Filter Facet is not working in Richface 4.3x

由 ≯℡__Kan透↙ 提交于 2019-12-12 02:48:50
问题 In the Code below, You can observe two things: 1) Default sorting is getting utilized. 2) Image based custom filter is used. Problem I am facing : When I click on filter image default sorting is getting triggered. Need a way by which If I click on filter, default sorting doesn't get triggered. (This was achieved in Richface 3.3 by putting this custom filter in filter facet.) Any help or hint would be greatly appreciated. <rich:column sortBy="#{model.modVal}" label="Model Value" sortable="true

JSF 2: possible to initialize session-scoped beans on session start?

由 99封情书 提交于 2019-12-12 02:45:01
问题 Is it possible in JSF 2 to initialize a session-scoped managed bean as soon as the session context is loaded? I know it's possible with Application Scoped beans and the eager attribute in the @ManagedBean annotation, but does something similar exist for session beans? I have a session-scoped bean that I want to have loaded regardless of if a specific page is visited. 回答1: Are you sure you need a bean? If it is some general initialization stuff, you can use a HttpSessionListener , and on

Change input based on combo value

由 烈酒焚心 提交于 2019-12-12 02:43:08
问题 I know this question exists somewhere else in SO but either the solutions are old (and JSF seems to have improved a lot) or I cannot make the solution work. As simple as it sounds, I would like to replace the text of an input element based on the value of a combo box. I would like to use Ajax, and would like this to work even if there is only one element in the combo (it doesn't matter if by default the selection of the combo is empty). <h:selectOneMenu id="fnamecombo" valueChangeListener="#

Bean properties not being updated

由 点点圈 提交于 2019-12-12 02:29:25
问题 My bean is viewscoped. I have a simple string property with a getter and setter. The getter works fine(checked by initialising the property), but not the setter. In the setter method I am building a Stringbuffer using each of the incoming parameter. Code: public String getParamval() { return paramval; } public void setParamval(String paramval) { logger.info("Incoming value:" + paramval); pvals.append(paramval); this.paramval = "VAL"; } Is that wrong? I have tested within the setter to see if
