NullPointerException after submitting modalpanel form
hi,
i am currently facing an strange component behavior and was wondering if somebody can help me out.
i have a modalpanel which gets called from within a form to change some values. After submitting of the form in the modalpanel the main table should rerender and show the changed results.
So one component in a form should force another component to rerender in a different form.
Everything works fine except of the rerendering at the end of the process (id="showOrders").
the exception is:
java.lang.NullPointerException org.richfaces.component.ColumnsSizeState.getColumnSize(ExtendedDataTableState.java:299) org.richfaces.component.ExtendedDataTableState.getColumnSize(ExtendedDataTableState.java:159) org.richfaces.component.UIExtendedDataTable.getColumnSize(UIExtendedDataTable.java:183) org.richfaces.renderkit.AbstractExtendedTableRenderer.encodeColumns(AbstractExtendedTableRenderer.java:130) org.richfaces.renderkit.html.ExtendedDataTableRenderer.doEncodeBegin(ExtendedDataTableRenderer.java:301) org.richfaces.renderkit.html.ExtendedDataTableRenderer.doEncodeBegin(ExtendedDataTableRenderer.java:236) org.ajax4jsf.renderkit.RendererBase.encodeBegin(RendererBase.java:101) org.richfaces.renderkit.AbstractExtendedTableRenderer.encodeBegin(AbstractExtendedTableRenderer.java:1346) javax.faces.component.UIComponentBase.encodeBegin(UIComponentBase.java:813) javax.faces.component.UIData.encodeBegin(UIData.java:962) org.ajax4jsf.component.UIDataAdaptor.encodeBegin(UIDataAdaptor.java:1220) com.sun.faces.renderkit.html_basic.HtmlBasicRenderer.encodeRecursive(HtmlBasicRenderer.java:232) com.sun.faces.renderkit.html_basic.GridRenderer.renderRow(GridRenderer.java:180) com.sun.faces.renderkit.html_basic.GridRenderer.encodeChildren(GridRenderer.java:127) javax.faces.component.UIComponentBase.encodeChildren(UIComponentBase.java:837) org.ajax4jsf.renderkit.RendererBase.renderChild(RendererBase.java:282) org.ajax4jsf.renderkit.AjaxChildrenRenderer.encodeAjaxComponent(AjaxChildrenRenderer.java:124) org.ajax4jsf.renderkit.AjaxChildrenRenderer.encodeAjaxChildren(AjaxChildrenRenderer.java:67) org.ajax4jsf.renderkit.AjaxChildrenRenderer.encodeAjaxComponent(AjaxChildrenRenderer.java:115) org.ajax4jsf.renderkit.AjaxChildrenRenderer.encodeAjaxChildren(AjaxChildrenRenderer.java:67) org.ajax4jsf.renderkit.AjaxChildrenRenderer.encodeAjaxComponent(AjaxChildrenRenderer.java:115) org.ajax4jsf.renderkit.AjaxChildrenRenderer.encodeAjaxChildren(AjaxChildrenRenderer.java:67) org.ajax4jsf.renderkit.AjaxChildrenRenderer.encodeAjaxComponent(AjaxChildrenRenderer.java:115) org.ajax4jsf.renderkit.AjaxContainerRenderer.encodeAjax(AjaxContainerRenderer.java:123) org.ajax4jsf.component.AjaxViewRoot.encodeAjax(AjaxViewRoot.java:677) org.ajax4jsf.component.AjaxViewRoot.encodeChildren(AjaxViewRoot.java:548) javax.faces.component.UIComponent.encodeAll(UIComponent.java:930) com.sun.faces.application.ViewHandlerImpl.doRenderView(ViewHandlerImpl.java:266) com.sun.faces.application.ViewHandlerImpl.renderView(ViewHandlerImpl.java:197) org.ajax4jsf.application.ViewHandlerWrapper.renderView(ViewHandlerWrapper.java:100) org.ajax4jsf.application.AjaxViewHandler.renderView(AjaxViewHandler.java:197) com.sun.faces.lifecycle.RenderResponsePhase.execute(RenderResponsePhase.java:110) com.sun.faces.lifecycle.Phase.doPhase(Phase.java:100) com.sun.faces.lifecycle.LifecycleImpl.render(LifecycleImpl.java:139) javax.faces.webapp.FacesServlet.service(FacesServlet.java:266) org.ajax4jsf.webapp.BaseXMLFilter.doXmlFilter(BaseXMLFilter.java:178) org.ajax4jsf.webapp.BaseFilter.handleRequest(BaseFilter.java:307) org.ajax4jsf.webapp.BaseFilter.processUploadsAndHandleRequest(BaseFilter.java:423) org.ajax4jsf.webapp.BaseFilter.doFilter(BaseFilter.java:550)
