viewFile doesn't work anymore

[daviddb]

With the nightly build of 09/19/2010, the viewFile functionality doesn't work anymore in our application. (clicking on the magnify glass in the listgrid)

We get the following error:

DsResponse.getData().get("attm_file") returned an instance of java.io.ByteArrayInputStream when we were expecting an InputStream.

The attm_file column is a BLOB column in a mysql database (datasource is of servertype SQL)

this is the datasource:

                VLayout layout = new VLayout();
		layout.setHeight100();
		layout.setWidth100();
		
		ListGrid grid = new ListGrid();
		grid.setDataSource(DataSource.get("Attachment"));
		grid.setAutoFetchData(true);
		
		layout.addMember(grid);
		
		layout.draw();

This worked fine with the nightly build of last week

I have updated this issue to give more detailed information on how to reproduce.

[daviddb]

Sorry for updating this issue again but we did some more research on this (because it is a really blocking issue, none of the blobs in our databases can be opened or downloaded anymore)

We more precisely investigated when it went wrong and we found out that in the nightly builds of smartgwt 2.3 power edition:

- it worked in the build of september 5th and before
- it does not work in the build of september 14th and after

(we did not download every build but this should hopefully give you some information)

(and we need the nightly build of september 19th because of other issues that were fixed in it)

[Isomorphic]

This was an unfortunate side effect of trying to accept more data formats for streaming and has been fixed - grab the next nightly.

[daviddb]

The last nightly poweredtion build I see is from 2010-09-20, I guess that is not the one with the fix?
Any idea why there is no 2010-09-21 build?
