Salient Soft

I had an Eclipse Galileo workspace containing several projects, and for some reason some of the projects did not show a full palette of components when opening a jspx file using the Web Page Editor. The main culprit was the ICEfaces components set which was missing. The workspace as a whole was clearly OK, but some projects had become broken. I now believe that some changes I made to user library locations may have caused the problem, but not sure on this.

Firstly, I visited the JSF project facets screen by right clicking the project in the explorer and selecting Properties to open the project properties page, then opening the  Project Facets entry in the left hand pane. I removed (unticked) support for ICEfaces and saved the changes. Then I added it back and saved again. This did not fix the problem.

I looked at the JSF Tag Registry view which lists all the Tag libraries registered for a project. This can be displayed by clicking menu option Window/Show View/Other and then entering Tag in the search box at the top. Select Tag Registry under JSF and the view will open. You must select the desired project in the view as it does not default to the current project. You can then expand the entries to see the Tag libraries registered. If you select one of the top level nodes on the registry tree (in my case these were labelled Facelet Tag Registry and JSP Tag registry) you can click the refresh button adjacent to the project selection button. This refreshes the entries, and you can elect whether or not to flush the cache in the resulting dialog. Unfortunately it was of no help to me in fixing the above problem, and refreshing/clearing the cache did not clear the issue. However, this view could be useful to browse Tag Library registrations.

I was aware that the palette entries are driven by the available Tag libraries on the project Build path, so still felt that it was library related. I then revisited the project properties page, and this time expanded the Project Facets entry in the left pane rather than clicking on it. I then selected Java Server Faces. This listed the user libraries for the project in the right hand pane, including all of the ICEfaces and JSF ones. I deselected all but one of them (you cannot deselect all of them), leaving the JSF 1.2 (Sun RI) library selected. I then applied/saved the changes and closed the screen. I then re-opened it, selected all the originally selected libraries and applied/saved again. This time, when I opened a jspx file in the project with the Web Page Editor, the ICEfaces components were present on the palette.

One last glitch was that after doing this, the palette entries for ICEfaces only had icons present, no descriptions. I then  closed the web page editor window, and closed Eclipse down normally, and re-opened the same workspace in Eclipse again. I then re-opened the same jspx in the Web Page Editor, and this time the ICEfaces components were all present with both the Icons and the descriptions. Problem solved!
