post-compiled textual replacement regex safety

hi I was wondering if there were any string-replace tokens that are less likely to conflict with gwt and closure output than just assuming a replacement token is unique

i have success with replacing "YOUR_CLIENT_ID" with oauth tokens to date, but if someone knows any more formal textual tokens that are likely to succeed with compiled gwt and closure after obfuscation, a pointer would be great.

so first, the assumption is that strings can be merged at compile time. then, not sure about this, but redundant or chunky similar strings might also be tokenized and recombined for whatever reason. if that's the case, it would be better to ask now than to hit that when going beyond the trivial example.

the usecase being solved is a non-template engine serving gwt content with a one-time replacement pass for "YOUR_CLIENT_ID" and maybe other vars as needed. as if compiling gwt to a jsp file, but not having or needing more than 1 or two replaced vars once per server startup.

TIA

Jim

Fwd: [gwt-contrib] Translated to null.nullField when using JsInterop & @JsType

Hello,

The newest @JsType feature is really very fascinating, and works in most cases. The only issue i found was the wrong null.nullField javascript output.

the compile command:

java -cp xxx com.google.gwt.dev.Compiler -war xxx -XnoclassMetadata -XnocheckCasts -XjsInteropMode JS -XclosureCompiler -style PRETTY com.goodow.realtime.store.StoreProd

Java code:

public CollaborativeOperation compose(JsonArray operations) {
final CollaborativeOperation first = operations.<CollaborativeOperation> get(0);

if (operations.length() == 1) {
return first;
}
final JsonArray components = Json.createArray();
operations.forEach(...);
return new CollaborativeOperation(first.userId, first.sessionId, components);

}

translated to the following javascript:

function $compose(operations) {
var components;

components = operations[0];
if (1 == operations.length) {
return components;
}
components = [];
$forEach(operations, new CollaborativeTransformer$1(components));

return new CollaborativeOperation(null.nullField, null.nullField, components);
}

There's an easy workaround to fix this: using the -draftCompile options when compilation. Here is the full compilation log:

Using GWT custom event and constructor

I have two panel.

Panel A send custom GWT event to Panel B to modify the appearance of Panel B.

The event bus is defined on their parent panel.

The event sending by event bus defined in other methods works after the initialization (constructor execution) of these 2 panels.

But, if I send an event in the constructor of Panel A to Panel B, the event handling doesn't work.

I can build a constructor of Panel B to initialize by parameters. But why the event sending from constructor doesn't work as expected?

Thanks

Re: reuse of private static variable

Make as many image instances as necessary. The browser will cache and reuse the src if it is identical.

The DOM acts like a tree with each node having exactly one parent node (except the root node which has no parent).
