submit button is performed."

Fixed disableRules function to return the disabled rules for the current submit (as it's expected from it).
