Insert new line in a backing bean string value

由 孤人 提交于 2020-02-02 10:06:50
问题 How to insert a new line between words for a backing bean value and display it on UI using JSF 2.0 framework? If we have address. The street name should be in first line and city and state should be in the second line. I am using a converter to add new line. But it does not show up on the UI. 回答1: JSF is basically a HTML code generator. A new line is in HTML to be presented by the <br /> tag, not by \r\n characters or something. You can just do it straight in the view instead of mingling view

Nesting variables in EL

由 送分小仙女□ 提交于 2020-01-28 11:23:09
问题 Is it possible to nest variable calls like below in EL using FacesContext or other implicit objects like request , session , etc.? This of course is not working. I get this error Error Parsing: #{myBean.myMethod(#{FacesContext.getCurrentInstance().getViewRoot().getViewId() })} for this attempt <ui:include src="#{myBean.myMethod(#{FacesContext.getCurrentInstance().getViewRoot().getViewId() })}"> 回答1: This is indeed invalid EL syntax. Nesting of #{} is disallowed. Just put the whole expression

The end result is to allow the user to configure the fields on the page through administrative functions. Below is a copy of the code that I am using as the test page where I loop through the "Configured" fields and write out the fields using the defined criteria. <ui:repeat var="field" value="#{eventMgmt.eventFields}" varStatus=

Skip required validation and invoke the application

由 无人久伴 提交于 2020-01-27 04:27:24
问题 I asked my question here but I think it lacks some obvious information. Hence I'm posting my question again. I have a JSF form which has some required validation on h:inputText fields. When submitting the form I want to skip(or ignore) the required validation check and still invoke the application. I do want to do the form data validation and show the errors based on some condition. Basically I want to skip the validations and invoke the application when the form is submitted using an ajax

Need tutorial on implementing a JSF ResourceHandler

由 社会主义新天地 提交于 2020-01-26 04:07:28
问题 My application needs to implement dynamic images, where a browse can get served a JPG or PNG out of my data base. I have been reading this thread and am not getting very far in learning from it. Can someone provide a link to a tutorial about how to implement a ResourceHandler. Having looked through all the books Amazon offers on JSF 2.0, none of them seem to cover this topic. Thanks in advance. UPDATE: This question is withdrawn since I took a different path to the solution, which was simply
