jsf - Is conditional rendering of components possible inside datatable without updating the entire datatable? -

<h:datatable value="#{bean.listofrows}" var="eachrow" id="thedatatable"> <h:column> <p:outputpanel rendered="#{eachrow.visible}"> <h:selectmanycheckbox value="#{xxxx}" label="#{xxxx}"> <f:selectitems value="#{checkboxitems}" var="eachitem" itemlabel="#{eachitem.label}" itemvalue="#{eachitem.value}" /> <p:ajax event="change" update="thedatatable" /> </h:selectmanycheckbox> </p:outputpanel> <p:outputpanel rendered="#{eachrow.visible}"> <h:selectoneradio value="#{xxxx}" label="#{xxxx}"> <f:selectitems value="#{radioitems}" var="eachitem" itemlabel="#{eachitem.label}" itemvalue="#{eachitem.value}" /> <p:ajax event="change" update="thedatatable" /> </h:selectoneradio> </p:outputpanel> <p:outputpanel rendered="#{eachrow.visible}"> </p:outputpanel> <p:outputpanel rendered="#{eachrow.visible}"> </p:outputpanel> <p:outputpanel rendered="#{eachrow.visible}"> </p:outputpanel> <p:outputpanel rendered="#{eachrow.visible}"> </p:outputpanel> . . . </h:column> </h:datatable>

within set of rows of info table, rows conditionally rendered depending on value alter events(processed using ajax requests) on previous row's input component. can create these rows visible without re-rendering entire info table ? ? ? using jsf 2.0.6 primefaces 2.2.1.

as suggested balusc question link utilize padding in datatable column this.

<h:datatable id="maindatatable" value="#{bean.listofrows}" var="eachrow" id="thedatatable"> <h:column> <h:panelgroup id="padding" layout="block"> <p:outputpanel rendered="#{eachrow.visible}"> <h:selectmanycheckbox value="#{xxxx}" label="#{xxxx}"> <f:selectitems value="#{checkboxitems}" var="eachitem" itemlabel="#{eachitem.label}" itemvalue="#{eachitem.value}" /> <p:ajax event="change" update="thedatatable" /> </h:selectmanycheckbox> </p:outputpanel> <p:outputpanel rendered="#{eachrow.visible}"> <h:selectoneradio value="#{xxxx}" label="#{xxxx}"> <f:selectitems value="#{radioitems}" var="eachitem" itemlabel="#{eachitem.label}" itemvalue="#{eachitem.value}" /> <p:ajax event="change" update="thedatatable" /> </h:selectoneradio> </p:outputpanel> <p:outputpanel rendered="#{eachrow.visible}"> </p:outputpanel> <p:outputpanel rendered="#{eachrow.visible}"> </p:outputpanel> <p:outputpanel rendered="#{eachrow.visible}"> </p:outputpanel> <p:outputpanel rendered="#{eachrow.visible}"> </p:outputpanel> . . . </h:panelgroup> </h:column> </h:datatable>

the datatable creates padding on every component in column whether rendered or not. upto dependent logic. if want update particular row of datatable utilize client id generated backing bean or binding component bean suggested balusc in question. client id of format maindatatable:rowindex:padding. cheers!

How do I check if an insert was successful with MySQLdb in Python? - i have code: cursor = conn.cursor() cursor.execute(("insert new_files (videos_id, filename, " "is_processing) values (%s,%s,1)"), (id, filename)) logging.warn("%d", cursor.rowcount) if (cursor.rowcount == 1): logging.info("inserted values %d, %s", id, filename) else: logging.warn("failed insert values %d, %s", id, filename) cursor.close() fun is, cursor.rowcount always one, though updated database create videos_id unique key. is, insert fails because in tests same videos_id going appear (and when check database, nil inserted). whatever reason, rowcount 1 - logging.warn have spits out rowcount of 1. so, question: can utilize rowcount work out if insert went fine? if so, (presumably) doing wrong? otherwise, how check if insert went fine? your code not commit after modifications (your modifications rolled back). should...
