Wolfgang Schwendt commented on JBSEAM-2697:
-------------------------------------------

The shortened link of course would be
http://127.0.0.1:8080/seminaris/seminarDetails.seam?seminarId=2    

(not "semId" as parameter), 

but I think the idea can be understood.

> When an s:link component (org.jboss.seam.ui.component.UILink) is placed into a h:dataTable backed by a javax.faces.model.DataModel,  the s:link automatically generates the magic token for the magic "dataModelSelection" parameter regardless of whether the latter is really needed or not.
>  
> This can generate ugly URLs.    The following example is particulary ugly:
> http://127.0.0.1:8080/seminaris/seminarDetails.seam?seminarId=2&dataModelSelection=sem%3AzumSeminarAnmelden_szSeminarSuchen_seminarListeDataModel%5B1%5D&actionMethod=zumSeminarAnmelden%2FseminarSuchen.xhtml%3AzumSeminarAnmelden_seminarBuchenAction.selectSeminar
> Without the "dataModelSelection" parameter, the URL would look much cleaner:
> http://127.0.0.1:8080/seminaris/seminarDetails.seam?semId=2
> So my question:   Couldn't we make the "dataModelSelection" parameter optional? (For example, by adding an attribute to the s:link tag).
> Btw:  I'm aware that  org.jboss.seam.ui.component.UISeamCommandBase.getUrl() is the culprit that triggers inclusion of the the dataModelSelection parameter, so I know how to remove the dataModelSelection parameter generation, but it would be nice if also the officially released Seam version allowed the deactivation of the magic token generation.
> Further, no magic token is generated if a UIDataTable is supplied by a normal List rather than a DataModel (cf. UISeamCommandBase.getSelection() ), but unfortunately there can be cases where it makes sense to supply the table data as DataModel rather than normal List.
