How do i get a refernce to the exception thrown in my jsp page
I have defined a global exception handler which logs the exception and then foreards to my error page. In the error page I need to get a reference to the exception but there is no exception object. How do i get a reference to the exception thrown in the jsp page? thanks - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Bug in tile with struts 1.1
My layout file (layout.jsp) has the following block tiles:insert attribute=header flush=true/ tiles:insert attribute=menubar flush=true/ tiles:insert attribute=body flush=true/ That is I want first the header tile to be layed out, then the menu tile and finally the body tile. The definition for the page in the tiles-def.xml file is definition name=.customer.page path=/WEB-INF/layout.jsp put name=header value=/WEB-INF/header.jsp / put name=menu value=.menu / put name=body value=/WEB-INF/customer.jsp / /definition definition name=.menu path= controllerUrl=/admin/menu.do /definition definition name=.menubar1 path=/WEB-INF/menu.jsp putList name=menu item value=Search link=/admin/search.do classtype=org.apache.struts.tiles.beans.SimpleMenuItem tooltip=Search for customers / /definition Note that the menu uses an action to determine whether the current logged on user should have access to this item. In fact I have several menubars and the action forwards tot he relevant one for the user. the struts-config mapping is action path=/admin/menu type=com.CheckRoleAction forward name=success path=.menubar1/ forward name=failure path=.error/ /action Now all this works perfectly EXCEPT that the order of the tiles is wrong. The menu tile is displayed before the header tile. If i change my layout to tiles:insert attribute=header flush=true/ tiles:insert attribute=body flush=true/ tiles:insert attribute=menubar flush=true/ then everything works Ok. This is only a problem when using a tiles controller and I am sure it was working correctly in struts 1.0 ( in fact i am certain it was ok even in the 1.1 betas) I was going to raise this in the bug database if everything here is OK thanks - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Might be as well a bug in a (most probably newer) version of your Tomcat/Whatever.. I just wonder, because easily spotted bugs like this one should already have shown up by long time.. Cheers, Yann I am using and have been using tomcat 4.1.24 so this is definitely new behavior from tiles. when I try out builds before struts 1.1 final this does not occur. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
on using beans in different scopes
I have a number of beans set in the application scope that I want to use in various select boxes. The docs say to use html:options collection=bean where bean is the bean in some scope. However when I try this I get an exception no bean specified eventhough I can show that the required bean is available in the application scope. what am i missing here? there is no scope field in the html:options tag to let it know where to look for the bean... thanks - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Problem with tiles in struts rc2
The following tiles insert tiles:insert attribute=header / tiles:insert attribute=menubar/ now places the menubar above the header. Nothing i dio changes this and the behaviour was correct in RC1. Note that my menubar definition uses a ControllerUrl. bye - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: tiles and tiles controllers
Currently i have two page definitions - one for inheritence and one for the controller. The controller is a TilesAction - I suppose i could create a TilesAction that did nothing and have the inherited pages use that but it seems an unnecessary hack. It would be good if setting the controllerUrl to was OK or even a switch to disable it.

dealing with null values
I need to write out beans that can have complex nested object that may sometimes be null. If they are null i would like nothing to be output. Is there a way to do this with struts without having to check if a property exists every time? thanks - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

confused about an action forms fields
Do all the fields of an actionform have to be strings? I am confused as to when a form field should become an entity in my business logic. For example, I have quite complex business objects composed of ArrayLists, Dates and other classes. How are these to be set? Do I need to capture everything as a primitive type and then have my action build the complex business entity? if I am updating an already existing entitiy do I need to change every field in it manually? thanks - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: confused about an action forms fields
Nicolas De Loof wrote: As user can edit them, you should set all actionform fields as string. You can use Collection, arrays and references to obects with String fields. This way you can build a formbean model that has the same look as your business object model (or data transfert objects). You can the use BeanUtil.copyProperties() to populate DTO datas to a formbean and afert user edited it (and validation occured)transfert formbean datas to DTO back. FormBean are this way a String-copy of your business, that user can edit. BeanUtil will convert data types (you can register converters if needed) Nico. Am i right in that BeanUtil can only copy basic data types and not complex data types that i have created myself? Presumably if I have a form that allows changing a user's role ( which is of type Role ) i need to compare the string roleName returned by the form with a cache of possible role objects and if one exists with that name assign it to the user manually.

Are action forms reused?
I am using struts 1.1. What I would like to know is whether a new form bean is created in the following situation: An action sets a form bean as an attribute and passes it for display to the appropriate jsp page and its contents displayed. This form is updated and submitted to a different action. Now, is the form bean that submitted the second time the same as the first form or has a new form bean been created and its fields re-populated. thanks - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

wrapping beans in a form - any ideas
Have there been any discussion on the pros/cons of having forms like
class MyForm extends ActionForm {
MyBean bean;
public void setBean(MyBean bean) {
this.bean=bean;
}
public MyBean getBean() {
return bean;
}
}
And then use the properties like so bean:write name=bean
property=bean.name / and so on
cheers
