Primefaces enter key closes dialog - primefaces

Question

When the below dialog is opened and the user hits enter it closes. I'm assuming that I need to somehow add some attribute to the below commandButton to not allow it to submit when the user hits enter. Any idea?
<p:dialog header="#{bundle['dreamSearch.HEADER']}"
widgetVar="webSearchDlg" modal="true" styleClass="dialog dialog2"
draggable="false" resizable="false" showEffect="fade"
hideEffect="fade">
<h:form id="dreamWebSearchFrm">
<div class="dialog-top-reg"></div>
<div class="dialog-middle-reg">
<div><p:commandButton styleClass="close zoom3" onclick="webSearchDlg.hide()" /></div>
<div class="dialog-content dialog-content2">
<h1 class="dream-search">
<h:outputText value="#{bundle['dreamSearch.HEADER']}" />
</h1>
<p class="dream-search">
<h:outputText value="#{bundle['dreamSearch.SUBHEADER']}" />
</p>
<p:panel id="searchTextPnl">
<div class="dream-search-wrap">
<fieldset>
<p:inputText id="searchText" value="#{dreamSearchBean.searchText}"/>
<p:commandButton tabindex="-1" styleClass="form-btn1" value="#{bundle['dreamSearch.search.button.TEXT']}"
actionListener="#{dreamSearch.search}" update=":dreamWebSearchFrm:resultsPnl"/>
</fieldset>
</div>
</p:panel>
<p:panel id="resultsPnl">
<div class="data-grid-wrap">
<h:outputFormat escape="false" value="#{bundle['dreamSearch.imageResults.TEXT']}" rendered="#{dreamSearchBean.shouldRender}">
<f:param value="#{dreamSearchBean.searchText}" />
</h:outputFormat>
<p:dataGrid var="dream" value="#{dreamSearchBean.dreams}" rendered="#{dreamSearchBean.shouldRender}" columns="5"
rows="10" paginator="true" effect="true"
styleClass="ui-header-visibility"
paginatorTemplate="{CurrentPageReport} {FirstPageLink} {PreviousPageLink} {PageLinks} {NextPageLink} {LastPageLink} {RowsPerPageDropdown}"
rowsPerPageTemplate="10,15,20" paginatorPosition="bottom">
<p:column>
<h:panelGrid columns="1" style="width:100%">
<p:commandLink onclick="webSearchDlg.hide();dreamEditDlg.show();" update=":dreamEditFrm:display">
<f:setPropertyActionListener value="#{dream}" target="#{dreamModifyBean.selectedDream}"/>
<f:setPropertyActionListener value="false" target="#{dreamModifyBean.editLink}"/>
<p:graphicImage value="#{dream.imageThumb}" width="100" height="100" />
</p:commandLink>
</h:panelGrid>
</p:column>
</p:dataGrid>
</div>
</p:panel>
</div>
</div>
<div class="dialog-bottom-reg"></div>
</h:form>
</p:dialog>

Answer 1

You could do it with Javascript. A similiar question with a variety of answers has been asked some time ago.
Primefaces has it's own (or some adapted JQuery / YUI) javascript bundled. Don't know how it interacts with self-made js. Give it a try!

Answer 2

In order to solve this, I had to ensure that the close button was the very last button within the form.
