View Full Version : [FIXED] [2.0 Trunk]: column.setHidden(true) is ignored when rendering a grid

27 May 2009, 1:33 AM
Hi Dev-Team,

after synchronizing the current trunk this morning (rev 1492) the column.setHidden(true); is ignored while opening a grid. The gridheader displays also the hidden columns. The content is displayed correctly.

You can test this issue when modifying the GridExample from the explorer and add the line column.setHidden(true); after line 62. After that the header of the "Company" column remain displayed.

+1 for this.

This originally posted error is solved with Rev. 1507. Unfortunately I get the following error in the same testcase, when I want to open the context-menu for the last column.

That works fine for me. Can you please post some testcase that is demonstrating this issue? I also dont have this on the examples.

As on the original problem you can test this when modifying "Basic-Grid" Example (com.extjs.gxt.samples.client.examples.grid.GridExample) from the explorer and add the line column.setHidden(true); after line 62. Now "Company" is not shown, but if you try to open the context-menu of the last column ("Last Updated") the mentioned error occurs.

Its the same behaviour as on


if you hide "Company" and then open the context-menu of "Symbol" the context-menu of "Last" is opened.

Ok, thanks for reporting that. We changed the Header a lot to support a few (better a lot) more features.

Fixed in SVN
