Is there a way to find out the button click if a onchange is triggered

Question

I have two date fields (from / to) that render the whole creatingPanel (id="createPanel") with for Example ratiobuttons(id="wiederholungsSelect") for (monthly, daily, weekly, none) depending on date range. If the "from" or "to"-date is changed the possibility for selection a ratiobutton should be updated. And if everything is filled out the user clicks a commandButton to save it.

So what happens in practice?

The User types in the from (id="gueltigAb") and to(id="gueltigBis") date and then directly clicks on the commandbutton (id="newSave"). But the click is only to trigger the onchange event of the ajax and not to trigger the button. The User now have to click the button a secound time which is very anoying.

What has been tested?

I tested although:

• <f:ajax event="change" execute="@this" render="form:createPanel" />
• <f:ajax event="valueChange" execute="@this" render="form:createPanel" />
• <f:ajax event="blur" execute="@this" render="form:createPanel" />
• <f:ajax event="change" execute="form:createPanel" render="form:createPanel" />

Is there a way to trigger the onchange and the clicked button?
