Hello, this is tested with HMI 4.11.1 and 4.11.5. If there is a Grid control with 0 displayed rows, and this grid control was not shown on the view, then leaving that view will throw an error each second time. The error you can see in the log below. This happens to me in one of my objects. It has a view which contains a tab control. In one of those tabs there is a grid control. In the default case this grid control will be empty, that is the number of visible rows is linked to a variable containing 0. Only in some cases there will be data to display in there. The problem is that this tab is also not the default tab that gets shown when the view is opened. So the grid control is hidden by default and empty. This combination will cause errors when the control is disposed (i.e. when the view is left). The grid control uses the select row mode, this may also be a requirement for this error to occur. Why this problem only happens every second time when I leave the view I don't know. This probably has something to do with the HMI internal data structures. I added one view as an example. The problem happens with Mod_GridAdjustmentPoints. I am aware that this is a very particular problem. Will this be fixed in the future? 2022-06-28 16:50:30 (A:1708324kB M:28261kB) [Error] <Application> Unhandled exception occured: System.ArgumentOutOfRangeException: Index was out of range.

I tried several more things, also putting the Mod_Grid into its own view without any other smart controls. I found that I can only make it scale the last column dynamically if I do not link any column data (VWItemColumnData). As soon as I specify an array here (I tried both strings and numbers), the width will not change anymore and be fixed to the value I set. Well, this does not seem quite intentional. Did you manage to make it work _with_ data?

Hello, This is for the HMI modulo 4.11.5.0. I am creating a station whose HMI will be displayed on screens with different screen resolutions. On a particularly busy page I am using Mod_Panels to stretch my controls according to the space requirements. In one of those panels I am using a Mod_Grid control with a single column. I set the anchors and the control is changing its size correctly as I am resizing the window. But my problem is that the column inside the Mod_Grid is not changing its size, making the dynamic resizing function sort of useless for this control. It always keeps the width I set for the column in Columns collection. The documentation promises that the last column would change its width to fill the entire Mod_Grid control, but that does not seem to be the case: I also tried various other settings, but no matter what I do, the width is fixed. Are there any solutions to this? Thanks in advance.

Hello, OES 4.11b user here. I am developing an object which has a structure that will most likely go into station data, which is often stored as a dat file. For the initial creation of the dat file I want to provide sensible initial values, which are sometimes not the default initial values of the data types. I found that the initialValue attribute does not seem to work on structure members that use enumRef. Using the .osd in OES seems to discard this information. Here is what I want to do: <Item name="CurveValue" enumRef="ATMOxAnalogInputArrayCurveValueEnum" initialValue="3"> <Properties> <Property name="Label"> <Text lcid="1033" value="Which value to display on the chart" /> </Property> <Property name="SelectEnumItems" value="True" /> </Properties> </Item> The initialValue seems to have no effect in OES, it is ignored. Apparently it's not possible to set initialValues for enums from .osd files at all, because I haven't found any that works. I can set it in the normal types definition in OES though, and when I activate "export STD files" the output also looks like my handwritten .osd above, but it doesn't work. Is there any plan to allow this feature in the future? For now my solution is to change the order of the enum items so my desired default coincides with index 0. If I needed different defaults for the same enum type in different places, then that would fail though.

Hello, I found 2 behaviors in OES v4.11b that I consider to be bugs. I created an object of type A and I found out that some parameters cannot be configured or do get lost when I reload STD. First of all, here is one such parameters: <ParameterVariable name="rInput" hierarchy="Input" refId="ATMOxPID_rInput" varType="LREAL" textEn ="bla bla." textDe="bla bla." subtreeInstanceSpecific="True" /> Now I have an object a. I cannot link object a's parameter to variables of object a's unit. I can select them in OES, but after I do the parameter is cleared again. I can link object a's parameter to the variables of object b's unit though, where object b is also of the same object type. But if I do that, then after reload STD the object parameter will be lost. If I link it to any other variable it seems to work fine. I think the problem is with the object's unit definition, which looks like this: <Unit refLink="A668CDB5-B088-4BC6-A09E-8151E9F1126A"> <Condition comparator="EqualTo" value="True" refLink="ATMOxPID_ExportFb"/> </Unit> <Unit refLink="7558CD31-B708-46CF-BB35-2426AC69D054"> <Condition comparator="EqualTo" value="False" refLink="ATMOxPID_ExportFb"/> </Unit> I guess when I reload STD it fails to recognize which of the two units I am using at the moment it is reloading the parameters, so it thinks the variable stopped existing. But why it immediately deletes my parameter selection if I select my own unit, I don't understand at all. Anyway, do you think this will be fixed in the future? Or do you have some more insight into this problem? Thanks.
