Issues description:
in schememodel this javascript file, it define below property, but we can’t find RenderConext() functions in scheme namespace. does anybody find that?
this.renderContext = new scada.scheme.RenderContext();

have find the defination in schemerender, mark here

hi
All Guys
I meet some issues in schemerender.js file, it seems curCnlDataMap/imageMap are Map object, but I can’t find the inilization seems like imageMap=new map;
scada.scheme.RenderContext = function () {
this.curCnlDataMap = null;
this.editMode = false;
this.schemeEnv = null;
this.viewID = 0;
this.imageMap = null;
this.controlRight = true;
};

Hi,

RenderContext is created here.
imageMap is initialized here.

[ipqiusheng]

scada.scheme.SchemeRenderer.prototype._setTitle = function (title, renderContext) {
if (title && renderContext.schemeEnv.viewHub) {
document.title = title + ” – ” + renderContext.schemeEnv.viewHub.getEnv().productName;

// set title of a popup in case the scheme is in the popup
var popup = scada.popupLocator.getPopup();
if (popup) {
popup.setModalTitle(window, document.title);
}

// send notification about title change
renderContext.schemeEnv.viewHub.notify(scada.EventTypes.VIEW_TITLE_CHANGED, window, document.title);
}
};

Hi
Mikhail, thank you for your kind comment, how about this popupLocator, it is under scada namespace, but I can’t find that define

[Mikhail]

Hi,
I cannot find the above lines in scheme-render.js

[ipqiusheng]

Hi
Mikhail
sorry, I haven’t use version 6.0, I still look at your version 5.0 code, your code is very elegant，I still look at that, this is version 5.0 code, the popupLocator existed in schemerender.js. not sure where it is defined, but it looks like define in viewhub.js, but I can’t find that.

[ipqiusheng]

also, in basiccomprender.js, it also existed

[ipqiusheng]

hi
Mikhail
I put the link below my comments

[ipqiusheng]

thanks for your reply
Mikhail, I have used github to find this popup.js in webshell project, so I can’t find that in plscheme files. just mark here for other guys if someone have interesting in your code

[Mikhail]

Hi,
The popupLocator object is declared in popup.js, which is referenced by the web pages.

Hi
Mikhail and other guys, do you know what’s parsedData define?, it has property of ViewStamp and SchemeDoc object?
scada.scheme.Scheme.prototype._obtainSchemeDoc = function (parsedData) {
try {
if (typeof parsedData.ViewStamp === “undefined”) {
throw { message: “ViewStamp property is missing.” };
}

if (typeof parsedData.SchemeDoc === “undefined”) {
throw { message: “SchemeDoc property is missing.” };
}

if (this._viewStampsMatched(this.viewStamp, parsedData.ViewStamp)) {
this.type = “”;
this.props = parsedData.SchemeDoc;
this.viewStamp = parsedData.ViewStamp;
return true;
} else {
return false;
}
}
catch (ex) {
console.error(scada.utils.getCurTime() + ” Error obtaining scheme properties:”, ex.message);
return false;
}
};

[Mikhail]

Hi,
You should open the development tools in Chrome by pressing F12, set a breakpoint and check the actual data in the debugger.

ViewStamp is a stamp provided by server code to check that the client and server view data match.
SchemeDoc is a part of scheme object.
