| <h2>Talking points for the discussion</h2> |
| <p> |
| Purpose: To allow JSF-specific content assist to be hosted |
| in relevant attribute value within the JSP editor. |
| <br></br> |
| The bug <a class="external" href= "https://bugs.eclipse.org/bugs/show_bug.cgi?id=130041" > 130041</a> |
| logs the proposed change request to support content |
| assist for JSF EL in the JSP editor including a patch for |
| the existing configuration. Proposal: |
| </p> |
| <p> |
| Summary: <br></br> |
| 1) For expression language (EL) attribute values (those of |
| the form "#{...}"), a patch would be applied to |
| StructuredTextViewerConfigurationJSP.getContentAssistProcessors |
| that handles the currently unhandled case for the partition |
| IJSPPartitions.JSP_DEFAULT_EL2. This new logic would call |
| into a new class called ContentAssistantProcessorLocator. |
| This new class would use a new extension point (or |
| alternatively a new provisional element of the |
| editorConfiguration extension) to find all |
| ContentAssistProcessors that wish to contribute to |
| content-assist for late-bound (JSF) EL attribute values. JSF |
| content assist would use this extension point to contribute |
| it's logic. The impact to existing logic is almost nil. All |
| new logic will be provided by JSF team as part of the patch. |
| </p> |
| <p> |
| NOTE: this scheme could extended in the future to support |
| content assist contributors for other partition type as |
| well. Most of the delta would be localized to the same |
| configuration method. |
| </p> |
| <p> |
| 2) For non-EL attributes the existing Model Query extension |
| point would be used. While this is not a public interface, |
| it was the only way found that content assist could provided |
| unobtrusively for partitions not already handled by the JSP |
| editor configuration. |
| </p> |
| <p> |
| An alternative would be to add similar extension point |
| support as discussed in 1), but add it for partition types |
| already handled. Again, JSF team would provide all new logic |
| required in this area. |
