Hi everybody,

I am trying to set a custom variant on Grid as describes in the developers guide.
The requirement is to change the selection color dynamically according to the domain context.

Here is the CSS I use:
Tree-RowOverlay.source-selection:selected,
Tree-RowOverlay.source-selection:selected:unfocused,
Tree-RowOverlay.source-selection:linesvisible:even:selected,
Tree-RowOverlay.source-selection:linesvisible:even:selected:unfocused {
  background-color: rgb(203, 1, 79);
  color: rgb(0, 0, 0);
}

Tree-RowOverlay.link-selection:selected,
Tree-RowOverlay.link-selection:selected:unfocused,
Tree-RowOverlay.link-selection:linesvisible:even:selected,
Tree-RowOverlay.link-selection:linesvisible:even:selected:unfocused {
  background-color: rgb(17, 62, 157);
  color: rgb(0, 0, 0);
}


Setting an initial variant doesn't change anything:
grid.setData(RWT.CUSTOM_VARIANT, "source-selection");


Any further attempt to set the SAME variant has no effect either:
grid.setData(RWT.CUSTOM_VARIANT, "source-selection");


Any further attempt to set a DIFFERENT variant throws a client error in the browser:
grid.setData(RWT.CUSTOM_VARIANT, "link-selection");

results in:
Client Error

Error: Error: Operation "set" on target "w56" of type "rwt.widgets.Grid" failed:

Properties: 
customVariant = variant_link-selection
selection = w181,w182,w183,w184

Hi,

which RAP version are you using? Please open a bugzilla and provide a snippet/project (with the custom CSS file) to reproduce the issue.
Could be related to:
551447: Table linesVisible JS exception if any column width is zero

Best regards,
Ivan

Hi Ivan,

you are right!
I am affected of 551447 because my Grid has an initially collapsed GridColumnGroup.

I can confirm that the problem is solved by the fix of 551447. I tested it with build rap-e4-nightly-3.11.0-S-20191105-0036.

By the way there are 2 points to improve:
1. The development guide states that 'Grid uses the theming of Tree' which can be misunderstood to use Tree-RowOverlay.* instead of Grid-RowOverlay.* in css. I suggest to add an explaining sentence wich mentions 'Grid-RowOverlay'.

2. The nightly build rap-e4-nightly-3.11.0-S-20191105-0036 is missing the bundle org.eclipse.equinox.util which is needed for a self contained target platform.

Thank you
Sebastian
